To actually benefit people, let's dissect things a bit together.
Here are my assumptions so let me know where you disagree.
- Links have value in the following order: cached, indexed, crawled, not crawled
- Uncrawled links offer no benefit because Google doesn't know about them
- Sites can rank with zero links indexed and zero links cached
- Profile links are very rarely found because they are so weakly linked. You may be a home page mention until other spammers push you off, so if you aren't there when G crawls your page will almost never be found.
- Linklicious knows when your links are crawled and pings until you get 100% crawl coverage.
