OK, 2 primary questions for a multilingual site. This specific site has 2 language so I'll use that for the examples. 1 - Self-Referencing Hreflang Tag Necessary? The first is regarding the correct implementation of hreflang, and whether or not I should have a self-referencing hreflang tag. In other words, if I am looking at the source code for http://www.example.com/es/ (our Spanish subfolder), I am uncertain whether the source code should contain the second line below: Obviously the Spanish version should reference the English version, but does it need to reference itself? I have seen both versions implemented, with seemingly good results, but I want to know the best practice if it exists. 2 - Canonical of Current Language or Default Language? The second questions is regarding which canonical to use on the secondary language pages. I am aware of the update to the Google Webmaster Guidelines recently that state not to use canonical, but they say not to do it because everyone was messing it up, not because it shouldn't be done. So, in other words, if I am looking at the source code for http://www.example.com/es/ (our Spanish subfolder), which of the two following canonicals is correct? OR For this question, you can assume that (A) the English version of the site is our default and (B) the content is identical. Thanks guys, feel free to ask any qualifiers you think are relevant.
