I've been thinking about Squidoo for a while also...
It's not because I like Squidoo... In all honesty, i've been thinking about how I could use it to send some more link juice to my site.
Although it definitely is a great vehicle to host spammy pages with the sole purpose of generating backlinks and pass on linkjuice, I think it can also be used for a white-hat approach.
The way to do it right should follow rule #1 of good internet marketers: to create valuable and unique content with useful information that helps people out.
In this specific case, it might be a how-to piece "on how to select the best self storage service" or "5 pitfals to avoid when selecting selfstorage".
The article should be unique (in terms of content, so it is not picked up as duplicate content), **useful **(so that people actually read it and eventually tweet or +1 it) and **authoritative **(using 3rd party references to support what it says). No hard selling pitches, no blatant promotion of products/services... only useful information, with relevant links to different and authoritative domains... and, of course, a couple of good links back to your site.
PS: I haven't tried it... so I don't know if creating such a page would have any impact on a website ranking. What do you guys think? Is it worth spending the time to come up with such a page?
