A Google citation is the name, address and phone number, sometimes referred to as the “NAP” of your business as google finds it listed on the internet. If you are aiming for top page listings on Google, citations can help you gain a favorable position.
There are hundreds of citation sites out there and the goal is to be on as many as possible. You should always use the same address and phone number and provide as many pictures and information as will possibly fit. There are niche specific citation sites out there. Get on them and go ahead and pay for them if necessary, especially if they give you access to useful data. The more places you can put your business name, address and phone number the better results you will acquire. This process is one of many and a minor, but important, step of the SEO ranking system, that is not to be over looked and under valued.
