You can have a Google Ads campaign that looks successful on paper and is still producing rubbish.
Google might report 30 conversions.
Cost per conversion might look reasonable.
Traffic might be up.
But when you actually speak to the people behind those conversions, half of them want something you don’t provide, live outside your service area, are looking for a job, aren’t ready to buy, or disappear the moment you return their call.
That is not a successful lead generation campaign.
The real question is not:
“How many leads did Google Ads generate?”
It is:
“How many of those leads had a genuine chance of becoming customers?”
Quick Answer
Poor-quality Google Ads leads are usually caused by loose keyword targeting, irrelevant search terms, incorrect location settings, weak conversion tracking, broad automation, poor landing-page qualification or campaigns optimising towards the wrong conversion actions.
Improving lead quality normally means tightening targeting, reviewing actual search terms, tracking qualified leads rather than every enquiry, improving landing pages and feeding better conversion data back into Google Ads.
Google Ads can measure website conversions and lead actions, but the quality of the data you feed into the platform matters because automated bidding uses those signals to decide where to spend.
1. You’re Optimising for Conversions, Not Qualified Leads
This is one of the biggest mistakes I see.
A conversion is simply an action you’ve told Google to count.
That action could be:
- a completed enquiry form
- a phone call
- a quote request
- a booking
- a button click
- a page visit
- a five-second call
- an old conversion action nobody remembered to remove
Google doesn’t automatically know which of those actions produced a worthwhile customer.
If you tell Google that all of them are equally valuable, you’re giving its bidding system poor information.
Google now specifically supports qualified lead and converted lead goals. A qualified lead can represent somebody you’ve assessed as genuinely promising, while a converted lead can represent somebody who moved further through your sales process.
That distinction matters.
Imagine you receive 20 enquiries.
Google sees 20 conversions.
But your sales team tells you:
- 6 were irrelevant
- 4 were outside your service area
- 3 wanted jobs
- 2 never responded
- 5 were genuine prospects
Your real result isn’t 20 useful leads.
It’s five.
That is the number you should care about.
2. Your Search Terms Are Attracting the Wrong People
Keywords aren’t the same thing as search terms.
You might bid on a keyword such as:
commercial roofing Sydney
But the searches triggering your ads could include variations you never intended.
This is why the Search Terms report matters.
I look for searches involving things such as:
- jobs
- salaries
- courses
- apprenticeships
- DIY
- free services
- cheap services
- unrelated products
- irrelevant suburbs
- competitors you don’t want
- consumer searches when you only work B2B
- information seekers with no obvious buying intent
One irrelevant click doesn’t matter much.
Hundreds of them do.
You can spend a surprising amount of money on people who were never realistic prospects in the first place.
3. Your Keywords Are Too Broad
Google has pushed advertisers steadily towards broader targeting and more automation.
Sometimes that works.
Sometimes it creates a mess.
Broad matching gives Google more freedom to decide which searches are relevant to your business.
That can work well when an account has strong conversion data and enough history.
But if the conversion signals are weak, Google may expand into searches that technically relate to your business while showing very little commercial intent.
For smaller lead-generation accounts, I often prefer tighter control until there is enough reliable data to justify opening things up.
This isn’t an argument that broad match is always bad.
It’s an argument that you shouldn’t give Google more freedom than your conversion data can support.
4. Your Location Targeting Is Too Loose
This sounds basic, but it still catches businesses out.
If you only service Sydney, you don’t want leads from Perth.
If you only service Greater Western Sydney, a lead from Newcastle may be equally useless.
And if you run a local trade business, even a lead 50 kilometres outside your normal service area may not be commercially worthwhile.
Location targeting needs to reflect:
- where you actually operate
- where you’re prepared to travel
- which suburbs are profitable
- which regions you want to avoid
- whether you want people physically located in the area rather than merely interested in it
This becomes even more important when clicks are expensive.
A $40 click from the wrong suburb is still $40 gone.
5. Your Landing Page Is Not Qualifying People
Most landing-page advice focuses on getting more conversions.
Sometimes you actually need the page to discourage the wrong people from enquiring.
That’s an important distinction.
If you only work with commercial clients, say so.
If your minimum project value is $5,000, consider making that clear.
