It's important that you keep this up to date, as part of your Google My Business presence.
You may have activated your Google Maps presence a long time ago and therefore may need to review the accuracy, as well as optimise your whole Google My Business account (as it's now known, formerly Google+).
Firstly, gain access to, or set up, your Google My Business profile and verify ownership. This is done with a simple walk through - start here.
View the full walk through process in a blog post shared by my colleague, Why You Need a Google My Business Listing.
Once you've given various details regarding your business, its services and location, you can then confirm you'd like to receive the verification postcard from Google, which includes a code you use to confirm your business' location. This usually takes less than two weeks to arrive.
Now that you're set up and verified, make sure you focus on the following:
Make sure you've completed the basics of your profile, including your business location and public-facing contact details.
Let people know when you're open! Fill in the opening hours, including the feature allowing you to add special hours for particular days, i.e. bank holidays and the festive period.
Spend time exploring all of the options that Google My Business offers including choosing your business categories.
Build your presence with posts, which you can schedule using most social media management platforms, sharing images and building your reviews.
Earlier this year, Google My Business launched new post types, allowing you to share 'offers' and specific 'product' posts, as well as 'what's new' and 'event' posts.
