I bought an expired domain on dynadot. The domain is clean, there has never been spam or strange backlinks. I set up the main pages and started publishing 5-10 posts per day. It indexed all the main pages (About us, contacts, privacy policy etc) and 3 posts (one of which was already on the second page since the first day), but for 4 days it has not indexed any other posts. I tried to submit some posts manually on GSC, create a subreddit (which has already been indexed) and I tried to change sitemap but nothing. Is it normal that the indexing stopped immediately? What can I do?
