Here is an example: I have an Affordable Search Engine Optimization blog - that's the name of the blog - at http://SmallBusinessClicks.biz. It is for Small Business owners interested to learn SEO.
I published an article written by Dan Kennedy about Unique Selling Proposition. It matters for Small Business owners. I had no intention to rank for keyword 'dan kennedy'.
I found out that the keyword 'dan kennedy' is low competition. It attracts significant amount of web surfers to my blog. Once people get to my blog, they look around and see that the blog is worth their attention. Once people see value, they come back, subscribe and comment.
My advice: do not shy away from low competition and low cost keywords.
If YOU want to use keywords for Pay-Per-Click advertising, YOU will have to optimize the campaign anyway. PPC campaign will not start with the best prices. The website has to have very good search engine optimization to get good quality score and better PPC rates.
