stuck on increasing search engine traffic

what does Search Console show? that's where i'd start before writing anything new. look for queries where you already get impressions at positions 8 to 20. those pages are nearly there, so improve them: answer the query more directly, tighten the title, add a section the top results cover and you don't, and link to them from your strongest pages. that usually moves faster than new posts. also check titles on pages with lots of impressions but a low click rate. a clearer title can lift clicks without any change in ranking.
