Hi,
Thanks for your fast answer. I still have reviews working on my website, I am just concerned that Google penalizes my ranking because they cannot read the entire content of my pages. And in my Google Console I got a red message saying something like “…if GoogleBot cannot access to some ressources of your page, this page won’t be well indexed”.
Thanks for your help
Julien
Same thing for amazon.com : check their robots.txt file : https://www.amazon.com/robots.txt
They disallow : Disallow: /reviews/iframe
