Is it possible to make money on Squidoo without being social? Experienced Internet marketers do it all the time. I have seen 1st and 2nd Tier lenses that hadn't been updated in 1-2 years bring in enough Google traffic to keep them at their high-ranking positions. The lensmasters are often busy working on other projects and no longer active in Squidoo community.
But if you are just starting out on Squidoo, I strongly suggest that you do spend some time reading and commenting on other Lensmasters' lenses and participating in Squidoo forum (Squidu). You are guaranteed to meet some great people who will make suggestions on how to improve your lenses, give you advice on how to bring in more traffic, and squidlike some of your Squidoo creations. I believe that traffic and clickouts are the two most important stats when it comes to lens rankings. However, if you are a newbie, Squidoo internal traffic, Squidlikes, and Squidoo Angel blessings can make the difference between Tier 3 and Tier 4 lenses (making a few cents and realising the potential of Squidoo and not making money at all).
There are quite a few Lensmasters that supported me in many ways and gave me advice when I first started out. Tipi, LisaAuch, Darcie, Liz, TeamSTM, AJ, and many other Squidoo Lensmasters supported my lenses by Squidliking, commenting, blessing, bookmarking my lenses, sharing them on Twitter and Facebook, and giving me advice.
If you are a Squidoo newbie and are looking for ways to increase traffic to your lenses, I strongly suggest that you become an active part of Squidoo community. You will get a lot in return.
