You surely have to start by creating a profile on Google My Business (GMB) before you implement any strategy. To set up your business, go to GMB page while signing in to Google account. Make the list and fill in all the important information about your business. Make sure you know about all Google guidelines before you create your profile. Once verification is done, everything is set up.
Now it's time to implement ranking strategies, such as inviting more and more reviews, add photos to your listing, input as much information as possible about business and update it regularly, optimize your website with relevant keywords, and more.
