Guys please help me. I bought an expired domain from 2021, apparently without spam and toxic backlinks. I started publishing 5-10 posts per day, the first 3 posts were indexed (and one ranked for kw multiple), then suddenly google stopped indexing the posts. I tried speedyindex, GSC etc but google does not index anything. Index another post for one day, and then disappeared. I dont understand why one article is ranked, while the others are not and are not even indexed. i noticed that there are still old pages indexed, if this can be useful to you.
