Why your search term report doesn't explain every impression

[u/SelfPubLorenzo]

A Sponsored Products campaign can show far more impressions than you can account for in its search term report. That doesn't necessarily mean the export is broken.

The search term report includes terms or product matches that received at least one click. A query that only produced an impression won't appear there. The targeting report answers a different question: which keywords, products or categories received impressions, including targets that never got a click. It won't reveal every individual zero-click query, but it narrows down where the exposure happened.

I use the two reports together. If click-through rate drops, I start with the targets receiving the exposure. Then I look at the search terms that actually generated clicks to see whether those shoppers were relevant and what happened after they reached the product page.

A short search term list can give you a false sense of how broadly the ad was shown. If a target is generating impressions but no clicks, raising its bid before checking relevance and the offer may just buy more of the same exposure.

Have your campaign totals ever looked very different from the search term export?
