i second you man... Indexing is important if you want to make use of the backlink, else it doesn't really mean anything since Google wouldn't know that it exists, unless it is crawled on its ownIndexing your tier 2 backlinks is really important for SEO because it boosts your main backlinks and helps your site rank higher. If you don't index them, your link-building efforts won’t be as effective.
Is there a difference between if I index the tier2 backlinks and not index tier2?
From my experience, if i don't index tier2 backlinks, i don't see good results,
what about you?
