I had a bunch of pages that came down with Squidoo, and I recently started restoring them, starting with the highest-traffic ones, making a few small changes and improvements like adding new editions and fixing broken links and improving some of the text.
These were very popular pages, and on Squidoo made a significant number of sales. My #1 one was the calculus reviews one, which has already been up, but I recently published some others. Here they are in order of past popularity:
The calculus one hasn't recovered in traffic, unfortunately. It used to bring in 100-200 visits a month, and it's now creeped up to about 10 visits a month, which is a fraction of its original traffic.
I'd love any feedback or tips about how to restore the prominence of these pages. I'm hoping that getting all of the pages back up (which I plan to have completed soon) will help produce some synergy. I was also thinking of reaching out to some of the authors of the books if they have homepages (most professors who author books do) where they might want to link to the reviews.
