i have set up 1 squeeze page which offer free software to capture their email. does this kind of squeeze suitable for social bookmarking like digg? what else of other traffic suitable for this site? thanks.
By looking at this link I don't really understand what it is that I am getting for my email address. I think you should write something about what these 3 software pieces are that you are offering.
Your link is a sales page not a squeeze page as it asks for money. You would need to create another squeeze page where you could offer a free gift or a chapter of your product with another link to the sales page in the gift or follow up email or as an up-sell in your sales funnel. You could include social bookmark tags on this page. WordPress would be the easiest way to do this. It could double as a blog site as well but only direct them to this in your follow up emails - not from your squeeze page. You want this to have one function only.
