How to Track Google Ads Conversions Properly (Most Small Businesses Get This Wrong)
Here is a question that will save you thousands of pounds a year: do you actually know which of your Google Ads are generating real business? Not clicks. Not impressions. Actual enquiries, phone calls, and sales. If you hesitated even slightly, you have a problem.
Running Google Ads without proper conversion tracking is like driving blindfolded and hoping you reach the right destination. You are spending money, sure. The car is moving. But you have absolutely no idea whether you are heading towards more customers or straight off a cliff.
We audit Google Ads accounts at DPOM every single week, and the same issue comes up time and time again. Conversion tracking is either missing, broken, or set up so badly that the data is meaningless. And the business owner has no idea because nobody told them to check.
The Numbers Tell a Brutal Story
Before we get into how to fix this, look at the scale of the problem. These figures should alarm any business owner who is spending money on Google Ads.
Let that sink in. More than half of small businesses are spending money on Google Ads without knowing what is actually working. And barely a quarter are tracking phone calls, which for most local businesses is the primary way customers get in touch. That is not a minor oversight. That is flying completely blind.
The third number is the one that should really get your attention. Businesses that track conversions properly see three times the return on ad spend compared to those that do not. Not because their ads are inherently better, but because they have the data to make smart decisions instead of guessing.
What Actually Counts as a Conversion?
This is where most confusion starts. A “conversion” sounds like marketing jargon, but it is simply any action a visitor takes that has value to your business. It is the moment a website visitor stops being a browser and becomes a potential customer.
The specific actions that count as conversions depend entirely on your business. For an e-commerce shop, a conversion is a completed purchase. For a plumber, it is a phone call or a form submission. For a solicitor, it might be someone downloading a guide or booking a consultation. There is no universal definition because every business is different.
The critical point is this: if you have not explicitly told Google what a conversion is for your business, Google has no way of knowing. It will happily take your money and show you clicks all day long. You have to define and configure your conversions yourself. Or, more realistically, you need someone competent to do it for you.
The 4 Types of Conversions You Should Be Tracking
Not all conversions are equal, and most businesses need to track more than one type. Here are the four categories that cover virtually every small business, along with why each one matters.
Form Submissions
Contact forms, quote requests, booking forms, enquiry forms. This is the bread and butter of conversion tracking for service businesses. Every time someone submits a form, that should be recorded as a conversion in Google Ads. If it is not, you have no idea which keywords and ads are generating your leads. Setup requires either a thank-you page trigger or an event tag on the form submission.
Phone Calls
For local businesses, phone calls are often worth more than form fills. A customer who picks up the phone is typically further along in their buying decision. Google Ads offers call tracking through forwarding numbers that appear on your ads and your website, recording which ad drove the call. If 70% of your enquiries come by phone and you are not tracking them, you are missing the majority of your conversion data. It really is that simple.
Purchases and Sales
If you sell products online, every completed transaction should be tracked as a conversion with its revenue value attached. This allows Google to calculate your actual return on ad spend, not an estimate. Without revenue data, you cannot tell the difference between a campaign generating £10 sales and one generating £1,000 sales. Both show as “1 conversion” but the difference to your bottom line is enormous.
Micro-Conversions
These are smaller actions that signal intent without being a direct lead or sale. Visiting a key page like your pricing page, downloading a brochure, watching a product video, or starting a live chat session. Micro-conversions help you understand the customer journey before the main conversion happens. They are especially useful for businesses with longer sales cycles where a visitor might need three or four visits before they are ready to enquire.
Most businesses should track at least the first two categories as primary conversions. Phone calls and form submissions together give you a complete picture of your lead generation. If your Google Ads account only tracks one of these, or worse, tracks neither, your data is fundamentally incomplete.
