What SEMrush is
SEMrush is the Swiss Army knife of digital marketing, offering all the data needed for SEO, PPC, content marketing, and competitor analysis in one platform. With a database of over 25 billion keywords and 800 million domains, it allows you to see exactly which keywords your competitors are ranking for, how much they spend on ads, and their content strategies. From 'Site Audit' to 'Keyword Magic Tool,' it provides the strategic data required to dominate the search engine result pages.
What SpyFu is
SpyFu shows which keywords competitors bid on and rank for, with historical data going back years. That archive is the reason to use it: rather than a snapshot of today's rankings, you can see how long a competitor has defended a term, which ad copy they kept running, and which campaigns they abandoned. Coverage is strongest for the US market and thinner elsewhere, and the data is modelled rather than taken from ad accounts, so treat the figures as direction rather than measurement.
