Difficulty in indexing

I was having difficulty indexing even with another site. That site had 600+ words per post and I had about twenty posts and link building. So I doubt this site’s problem is too little text, or posts generated by a plugin. Of course, they influence the results on Google, but I doubt that with 15k games I won’t place even one keyword that brings traffic.

Indeed, according to Search Console the keywords are half compared to the previous project. Ok, quality is better than quantity, but this is pure madness here.

I suspect I still have the same problem I had previously; There is a factor that consumes Google’s budget or causes the quality to drop monstrously.

These days I’ve found that programs like Pingdom and Gtmetrix don’t measure live site speed well. But on the staging site yes. https://postimg.cc/gallery/xNwtQxT. The staging site has an option to disable administrative authorization. On the previous site I didn’t have this problem. And if the problems of the old site and the current one depend on the login page or something else? Heck, I can’t place posts in the top 100 even with N/A on Ahrefs…. Not even 0 for Keyword Difficulty, but N/A! Or even easier…
