This is the newest (v. 4.20) release of the BookAdder package. Size does matter. How much it matters is always a debate, but adding well over 100,000 pages can only help, especially when those pages are reasonably relevant to your site, of probable real interest and use to your visitors, frequently changing, absolutely "white-hat", and even potentially profitable. What we have here is a very easy to roll out bookshop, based on Amazon for new books and Abebooks for used books. It uses PHP to dynamically construct pages by interfacing with Amazon's and Abebooks' web database interfaces, and so takes up little actual space on your server. Relevance is assured because you pick the keyword phrase--with the help of an interactive tool that is part of the package--that determines what titles are listed in your shop. The results are attractive and simple for your visitors to navigate and use. Nor are visitors overwhelmed. The actual number of titles listed is typically a little under 4,000; but Amazon has six distinct international divisions, as (effectively) does Abebooks, and each title creates multiple pages in each division (as, for example, by title/author and by ISBN), so that there is a multiplier effect of 30 (five pages apiece in six divisions) turning those 3,500 or so titles into those 105,000 or so pages. Also note that the package sitemaps itself and auto-notifies all three major search-engines (and others can be added with ease) at every update, which can--and should--be easily auto-scheduled for daily. And it neither places nor modifies any files outside its own dedicated subdirectory. (Though you do, of course, have to provide a link to it somewhere on your site.) Do the engines really list all those pages? After some years of running BookAdder on a number of my own sites, my experience is that on average about 53% of the generated pages are included in the site page count as shown on a simple Google "site:" search; the numbers vary, for me, from a low of 19% to a high of 83%, on no pattern I can discern. But even at the very worst, that's tens of thousands of pages. And many of those sites, which--as I say--have been using BookAdder for years--rank rather high for their keywords, some quite competitive. The package installs easily, requiring only that the server have PHP of v. 4.2.0 or better, which any host should have. (BookAdder has been developed and tested extensively on Apache-based Unix servers, but should work on Microsoft-based servers as well.) You can have a basic install up and running in just a few minutes, yet you can also go on to easily customize a huge number of things; the package makes it easy to deploy Google AdSense and/or Digitalpoint Co-Op Network ads (either or both or neither, as you will), and to change colors, type fonts and sizes, and a deal more. The package itself is free. If you are or become an Amazon and/or Abebooks affiliate, commision revenue is automatically split 50-50 between you and me by way of a randomizer applied to every visitor inquiry. The theory is that the possible income is not a major factor (else you'd already have such a shop), and that the SEO and visitor-attraction aspects are your major concern. Still, you should get some cash out of it as well. The home page for BookAdder is at http://seo-toys.com/bookadder-seo-package/ That page includes not only the package download but access to all of the extraordinarily complete and copious documentation for the package, as well as a link to a long-established actual in-use example of the package. I am typically quite responsive to inquiries, and both my email and my office telephone number are included in the package documentation.
