What is the impact of multilingual versions of Contao pages on SEO? Do the web crawlers see two pages with the same content but different language as two different web pages? I suppose they do, so is it neccessary or recommendable to tag one of them as canonical page of original version (fallback page)?
On other hand I can see something like this in Page Source
Code:
<link rel="alternate" hreflang="en" lang="en" href="index.php/en/page" title="Page title">
<link rel="alternate" hreflang="sr" lang="sr" href="index.php/sr/page" title="Page title">
so is it possible that Contao already gives a proper information to search robots?
