# Endorsement Watch > A famous face is not a study. This page covers how paid endorsements work, why they are persuasive and how to look past them. ## Guides - [Paid Endorsement Disclosure Rules](https://celebrity-endorsement-supplements.hysesulo.workers.dev/paid-endorsement-disclosure-rules/): Paid endorsement disclosure rules generally expect anyone paid or rewarded to promote a product to say so clearly, near the claim and in plain words. - [Deepfake Endorsement Scams on Social Media](https://celebrity-endorsement-supplements.hysesulo.workers.dev/deepfake-endorsement-scams/): Deepfake endorsement scams use altered or invented video and audio to make a celebrity or doctor appear to recommend a supplement they never mentioned. - [Checking an Expert's Credentials Quickly](https://celebrity-endorsement-supplements.hysesulo.workers.dev/expert-credentials-check/): An expert credentials check means confirming that the named person exists, holds a license in a relevant field and is speaking within their expertise. - [Image Search for Testimonial Photos](https://celebrity-endorsement-supplements.hysesulo.workers.dev/image-search-testimonials/): A reverse image search takes about a minute and can show whether a testimonial photo appeared earlier on stock sites, other products or unrelated pages. - [Trust Signals vs Proof](https://celebrity-endorsement-supplements.hysesulo.workers.dev/trust-signals-vs-proof/): Trust signals are things that make a page feel reliable, such as seals, star ratings and calm design, while proof is evidence you can check independently. ## About - [About Endorsement Watch](https://celebrity-endorsement-supplements.hysesulo.workers.dev/about/): not medical advice, how the site is funded and how guides are made ## Optional - [RSS feed](https://celebrity-endorsement-supplements.hysesulo.workers.dev/feed.xml)
