What is a search analytics service?

Question

Google

Actually there is a wonderful service https://ru.ahrefs.com/ but paid. I would like to find something similar, where you can score your project plus a dozen competitors and monitor them by the number of pages in the index, the number of referring sites, the number of backlinks, etc. in the form of graphs. Ideally, completely free or very cheap. Now we use this tool https://sites.pr-cy.ru/ free for up to 10 sites, but you have to manually update every day and write the indicators into a table, from which you can already build graphs.

Answer 1

It will definitely appear after servers and developers' time become free.
