One of the best and easiest ways to what your competition is up to is by looking them up on the search engines. Use the keywords you came up with in your brainstorming session and see what comes up in Google, Yahoo and bing. Google will bold your search terms on the results, but these words are less important than the words that surround them.
Sometimes Google will give you a "Did you mean ___?" phrase to help refine your search. These phrases can help you find the better keywords to use.
Make sure to notice the highest listings and look at the words surrounding your keywords. These phrases and words can make all the difference when attempting to get your page ranked.
Once you have a good idea of some keywords your competition is using, then its time to checkout their websites. Because search engines look at content and keywords together, you will want to find ways to improve on what they are already doing. This is important if you're looking to take that industries traffic and build back-links to your pages. Checking out a sites metadata is also a great way to find the keywords they're using.
To check out your competitors keywords in the metadata right click on the screen and inspect element. In Chrome this is especially easy and worth it. The keywords will be found in the <head></head> section of the code near the top.
