I find it crazy that a web technology, java, is built to really screw with crawlers, seo & linking. I have found a number of sites now that use jsessionid in the url. You can see them around in the google index http://www.google.com.au/search?q=inurl:jsessionid

If you want good SEO I suggest you dont use them. You really dont want your URL’s changing with each user/crawler. Here are a couple of reasons:

1. how can you build pagerank if you never have the same url twice? I might like it & backlink to it but noone will ever visit your site & give you a backlink to the same URL.
2. I dont know how google and other search engines manage the issue of duplicate content. Google doesnt seem to normalise the URL and strip jsessionid from the url. So the same page is never thought to be the same page as the address/URL is always changing! I have found the same page in the google index multiple times http://www.google.com.au/search?q=inurl:adobe.com/thread/46030&filter=0 …bad, bad, bad.
3. The urls are l o n g & contain nonsensical strings like F03168B437862EC70280376876C5E1E5 which are not human readable and often break as people try to email or copy and paste etc.

There are other ways to track & store state other than munging the URL with very long session id strings which really hurts your site if you want to be indexed & grow pagerank.

You can leave a response, or trackback from your own site.
