The "Freebie" SEO package has had another significant update: current users are urgently advised to install the newly released v. 2.42. This version accomodates Amazon file-format changes to restore reader and editorial reviews to the per-book pages. That is important for SEO purposes, as the presence of those reviews, in full, sharply distinguishes this packages pages from other Amazon-derived book pages around the web. If you are not a current user, "Freebie" is a free SEO package that might make you a little money besides enhancing your site. With only a modest one-time installation effort, it tags many thousands of pages (an average of over 20,000 each are already indexed on my own sites) onto any site--and those pages are reasonably relevant (you pick the search theme for the list), constantly changing (every day) pages. They are book data from Amazon, and you can even make some sales money, too. And the package now even makes and auto-updates Google sitemaps. For full information, visit Freebie page of the SEO Toys site.
I'm not sure I understand the question. Yes, the "Freebie" package is of my making. I use it myself on seven or eight (I forget) sites, and more than two hundred other sites have at least tried it at one time or another. The package sits in a subdirectory of its own, separate from your main site content. You select a search phrase keyed to your site's contents; there is a script that makes it easy for you to interactively estimate how many titles a given search phrase will likely return, and advice on optimizing that number for SEO purposes. Once set up, the package goes out once a day (or whatever you set it for) and queries Amazon for titles, using your search phrase; it then filters the returned titles to eliminate books not actually available new from Amazon (which cuts about 70% off!), then arranges the results as 28 separate files (the alphabet, non-alpha, and one more) which are shtml drop-ins for a "holder" file. It also generates a Google-formatted sitemap of the titles, including both the Amazon listing and two corresponding Abebooks listings (three site pages for you) for every title, and notifies Amazon that your sitemaps have been updated. (This can work in parallel with any sitemapping you do on your own.) Each individual listing is a link to a separate page for that title, which page includes *all* (not just a few) of the available Amazon reader and editorial reviews--something that sharply distinguishes those pages' contents from each other and from other Amazon-derived listings around the web. There are also, for each title, two pages of Abebooks-related data--so you get three site pages for each title. It does all that for each of the six Amazon national divisions. At present, my own sites show on average well over 20,000 indexed pages each from the package, and many more--Abe pages newly made by the last package upgrade--are still pending indexing. So you have thousands of pages, each more or less relevant to your site's theme, each changing daily, all sitemapped, with no efffort on your part past the initial setup. (And, as almost all those pages are php-generated, you don't have thousands of large files cluttering up your storage space.) The package comes with exhaustive documentation that explains all that and more.
The package has now moved to v. 2.43. (The 2.42 release was only minor, nonfunctional changes in the docfiles.) This newest upgrade fixes a reported incompatibility with PHP 5.x, and also an obscure problem with getting book reviews from the Amazon Japan division (it affected books released in the UK but not in the US). The upgrade is very simple for users already up to the 2.4x level: just upload the new files over the old.
