I have a well developed lens but it refers very few people to my main site. How valuable can a good lens really be? Does anyone get substantial traffic? Please take a look at mine. I'd appreciate ratings and/or comments on how to improve it. http://www.squidoo.com/obsession-fitness Thanks.
The traffic I get from Squidoo ain't that good either. It depends on the niche and the number of competitors of course. Still it's nice to get a few backlinks and some visitors, just don't waste too much time creating lenses
I use such services (Squidoo and Hubpages) to build links rather than to gain traffic. With this in mind, I build my lens or hubs and move on without thinking of ratings and reviews that I will get.
You'll probably get some value from the link itself, which may help your main site rank in the search engines.
