Quick Answer

For most established small to medium Shopify stores, an independent Google Ads consultant is often the strongest middle ground. You receive direct access to the person managing the account without the cost of hiring in-house or the layers of a larger agency. Larger retailers needing multiple specialists may be better suited to an agency or internal team.

The Three Main Google Ads Management Options for Shopify Stores

Choosing between a Google Ads agency, freelancer, independent consultant or in-house specialist is not simply a decision about price. You are deciding who will control an important source of website traffic, how closely your campaigns will be monitored and whether advertising decisions will be based on profitable sales rather than impressive-looking reports.

Shopify businesses generally have three options:

1. Hire a Google Ads agency.
2. Work with an independent Google Ads consultant or freelancer.
3. Employ someone in-house.

Each option can work. Each also has weaknesses that store owners often discover only after spending a considerable amount of money.

The right choice depends on the size of your business, advertising budget, internal resources, product range and how much direct attention your Google Ads account needs.

This guide explains the practical differences, what each option usually includes and what Shopify store owners should check before making a decision.

Why Shopify Google Ads Requires Specialist Knowledge

Managing Google Ads for a Shopify store involves more than creating a Performance Max campaign and increasing the budget.

The person managing the account may need to understand:

• Google Shopping
• Performance Max
• Search campaigns
• Google Merchant Centre
• Shopify product feeds
• Product disapprovals
• Shipping and tax settings
• Conversion tracking
• GA4
• Product margins
• Average order value
• New customer acquisition
• Repeat purchases
• Landing page performance
• Shopify theme and checkout limitations

A campaign can appear to be generating revenue while still producing poor commercial results.

For example, a report might show a return on ad spend of 400%. That sounds strong, but it may not be profitable once product costs, GST, shipping, discounts, payment fees and management costs are taken into account.

A capable Shopify Google Ads specialist should therefore look beyond clicks, revenue and the headline ROAS figure.

They should understand how advertising performance connects with the economics of the store.

Option One: Hiring a Google Ads Agency

A Google Ads agency usually has multiple employees and may provide several services, such as Google Ads, Meta advertising, SEO, content, email marketing and web development.

Agencies can range from small specialist teams to large organisations managing hundreds of clients.

Advantages of Hiring an Agency

A good agency may provide access to a wider range of skills.

Your account might benefit from input from campaign managers, designers, copywriters, developers, tracking specialists and strategy staff.

This can be useful when your store needs support across several areas rather than Google Ads alone.

An agency may also have systems for reporting, quality control, staff cover and account documentation. If one employee leaves or takes time off, another person may be available to manage the account.

For larger eCommerce businesses, this additional capacity can be valuable.

Disadvantages of Hiring an Agency

The biggest risk is not always the agency itself. It is the person who will actually manage your account.

The experienced strategist who leads the sales meeting may not be the person doing the day-to-day work.

After signing, your account could be assigned to a junior campaign manager responsible for a large number of clients. Communication may then pass through an account manager who is not personally making campaign changes.

This can create delays and make it difficult to get a clear answer about what is happening inside the account.

Some agencies also use standard campaign structures across many clients. Templates can improve efficiency, but Shopify stores do not all have the same margins, products, buying cycles or business objectives.

Another consideration is pricing. Larger agencies usually have higher overheads, which can result in higher monthly fees, longer contracts or charges based on a percentage of ad spend.

A percentage-based fee can create a potential conflict. The agency earns more when your advertising budget increases, regardless of whether the additional spend produces enough profitable sales.

This does not mean agencies are automatically a poor choice. It means you need to establish exactly who will manage your account and how decisions will be made.

A Google Ads Agency May Suit You If:

• You need several marketing services managed together.
• You have a large account requiring multiple specialists.
• You need extensive creative production.
• You operate across several countries or brands.
• You prefer an established team and formal account processes.
• Your business can support a larger monthly management fee.

Option Two: Hiring an Independent Google Ads Consultant

An independent consultant generally works directly with a smaller number of clients.

