Even after reading the above article, if one still wonders why they would need Google Map to be integrated in their site, you need to probably spend some more time reading through the rest of the article.
All in all the major benefit of using the Google Map is basically that people can use it to get directions right from the comfort of the home. Businesses can just put in their own address, set a waypoint and the map will tell them how to get there in few seconds.
Google Maps have literally revolutionized the way we look for things and how we can reach it in seconds. One of the most promising and prospective tactics of internet marketing, Google Maps is both beneficial for businesses and customers. Businesses can notify where and how to find them while customers can search and find them in a jiffy. This is the easiest emerging process which is definitely more effective than the age old simple website marketing.
Google maps work best for businesses that are primarily targeting audience within their own demographic location. Now, if Sherlock Holmes is hungry and is craving for pizza he would look up for the Pizza place closest to Baker Street on the Map and have Watson place his order. Now he wouldn’t obviously look for a pizza place near Piccadilly Circus now, would he? Simple reason: it's closest to his location.
Having a Google Map integrated to your site helps your business actually close prospective deals by letting your customers know how close you are to them and how easily he/she can reach you.
