Your listing is live, congratulations!
It is now time to personalize it by adding your logo, a cover image, visuals related to your products / services and a description of your offer. Do not forget to include your contact information (phone number, email address, opening hours, external links such as your Facebook page).
By inviting your customers to leave you a review as soon as the opportunity arises, you will increase the credibility of your business in the eyes of visitors who do not yet know you.
If this process can seem tedious, it strongly contributes to your local SEO and, therefore, deserves your greatest attention! Keeping your Google+ page up to date is a sure and free way to increase your online visibility. Not doing it would be a serious mistake.
