Your Google Ads account isn’t delivering the results it used to. You’re spending money, enquiries are slowing down, and sales aren’t where they should be.
Perhaps your current agency keeps recommending a higher budget. Maybe you’ve been managing the account yourself and no longer know which settings to change.
You’re considering getting someone else involved, but there’s one thing holding you back.
Will fixing your Google Ads mean throwing away everything you’ve already built?
The good news is that, in many cases, it won’t.
An experienced Google Ads specialist can take over an existing account, identify what’s wrong and make substantial improvements without creating an entirely new account.
Some campaigns might need restructuring. Conversion tracking may need correcting. Budgets might need reallocating. But that doesn’t mean every campaign, keyword, audience or piece of historical performance data should be discarded.
I’m Phil Adair from Yes Online Marketing in Sydney. I work directly with businesses on Google Ads, Performance Max, Google Shopping and Shopify advertising.
My approach is straightforward: keep what’s working, fix what’s broken and only rebuild what genuinely needs replacing.
Here’s how I would assess an underperforming Google Ads account, what can usually be preserved, and what business owners should know before changing managers.
Quick Answer: Can Someone Fix My Google Ads Without Starting Over?
Yes. A Google Ads specialist can usually fix your existing account without starting from scratch.
Your account can retain its campaign history, historical performance reports, conversion data, keywords and existing campaign settings while a new specialist reviews and improves the setup.
Google Ads allows existing accounts to be linked to new manager accounts without changing the original account or its history.
However, there is an important distinction between preserving your account history and preserving a campaign’s current automated bidding behaviour.
Major changes to conversion goals, bidding strategies or campaign structure can require Google’s bidding systems to readjust. Keeping the same account does not guarantee that performance will remain unchanged during repairs.
The objective should be to improve the account with the least unnecessary disruption, not promise that nothing will change.
Why Starting Your Google Ads Again Is Usually the Wrong First Move
Imagine your business has been advertising on Google for four years.
During that time, your account has accumulated valuable information about:
Which keywords have generated enquiries or sales.
Which search terms have attracted irrelevant traffic.
Which products have historically performed well.
How conversion rates have changed.
Which locations produce stronger results.
How different budgets and bidding strategies have performed.
Which ads and landing pages have attracted customers.
When campaigns performed well and when results started declining.
Even if your campaigns are currently performing poorly, that information can help identify what went wrong.
Creating a completely new Google Ads account isn’t automatically going to improve performance.
In fact, it can introduce additional work, especially if conversion tracking, Google Analytics, Google Merchant Centre and other integrations need to be configured again.
There may be legitimate reasons for creating a new account, including some account ownership or billing situations. But poor campaign performance alone is rarely a sufficient reason.
A badly managed Google Ads account doesn’t automatically need replacing. It needs diagnosing.
That’s where I would begin.
What Can Be Kept When Someone New Takes Over Your Google Ads?
More than many business owners realise.
If you retain the same Google Ads account, the new manager can generally work with the existing campaigns and information rather than starting with an empty account.
| Account component | Can it usually be retained? | What I would check |
|---|---|---|
| Account history | Yes | Historical performance, reporting and changes |
| Existing campaigns | Yes | Whether the structure still makes commercial sense |
| Keywords and negatives | Yes | Relevance, coverage and wasted spend |
| Ads and creative assets | Yes | Performance, accuracy and opportunities to improve |
| Conversion tracking | Often | Whether it is accurate and correctly linked |
| Audience lists | Often | Ownership, eligibility and sharing arrangements |
| Performance Max campaigns | Yes | Conversion goals, product performance and targeting |
| Google Merchant Centre connections | Often | Feed source, access and linking permissions |
| Billing arrangements | Often | Who pays and whether a transfer is required |
There are some exceptions.
For example, tracking assets or audience lists controlled by a previous agency’s separate accounts may need to be replaced or reconfigured.
Shared tracking across a manager account can also create complications during a handover.
That’s why I would review access and ownership before removing an existing agency.
1. First, Find Out Why Your Google Ads Aren’t Working
This is the part I consider most important.
It’s tempting for a new agency or consultant to take over an account and immediately start making changes.
Pause the old campaigns. Build new ones. Change the bidding strategy. Rewrite everything.
It certainly looks like something is happening.
But activity isn’t the same as improvement.
Before touching a campaign, I want to understand what’s actually responsible for the poor performance.
Is the account attracting the wrong visitors?
Are clicks becoming more expensive?
Is the website converting fewer visitors into customers?
Are successful campaigns losing budget to weaker campaigns?
