There’s a great roundup of tools that will help you to work out which keyphrases your competitors are listed in the search engines for here – http://www.searchenginejournal.com/tools-to-find-your-competitors-keyword-rankings/7119/
Please take notice of Amm’s advice:
- do not just copy-paste your competitors’ keywords, use it as additional help for your keyword research;
- compare which keywords your competitors optimized their pages (i.e. tried to rank for) and which keywords they ended up ranking for. Thus you’ll be able to avoid their mistakes.
