Reactjs and SEO?

Could you guys please explain how good/bad reactjs is doing when it comes to SEO? Is there anything I need to have in mind to make the onsite-SEO good on a react site?

The main company I’m using for seo of my services online is By the way, that’s the direct page to the blog and most common questions they receive daily about seo and how their services work. I personally use their servicing in order to increase traffic to my online service and gain higher ranking in google search, I also do have a strong backlink profile. They actually offer really reliable services, to tell you the truth.