Or is Google Ads reporting conversions that don’t represent genuine business results?
Those problems require very different solutions.
Example: A Shopify store with falling sales
Imagine a Shopify store spending $6,000 per month on Google Ads.
Six months ago, its campaigns were generating consistent orders at an acceptable return.
Now the store is generating fewer sales even though advertising spend is unchanged.
The immediate reaction might be to rebuild Performance Max.
But that could be the wrong decision.
I would first investigate:
Whether the same products are receiving advertising spend.
Whether popular products have gone out of stock.
Whether product prices remain competitive.
Whether conversion tracking is counting purchases correctly.
Whether the Shopify conversion rate has declined.
Whether Performance Max is taking credit for existing customer or branded demand.
Whether Google Merchant Centre has product or shipping problems.
Whether website changes have affected navigation or checkout.
If the original campaign structure is reasonable, the solution might involve correcting tracking, improving product segmentation or addressing website problems.
A complete rebuild could be unnecessary.
2. Check Conversion Tracking Before Changing Bidding Strategies
One of the most damaging problems I look for is incorrect conversion tracking.
Google Ads uses conversion signals to help automated bidding decide which clicks and searches are valuable.
If those signals are wrong, the system can optimise towards the wrong outcomes.
When Google Ads reports conversions that aren’t real customers
Consider a lead-generation business.
It spends $3,000 on Google Ads and receives a report showing 30 conversions.
The reported cost per conversion is $100.
That might sound reasonable.
But suppose a proper account review finds that:
5 conversions were genuine enquiry forms.
15 were add-to-cart events.
10 were other website interactions.
The business didn’t generate 30 genuine enquiries. It generated five.
Its actual cost per genuine enquiry would be $600, assuming those five enquiries were correctly attributed to Google Ads.
That’s a very different commercial result.
This is an illustrative example, not a client case study.
Now imagine automated bidding has been optimising around that inflated conversion count.
Simply adjusting the campaign budget won’t address the underlying problem.
What I would review
I would inspect which conversion actions are being used for bidding, whether purchases or leads are being counted correctly, and whether duplicate events are inflating reported performance.
For Shopify businesses, this includes checking the relationship between Shopify orders, Google Ads purchases, GA4 events and the way revenue values are recorded.
For lead-generation businesses, I want to distinguish genuine enquiries from softer actions such as page views, button clicks and form interactions.
In most standard Google Ads goal configurations, primary conversion actions are used for bidding, while secondary actions are intended for observation. Custom goals have additional behaviour, so simply changing an action to secondary is not always enough.
Google provides detailed guidance on primary and secondary conversion actions.
The important thing is not to rush the corrections.
Changing conversion goals can cause automated bidding to readjust. I would plan the transition, establish a reliable measurement baseline and monitor the account carefully.
Better bidding cannot compensate for consistently misleading conversion data.
3. Fix Wasted Spend Before Increasing Your Budget
Another common situation is an account that spends its full budget but produces disappointing results.
The business owner asks why performance has deteriorated.
The agency recommends spending more.
Sometimes additional budget is justified. If campaigns are profitable and there is untapped demand, increasing spend may be a sensible commercial decision.
But if the existing account is wasting money, increasing the budget can magnify the problem.
Before recommending additional spend, I would look at where the current budget is going.
Search terms
Are people finding your ads through searches that have little commercial relevance?
For example, a business selling commercial UPS power systems may not want to pay for searches about home gaming equipment or basic consumer backup devices.
A business selling specialist coffee machines may attract searches for free manuals or unrelated repairs.
Search term analysis and appropriate negative keywords can help reduce unnecessary traffic.
Location targeting
Are your campaigns attracting customers in areas you don’t service?
Are location settings appropriate for the business and the campaign objective?
Bidding strategies
Are target CPA or target ROAS settings restricting useful traffic?
Are bidding targets based on reliable conversion data and realistic business economics?
Campaign budgets
Are profitable campaigns being restricted while weaker campaigns consume significant spend?
Could the existing budget be distributed more effectively?
Landing pages
Are visitors reaching relevant product or service pages?
Does the page answer their question and provide a clear next step?
Sometimes fixing these problems is more valuable than building another campaign.
4. Can an Existing Performance Max Campaign Be Fixed?
Yes, and I would be particularly careful about automatically replacing Performance Max campaigns that have previously generated useful sales.
Performance Max can work well for Shopify and eCommerce businesses, but its performance depends on more than the campaign settings alone.
I would examine the conversion goals, product listings, asset groups, campaign segmentation, search insights, brand traffic and how budget is being distributed.
