I just came across something terrific. I checked some of my backlinks (web 2.0) and saw that 70% (!) of them are not indexed. The most of them are about 7-10 days old. After creating them I let them run through the GSA SEO Indexer (Full Indexer ofc). Interesting thing is that 95% of the tumblr backlinks are not indexed. Whats up with tumblr? Doesn't get indexed anymore or what? So whats your experience with the SEO Indexer (if you are using it) and what Indexer can you recommend me (pls a one with a high indexing ratio)? Is it also a good way to make social bookmarks on the not indexed web 2.0s?
