Should I delete pages with high bounce rate?

  Perry Bernard: GA bounce rate is not a ranking factor. If you are vaguely worried about that, fire an event on the page after 30 seconds of viewing the top-most DIV with GTM. This will give a more "true" view of people looking at the page for half a minute or more and reduce your "apparent" bounce rate without having to change the global GA pageview timeout off 30min. Also, you could trying implementing measurement to see if new users hitting those landing pages convert in later sessions, and what value that might have.

  Perry Bernard: FWIW this "trick" typically drops GA bounce rates immediately. If it doesn`t, it probably means your 85% bounce is genuinely bounce, and then yes, there`s gotta be something wrong between implied promise of what the page contains vs what it actually contains.
• 
  Perry Bernard: The bounce rate that affect rank is not really bounce, it`s "return to search". i.e. the rate at which a searcher returns to search results after clicking on a result. Google doesn`t use GA data to define this - it uses (hidden) Search Console data because the analytics in question here is happening on their property (Google.com) not yours.

  George G.: I agree with Perry Bernard. What i would add is - make a better CTA or popup on exit to a related resource on your site or w/e might interest them. You can also offer a freebie and gather emails. If the content gets traffic, use it.

  Michael Martinez: Google does not use any kind of bounce rate to adjust its rankings. They just confirmed this again. https://www.seroundtable.com/google-ignore-negative-seo...

  Ian MacLeod: We`ve always been reluctant to delete pages and these insights have given us a clear strategy with which we can move forward. With your advice in mind we have decided to keep the pages in place and develop some alternate offers to get some benefit from the traffic. Thanks Perry Bernard and George G. for the responses, appreciate your time :)
