Use SEMrush to Boost Your SEO Profits

Competitive research tools can help you find a baseline for what to do & where to enter a market. Before spending a dime on SEO (or even buying a domain name for a project), it is always worth putting in the time to get a quick lay of the land & learn from your existing competitors.

  • Seeing which keywords are most valuable can help you figure out which areas to invest the most in.
  • Seeing where existing competitors are strong can help you find strategies worth emulating. While researching their performance, it may help you find new pockets of opportunities & keyword themes which didn't show up in your initial keyword research.
  • Seeing where competitors are weak can help you build a strategy to differentiate your approach.

Enter a competing URL in the above search box & you will quickly see where your competitors are succeeding, where they are failing & get insights on how to beat them. SEMrush offers:

  • granular data across the global Bing & Google databases, along with over 2-dozen regional localized country-specific Google databases (Argentina, Australia, Belgium, Brazil, Canada, Denmark, Finland, France, Germany, Hungary, Japan, Hong Kong, India, Ireland, Israel, Italy, Mexico, Netherlands, Norway, Poland, Russia, Singapore, Spain, Sweden, Switzerland, Turkey, United Kingdom, United States)
  • search volume & ad bid price estimates by keyword (which, when combined, function as an estimate of keyword value) for over 120,000,000 words
  • keyword data by site or by page across 74,000,000 domain names
  • the ability to look up related keywords
  • the ability to directly compare domains against one another to see relative strength
  • the ability to compare organic search results versus paid search ads to leverage data from one source into the other channel
  • the ability to look up sites which have a similar ranking footprint as an existing competitor to uncover new areas & opportunities
  • historical performance data, which can be helpful in determining if the site has had manual penalties or algorithmic ranking filters applied against it
  • a broad array of new features like tracking video ads, display ads, PLAs, backlinks, etc.
