Setting up conversion tracking in Google Ads: without it ads fly blind
A campaign without conversion tracking looks fine on clicks and impressions but can't say whether it produced a single sale. It's the most common technical gap in local accounts.
Why clicks and CTR don't substitute for conversions
Without a conversion goal, Google Ads optimises for clicks and reach — the only signals the system sees. A campaign with great CTR and a low click price can still produce zero sales, and without conversions there's no way to find out in time.
Automated bidding strategies — maximise conversions, target CPA, target ROAS — physically cannot work without tracked conversions: the algorithm has nothing to learn from and either fails to launch or defaults to manual behaviour.
A common picture in local accounts: ads run for months, spend is steady, and the question 'how many leads did this bring' stays unanswered because conversions were never set up.
What counts as a conversion
A baseline set for most sites: form submission, phone number click, Telegram or WhatsApp button click, and add-to-cart plus checkout for stores.
Phone clicks and messenger transitions are essential conversions for this market, where a large share of enquiries arrive by direct call or message rather than a form. An account tracking only the form misses most of the real demand.
Separate micro-conversions from macro-conversions: viewing three pages or adding to favourites can be tracked separately for behaviour analysis, but shouldn't be mixed with the primary goal — a lead or a purchase — when judging campaign performance.
Importing offline conversions and calls
Google's call tracking swaps in a dynamic phone number for the duration of an ad-driven visit and logs the call itself, with its duration, as a conversion — different from a simple mobile number click, which doesn't guarantee a conversation happened.
For businesses where the deal closes days after the call or chat — real estate, education, B2B — it's worth setting up offline conversion import: a manager marks in the CRM which leads turned into deals, and that data feeds back into Google Ads.
Without offline import the system optimises for enquiry volume rather than quality, and often starts bringing more cheap but irrelevant enquiries, since every lead looks equal to the algorithm.
Common tagging mistakes
Double-counting conversions is a frequent problem when the same event is logged both through the Google Ads tag and via Google Analytics 4 import without deduplication. It artificially inflates conversion counts and understates their real cost in reports.
Another common mistake is treating a 'thank you' page view as a conversion without checking it can't be reached directly by link or page refresh. That kind of tag inflates conversions with no real leads behind them.
Test conversions with a real submission right after setup: walk the user path from ad click to form submission and confirm the event shows up in Google Ads within a few hours at most.
