Google Ads conversion tracking means telling Google which clicks turned into something valuable, such as a form, a phone call or a WhatsApp tap, so you can see which keywords pay and so smart bidding can aim at real leads. You need the Google tag on your site plus one conversion action for each outcome.
Without it you are judging a campaign by clicks and cost, which tells you how much you spent and nothing about what it bought.
What should a small business actually track?
Track every action that a customer takes when they want to buy from you. For most local service firms that is three things: a form submission, a phone call and a click on a “call” or WhatsApp button.
Resist the temptation to count everything. Scrolling, page views and time on site belong in analytics, not in your Google Ads conversion column. If you let them in, bidding algorithms will happily hunt for people who scroll.
Decide which actions are primary. Primary actions are the ones bidding optimises towards. Secondary actions, such as a brochure download, are reported but ignored by bidding. Setting a vague newsletter sign-up as primary is a classic way to wreck a lead campaign.
How does the Google tag work with conversion actions?
There are two parts. The Google tag is a snippet that sits on every page of your site and recognises visitors who arrived from an ad. A conversion action is a rule in your account that says “when this happens, count it”.
The simplest route for a form is an event snippet that fires on the thank-you page. If your form does not redirect, which is common with Forminator, Gravity Forms or Contact Form 7, you need an event fired on successful submission instead. Google Tag Manager is the usual way to do this without touching theme code.
To set one up, go to Goals, then Conversions, then New conversion action, choose Website, and enter your domain. Google scans the page and suggests events. Pick the form one, give it a clear name like “Quote form submitted”, set the count to “One” for leads, and the attribution window to 30 days unless your buying cycle is long.
What are enhanced conversions and do you need them?
Enhanced conversions let you send hashed first-party data, usually an email address or phone number from the form, alongside the conversion. Google matches it against signed-in users to recover conversions that cookies would miss. Hashing means the details are scrambled before they leave the browser.
For lead forms, look for “enhanced conversions for leads”. It matters more now that browsers and consent choices cut visibility. Turn it on and accept the customer data terms in the account settings.
It will not rescue sloppy basics, though. Get the standard tag firing first. Then add this layer.
How do you track phone calls from Google Ads?
For many small firms, calls are the bulk of the leads, and tracking is usually missing for them. There are three call routes to know about.
Calls straight from the ad use a Google forwarding number on a call asset or call-only ad. You can count a call as a conversion once it lasts a set time, 60 seconds by default. Lower it to 30 seconds if your calls are short.
Calls from your website need a tracking number swap. Google’s website call conversion code replaces your number with a Google forwarding number for visitors from ads. The number must be visible on the page for it to work.
Clicks on a phone number on mobile are a separate conversion action, and they only show intent. Treat them as a weaker signal than a connected call.
If you want to know which keywords drive calls and hear them back, a third-party call tracking tool with recording is worth the £20 to £50 a month for most small firms, typical pricing. It also helps you spot whether staff answer promptly. Our guide to fixing Google Ads that is not working explains why that listening exercise often changes the campaign.
How does consent mode affect conversion tracking in the UK?
If your site shows a cookie banner, which UK rules on cookies and similar tech require for non-essential tracking, people who decline will not be tracked in the usual way. Consent Mode lets the Google tag adjust its behaviour according to the visitor’s choice, and Google then uses modelling to estimate some of the missing conversions.
Two points. The banner has to pass the consent choice to the tag properly, which a decorative banner that does nothing will not do. And you will see modelled numbers mixed with observed ones, so expect small differences between Google Ads and your own enquiry count. A gap of 10 to 20 per cent is not unusual. A gap of 70 per cent means something is broken.
How can you check Google Ads conversion tracking is working?
Use Tag Assistant, Google’s free tool, and load your site. It shows whether the Google tag loads and which events fire when you submit the form. Then do the test yourself with a phone and a laptop.
In Google Ads, the conversion action status should move to “Recording conversions” within about 24 hours of the first real hit. If it shows “No recent conversions” after you have tested, the tag is not firing, the event is wrong or consent mode is blocking it.
Finally, reconcile once a month. Compare conversions in Google Ads with the leads in your inbox or CRM. If Ads reports 22 and you received 15 form enquiries and 9 calls, that is fine. If Ads reports 60 and you received 15, you have duplicates.
What do you do with the data once it works?
Look at cost per conversion by campaign and by search term, not just the account total. Cut the terms that spend without converting, and give more budget to the ones that do. Only after you hold about 30 conversions in a month should you consider letting Target CPA take over.
Fees are worth a thought as well. Some agencies charge extra for tracking set-up, and some do not include it at all, which we cover in PPC management fees in the UK. Tracking behaves the same across paid social, and the cost side of Facebook advertising is worth comparing once you can measure a lead. The same applies to LinkedIn, where a single lead can be worth £100 or more.
All of this is set up as standard in our Google Ads management, with conversion actions named in plain English so you can read your own reports.
Frequently asked questions
How long does it take to set up conversion tracking?
A straightforward form and call set-up takes one to three hours, plus a day to confirm it records.
Do I need Google Tag Manager?
Not always. It is worth it when your form does not load a thank-you page or you plan to track more than two or three actions, because you can change things without a developer.
Should I import goals from Google Analytics?
Prefer native Google Ads conversion actions for bidding. Analytics imports are fine as a backup, but they arrive later and can double count if both are active.
Can I track WhatsApp enquiries?
You can track the click on the WhatsApp button, since the conversation itself happens off your site. It counts as an intent signal rather than a confirmed lead, so ask the customer how they found you and compare.
What if I am already spending and have no tracking?
Fix it now. Everything you spend until it is live teaches Google nothing, and you will not know which keywords were worth keeping. Painful, yes. But every week you wait costs more.
