Google Ads conversion tracking tells Google which clicks turned into an enquiry, so it can find you more of them. For a local service business, count three things as your main results: calls from your ads, calls from your website, and form enquiries. Then send back the jobs you actually won, and keep everything else (direction clicks, taps on your number, page views) out of the count Google bids on.
A common mistake in small accounts looks like this. Google counts a mix of real enquiries and things that only look like them, reports a cheap cost per result, and spends your money buying more of the wrong thing.
What should a local business count as a conversion in Google Ads?
Count the actions that mean someone wants to hire you: a call that lasted long enough to be a real conversation, and a form that was sent. Everything else is a sign of interest at best, and Google should not be paid to chase it.
Google's help page on conversion measurement, checked on 12 November 2026, lists the main types: actions on your website, phone calls (from ads, to a number on your website, and taps on a number on your mobile site), imports from your own records, and local actions that Google records by itself. Here is how we would set each one for a trade, an accountant or a care agency:
| Action | Set it as | Why |
|---|---|---|
| Calls from ads (the call button on the ad) | Primary | A real phone conversation that started on your ad |
| Calls from your website (Google's forwarding number) | Primary | The same, for people who clicked through first |
| Form enquiry sent (thank-you page or confirmation) | Primary | Someone gave you their details and asked for help |
| Jobs won, uploaded from your records | Primary, once a few are coming in | The result you actually care about |
| Taps on your phone number on mobile | Secondary | A tap is not a call: it would count the same call twice |
| Directions and other local actions | Secondary | Interest in your location, often from people who already know you |
| Page views, time on site, brochure downloads | Secondary, or not at all | Cheap to get and unrelated to whether anyone books |
What a wrong setup does to the numbers
Say Gareth runs a two-man roofing firm in Chelmsford and spends six hundred pounds a month on ads. His account reports 40 conversions, so Google tells him each one cost fifteen pounds (six hundred divided by 40).
When he checks, whoever set up the account made direction clicks and taps on his number primary. Of the 40, 18 were clicks for directions, 12 were taps on his number that also show up as calls, and 10 were real enquiries. His true cost per enquiry is sixty pounds (six hundred divided by 10), four times what the dashboard said. Three of the ten became jobs, so each job cost two hundred pounds of ad spend, and that is the figure to judge the ads by.
Worse, Google bids for more of whatever it is told is a success, so Gareth's budget drifts towards people who wanted directions.
What is the difference between primary and secondary conversions?
Primary conversions are the ones Google bids on; secondary conversions are recorded for you to look at and nothing more. This split decides what Google spends your money chasing.
Google's help page on primary and secondary conversion actions, checked on 12 November 2026, says primary actions are "reported in the 'Conversions' column in your reports and used for bidding", while secondary actions "are used for reporting in the 'All conversions' column in your reports, but not for bidding". There is one exception: an action placed in a custom goal is used for bidding whichever way it is set, so check any custom goals as well.
To change an action, Google's page gives the route: in the Goals menu, open Summary under Conversions, find the goal, select Edit goal, choose Primary or "Secondary (observe only)", and save.
Local actions need a second look. Google's page on local actions conversions says they are "available in the 'All conversions' column" and that the goal is created automatically once your location assets are active. If anyone has added that goal to a campaign as a bidding goal, Google is buying direction clicks.
How do you track phone calls from Google Ads?
Turn on call reporting in your account settings, then create a call conversion action and set the minimum call length that counts. Google then puts a forwarding number on your ads and records each call's start time and length.
Google's help page on measuring calls from ads, checked on 12 November 2026, gives the route: Goals, Summary, Create conversion action, Conversions from phone calls, then the Phone call lead category, where you choose calls from ads, calls from website visits or calls via uploads. You need call reporting switched on and at least one call asset or location asset with a verified number. A call counts when it lasts longer than "a minimum duration that you set".
That minimum is your main filter. A wrong number or a sales call takes a few seconds; a real enquiry about a roof or a tax return takes longer. Our working rule is to start at around a minute and check it against your own call log after a month.
Two more points from Google's pages, checked the same day:
- The call reporting page lists the United Kingdom as a country where forwarding numbers work, and says Google records "call duration, call start time, caller phone number for calls over 15 seconds". A call from the call button on the ad is charged as a click.
- Google's AI-qualified call leads judge calls from their recordings, but its help page says call recording is "only available when both the dialling and receiving phone numbers are located in the United States or Canada". UK accounts do not get it, so call length is the only filter Google offers here.
Calls from your website
Many people click an ad, read your site, then ring the number on the page. Google's page on phone call conversion tracking explains that this uses "a Google forwarding number to dynamically replace your website number for users who clicked an ad". It needs the Google tag and a website call snippet on the site, so it is a job for whoever looks after your website.
People who find you any other way still see your normal number. Tracking calls from every source, including your Google Business Profile and leaflets, needs a call tracking tool, covered in our guide to call tracking for small businesses.
How do you track form enquiries?
Record a conversion when the form has been sent, and count one per click. A thank-you page that only loads after a successful send is the simplest trigger; a form that sends without changing page needs an event that fires on the confirmation message.
Google's help page on counting options, checked on 12 November 2026, offers "Every conversion" or "One conversion", where the second "counts only one conversion per ad click". For enquiries, one is right: a customer who sends the form twice is still one customer.
