- LinkedIn has more than 130 million registered users
- Twitter has more than 465 million registered accounts
What do these facts mean? Your insights are as good as and probably better than mine.
What does this have to do with SEO? Good question. Social media in general and cumulative social media (LinkedIn + Facebook + Twitter + whatever) make you and your company more visible online.
In short, it boosts onlline findability, supports SEO (search engine optimization) efforts and generally improves your ranking in SERP (search engine results page) results. For better or worse.