The person you speak with before signing is usually the same person reviewing search terms, adjusting budgets, checking conversion data and responding when there is a problem.

The terms “consultant” and “freelancer” are sometimes used interchangeably, although there can be a meaningful difference.

A freelancer may be hired primarily to complete assigned campaign tasks. A consultant should also be able to diagnose problems, challenge weak decisions and recommend a broader strategy.

Advantages of Working With a Consultant

The clearest benefit is direct access.

You can ask the person who is actually managing the account why a change was made, what the data shows and what should happen next.

Independent consultants also tend to manage fewer clients than larger agencies. This can allow them to develop a deeper understanding of the store, its products and its commercial priorities.

A specialist consultant may also have more flexibility.

They can adjust their approach around the business rather than forcing the account into an agency-wide process.

For Shopify store owners, the strongest consultants will understand how Google Ads interacts with Merchant Centre, product feeds, conversion tracking, landing pages and the store itself.

This matters because many apparent Google Ads problems originate outside the Google Ads account.

A product may not be receiving impressions because of a feed issue. Performance Max may be optimising towards the wrong conversion. A campaign may be attracting traffic, but the product page may not provide enough information to convert it.

A specialist who understands the whole system is more likely to identify the real problem.

Disadvantages of Working With a Consultant

An independent consultant has less capacity than a large agency.

If your business needs daily creative production, extensive development, international localisation and several advertising channels managed simultaneously, one person may not be enough.

You should also check what happens when the consultant is unavailable.

A professional consultant should have clear processes, account documentation and sensible communication expectations. However, they may not be able to provide the same level of staff redundancy as a larger agency.

The quality of independent consultants also varies considerably. Some are highly experienced specialists. Others may have completed a short course and begun selling campaign management services without substantial hands-on experience.

You still need to check their background carefully.

A Google Ads Consultant May Suit You If:

• You want to deal directly with the person managing your account.
• Google Ads is your main advertising priority.
• You run a Shopify or eCommerce business needing specialist support.
• You want practical advice without several layers of account management.
• You prefer a flexible, month-to-month arrangement.
• You value close attention over access to a large agency team.

Option Three: Hiring an In-House Google Ads Specialist

Hiring in-house means employing someone who works within your business rather than using an outside provider.

For a large enough eCommerce operation, this can provide the greatest level of day-to-day involvement.

Advantages of Hiring In-House

An in-house employee can develop a detailed understanding of your products, customers, margins, promotions and internal priorities.

They can work closely with merchandising, finance, customer service, developers and management.

They may also be able to react quickly to stock changes, promotions, new product releases and business decisions.

There is no need to brief an external provider every time something changes.

An in-house specialist can also spend their entire working week on your business, provided Google Ads and related performance marketing work are their main responsibilities.

Disadvantages of Hiring In-House

The cost is considerably more than the employee’s salary.

You may also need to account for superannuation, recruitment, software, equipment, leave, training and management time.

Finding one person who is genuinely strong across Google Ads, Merchant Centre, product feeds, analytics, tracking, Shopify and conversion optimisation can also be difficult.

A common mistake is hiring a general marketing coordinator and expecting them to manage technical Google Ads work alongside social media, email newsletters, website updates, events and content creation.

Google Ads then becomes one item on a long task list rather than a specialised performance channel.

An in-house employee may also have limited exposure to what is happening across other advertising accounts. Agencies and consultants often see patterns across several businesses, industries and campaign structures.

An In-House Specialist May Suit You If:

• Your Google Ads account requires substantial daily involvement.
• Your advertising budget justifies a full-time specialist.
• You have several brands or international markets.
• You run frequent promotions and product launches.
• You have enough internal work to keep an experienced specialist focused.
• You can recruit and retain someone with the required technical skills.

Google Ads Agency vs Consultant vs In-House Comparison

The table is only a starting point. The actual person managing your campaigns matters more than the label attached to the business.

