I built this little GPT that will let you upload an exported file from Google Search Console and it will look for the top opportunities for you to target.
You can upload a file from a single page or from the entire site, but remember that GSC restricts you to 1000 search queries, so on a bigger site it would be best to filter the results somehow first.
I like going by page, but you could also use a regex expression to narrow down by a list of queries.
Once you have exported the file, just upload it to this GPT and it will begin an analysis.
It will report on the top 10 opportunities it found and then prompt you to download a list of the top 50 it found.
Note: It may not go the whole way up to 50. It depends on the data you feed it.
What it is pulling are the top query opportunities that rank outside the top 30. These are search terms that are potentially being underserved by your existing content or perhaps not even really targeted at all.
