You can have as many sites as you want according to google, as long as they're in different niches.

I'm about to start 2 legit sites (might expand with more in the future) with my real name as the author behind them.

I obviously want my photo to appear in google search engine for all sites.

I'm confused as to how I am suppose to setup and link my social accounts though?

How would you go abouts doing it?

EDIT: Because while I would want social activity from both sites, seeing that they're in completely different niches it seems weird for me to be talking about both niches on the same social accounts and I'm sure a lot of the subscribers would be turned off by the fact that I'm talking about something completely different from my other site that is totally not related to what they got hold of me on twitter or facebook for example.
