Clickbank Product Not Selling - Options?

Hi,

I have a Clickbank product that just won't sell. I have traffic coming from SEO, referred sites and PPC.

I was thinking of using some alternative options instead of going for the traditional sale;

1) Give the product away for free and collect emails.

2) Give the product away for a "tweet".

3) Give product away in exchange for filled in survey (Content blocker etc.)

Any other options? Or is it best to keep trying to sell the product for $ and trying to find a better angle?

Try to collect email address, so you can monetize it well.

You need a complete Affiliate Tools page.

Okay, going to have one last marketing push with POF. If that doesn't work, i'll just set-up an email sales funnel with the eBook for free.
