Meta Ads GA4 Post-Click Quality
Compare Meta traffic to GA4 engagement and conversions to judge whether paid social traffic actually converts on-site.
Meta Ads and GA4 results for the most recent complete month 16/04/2026 - 15/05/2026. Meta reports strong click volume, but GA4 shows about 10 times less traffic after the click. That gap usually means attribution is overstating quality and the post-click experience is not holding up.
| Meta campaign | Clicks | CTR | CPC | Read |
|---|---|---|---|---|
| Broad Prospecting | 2,640 | 3.1% | GBP 0.94 | Looks strong in-platform |
| Lookalike 1% | 1,480 | 4.0% | GBP 0.81 | Good Meta efficiency |
| Retargeting | 1,020 | 6.8% | GBP 0.56 | Best native engagement |
| Interest Stack | 880 | 2.6% | GBP 1.08 | Cheap reach, weaker intent |
GA4 tells the post-click story. The traffic is much smaller, the engagement is weaker in the colder campaigns, and the conversion rate only looks healthy where intent is already strong. That is why the source mismatch matters more than the top-line click count.
| GA4 campaign | Sessions | Engaged sessions | Conversions | Read |
|---|---|---|---|---|
| Broad Prospecting | 268 | 101 | 10 | Traffic collapses after click |
| Lookalike 1% | 182 | 90 | 9 | Better than broad, still thin |
| Retargeting | 132 | 89 | 17 | Highest on-site quality |
| Interest Stack | 28 | 9 | 1 | Very weak post-click |
Retargeting is the cleanest campaign because it keeps the strongest relationship between Meta clicks and GA4 sessions. It still shrinks in GA4, but it holds up far better than broad prospecting, which tells us the problem is not just volume.
Broad Prospecting should be trimmed first because it looks acceptable inside Meta but converts into very little in GA4. When GA4 traffic lands at roughly one-tenth of Meta-reported clicks, that is a clear sign that attribution quality is weak and the post-click experience needs work before scaling further.
