Hi again,
I got some interesting news on thread from yoast which have figured out that there are 2 title tags found in source code and this may harm the google approach. Find here the info’s they found in this thread.
We have inspected the source of this page and noticed that there are 2 title tags: https://i.imgur.com/T62o4nT.png
It seems to be an issue on all your pages, you have 2 titles tags. One of them is not generated by Yoast SEO, it would be best to find out which plugin (or your theme) is doing this and remove the extra title tag.
Regarding the titles shown in Google being different than the ones you have set, we have inspected the URLs which you have provided and noticed that the title tags match what you have set in Yoast SEO.
If you have recently made these changes, it is possible that Google has not updated its index and is still showing an outdated title. In this case, we recommend waiting up to 2 weeks then check again if the titles have been updated.
If the changes are not recent, then it means that Google has decided to ignore your title and replace it with a different one. Unfortunately, in this case, there’s not much you can do other than try again with a new title, hopefully Google will consider the next one better suited.
As a comparison, Bing seems to have indexed your URL with the correct title. That being said, search engines are getting the correct meta data (such as titles) from your website, but it’s up to them if they want to use that or replace it with something else.
Can you please help me to find out why I have 2 title tags in source code and if those are maybe caused by our GD child theme in use?
