SEMrush provides users with invaluable competitive intelligence - tracking the top 95 million keywords and 42 million domains. SEMrush data currently includes 10 of the most popular regional Google databases, as well as US Bing, and returns extensive metrics relative to both organic and paid traffic (both AdWords and AdSense), as well as backlink info.

SEMrush can reveal just what keywords your competitors are ranking for, what campaigns they're running, what their budget looks like, and what kind of traffic they generate. Thus, it can provide all the ammo one needs to effectively optimize, run impactful campaigns, and increase overall traffic and revenue.
