I came across an article that made me think mostly about SEO bots
In short, others analyze your website
and “steal” important content and keywords that they then include in their web pages
so in the end more people visit their pages and less yours.
so I blocked those bots on Cloudflare as well
That could also be the reason why you used to earn more, but today you earn less.
It’s always that war to be in the TOP 5 results from Google
as well as cover as many terms as possible that people might ask through search.
In addition, Google has changed its algorithms several times in the last 2 years and many pages that were once at the TOP have disappeared,
the results are also different depending on the GEO location.
