Just a quick tip for those of you that are building XML sitemaps for your web sites. You can now add a line to your robots.txt file to include a pointer to your sitemap file, it would look like this:


This will allow your sitemap to be picked up by several search engines automatically. I first noticed this about a month ago, not sure how long this feature has been around.

What about compatibility? IIRC, unless the RFC has changed, only User-Agent: and Disallow: are expected. And although Allow: is supposedly supported by Googlebot, even Google's robots.txt validator tells me it not to put it (?!).
Where should Sitemap: be? At the beginning? End? Anywhere?
I figure it's best to put it in a meta tag of the root index page, honestly.

Keilaron, the robots.txt RFC allows for "extensions":

extension = token : *space value [comment] CRLF

Indeed, I stand corrected - and in fact, I see that Allow is even in the RFC as well. How odd - Just about every reference I've seen out there only mentions Disallow. Thanks for the info!
