There are dozens of types of authority signals, from testimonials to reviews to social media share counts. The key is identifying which ones make sense to highlight for your products or services, and figuring out the best placement for them.

Your goal is to show people you know what you’re talking about by leveraging third-party validation. Your audience doesn’t just have to take your word for it that you know what you’re doing — other people can confirm that you’re great, too!

I like how SquadCast tackles this. On their homepage they have a few authority signals they provide, including testimonials that match with each user persona, which I think is really smart.
