For example, my home page is available in several language and the language displayed depends on the browser language.
I have added these 2
<link rel="alternate" href="http://example.com/lang/en" hreflang="en"/> <link rel="alternate" href="http://example.com/lang/fr" hreflang="fr"/>
Is it possible to tell search engines that the URL
http://example.com is available both in English and French and the one displayed depends on the browser language?