If you only service particular locations, list them.
If you don’t provide emergency work, say that.
If you’re a specialist rather than a generalist, explain the distinction.
A good landing page shouldn’t simply maximise the number of people who complete the form.
It should help the right people recognise that you’re suitable and the wrong people realise that you’re not.
That can reduce raw lead volume while improving actual sales opportunities.
And that is usually a good trade.
6. You’re Counting Calls That Shouldn’t Be Conversions
Phone call tracking can be extremely useful for service businesses.
But poorly configured call tracking can make an account look better than it really is.
For example, if every phone call lasting five seconds is counted as a conversion, you might be including:
- wrong numbers
- accidental calls
- people hanging up immediately
- existing customers calling support
- suppliers
- job applicants
- callers asking for something completely unrelated
Setting an appropriate call-duration threshold can help.
But don’t assume longer automatically means better either.
A 90-second irrelevant enquiry is still irrelevant.
This is why businesses need to look at what actually happened after the conversion, not simply celebrate the number reported by Google.
7. Performance Max May Be Optimising Towards the Wrong Signals
Performance Max can generate leads.
Google explicitly positions it as one option for lead generation across its channels.
The problem is that Performance Max relies heavily on the quality of the signals you provide.
If your account tells Google:
“Any form submission is a win”
then Google will try to produce more form submissions.
It doesn’t inherently know that one enquiry became a $20,000 client while another was spam.
This is where stronger lead-quality data becomes valuable.
If you can tell Google which leads became qualified opportunities or customers, you’re giving the system a much better objective.
Without that feedback loop, businesses sometimes find themselves with impressive conversion counts and disappointing sales results.
8. Your Form Is Too Easy to Complete
This sounds counterintuitive.
Most conversion-rate advice tells you to reduce friction.
Remove fields.
Make the form shorter.
Ask for less information.
That can increase conversion rate.
It can also increase junk.
There is a point where a form becomes so easy to complete that it doesn’t qualify anybody.
You don’t need a 15-field interrogation.
But adding one or two useful questions can make a huge difference.
For example:
What service are you interested in?
Where are you located?
What is your approximate budget?
When do you need the work completed?
Are you a business or residential customer?
Those questions can improve both lead quality and the information available to your sales team.
9. You’re Judging Campaigns by Cost Per Lead Alone
Cost per lead is useful.
It is not the final metric.
Consider this:
Campaign A:
- 20 leads
- $80 per lead
- $1,600 spend
- 2 customers
Campaign B:
- 10 leads
- $140 per lead
- $1,400 spend
- 5 customers
If you only look at cost per lead, Campaign A wins.
Commercially, Campaign B may be far better.
This is why I prefer to know:
- how many leads were qualified
- how many became sales opportunities
- how many became customers
- average customer value
- profit margin
- sales cycle
- revenue generated
Google Ads becomes far more useful when advertising data and actual sales outcomes start talking to each other.
What Should You Track Instead?
At a minimum, I would separate your lead funnel into meaningful stages.
For example:
Enquiry
Somebody filled in a form or called.
Qualified lead
You confirmed that they are a genuine potential customer.
Opportunity
There is a realistic chance of a sale.
Customer
The lead converted into actual business.
Google recommends using lead-generation-specific conversion goals and supports qualified and converted lead actions for this reason.
The more valuable your leads are, the more useful this becomes.
If one new customer is worth $500, you may not need an enormously sophisticated CRM setup.
If one customer is worth $20,000 or $100,000, knowing which campaigns generate actual customers becomes much more important.
What I Would Check First in a Poor-Quality Lead Account
If I opened an account today and the business owner told me:
“We’re getting leads, but they’re rubbish.”
I wouldn’t immediately rebuild the campaigns.
I’d first check:
- Which conversion actions are Primary.
- What the actual search terms look like.
- Keyword match types.
- Negative keyword coverage.
- Geographic targeting.
- Call conversion settings.
- Whether Performance Max is involved.
- Which campaigns generate the poor leads.
- Whether the landing pages qualify visitors.
- Whether anyone is recording which enquiries become real opportunities.
That normally tells you far more than staring at the headline conversion number.
Should You Pause Google Ads If the Leads Are Poor?
Usually, no.
