Putting together the data for a local listing in Google is hard work. If you’re not careful, you could be making your work even harder. Duplicate listings in local search are no different to having duplicate page listings. Duplication has one serious down side – it tends to divide the value of links coming in to those pages, or, as is the case with local search, divide reviews and other similar ranking values.
It is not uncommon for a site to rank highly in a local search seven pack, only to see that listing disappear altogether overnight. The reason is normally because a duplicate listing has crept in. So how do you prevent a duplicate listing appearing for your business? According to Search Engine Journal, there is really only one cause for this problem, and that is accuracy.
If your business is listed in other directories, then be sure that every listing has exactly the same information, and that it’s accurate. It only takes one directory to have different information, such as telephone number, business name or address and a duplicate listing could be created.
This is going to be an ongoing problem. You have to be sure your Google business listing is accurate and from that moment forward, every time you list your business somewhere, you will need to ensure the data published is exactly the same as that on Google’s local search. Just another headache for small business owners to think about when optimizing their business listings.
