Conversion tracking tells Google Ads which clicks turned into something valuable, like a form submission, phone call, WhatsApp message or sale. Without it, you, and Google's bidding, are guessing.
The most common problem we find in accounts we take over is tracking that's missing or wrong. Often only form submissions are tracked, while most leads actually come through WhatsApp or phone calls. The campaigns then look like they don't work, and Google's bidding optimises for the wrong thing.
That's why fixing conversion tracking is the first thing we do in every new account, before we change a single bid or keyword.

Most websites use the Google tag, usually through Google Tag Manager. You create a conversion action in Google Ads (Goals → Conversions), then fire it when the action happens on your site. Calls from ads are tracked with a Google forwarding number. Enhanced conversions add hashed customer details (like email) to improve accuracy as browsers block more cookies.
Mark the actions you want Google to optimise for as primary (like leads and sales). Mark softer signals as secondary (like page views or brochure downloads); they're reported but don't drive bidding. A common mistake is leaving page views as primary, which makes Google chase cheap, meaningless "conversions".
Submit a test enquiry, then check Goals → Conversions in Google Ads the next day. Google Tag Manager's Preview mode also shows whether each tag fired.
Yes. Smart Bidding strategies like Target CPA and Target ROAS rely entirely on your conversion data. Wrong tracking means Google optimises for the wrong thing.
