If I'll be an X account with 1,000 followers will it be better than completely new account as far as "indexing" is the topic?X posts can help discovery faster, especially if the account is active and gets crawled regularly. I’d treat it as a supporting method, not a primary indexing strategy.
Can you recommend free strong SEO signal platforms?Posting on X can help with faster discovery, but it is usually not a strong SEO signal on its own. It is still useful for getting some visibility and encouraging indexing naturally.