Test it the way a customer would: send the form from your phone and check the conversion appears in Google Ads within a day or so. To tell visits from your Google Business Profile or other ads apart from Google Ads clicks in your analytics, tag those links with our free UTM builder.
What are enhanced conversions for leads?
Enhanced conversions for leads is Google's way of linking an enquiry to the ad that produced it using the email address or phone number someone typed into your form. It makes your counts more complete, and it is the groundwork for telling Google which enquiries became paying jobs.
Google's help page, checked on 12 November 2026, describes it as "an upgraded version of offline conversion import that uses user-provided data, such as email addresses". Your website sends Google a hashed copy of the details, and "the hashed customer data is compared to hashed customer data of signed-in Google Accounts". Google's page on enhanced conversions says the hashing uses a one-way method called SHA256, so the details are scrambled before they leave your site.
Three points from the same page that older guides miss:
- Enhanced conversions for web and for leads are now one on and off setting.
- Google Ads Data Manager is the route Google points to for setting it up and for sending results back.
- From 15 June 2026, uploads through the Google Ads API moved to the Data Manager API, so older developer instructions for those uploads no longer apply.
In the UK, the ICO's guidance on cookies says consent "must be actively and clearly given" for anything beyond strictly necessary cookies, so your cookie banner decides whether Google's tag can use them. Google's page on consent mode says that when a visitor declines, its tags send cookieless signals that Google uses to estimate the missing results. Whoever runs your website should check the banner passes the visitor's choice through.
How do you tell Google which enquiries became paying jobs?
Keep a list of the enquiries that turned into work, and upload it to Google Ads on a regular day. Google then learns which searches bring paying clients, and which bring people who ring for a price and go elsewhere.
Google's help page on offline conversion imports, checked on 12 November 2026, says "we recommend starting with enhanced conversions for leads instead" of the older click ID method, and that Data Manager is "the fastest and easiest way" to set it up. It also reports that advertisers who added their own customer data saw "a median 10% increase in conversions compared to those using standard offline conversion imports". That is Google's figure across its advertisers; any one account may see more or less.
The practical rules for a small firm, from Google's offline imports FAQ checked the same day:
- Timing. A job can be uploaded up to 63 days after the click when you use enhanced conversions for leads (90 days with the older click ID method). Jobs that take longer to win need an earlier step uploaded instead, such as a quote accepted.
- How often. Google suggests daily uploads, or a steady schedule such as weekly if daily is not possible. For a firm winning a handful of jobs a week, a weekly upload is fine.
- What with. "A Google spreadsheet will also work." You do not need a CRM system. A sheet with the date, the email or phone number the customer used, and the job's value is enough.
Add the job value where you can. A boiler swap and a tap washer are both one job, and Google can only tell them apart if you tell it.
This feedback matters more as you spend more. Campaign types that let Google make more of the choices, such as Performance Max, need a steady flow of results to learn from, which is why we suggest local firms start on Search and add Performance Max for local businesses once the volume is there.
How do you check your conversion tracking is working?
Compare Google's count with your own records every week for the first month. If Google says 20 calls and your phone log shows eight that lasted more than a minute, something is counting that should not be.
A short checklist we use when we first look at an account:
- Open the conversions summary and read the list of primary actions. Anything other than calls, forms and won jobs should be secondary.
- Check custom goals and campaign goals for local actions or page views.
- Make a test call through the ad's call button (it costs one click) and send a test form. Both should show within a day.
- Check the minimum call length on each call action.
- Check the form action counts one conversion per click.
For a second pair of eyes, our free Google Ads audit asks fourteen questions about your account, including how it counts results, and names the three fixes that matter most.

Common questions
How does Google Ads conversion tracking work?
Google records each ad click, then watches for an action you have told it matters: a form being sent, a call lasting past your minimum length, or a job you upload later. When that action follows a click, Google credits the ad and the search behind it, and uses primary actions to decide what to bid on next.
Do I need Google Analytics for conversion tracking?
No. Google's help page says you can measure website conversions with Google Analytics, the Google tag, or both, and that call tracking through forwarding numbers needs no tag at all. Analytics is useful for seeing where every visitor came from, but the Google tag on its own is enough to count calls and forms.
What minimum call length should I set?
Google lets you choose, and does not publish a right answer for every business. Start at around a minute for a trade or professional service, since wrong numbers and sales calls rarely last that long. After a month, compare the counted calls with your own log and raise or lower it until the two agree.
Does tracking still work if visitors reject cookies?
Partly. With consent mode in place, Google's tags send cookieless signals for visitors who decline, and Google models the conversions it cannot see once your account passes a data threshold. Google's help page says call tracking through forwarding numbers needs no tag on your site, so calls from the ad itself do not depend on your cookie banner.
How long do uploaded jobs take to affect bidding?
Google's FAQ advises uploading for at least one and up to two full sales cycles before making an uploaded action primary. For a trade that quotes and books within a fortnight, that means about a month of weekly uploads. For longer sales, such as an accountant's annual engagement, upload an earlier step such as a signed letter of engagement.
What to do this week
Open your account's conversion summary and write down every primary action. Move anything that is not a call, a form or a won job to secondary, check the minimum call length, and make one test call and one test form. Then start a simple sheet of the jobs you win from ads, with the customer's email or phone number, so you have something to upload when you are ready.
