Welcome to the Q&A Forum

We want address the search market for USA and UK. Therefore all english pages have small regional variations with similar content. Since a longer time (after a relaunch) Google has problems to identify the right page (/en-gb/) for the right search market (UK) - although we use hreflang and sitemaps from the beginning. We monitor those in moz for our UK campaign (/en-gb/ pages) by jumps in the ranking of individual keywords (>-50 and >+50). -50 means not that the ranking of our website is lost. In this case Google will substitute the ranking of the /en-gb/ page with the variant /en/. One excample:
https://www.openmind-tech.com/en-gb/industries/cam-software-for-motor-sports/
This page lost the ranking and the other languag variant is ranking for position 2.
https://www.openmind-tech.com/en/industries/cam-software-for-motorsport/ In the moment I have no idea what we can change in our html code.

Hello everyone, We've been migrating every couple months to get everything under Previous migrations went off without a hitch, and hreflang tags were successfully identified. Google claims that it detects no hreflang tags in this new UK migration (completed one month ago). We use hreflang tags in our sitemap and have had no issues so far. What do you think is going on? I greatly value your advice and assistance.
