"This site allows Google Analytics to follow you across the internet."

I tested mangadex.org on this handy privacy inspection website: https://themarkup.org/blacklight?url=mangadex.org

I got this result:

This site allows Google Analytics to follow you across the internet.

This site uses Google Analytics and seems to use its ”remarketing audiences” feature that enables user tracking for targeted advertising across the internet. This feature allows a website to build custom audiences based on how a user interacts with this particular site and then follow those users across the internet and target them with advertising on other sites using Google Ads and Display & Video 360. A Google spokesperson told The Markup that site operators are supposed to inform visitors when data collected with this feature is used to connect this browsing data with someone’s real-world identity. You know when those shoes you were looking at follow you around the internet? This is one of the trackers leading to that. This feature appeared in fifty percent of popular websites when we scanned them in September 2020.

Looks like you can disable this: https://support.google.com/analytics/answer/9626162?hl=en

I think you should consider disabling this, is it really needed for your analytics?

Also thanks for this:

2 Ad trackers found on this site. This is less than half the average of seven that we found on popular sites.
