I have a German site with Adsense integrated. To meet Google's compliance requirements, I ask users to accept cookies for personal advertising.
To do this, I created an overlay that stays in front of the content of the page (which is blurred in passing). If the user accepts the cookie, the overlay closes and the content is revealed (without blur, of course).
Does this negatively affect the SEO (because of the overlay, which is in front of all the content)
