Perhaps. There's some interesting commentary on that at WebmasterWorld http://www.webmasterworld.com/fo...rum30/ 29793.htm

I have never seen a site use "&id=" and those that use "id=" are uneffected.

Hi John. The comment is from GoogleGuy and is in reference to dynamic urls.

Google and all search engine spidering programs need to be able to crawl urls quickly and efficiently as possible. The "&id=" parameter is characteristic of urls that use session ids, which can cause problems for a search engine spider.

A session id is appended to a url based on a single visit. That creates the opportunity for the same web page to have an infinite number of unique urls. The advice is not to use "&id=" and find another way to track session specific data, like with a cookie.

Head on over to webmasterworld.com or any of the other SEO forums and you'll learn a lot more about the technical side to search engine optimization.

Hey, you've given me an idea for another post on allbusiness.com!

Lee,

Could you expand on this thought in your post?

"I've been aching for a long time to mention somewhere official that sites shouldn't use "&id=" as a parameter if they want maximal Googlebot crawlage"