A strong agency can outperform a weak freelancer. An experienced consultant can outperform a large agency team. A skilled in-house specialist can outperform both when the business has enough resources and support.

What Should a Shopify Google Ads Manager Actually Review?

Before appointing anyone, ask what they will examine beyond the visible campaign settings.

A proper Shopify Google Ads review may include:

Conversion Tracking

The manager should confirm that purchases are recorded accurately and only once.

They should check:

• Purchase value
• Transaction IDs
• Duplicate conversions
• Google Ads conversion tracking
• GA4 purchase events
• Enhanced conversions
• Consent settings
• Primary and secondary conversion actions

Campaign decisions will be unreliable when conversion tracking is incomplete or inflated.

Google Merchant Centre

Merchant Centre is essential for Google Shopping and most eCommerce Performance Max campaigns.

The manager should review:

• Product approvals and disapprovals
• Price mismatches
• Availability errors
• Shipping settings
• Product identifiers
• Product titles
• Product descriptions
• Product categories
• Images
• Promotions
• Feed update frequency

Increasing campaign budgets will not fix a weak or inaccurate product feed.

Product-Level Performance

Not every product should receive the same advertising investment.

The manager should be able to identify:

• Products generating profitable sales
• Products spending without converting
• Products with low margins
• High-value products receiving little exposure
• Products frequently out of stock
• Products attracting irrelevant searches
• Products that should be separated into different campaigns

A store-wide ROAS figure can hide serious problems at the product level.

Search Terms and Traffic Quality

Automation does not remove the need to review the traffic being purchased.

The manager should examine whether ads are appearing for searches that indicate genuine buying intent.

Irrelevant searches, research queries, job searches, support requests and unrelated products can consume a meaningful portion of the budget.

Campaign Structure

Campaign structure should reflect the needs of the store.

That could mean separating products according to:

• Margin
• Brand
• category
• Price
• Performance
• Stock availability
• Promotional priority
• New versus existing customers

There is no single campaign structure that is right for every Shopify business.

Landing Pages and Shopify Store Issues

A campaign cannot compensate indefinitely for a poor website experience.

The Google Ads manager should be willing to identify issues such as:

• Slow pages
• Weak product descriptions
• Missing delivery information
• Unclear returns policies
• Poor mobile layout
• Limited trust signals
• Confusing navigation
• Weak product images
• Complicated variant selection
• Unexpected checkout costs

They do not necessarily need to rebuild your website, but they should recognise when the website is limiting campaign performance.

Questions to Ask Before Hiring a Google Ads Agency or Consultant

Do not choose someone based only on a polished proposal or a convincing sales call.

Ask these questions directly.

1. Who Will Personally Manage My Account?

You want a name, not a department.

Ask whether the person on the sales call will remain involved after you sign.

2. How Many Accounts Does That Person Manage?

There is no perfect number, but the answer helps you understand how much attention your account is likely to receive.

3. What Experience Do You Have With Shopify Stores?

General lead-generation experience is not the same as managing Google Shopping, Merchant Centre and product feeds.

Ask for specific examples of the problems they have handled.

4. Will You Review Google Merchant Centre and My Product Feed?

If the answer is vague, be cautious.

For a Shopify store, the feed and Merchant Centre account can be as important as the campaign itself.

5. How Do You Decide Whether a Campaign Is Profitable?

Revenue and ROAS are not enough.

They should ask about margins, average order value, repeat purchases, shipping, discounts and the cost of acquiring a new customer.

6. How Often Will You Review the Account?

Be wary of answers that focus only on monthly reporting.

Reporting is not the same as active management.

7. Will I Keep Ownership of My Google Ads Account?

Your business should retain administrative ownership of its Google Ads, Merchant Centre, GA4 and related assets.

8. Are There Lock-In Contracts?

Ask what happens if you decide to leave and whether assistance is provided during the handover.

9. How Are You Paid?

Find out whether the fee is fixed, hourly or based on a percentage of advertising spend.

