I have not built a lens with Squidoo, with that being said, I have noticed very many squidoo lenses with high traffic volumes. I still do not believe that it can match Hubpages for profitability. One thing you can do with Squidoo is advertise some affiliate links. This is pretty tough here at Hubpages. I like Hubpages because if you write well, you have the opportunity to rank high and get traffic.
Ezine articles is really good for writing articles and leaving a link in your author box for affiliate sales. You can get some real decent traffic from this site. I would do this and use Triond for affiliate marketing. I would join Hubpages to learn and to rank high if you write great content articles and continue to do it. You can make money with hubpages ads or adsense.
