Im currently running a pmax campaign for a holiday company that primarily sells package holidays to bulgaria, catering for both summer holidays and winter holidays, im running a pmax for winter holidays, using final URL expansion but excluding summer pages, blog pages etc, the issue im encountering is in the insights report, I am still getting lots of summer related searches, is there a way around this?

So I am running Google Ads for a client (they are a tour operator for holidays to Bulgaria), I have recently taken over this account, back in July 2023 it had various search campaigns doing very well 40+ conversions a month £12-20 CPA, Google however applied an automatic recommendation to this (target ROAS of 8000%) this completely crashed this campaign (as the person running it before failed to notice. I am now struggling to get most of my search campaigns converting at all (for example i have a campaign targeting hotels by location, with each ad set an individual hotel), however I am unable to get my CPA below £150 for a campaign that was getting £10 conversions previously.... any help would be HUGELY appreciated .. happy to provide more information if needed
