I think that ultimately it's simply a matter of the first few interacting a lot with your post; if they do, the rest will follow.
I check where the page is ranking. If it is on page 2 or 3, I usually improve the content instead of starting over.
I compare the article with top ranking pages and look for missing information, better examples, or sections that competitors are covering.
I usually compare the articles that r not perfforming well with the ones that r getting traffic. I confirm the content is relevant to search inttent, needs updating or could use improved internal linking. Sometimes a little fine tuning can make all the difference.
I also look at whether there is another page from that same website ranking for that same query. Often the content is gud, but it is not clear to google which URL should rank. sometimes fixing that focus will do more than writing more.
Usualy, what I would start with is analyzing the data from the GSC to see if the problem relates to the impresion, ranking or CTR. the content might be gud, but the page is not targeting the right intent or has no site-wide suport.
I generally verify if the page has impressions but no clicks or if it does not show up at all. This gives an idea about where the problem lies with respect to the title, content or search intent. Some modificatiions can be much better than starting from the scrattch.
For underperforming pages my method resembbles the diagnostic process. The first step is to find out if the page has any impresions without clicks or if the page is simply not discoverable. The next step is to assess the search intent, the competition the content nd the engagement signals. The remedy is often not in adding more words to the page but relevance.
