Your business name, address, and phone number must be cited consistently and uniformly across all online platforms, including web and social media and directories (such as Yelp). If your address displays differently, Google will not log it nor display your information in the local listings on search engine result pages (SERPs).
Even if you’re not a restaurant, you should still check online directories like Yelp, claim your business and make sure your address and phone numbers are consistent. It’s easy to check, just search your business name to see how it is displayed in the SERP. If you have an abbreviation like us, i.e. Pacific Software Publishing, Pacific Software Publishing, Inc. and PSPinc, check all of them on search engines. If your business name doesn’t show up in the SERP, you need to start investigating why not. Maybe it's because you never put your address on your website homepage, or Facebook, or Yelp.
Google and other search engines do their best to show the most reliable results, but it all starts with us business owners.
If you put yourself in the consumers’ shoes, would you feel safe purchasing online from a lesser-known or smaller business that doesn’t list their location – even if their website looks great? Personally, I would like to know where the business is located even if I’m getting a great deal on their site. It makes me feel more secure knowing I can contact the company headquarters and it adds legitimacy behind their brand.
So, the moral of the story is your online contact information is important for your local SEO, but also for your business etiquette.
