I have often wondered how certain keywords are incorporated into an article when you are building a quality website. For instance, you do your keyword research and find a great keyword with all the stats you're looking for, but the keyword phrase isn't grammatically correct. Take for example the following random keyword 'foot pain heel'. This keyword can't be used if you want a quality article that reads right, but you just have to use it because it has tons of searches and little competition. What do you do in cases like this?
