Implementing Google Maps into your website is an easy way to provide rich, interactive map features that can help your customers find your business.
Of particular interest to brick-and-mortar stores, Google Maps provides an Application Programming Interface (API) that makes it easy for developers to incorporate custom maps into websites they create.
The first step in working with the Google Maps API is to sign up for what is called an API key. Each website that contains Google maps requires its own API key — an effort to reduce spam and abuse of the service. Once you have your API key, you’re ready to go.
Now that you have your API key, you will need coordinates that tell the API where the center of your map should be. The process of converting addresses to geographic coordinates (latitude and longitude) is called geocoding. Google Maps provides access to geocoders that can easily convert the address you want to serve as the center of your map (such as your business) into latitude and longitude coordinates. With that information, you have everything you need to render a map on a web page.
Rendering maps requires that you add a link to the Google Maps API in the head section of your HTML document. This link is where you provide your unique API key for the site with which you are working. From there, you simply specify an empty DIV element on your page where you would like the map to appear. The API automatically displays and scales the map interface to your DIV element.
Developers can explore many other possibilities with the Google Maps API, and I encourage people to refer to the documentation provided by Google. If your business has a physical location that customers need to be able to find, there is really no excuse for them not to easily find that information on your website.
