Why are there fewer GA4 sessions than ad clicks?

Clicks and sessions are different metrics: some clicks never load the page, and consent and ad blockers stop some sessions being recorded. A small gap is normal; a large or growing one is worth investigating.

What causes 'Destination not working' in Google Ads?

Google's crawler couldn't load the page, got an error, or hit a redirect or block it couldn't complete. The Google Ads Destination Not Working Tester checks those signals.

Do I need UTMs on Meta and Reddit ads?

Yes. Neither platform adds UTMs for GA4 automatically. Without them, visits are classified by referrer or as Direct.

How often should I check landing pages?

Before launch and after every release that touches templates, consent, forms or scripts.

How these paid ads tools fit together

Paid traffic is bought before anyone checks the page it lands on. If the destination is slow, redirects badly, errors for some visitors, or loses its click ID before the ad tag fires, you pay for the click and get nothing measurable back. Worse, Google Ads may disapprove the ad for a destination it can't reach.

These tools check the landing side of your campaigns: whether a final URL is healthy and safe to spend on, what changed in your tracking after a release, and whether the clicks each platform reports actually arrive in GA4 as sessions.

Run the landing-page checks before launching or after any site release. Run the click-versus-session comparisons when a platform's numbers and GA4's drift apart.
