I’ve really been pushing Squidoo recently updating old lens and creating new ones, there is so much to learn. It’s important to carefully select any Amazon products that you may advertise, it’s important to advertise just a few so that people don’t get product weary (say 3 items), I know have 3 or 4 Amazon modules interspersed between factual modules. Every time you look at a lens you can see ways of improving it. It’s important to make frequent changes to your lens as well. I use many of the useful tools at http://squidutils.com/ to ping and check backlinks.
By TLC I mean when creating websites making sure that you position Adsense carefully with a transparent background color, that you hyperlink every useful phrase with your affiliate link, eg to Amazon or Clickbank, it’s a numbers game.
