So, it wasn't the problem I thought it might have been. So your page urls don't automatically append the session id to the end? I might have the wrong variable name so if you're still seeing them, I obviously have it wrong... No, you're right and my url's are clean of SID's -- they always have been, that was the default. The problem I was trying to figure out was how the use of SID's cause SE's to fail and how that works. I figured that once I understand how that worked, then I could keep from doing it. I just needed to see for myself what it was. You know, one of my wonder why this works studies. While the problem wasn't present for me, which at the start of this I wasn't sure about, I did learn how it works and why SE's have problems with indexing url's that have ? in them. For those interested in this thread, this is what I believe is happening. If you have a web page that uses SID's in it's url, then it appears to a SE as something like this (using one of my sites as an example): http://ancientstones.com?PHPSESSID=1234 and not like: http://ancientstones.com/ So the SE grabs the page with the SID. The next time it travels your site, it see's: http://ancientstones.com?PHPSESSID=5678 and grabs that page. After a while, Google has numerous duplicate pages and has to pick one to be representative of your site and store all the others into it's supplemental index. Now when Google determines PageRank for your site, it does so by calculating how many sites link to your site (simple version). If Google has picked: http://ancientstones.com?PHPSESSID=5678 to be THE representative for your site, then you're sunk because no one uses a SID in their link to your site. Your site will always have a PR of 0 -- as it is with the referenced site. While the site ranks very high (currently #1) in a Google search for Custom Tile Medallions, it has a PR of 0. I was trying to figure out what was happening and if there was something I was doing in using php caused the low PR. I found that PHP wasn't the problem -- and now I know that. At least, that's the way I understand what's going on -- if I'm mistaken, please correct me. tedd -- http://sperling.com http://ancientstones.com http://earthstones.com -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] php sessions and Google
Hi gang: I've read that php sessions can create problems for Google bots. For example, the following was taken from a Google Web Master Help Center: -- Quote -- Allow search bots to crawl your sites without session IDs or arguments that track their path through the site. These techniques are useful for tracking individual user behavior, but the access pattern of bots is entirely different. Using these techniques may result in incomplete indexing of your site, as bots may not be able to eliminate URLs that look different but actually point to the same page. -- Un-quote -- http://www.google.com/support/webmasters/bin/answer.py?answer=35770 I've also seen a comment here: http://www.weberdev.com/get_example-3431.html But, I'm not following what's happening. Can someone shed some light on this for me? How can one do sessions and make Google bots happy? Thanks in advance for any comments or suggestions. tedd -- http://sperling.com http://ancientstones.com http://earthstones.com -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

How can one do sessions and make Google bots happy? use_trans_sid (I think) will append the sessionid to all pages, so instead of: /page.php it will become /page.php?PHPSESSID=x much the same as if you do: ?php echo '/page.php?' . SID; ? Bots don't like that, so where possible turn use_trans_sid off (check manual about when/how you can do this). -- Postgresql php tutorials http://www.designmagick.com/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