With Conversion Tracking vs Without: The Full Comparison
Still not sure whether this is worth the effort? Here is a direct comparison of what running Google Ads looks like with proper conversion tracking versus without it. The difference is night and day.
| Area | With Conversion Tracking | Without Conversion Tracking |
|---|---|---|
| Campaign Optimisation | Data-driven adjustments based on real results ✓ | Guesswork and gut feelings ✗ |
| Bid Strategy | Smart bidding optimises for actual conversions ✓ | Limited to manual or click-based bidding only ✗ |
| ROI Measurement | Clear cost-per-lead and return on ad spend figures ✓ | No idea if ads are profitable or losing money ✗ |
| Keyword Insights | Know exactly which keywords generate business ✓ | Only know which keywords get clicks, not results ✗ |
| Budget Allocation | Shift spend to campaigns that deliver leads and sales ✓ | Budget spread blindly across all campaigns ✗ |
| Campaign Decisions | Pause underperformers, scale what works ✓ | No basis for any strategic decisions at all ✗ |
Look at the “without” column. Every single decision about your ad spend becomes a guess. You cannot use smart bidding. You cannot tell which keywords are worth paying for. You cannot calculate your return on investment. You are throwing money at Google and hoping for the best.
Proper conversion tracking does not just give you nice reports. It unlocks Google’s most powerful optimisation tools. Smart bidding strategies like Target CPA and Maximise Conversions rely entirely on conversion data. Without it, you are locked out of the features that separate profitable campaigns from wasteful ones.
Why Most Conversion Tracking Is Set Up Wrong
Many businesses that think they have conversion tracking actually have it set up incorrectly. Bad tracking is arguably worse than no tracking because it gives you false confidence in data that is completely misleading you.
The most common mistake we see is tracking page views as conversions. Someone lands on your contact page and it fires as a conversion, even though they never submitted the form. Your account shows 200 “conversions” a month when you actually received 15 enquiries. If your conversion numbers in Google Ads do not roughly match the enquiries you are actually receiving, something is wrong.
Double-counting is another frequent issue. A single form submission fires the tag twice, or a page refresh triggers it again. Then there are missing conversions entirely – phone calls not tracked, forms on certain pages not tagged, purchases recorded without revenue values. Every gap in your tracking is a blind spot in your decision-making.
The Conversion Tracking Checklist
Use this checklist to verify whether your Google Ads conversion tracking is actually working. If you cannot confidently tick every item, your tracking needs attention.
- Google Ads tag is installed on every page of your website – not just the homepage, not just the landing page, every page.
- Form submissions are tracked correctly – test each form yourself and check that it fires exactly one conversion, not zero, not two.
- Phone call tracking is active – both calls from ad extensions and calls from your website should be recorded as conversions.
- Conversion counts match reality – compare Google Ads conversion numbers against your actual enquiries and sales for the same period. They should be in the same ballpark.
- Google Tag Assistant shows no errors – install the Tag Assistant browser extension and visit your website. It will flag any issues with your tracking tags.
- Conversion actions have correct values – if you are tracking different types of conversions, make sure each one has an appropriate value assigned. A phone call and a brochure download should not be weighted the same.
- Google Analytics and Google Ads data align – if both platforms show wildly different numbers for the same period, there is a configuration problem somewhere.
If you are unsure about any of these, do not just assume it is fine. Assumptions are expensive in Google Ads. Get it checked by someone who knows what they are looking at.
The Real Cost of Getting This Wrong
Say you are spending £1,500 a month on Google Ads. Without conversion tracking, you have no idea which half of that budget is working and which half is wasted. If even 30% of your spend goes to keywords that generate clicks but no business, that is £450 a month down the drain. Over a year, that is £5,400 you could have redirected to campaigns that actually make you money.
With proper tracking, you would shift that wasted spend into your best-performing campaigns. Those campaigns generate even more leads. The gap between a tracked account and an untracked account widens every single month because the tracked account gets smarter while the untracked one stays stuck. It is not magic. It is basic maths. You cannot optimise what you cannot measure.
Stop Guessing. Start Tracking. Start Growing.
If you have read this far and realised your conversion tracking is missing, broken, or incomplete, do not panic. But do act. Every day your tracking is not working is another day of ad spend decisions made on incomplete data. The sooner you fix it, the sooner every pound you spend on Google Ads starts working harder.
At DPOM, conversion tracking is the very first thing we audit and fix when we take on a new Google Ads account. We do not touch bids, we do not rewrite ads, we do not adjust budgets until we know the data is right. Because none of those optimisations mean anything if the measurement is wrong. Proper tracking is not a nice-to-have. It is the foundation everything else is built on.
