Google showing impressions but almost no clicks. why?

if competitors have stronger offers or better ad copy, they my get more clicks instead. small searches in messaging can affect CTR a lot.

the low ctr usually means the ad or keywords are not matching user intent and just try checking search terms testing new headlines and improving your ad message.

If impressions are coming but nobody is clicking, I first look at the headline and offer. It should give people a reason to click.

same thought.. You can try adjusting the keywords again, check what keywords your competitors are using, and try to follow their approach.

Most of the advice here is about changing the copy, but check your match types first. if you are running broad match without a massive negative list, google is just burning your impressions on completely irrelevant searches... check the actual search terms report. if you see junk, switch to phrase or exact and start aggressively building your negative list. copy won't save you if the traffic is completely wrong.
