Who does know what is the best file extension for RSS feed on the site (for SEO):

1. (XML) mysite.com/rss.xml
2. (RSS) mysite.com/rss.rss
3. (HTML) mysite.com/rss.html
4. (ASPX, PHP, etc) mysite.com/rss.aspx
5. (with url params) mysite.com/rss.aspx?param1=val1&param2=val2
6. some other

I'm going to use (3) html on my site, is it ok?

Thanks.

The file extension shouldn't matter. In theory, the content of URLs is determined solely by the Content-Type HTTP header. In practice, Internet Explorer means that isn't always entirely true.

Personally, I would try to aim for something along the lines of "/feed/ and leave any mention of technology as far out of it as possible.

Failing that, just don't go for something misleading.

So, in reverse order of preference:

An RSS feed isn't an HTML document, so of all those choices, the only one you should actively avoid is .html

Using a server side technology in the URLs ties you (to some extent) to that technology. So the next ones to avoid are 4 and 5 since they mention ASP.NET.

That leaves 1 & 2, which are both fine, and the best explicit choices in that list.

As mentioned above, I'd go with 6 and /feed

I always use .XML and have had no problems.
