Network of blogs, separate seo plugins
 

I am planning to work on a network of 200 Wordpress sites. They would be based on Wordpress Multisite. I was wondering, whether it would make sense, to use two separate seo plugins, for better seo results.

I am not talking about two at the same time, on both websites. I would like to install one on the first 100, and the other on the other 100 sites (mix it up too, not just first 100, and the other 100), to make the websites more versatile. 20 different themes would be used too.

Would the same go for a sharing plugin. Would it make some kind of sense to mix it up even further, and use AddThis on 100 sites, and lets say Shareaholic on the other 100?

Thanks.

I don't know if it would make a difference. The only thing you can do is try and see which works better.

Why not just make one big wordpress site instead of multi site on different subdomains.

I don't think google recognizes subdomains as separate sites any more except if it's their sites or their buddies.