For an established Shopify store, one of my biggest concerns is whether spend is being concentrated on the right products.
The hidden problem with an acceptable overall ROAS
Imagine an account reporting a ROAS of 3.0.
At first glance, that’s $3 of attributed revenue for every $1 spent on advertising.
But a closer inspection might reveal that a small number of popular products are responsible for most of the revenue, while other products continually consume budget without producing worthwhile returns.
That doesn’t necessarily mean those weaker products should all be excluded immediately.
Some products have different margins, longer purchase cycles or assist other sales.
But it does mean they need to be investigated.
I might recommend changing product segmentation, improving the product feed, reviewing bidding targets or testing a different campaign structure.
For some businesses, Standard Shopping versus Performance Max is also worth revisiting.
The right decision depends on the products, available data and business objectives.
The question isn’t whether Performance Max should stay or go. It’s whether the existing campaign is helping you acquire profitable customers.
5. Your Google Merchant Centre Could Be Part of the Problem
This is especially relevant to Shopify stores.
A Google Ads account can appear reasonably configured while important problems sit outside Google Ads itself.
Google Merchant Centre determines whether products are eligible to appear in Shopping ads and provides product information that Google uses to match products with relevant searches.
Problems can include:
Products being disapproved.
Incorrect stock availability.
Price mismatches between Shopify and the product feed.
Shipping information that doesn’t match the website.
Missing or incorrect product identifiers.
Poorly written product titles.
Product feeds that aren’t updating correctly.
Important products missing from the submitted feed.
These issues can affect advertising eligibility, visibility and performance.
Creating new campaigns won’t resolve an incorrect product feed.
If I’m reviewing a Shopify advertiser, I want to inspect the connection between Shopify, the feed application, Merchant Centre and Google Ads before recommending campaign changes.
You can read more about Google Merchant Centre problems that hurt Shopping ads.
6. Should You Repair Existing Campaigns or Rebuild Them?
This is where experience matters.
I don’t believe every campaign should be preserved simply because it has historical data.
Equally, I don’t believe every campaign should be replaced just because a new manager has a different preferred structure.
I divide an account into three categories.
Keep: Campaigns that are already doing their job
If a Search campaign is generating qualified leads at an acceptable cost, I want a very good reason before making major changes.
The same applies to a Shopping campaign consistently selling profitable products.
There may be opportunities for improvement, but that doesn’t automatically justify a rebuild.
Fix: Campaigns with identifiable problems
Many underperforming campaigns fall into this category.
The targeting might be too broad. Negative keywords may be missing. Conversion tracking may be incorrect. Budget allocation might be poor.
These are problems that can often be addressed within the existing campaign.
The changes still need to be monitored, but the entire campaign doesn’t necessarily need replacing.
Rebuild: Campaigns with structural problems
Sometimes the original setup is genuinely unsuitable.
Examples include:
Campaigns combining unrelated services with different customer intentions.
Product groups with substantially different margins or performance requirements competing for one budget.
Conversion strategies that no longer reflect the business objective.
Campaign structures that make budget control or performance analysis unnecessarily difficult.
Old campaign setups that no longer support the business’s requirements.
In those situations, I may recommend building replacement campaigns inside the existing Google Ads account.
That allows the business to retain account-level history while introducing a more suitable structure.
New campaigns may still need time to develop reliable performance. They don’t automatically inherit every aspect of the old campaign’s learning.
My preference is to make changes based on evidence, not to replace campaigns for the sake of it.
7. Will Changing Your Google Ads Manager Reset the Learning Period?
Changing managers does not, by itself, require you to reset your existing Google Ads campaigns.
If your business keeps the same account and campaigns, a management handover isn’t equivalent to launching a completely new advertising account.
However, significant campaign changes can affect automated bidding.
Google explains that changes to bidding strategies, conversion goals and campaign composition may trigger a learning period.
The duration depends on several factors, including conversion volume, conversion delay and the bidding strategy.
Google’s guidance indicates that calibration often takes one or two conversion cycles, although the actual period can vary.
A competent specialist should understand that distinction.
I wouldn’t promise that a complicated account can be restructured without short-term performance fluctuations.
Instead, I would aim to manage the transition carefully.
That might involve preserving campaigns that are working, correcting the highest-priority problems first, monitoring conversion data and avoiding unnecessary changes to everything at once.
Google explains the process in its documentation about the learning period for automated bidding.
If someone tells you every campaign must be deleted because a new manager is taking over, ask them to explain the technical reason.
