Welcome to the Q&A Forum

As Kate said above competition is different for all keywords. I find ranking for geographically specific keywords fairly easy but when I broarden that only slightly I find it very hard to compete as many more companies are targeting the same thing. The hardest thing in SEO is to identify what your customer puts into the search bar, often this is different to what we would as we are blinded by our own knowledge. Ask a child to find your site using search only and you'll soon see. I hope that helps

very nice and informative article keep up the good work
