We run CPC programs on two sites. They both produce plenty of impressions for our ads.
To produce an impression, the searcher has to input relevant search terms - that will trigger our ads.
Keywords on both sites are very similar.
In both cases many searchers are triggering our ads.
On one platform we get an 8% CTR rate, on the other we only get 3% CTR
On both, searchers are responding to the same ads they have triggered by searching on relevant search terms
Am I missing something? How are the CTR rates so different?
