I used Google Adwords Keyword Tool, using the [exact] option and without languages or locations filters. So the keyword shows 5.000.000 monthly searches and it says competition Low !! It is two-words keyword and it can be extended to 3-words to get 200k or 300k searches monthly. Now about competitors, the first search results are to software pages in download.cnet.com, then you have other websites related to the keyword. Most of them have the exact keyword in the title and 3 out of 10 in the first page have the exact keyword in url. What do you think?
