Why build social profile ?

Hi, I know this question may sound stupid but I have heard a lot of times that it's good practice to build social profiles (Fb, Twitter, Pinterest...) to make your business look more real in the eyes of Google and get more link diversity.

My question is since some of those links are non-index and don't appear in Google Search Console or software like Ahrefs, do they really help your link profile? Wha is the point in building them?

They will build your brand because if you are active (at least somewhat) on these social networks, you will be discovered by other, new people that are also on that social network, giving you an opportunity to drive traffic to your main website or to convert new leads on that social platform

Yeah, I know that might be the case but since my main focus is SEO, I have only created them for link diversity but now that I have noticed that Google doesn't even consider them as backlinks I'm questioning their utility.

Matt Cutts of Google said so himself:

Facebook and Twitter pages are treated like any other pages in our web index so if something occurs on Twitter or occurs on Facebook and we’re able to crawl it, then we can return that in our search results. But as far as doing special specific work to sort of say “you have this many followers on Twitter or this many likes on Facebook”, to the best of my knowledge we don’t currently have any signals like that in our web search ranking algorithms.

Build social profile is important for discover new guests for website.
