Google Ads Conversion Tracking: A Setup Checklist

Conversion tracking is the foundation of ad reporting

Google describes conversion tracking as measuring valuable actions people take after interacting with your ads, such as form submissions, calls, or online purchases. Without clear conversion definitions, you and any agency can only look at clicks and spend, and cannot tell whether ads bring real enquiries. Use this checklist before you appoint a manager.

1. Define what counts as valuable

Write down the business outcomes you want to track: an enquiry form, a booking, a started chat, a completed payment, or something else. One site can have several goals, but separate the main goal from supporting signals.

2. Separate a click from a successful submission

A click on a WhatsApp or "Enquire now" button shows interest. It does not confirm a conversation started, let alone that the visitor is a qualified lead. Prefer tracking a successful form submission or a received enquiry, such as a confirmation page or event, over counting button clicks. If you do track clicks, label them as supporting indicators.

3. Map each goal to its website steps

For each goal, list the pages or actions a visitor passes through, for example: ad landing page → form page → thank-you page. With a thank-you page, Google's website setup guide has you place the Google tag and then the event snippet in the head of the conversion page. If you use Google Tag Manager, follow its setup instead.

4. Confirm account and site access

Decide in advance who owns the Google Ads account, who can edit the website or Tag Manager, and who manages Google Analytics. Google notes that setup requires the ability to edit your website, so settle whether you, your developer, or the agency does it.

5. Understand the counting setting: every or one

Google Ads' count setting is either "Every" or "One" conversion. Google recommends "Every" for sales, where each transaction has value, and "One" for leads, so repeated form submissions from the same ad click are not counted as multiple enquiries.

6. Distinguish primary from secondary conversions

Google explains that conversion actions can be primary, used for bidding optimisation, or secondary, used for observation only. If every event is set as primary, automated bidding may optimise toward actions that do not matter. Do not include every event just to make the numbers look good.

7. Expect GA4 and Google Ads numbers to differ

Google Analytics 4 calls important events key events. Google Ads conversions created from them appear in advertising reports rather than standard Analytics reports, and this keeps counting consistent between the two. The platforms still have different reporting settings and attribution, so agree with your agency which report is the source of truth.

8. Verify before you spend

After setup, check the tracking status in Google Ads under Goals → Conversions → Summary, and use Google Tag Assistant to troubleshoot. Run the whole journey yourself with test data and confirm that a conversion counts once, that test traffic is kept out of real data, and that tracking behaves as expected given your cookie-consent settings, if you have a banner.

Handover checklist for an agency

• A written list of conversion goals, marked primary or secondary.
• The website steps or pages behind each goal.
• Named owners for Google Ads, Google Analytics, Tag Manager and the website back end.
• The count setting (every or one) and the reason for it.
• A verification record: test date, result and who confirmed it.
• The monthly reporting metrics you agreed, including which report is authoritative.
