>Here is an interesting thing. Most of the Web sites today, dynamic or not, contain URL references which are static. Thus, Google and all other search engines have their robots which will visit you occasionnaly to index your pages. I have found that if your URL references, for dynamic Web sites, are generated by the use of one encrypted session, that they will keep indexing your page on an ongoing basis. Because, basically, the same page always contains a different URL on every hit. So, for them, their robots keep visiting you and will index the pages because they think those are pages which haven't been indexed before. Basically, it would be as if your page will be updated every day but it is not as only the URL is changing.

>Based on my log, these robots visit you several times a day, such as 3 or 4 times. For every time, they will index about 5 to 20 pages. So, I was wondering if this approach of URL session encrypted generation makes it better for those search engines in such circumstances. Basically, are we in a better shape, as far as being indexed on those search engines, because of that?

>Interesting point, isn't it?

I think that you are in worse shape concerning the rank of the page because each URL is brand new and has no previous click throughs and no external link references. Your page will show up 100's of times but always on page 25 of the search results.
