I received following email from Google Webmaster.
Incorrect hreflang implementation on http://gifyu.com/
Google has detected that some pages on your site have implemented the rel-alternate-hreflang tag incorrectly. In particular, there seems to be a problem with incorrect language and region codes, or incorrect bi-directional linking (if page A links with hreflang to page B, there must be a link back from B to A as well). Google uses the hreflang attributes to serve the correct language or regional URL to the right users in search results.
Until you correct the errors on the hreflang links, your website will not benefit from additional language or region targeting.
Could you advise how to resolve this?