10. What Will You Need From Me?

A good provider will usually need information about margins, stock, promotions, business priorities and customer behaviour.

Google Ads should not be managed in isolation from the business.

Warning Signs When Choosing a Google Ads Provider

Be cautious when a provider:

• Guarantees a specific ROAS before properly reviewing the account.
• Recommends increasing the budget immediately.
• Wants to rebuild everything before understanding what is already working.
• Pushes every campaign into Performance Max.
• Never discusses Merchant Centre or the product feed.
• Reports revenue without asking about profitability.
• Cannot explain who will manage the account.
• Avoids giving you administrative access.
• Uses reports filled with clicks and impressions but little commercial analysis.
• Cannot explain campaign changes in plain English.
• Encourages you to approve every Google recommendation automatically.
• Has little practical experience with Shopify.

Google Ads involves uncertainty. No honest consultant can guarantee an exact commercial result.

What they should be able to provide is a clear process, accurate measurement, sensible decisions and transparent communication.

How Much Does Shopify Google Ads Management Cost in Australia?

Shopify Google Ads management may be charged as:

• A fixed monthly fee
• A percentage of advertising spend
• An hourly consulting rate
• A setup fee followed by monthly management
• A one-off audit or strategy project

The cheapest provider is not always the least expensive choice.

Poor conversion tracking, irrelevant traffic, weak product segmentation and unattended Merchant Centre problems can cost considerably more than the management fee.

At the same time, a high agency fee does not automatically mean the account will receive senior attention.

Compare what is actually included:

• Who performs the work
• How often the account is reviewed
• Whether Merchant Centre is included
• Whether feed optimisation is included
• Whether tracking is checked
• Whether landing pages are reviewed
• Whether reporting includes useful commercial analysis
• Whether you can speak directly with the campaign manager

A small store spending a modest amount each month will have different needs from an established retailer investing tens of thousands of dollars.

The service should match the size and complexity of the account.

Should You Get a Google Ads Audit Before Choosing?

A Google Ads audit can help you understand the current state of the account before committing to ongoing management.

A useful audit should examine areas such as:

• Conversion tracking
• Campaign structure
• Search terms
• Negative keywords
• Performance Max settings
• Product-level performance
• Merchant Centre
• Product feed quality
• Budget allocation
• Bidding strategies
• Landing pages

Avoid relying solely on an automated score or a list of Google recommendations.

The audit should explain what is happening, why it matters and what should be addressed first.

It should also distinguish between urgent problems and optional improvements.

Which Option Is Best for Most Shopify Stores?

For a large retailer with several brands, substantial creative requirements and international campaigns, an agency or in-house team may be the best option.

For a smaller store with a limited budget, a freelancer may provide affordable help with specific campaign tasks.

For an established small or medium Shopify business that wants experienced, hands-on Google Ads management, an independent specialist is often the most practical middle ground.

The store receives direct access to the person doing the work without taking on the cost of a full-time employee or the overhead of a larger agency.

However, the consultant must have genuine Shopify, Google Shopping and Merchant Centre experience. Hiring a generalist simply because they work independently does not solve the underlying problem.

Frequently Asked Questions

Is a Google Ads agency better than a freelancer?

Neither option is automatically better. An agency may provide a wider team and more services, while a freelancer or independent consultant may provide more direct attention. The right choice depends on the experience of the person managing the account, the complexity of your Shopify store and the amount of support you need.

Should I hire a Google Ads agency or an independent consultant for Shopify?

An agency may suit a large or multi-channel retailer needing creative, development and several marketing services. An independent Shopify Google Ads consultant may suit a small or medium eCommerce business that wants direct access to an experienced specialist.

What is the difference between a Google Ads consultant and an agency?

A consultant usually works directly with clients and personally manages a smaller number of accounts. An agency generally has multiple employees, departments and account managers. With an agency, it is important to confirm who will perform the day-to-day work.

What is the difference between a Google Ads consultant and a freelancer?

