How do you gain PR for squidoo lenses without link building, just internal linking? I know if you make the Top 100, you get a PR 5 or PR 6, but how do you build it just to a PR 3 or PR 4? The reason I ask is.. of course, links coming from higher PR pages give more credibility. Also, is there a trick to getting to the Top 100 easily and staying there for a niche very few people care about?
Update regularly, add all your tags, leave comments in squidoo, join groups, make groups, etc.. Still sorta hard with out building some links. Plenty of tools out there to help with that though - check out sitewidelinking for something that works good with squidoo pages.
Make sure you are on friendly terns with relevant lenses - offer crosslinking to the lense administrator
Squidoo is kind of interesting actually, in my opinion. You have to basically use SEO techniques to increase your lens. And since Squidoo is an SEO technique, your basically doing SEO on your SEO. Weird.
The nice thing about all the different Web 2.0 properties is that SEO for them is the same for our money sites, the bad thing is that there isn't any magic bullet. I don't think changing tags is going to help with SEO and PR for the lense, but to each their own. Use some profile links, that's usually the most efficient.
