To get your profile links index you need to make a list of your profile links and follow these steps:

To make feed / RSS you can use IceRocket Free RSS Builder. Sing up and create RSS Channel. AT that channel click “Add Entry” or “Add Item” create post /entry, Insert your entry title and entry summary, in “Entry Link” form insert your profile page link that you want to indexed as backlink, one entry for one profile page until all of your link list already inserted. Now, click XML to see your feed / RSS, and use it as all of your profile page feed. Example : my profile page feed.

Insert your feed link to your page / post, so when spider crawling your page / post they will index that feed and index profile page link in the feed. Like I’ am doing, I insert my profile page feed above at the example.

As we all know that pages optimised on Google Hot Trends keywords are most likely to get indexed on search engine quickly. What I do is I use hottest trend keywords as my username on different forum and communities. I repeat those keywords in various section on profile. It works best with Vbulletin Forum Profiles which allow "Visitor Messages" with BBCode. Once you make any profile you can make a comment optimised on Google Hot trend keywords and bookmark it having "Hot Trend Keyword" in title of Bookmark. This will quickly index your profile.
