The "magic" in getting your squidoo lens ranked high is based on:
1. the lens url, i.e. squidoo.com/your-keyword
2. how the keyword is used throught the lens, i.e. the title should have the keyword <h1> tag, the introduction should have the keyword at least twice, even in <b> & <i> tags
3. you should use at least 4 content modules
4. i think may be optional, but I always ping my lens in pingomatic and sometimes its spidered by google if not immediately, then max 24hrs
One of my lenses is ranked number one in both google & yahoo for a click*bank product. I'd say do a search for your keyword and see which lenses are ranked highest and pay homage by following and improving upon their success.
Hope this helps!
