In My site I have used rel="alternate"
for RSS as follows
<link rel="alternate" type="application/rss+xml" title="RSS 2.0" href="http://www.mydomain.com/rss" />
Now I want to add another rel="alternate"
tag for the mobile site as
<link rel="alternate" media="handheld" href="http://m.mydomain.com" />
Is there any issue to use multiple rel="alternate"
tags in a page or no any effect to the SEO?
It's no problem, quite the contrary, it's even encouraged.
E.g. to link to several translations of a page; see the example in HTML 4.01: Links and search engines. Or to link to several different feeds; see the example in HTML5: Link type "alternate
". Or to link to several different (= alternative) stylesheets.
