As of August 02, 2012, I already received 82.43 dollars from them. I started being a lensmaster (their term for writer) last May 18, 2011. I enjoyed writing lenses (or articles) and currently I have 47 hanging on my belt.
Writing and earning are two different things but they are connected once you master the secrets in marketing. You must write about your passion, things you're interested in and stuff you want to share. If your works received a high traffic and they ranked consistently in Squidoo tier (their ranking system), expect for high payouts.
Google loves Squidoo so your articles will get a greater chance being found on page 1 of Google result. Another thing that is deserving to add here is you can be an affiliate marketer. The site encourages its writers to promote and market their recommended stuff as long as you don't spam your articles with less content and more Amazon, eBay and ClickBank products.
Now you know that your ways of earning money there is not limited to just getting more pageviews on your articles but a complete package for those who want to take it seriously.
