Other than the obvious ways of promotion like business stationery and adverts, one method that is effective, particularly when looking for local visitors, is to create a business profile.
Basically I write a summary of your business focusing on the key aspects of what you offer. I work to make this profile interesting and informative launching it on my site to link to yours.
My aim is to obtain an ethically achieved high search engine listing for the profile for given search phrases and keywords. The profile is a standalone business brochure from which the visitor can come direct to you. However, because of the links to your website pages on the profile, they are more likely to click-through to explore your pages.
If you think this might be for you, please contact me and we can talk it through.
