Identi.ca is a free microblogging service that anyone can join and create groups on. Although I have not explored the service a great deal, I have created groups for some of my websites, and people have joined them. More importantly, Identi.ca is a PR8 website (meaning that its Google PageRank is 8), and backlinks created on the site are “dofollow,” which means that they can influence your PageRank. Some have even claimed that creating a group on Identi.ca has helped them get their website indexed quickly by Google. Here is the way to get your website listed on Identi.ca:
You now have a high-authority do-follow backlink to your website from a site with a PageRank of 8, and you may find that Google indexes your website more quickly if it is new. Use the “Site:” operator to see what pages of your website have been indexed by Google.
