Citations are business listings that include the business name, address and phone number (often abbreviated to NAP). They also include a link to the web site and when done well can be very good links for a local business as they greatly help the local and map rankings in Google as they use the data to confirm the address and phone details of the business. They have to be done very well though and most providers simply don't, mine of are a much better quality as they all have unique and high quality content and they are also indexed using the best indexing tool. So they will get into Google and stay in Google as they are such a high quality, so this means that your web site will receive huge benefit in local rankings from them and they can even rank for your keywords which makes them extremely good links as if Google have them in the top 100 for your keyword then they are going to see those as extremely relevant links and they are also from domains with a very high domain authority. I can do lots of these so the minimum is 40 for $25 but then if you would like more I can provide more and am also happy to check how many you currently have to give an idea of how many I could provide. I never create duplicate listings as I always check the existing listings before building the local citations so you don't have to worry about duplicate citations. Then if you really want to take these to the next level I can even build links to the citations so that they have even more power to pass in those links, so this is a good option if you are in a competitive market.
