Find main keywords for Competitors

Hey guys,

I'm wondering if there is a way to find the keywords a website gets most of their traffic from? Moreover, is there a possibility to find which keywords a site ranks highest for?

For my own websites, I can use webmaster tools and google analytics. However, what can be used for competitors?

Thanks a lot

Use Google trends to check for the same.

 

It's hard to get such info. It's too valuable

Maybe I should not say, but I use http://www.seodigger.com

 

You can use Yahoo first to find the backlinks. Then check those sites which keyword they are targeting. Meta keywords and description would give a good hint; if they have them on their site.
