Don't blame the ads yet
When you see clicks with zero conversions, the instinct is to change your ads, rewrite your landing page, or adjust your targeting. But in most cases the ads are working fine. People are clicking, visiting, and becoming leads. The tracking just isn't capturing it.
Three common culprits
Your conversion tracking isn't set up. More common than you'd think. You set up campaigns, wrote ads, chose keywords, set budgets. But nobody configured conversion tracking. Google Ads literally can't count conversions because nobody told it what a conversion is.
Your tracking fires but on the wrong event. The conversion tag exists but it's attached to the wrong trigger — page loads instead of form submissions, button clicks instead of confirmed enquiries. Google either sees zero conversions (wrong trigger, never fires) or inflated numbers (fires on every page view).
Your conversions happen off-site. This is the big one. Visitors click your ad, visit your site, and contact you via WhatsApp, email, or phone. Real leads, real conversations, real revenue. But Google Ads sees zero conversions because the conversion happened outside the browser.
How to tell which it is
Open Google Ads and check if you have any conversion actions set up. If not, that's your problem. If you do, check whether they're recording any conversions at all. If they show conversions but the number seems wrong, your triggers are misconfigured. If they show zero and you know you're getting enquiries, your conversions are happening off-site.
The fix for all three
Tagless handles all three scenarios. It creates the conversion action in Google Ads for you (no manual setup). It detects conversion points automatically (no trigger configuration). And it tracks off-site conversions — WhatsApp, email, SMS — that GTM fundamentally cannot see.
One script fixes what might take hours of GTM debugging to diagnose, let alone repair.