8. How Do You Change Google Ads Agencies Without Losing Your Account?
This is something I would encourage every business owner to understand.
Your advertising account is a valuable business asset.
You should know who can access it, who controls its billing arrangements and whether you have the administrative permissions needed to manage it independently.
Step 1: Confirm that you have administrative access
Sign into your Google Ads account.
Open Admin > Access and security and review the users and managers.
Make sure you have appropriate administrator access through an account you control.
If you don’t, resolve that before ending your relationship with the current agency.
Step 2: Check who controls billing
Review the account’s billing settings and payments profile.
If Google bills your business directly, the transition may be relatively straightforward.
If advertising spend is billed through the agency’s payments profile or a monthly invoicing arrangement, a separate billing transfer may be required.
You don’t want payment issues unexpectedly interrupting your advertising.
Step 3: Give the new specialist access
A new Google Ads manager can send a request to link your existing account using its Google Ads customer ID.
An authorised administrator can accept the request.
For an initial assessment, read-only access may be sufficient. It allows a specialist to investigate without modifying campaigns.
There’s no need to hand over your personal Google login password.
Step 4: Review the account before changing anything
The incoming specialist should examine the existing setup and establish which campaigns are worth retaining.
Where possible, I would also confirm access to GA4, Merchant Centre, Tag Manager, Shopify and any systems used to record leads or sales.
Step 5: Agree on the transition
Before removing the previous agency, confirm the handover arrangements, existing contract terms, billing responsibilities and any tracking or integrations the agency controls.
Once access and dependencies are secured, the old agency’s manager account can be unlinked when appropriate.
Google confirms that unlinking a manager doesn’t delete the individual Google Ads account’s campaign history.
For official instructions, see Google’s guidance on unlinking manager accounts.
9. What Should a New Google Ads Specialist Do in the First 30 Days?
If I take over an existing Google Ads account, I don’t want to spend the first month making random changes simply to prove that something is happening.
I want to establish a clear understanding of performance and work through the problems in a sensible order.
Here’s an example of how I would approach the first month. The actual sequence depends on the account’s condition and the urgency of its issues.
Days 1 to 7: Understand the account
Review historical performance, conversion tracking, campaigns, budgets, bidding strategies, search terms and change history.
For Shopify businesses, review product performance, Merchant Centre and the product feed.
Identify the most serious issues and establish a reliable baseline.
An urgent tracking or website problem may need attention immediately.
Days 8 to 14: Address the biggest problems
Prioritise corrections that have a clear commercial justification.
That might mean excluding irrelevant searches, correcting conversion goals, improving targeting or addressing Merchant Centre errors.
I would be cautious about making several major changes simultaneously without a way to assess their impact.
Days 15 to 21: Improve campaign structure where necessary
Review how budget is distributed and whether the existing campaign structure makes sense.
Introduce replacement campaigns or controlled tests where appropriate.
Keep productive campaigns running unless there is a clear reason to change them.
Days 22 to 30: Evaluate progress and refine the plan
Review the initial changes, conversion quality, advertising spend and early performance indicators.
Some changes may show useful results quickly. Others need more data and time.
The objective is not to claim that a poorly performing account can always be fixed in 30 days.
It’s to establish what was wrong, implement justified improvements and create a reliable plan for ongoing optimisation.
At the end of the first month, you should know considerably more about where your advertising budget is going and what needs to happen next.
10. What Does It Cost to Fix an Existing Google Ads Account?
The cost depends on what is wrong and how much work is required.
There are three common situations.
An independent Google Ads audit
An audit identifies problems and recommends changes.
This may be appropriate if you already have someone managing the account but want an independent assessment.
The audit itself doesn’t necessarily include implementing every recommendation.
A Google Ads audit and repair
This goes further.
The specialist reviews the account and implements agreed corrections to tracking, targeting, campaign structure or other issues.
It can be appropriate when the account needs substantial technical or strategic work before regular management resumes.
Ongoing Google Ads management
For many businesses, the account needs ongoing attention after the initial repairs.
This includes monitoring results, managing budgets, reviewing search terms, improving ads, testing changes and maintaining accurate conversion tracking.
The right option depends on the condition of the account and whether you have the resources to manage it properly afterwards.
For more detail, see my guide to Google Ads management costs in Australia.
11. Five Questions to Ask Before Hiring Someone to Fix Your Google Ads
Before handing your account to a new agency or consultant, I would ask these five questions.
1. Will you review my existing campaigns before recommending a rebuild?
You want someone who is willing to understand the history rather than apply the same structure to every client.
