Parameter details:-

Google MAP APIs to charge for usage, heavy traffic cost more

Google MAP server with their increased traffic has given a new dimension of earning to Google. With its success now Google is planning to charge for its usage.
Now one has to pay according to their usage.

Following is the cost estimation as per BBC
"The BBC is reporting that from 1 January 2012, Google will charge for the Google Maps API service when more than the limit of 25,000 map "hits" are made in a day. Google is rumoured to be charging $4 per 1,000 views in excess of the limit. Google maintains the high limit of 25,000 free hits before charging 'will only affect 0.35% of users.'"


In the Google announcement: "We understand that the introduction of these limits may be concerning. However with the continued growth in adoption of the Maps API we need to secure its long term future by ensuring that even when used by the highest volume for-profit sites, the service remains viable. By introducing these limits we are ensuring that Google can continue to offer the Maps API for free to the vast majority of developers for many years to come."

About Google Maps API

The Maps API is a free service, available for any web site that is free to consumers. Please see the terms of service for more information.
Businesses that charge fees for access, track assets or build internal applications must use Google Maps API Premier, which provides enhanced features, technical support and a service-level agreement.
