In order to get people to your web site you need to know first who you want to target. Think of it this way, if you’re a construction company located in Phoenix, Arizona and your clients are all Phoenix Metro based, and then you want to target the Phoenix area. Your SEOcampaign should then be focused on keywords like “Phoenix Construction Company” and not just “Construction Company”.
So what should you do first? First look at your current cliental, second determine is the region or regions of your client tell. Finally look at what you want to target as far as cliental type and location.
The moral of the story, to build an effective SEOcampaign takes doing your research and homework!
