Should fragment identifiers (i.e. #) be included in the parameter handling?

Should fragment identifiers (i.e. #) be included in the parameter handling? efdev 9/23/09 3:26 AM
Does Google consider these two url's to be the same or different when it comes to indexing?
example.com/abc.jsp#search=123
example.com/abc.jsp

If it considers them to be different, can we include fragment identifiers in the parameter handling section of webmaster tools so that they get ignored? I am asking because it seems that you can only ask Google to ignore URL parameters and not fragment identifiers.

Thanks!

Fragments should be ignored anyway.
In most cases, Servers do not pay attention to them - it's the Browser that does..... so it shouldn't be a problem.

I am seeing Google use them more.

See this url:

http://www.google.co.uk/search?q=google+safe+search&pws=0&hl=en&num=10

Google have a "Jump to SafeSearch filtering‎" link, pointing to a fragment, inside the SERPs listing.

Hence I wouldnt remove them unless they made no sense whatsoever.

Part of the issue is that some techs (JS and Flash) use # to identify and process info.
Completely stuffs up the idea of a "fragment" being a destination part of a page (target anchors etc.)

As far as I know - Google will not see it as a duplicate though.
It should be able to identify that it's refering to itself (if on the same page) or part of another URL (if refencing a different page).

Can we please get a definitive answer from Google on this?

Hi efdev
We generally ignore the "fragments" (as in http://domain.com/path#fragment) when crawling, indexing and ranking since this is generally just something that is handled on the client side. There are some cases where we're experimenting with showing them in the snippet (as in Colin's example), to help users to find parts of a page quicker, so if you have large pages, that might be something to consider. You do not need to (& cannot) mention these fragments in Webmaster Tools.

Hope it helps!
John
