Anyone know of an SEO and SEM tool that can be embedded into an account on a website.

Hey everyone, I was wondering if anyone knew of a SEO and SEM and social media tool that can be embedded into a separate website. I am currently in the process of redesigning my website and introducing an app to go along with it. I currently use agency analytics for clients to see what is going on however I was wondering if there was an alternative solution that I could put onto my website and connect to a an individuals account so I can offer an all in one solution to pay, see activity, and results all in spot.

Does anyone know of something like this?
