Ask HN: Is it good to bring social content on company blog?

I was wondering how it can be useful for startups blog? Since startups use a various social media platform to reach users. Most of them use Twitter, Instagram, Facebook, Medium kind of platform. Bringing contents from all these platforms to the blog can help them to SEO and give more information about the company. Need HN users Thoughts...

PS: I am working upon social content aggregation.