Poor lead quality doesn’t automatically mean Google Ads can’t work for the business.
It may mean the campaign is optimising towards the wrong outcome.
There are exceptions.
If the account is burning substantial budget with no sign of commercial intent, reducing spend while the problems are investigated can make sense.
But I would generally diagnose the cause before turning everything off.
A campaign with poor targeting can sometimes improve significantly once you remove the waste.
How Long Does It Take to Improve Lead Quality?
There is no fixed timeframe.
Some problems can be identified quickly.
Examples include:
- obviously irrelevant search terms
- incorrect locations
- broken conversion tracking
- inappropriate Primary conversions
- weak negative keyword coverage
Other improvements need more data.
If you change bidding signals, campaign structure or lead-quality tracking, you need enough volume before judging the impact properly.
The more lead data you can feed back into Google Ads, the easier it becomes to separate genuine improvement from random variation.
Google Ads Lead Generation Is Really a Data Quality Problem
Businesses often think lead generation success comes down to writing better ads.
That’s only one piece.
The bigger issue is often the quality of the information flowing through the account.
If you feed Google poor signals, it can optimise very efficiently towards the wrong outcome.
If you give it better information about:
- what searches matter
- what locations matter
- what services matter
- what counts as a genuine lead
- which leads become customers
then the system has a much better chance of producing commercially useful results.
Google’s own guidance increasingly reflects this approach, recommending lead-specific goals and better measurement of qualified and converted leads.
Getting Plenty of Leads, but Not Enough Good Ones?
That’s exactly the sort of account I like reviewing.
I look beyond the headline conversion numbers and check what Google is actually optimising towards, which searches are triggering the ads, where the budget is going and whether the tracking reflects genuine business outcomes.
If your Google Ads are producing activity rather than worthwhile enquiries, I can review the account and tell you where I think the problem is.
FAQs
Why am I getting irrelevant leads from Google Ads?
Irrelevant leads often come from loose keyword targeting, poor search-term control, incorrect location settings, weak negative keywords or campaigns optimising towards low-quality conversion actions. Start by reviewing the searches and campaigns producing those leads rather than judging the account only by its total conversion count.
Can Google Ads tell the difference between a good lead and a bad lead?
Not automatically. Google knows when a conversion action occurs, but it needs additional information to understand which leads became qualified prospects or customers. Google Ads supports qualified lead and converted lead conversion goals that can help improve this feedback loop.
Does Performance Max generate poor-quality leads?
It can, but Performance Max isn’t automatically the problem. Poor lead quality is more likely when the campaign is working from weak conversion signals, overly broad goals or insufficient feedback about which enquiries are genuinely valuable.
Should I use broad match for lead generation?
Broad match can work well in accounts with strong conversion data and enough volume, but it gives Google significantly more freedom to interpret search intent. In accounts with weak tracking or limited data, tighter keyword control may provide a better starting point.
How can I improve lead quality without increasing my Google Ads budget?
Start by reducing waste. Review search terms, negative keywords, locations, conversion actions and landing-page qualification. Improving the percentage of existing clicks that come from genuine prospects can be more valuable than simply buying more traffic.
Should I track every form submission as a Google Ads conversion?
You can measure every form submission, but that doesn’t necessarily mean every submission should carry the same optimisation value. If possible, distinguish between initial enquiries and leads that later prove to be qualified or converted.
What is more important, cost per lead or lead quality?
Lead quality. Cost per lead only becomes meaningful when you know what percentage of leads become customers and what those customers are worth. A more expensive lead can be substantially more profitable if it has a much higher close rate.
Can phone calls be tracked as Google Ads leads?
Yes. Google Ads supports conversion tracking for meaningful customer actions, including leads, and call-based conversions can form part of that measurement setup.
Should I stop Performance Max and only use Search campaigns?
Not automatically. Search campaigns often provide stronger control over explicit search intent, while Performance Max can broaden reach. The right structure depends on the account, conversion data, budget and quality of the leads being generated.
How do I know if my Google Ads campaign is actually profitable?
You need to connect advertising spend to real business outcomes. Track leads, qualified leads, sales opportunities and customers where possible, then compare acquisition cost with customer value and margin. Conversion counts alone are not enough.
