Right click page source, observe page code, both google tag manager and facebook SDK are in there, nothing much to check. Some people do not like this, and I advise using Tor/Onion if you require high level of privacy. Personally, I don't care all that much, because my telecommunication provider has no idea where we are, so my geotag is off by a huge margin.
Both things sdk and tag are used for tracking, quality improvements and overall how search treats a website. Any apk hosted on either Apple and Shop, webpage hosting, domain etc, has some sort of an analytics, but number of downloads and views is not the same like having Metastasis banged on a front page.
There are plethora of reasons to get rid of Metastasis and Snoople, I hope they will drop it, neither of these things provide either trustworthiness or solid page traffic analytics.
Yakihonne expects sponsors and growth, that can be a motive to install analytics and tracking.
Problem is that this is a long post client wrapped in a webpage, so search just sees an empty husk.
Mapping URLs with something else than a long code may help, for example in case of Habla, there is a naddr URL and classic.
Using tag and sdk can help in social sharing. Bloggers like to cross-post and share their work, but with a current social media situation I sincerely don't know where to without being banned for shilling, so I think that Nostr environment should come first. A fact is that we can blog from a command line on nostr relay with NIP-22, maybe a focus should be on author feedback, mobile app and visual satisfaction then on an inflow of external communities.
