As a trades person, you will be trying to target your local geographical area to gain more referrals through your website. There are many SEO implementations that you should have in your website to ensure that you are getting the right sort of traffic from the right location. One of these that will help you rank better is to make sure you implement geo location tagging metadata on every page of your website. This isn't seen by visitors to your website but it is seen by search engines like Google and is used in location based searches.
As an example, you add this piece of code to the <head> section of your website. Change the latitude and Longitude to your own location.