A freelancer may be hired to complete specific campaign tasks. A consultant should also be able to diagnose problems, advise on strategy and explain how Google Ads relates to the wider business. In practice, some experienced independent specialists perform both roles.

Is it better to manage Google Ads in-house?

In-house management can work well for a large Shopify business with enough advertising activity to justify an experienced full-time employee. Smaller businesses may find that an external specialist provides the required expertise at a lower total cost.

How do I choose a Shopify Google Ads specialist?

Look for practical experience with Shopify, Google Shopping, Performance Max, Merchant Centre, product feeds and eCommerce conversion tracking. Ask who will manage the account, how results will be measured, how often the account will be reviewed and whether you will retain ownership.

Does a Shopify Google Ads manager need Merchant Centre experience?

Yes. Google Merchant Centre supplies essential product information used by Google Shopping and eCommerce Performance Max campaigns. Feed errors, disapprovals, weak titles, incorrect shipping settings and pricing mismatches can directly affect campaign performance.

Should my Google Ads manager also review my Shopify store?

They should at least identify website problems that may be reducing conversions. These can include slow pages, unclear delivery information, weak product descriptions, poor mobile layouts, limited trust signals and checkout friction.

Should a Google Ads agency charge a percentage of ad spend?

Some agencies use percentage-based pricing, while others charge a fixed fee. Percentage pricing is not automatically wrong, but you should understand how the fee changes when your budget increases and whether the increase in spend is commercially justified.

Who should own my Google Ads account?

Your business should retain administrative ownership of its Google Ads account. You should also maintain appropriate ownership or administrative access to Merchant Centre, GA4, Google Tag Manager and other important marketing assets.

How often should a Shopify Google Ads account be reviewed?

Review frequency depends on advertising spend, campaign activity, promotions and data volume. The account should be checked often enough to identify tracking problems, budget issues, irrelevant traffic, product disapprovals and significant performance changes promptly.

Can a Google Ads agency guarantee results?

No reputable provider can guarantee a specific return because results are affected by competition, pricing, margins, website quality, demand, product appeal and other factors outside the campaign manager’s control. Be cautious of guaranteed ROAS or revenue claims.

Is Performance Max enough for a Shopify store?

Not always. Performance Max can be valuable, but some stores also benefit from Search, Shopping or other campaign structures. The right setup depends on the products, available data, search demand, margins and business objectives.

Why is my Shopify Google Ads ROAS high but profit low?

ROAS measures advertising revenue against advertising spend. It does not automatically account for product costs, GST, shipping, discounts, payment fees, returns or management costs. A campaign can have a positive-looking ROAS while producing limited profit.

How much should a Shopify store spend on Google Ads?

There is no universal minimum that suits every store. The appropriate budget depends on product prices, margins, conversion rate, competition, search volume and the amount of data needed to make useful decisions. The budget should be based on commercial reality rather than a generic recommendation.

Can I change Google Ads agencies without rebuilding everything?

Yes. A new manager should review the existing setup before deciding what needs to change. Rebuilding every campaign immediately can destroy useful historical structure and make it harder to identify what was previously working.

Should I get an audit before changing Google Ads providers?

An independent audit can help identify tracking errors, wasted spend, feed problems and structural weaknesses before you make a decision. It also gives you a clearer basis for comparing recommendations from different providers.

Does Yes Online Marketing work with Shopify stores outside Sydney?

Yes. Yes Online Marketing is based in Sydney and works with Shopify and eCommerce businesses across Australia. Campaign management, account audits and consultations can be completed remotely.

Who manages Google Ads accounts at Yes Online Marketing?

Phil Adair personally reviews and manages client Google Ads accounts. The work is not passed to a junior campaign manager or separate account management team.

What types of businesses are the best fit for Yes Online Marketing?

Yes Online Marketing is best suited to established Shopify and eCommerce businesses with proven products, realistic margins and enough advertising budget to generate meaningful data. It may not be suitable for an untested store expecting Google Ads to create demand for a product that has not yet demonstrated market interest.
