Google My Business
How do people find information about your library? I bet you think a lot about what you put on your website, but have you thought about the accuracy of information when people try to look up your library from a mobile device and Google steps in with results?
I find that I often rely on the Google listing for a business, rather than navigating to the business' website and trying to find information there (especially for hours, address, directions, phone number, and reviews).
Google My Business is a free listing service created by Google in 2014, and your library most likely already has a GMB page. It's an excellent idea to 1) claim it if you haven't already, and 2) verify/update the information on it. Information that administrators can add/edit includes library hours, description of your library, map pin/location, URL, phone number, organization type, and photographs. The built-in analytics can give you a good idea of how patrons found the listing, and what actions they took (did they call you? did they click over to your website?).
This Computers In Libraries article, "How to Create a Google My Business Page" covers why and how to take control of your Google My Business page and is definitely worth a read!
