A great way to boost your seo is with a blog page. Write about things that are relevant to what you do.
Another great thing for seo is your domain name. Think about what your target customer might type into the search engine to find the service they need. For instance commericalcleaningcolumbusohio.com would probably be a better that limitlesscleaning.net (although you do have cleaning in your domain so its not too bad).