2. How will you check whether my conversion tracking is accurate?
If they only look at reported conversions without questioning what those conversions represent, I’d want to know more about their process.
3. Can you work with my existing Google Ads account?
A good specialist should understand manager-account access, account ownership and campaign history.
4. Will you review my website and landing pages as well?
Google Ads performance depends partly on what happens after the click. For Shopify businesses, this also involves product pages, the shopping experience and product data.
5. How will I know what has been changed and whether it’s working?
Ask for clear explanations, meaningful reporting and a plan based on actual business outcomes.
You don’t need someone who makes Google Ads sound complicated.
You need someone who understands the complicated parts and explains them properly.
12. When Is It Better to Start Google Ads Again?
Although I generally prefer to preserve a usable account, there are situations where rebuilding parts of the advertising setup makes sense.
For example:
The business has changed its products, services or target customers substantially.
Existing campaigns have structural problems that would be difficult to correct cleanly.
Conversion tracking needs to be redesigned.
The original campaign strategy is no longer commercially relevant.
Separate businesses or legal entities require different account arrangements.
Account access, ownership or billing complications require a different setup.
Even in these situations, I would distinguish between rebuilding campaigns and creating an entirely new Google Ads account.
They aren’t the same thing.
You can replace a campaign structure within your existing account without deleting the historical account records.
And a new account should never be created as a workaround for an account suspension or Google Ads policy enforcement.
Frequently Asked Questions
Can a Google Ads expert fix my existing campaigns?
Yes. A Google Ads expert can review and modify existing campaigns, including keywords, negative keywords, budgets, bidding strategies, targeting and conversion settings. Some campaigns may benefit from restructuring, but creating a new Google Ads account is not usually necessary.
Will I lose my Google Ads history if I change agencies?
Not if you retain your existing Google Ads account. Google allows an individual account to be linked to a different manager account while preserving its history. Before changing agencies, confirm that you have appropriate administrative access and that billing and tracking arrangements are secure.
Can I keep my Performance Max campaigns when changing agencies?
Yes. Existing Performance Max campaigns can remain in the same Google Ads account when a new manager takes over. Whether they should remain unchanged depends on their structure, conversion tracking, product performance and commercial results.
Will Google Ads start learning again if I change managers?
Changing the person or agency managing an existing account does not itself require new campaigns or a learning reset. However, changes to bidding strategies, conversion goals and campaign composition may cause automated bidding to readjust.
Can I hire someone just to repair my Google Ads account?
Yes. You can engage a Google Ads specialist for an audit, a defined repair project or ongoing management. The right arrangement depends on the account’s condition and whether someone can maintain the improvements afterwards.
Can a new Google Ads agency see what my previous agency did?
Google Ads provides a change history showing many account and campaign changes over the past two years, including applicable changes made by users and automated tools. A new manager with appropriate access can review this information alongside historical performance reports. Not every activity or decision is recorded.
Should I pause all my Google Ads while someone fixes them?
Not automatically. Pausing every campaign could unnecessarily interrupt enquiries and sales. A specialist should assess which campaigns should remain active, which need changes and whether any are wasting enough money to justify pausing.
What if my old agency created my Google Ads account?
Start by confirming who has administrative access, who controls the payments profile and whether the account can be managed independently. In many cases, the existing account can be retained, but an agency-controlled billing or ownership arrangement may require additional steps.
How long does it take to fix a poorly performing Google Ads account?
Some problems, such as obviously irrelevant keywords or straightforward tracking errors, can be identified and addressed relatively quickly. More extensive restructures and changes to automated bidding can require several conversion cycles before performance can be assessed reliably. The timeframe depends on the complexity of the account, conversion volume and the type of changes needed.
Is it better to fix Google Ads or hire a new agency?
These aren’t mutually exclusive. A different agency or independent consultant may be able to repair your existing account without rebuilding everything. Before changing providers, establish whether the problem is campaign management, incorrect tracking, website performance, market conditions or a combination of factors.
My Advice: Don’t Throw Away Your Google Ads History Without a Good Reason
If your Google Ads account is underperforming, I wouldn’t automatically recommend starting again.
I’d want to see what’s happening first.
There may be campaigns worth keeping, conversion tracking that needs correcting, wasted spend that can be reduced or website problems affecting your sales.
Equally, there may be serious structural issues that justify rebuilding some campaigns.
The important thing is making that decision based on evidence.
After years of working with Google Ads, one thing I’ve learned is that the answer isn’t always to create more campaigns, increase the budget or make the account more complicated.
Sometimes the biggest improvement comes from identifying what was already wrong.
