SpyFu
SpyFu is a competitive intelligence tool for search marketing. It allows users to see which keywords competitors are bidding on, how long they have been running ads, and what their ad copy looks like.
For Google Ads advertisers, SpyFu is often used during campaign planning and keyword research phases. It provides historical data that can help identify profitable keyword opportunities and avoid saturated terms.
SpyFu is best suited for marketers who rely heavily on competitor analysis to shape their paid search strategy.
