Go to the queries section of this report, sort them according to position. Go through keywords were you rank low first page and early second page. Open the respective pages and compare your content as well as overall page optimization with those of sites/pages ranking at the top of page 1(top 3).
Optimize and improve these pages better and your rank and traffic should ideally improve.
The reason it works is that Google already considers your page worthy of ranking, but it just isn't enough to beat others above you.
Another thing is, filter the queries for questions, this depends on your niche. who, what, how, where etc. Open the SERP and see how the result for such keyword is being served, if it hasn't been overtaken by Google's AI search result, maybe you stand a chance when you answer those questions.
Finally, backlinks could be a factor but one needs to know what's going on in your niche first.
