How the title says, how to index my backlinks? I made backlinks with GSA SER, only Articles platforms because allow you to post content, the content is very important for the google updates so I create only relevant content even if is spun but I trying to do a readable content but unfortunately I get index only 10-15% of my backlinks. I post only on Drupal, Zendesk, Wordpress Article, XpressEngine, Article Script, Yad, Press Release, Joomla Blog, Buddy Press platforms. Also these sites where I post have min 1+ PR + Using GSA Indexer in full mode and still don't index more than 10-15%. Should I build backlinks(tier2) to my backlinks(tier1) ?
