Use long-tail keyword phrases in your title.

First, you need to do search engine keyword research, which is a lot easier than you’re probably thinking. Here’s a Keyword Research Tutorial to get you started.
If you’ve ever wondered what your target readers are interested in, you can get a behind the scenes look at what they’re typing into Google by doing some simple keyword research.
The long-tail keyword phrases are the longer,  less popular and therefore less competitive phrases. The fact that they’re less competitive means that with a little effort you can dominate the search engines for these phrases. By consistently writing articles targeting long-tail keyword phrases, you could eventually create blanket coverage for niche.
Long-tail keyword phrases are usually super specific and can be easily adapted to be an article title. Think about the long-tail keyword phrase “how much does it cost to rewire a house”. This would be a perfect one for an electrician, as the phrase is a title in itself–all it needs is for someone to write an article to answer that question.
Compare that to the keyword phrase  ”commercial electrician”, and not only do you have stiffer competition with the shorter, more general phrase, but you also don’t have as much direction for subject matter for the article.
