SpyFu is an awesome tool which will show you some great details about a particular set of keywords. I use SpyFu when picking a niche website topic, or when I am trying to figure out what types of competition I will face if I create a website about a specific topic. SpyFu does have a monthly subscription cost for the full features, but the free version can be accessed by visiting the website, providing limited results, but just enough to get a good understanding on wether or not the niche you are thinking about will be profitable. Here’s what Spyfu will tell you when you search for a set of keywords, in a nutshell:
- What the average CPC (Cost per click) of a keyword is
- How many advertisers are currently advertising using that keyword
- The ranking difficulty for the keyword
- What keywords are worthless and should be avoided
