NAP Consistency Checker
NAP means name, address and phone. When your Google listing and your website disagree, customers and search engines get mixed signals. Find your business and we will compare the two.
What this checks, and what it does not
It compares your Google listing with the homepage of your own website. It does not check other directories; those need to be checked at the source. On a paid plan, GravyBlock keeps checking that your details agree across your website, Google and, where connected, Yelp and Facebook, and alerts you when they drift.
