There's something for everyone to takeaway from this talk, from those starting out in their careers to vets working on mega sites.


Hreflang is often a complicated aspect of international SEO, and since the Hreflang tool was deprecated from Google Search Console it's become even harder.

A couple of years ago, we analyzed Hreflang networks across 18,000 websites to identify common errors and trends to really understand how scaled issues are - this time, we've looked at 1,954,896 websites with Hreflang implemented to really understand how brands globally are targeting different markets, trends, and how to resolve these issues.
