I am doing some SEO work for a company who supplies surveying equipment, which is quite a niche market. With a very limited number of related websites and blogs to get back links from, as far as I can see, all that is left is general free business directories. Has anyone any other ideas of getting some quality back links?
With surveying equipment I think you could branch out to construction, home building and similar since they are still on topic for that type of equipment.
