How The Google Compatibility Calculator Works

Enter your name and the name of the person you want to be matched with into the appropriate boxes in the calculator, then click “Calculate Our Compatibility”. A client-side JavaScript uses AJAX to query Google for the number of search results that come up for each name at Google. It then uses those numbers to determine a compatibility score.

Please note the calculator doesn’t work properly, since Google changed the API.

INSTALLATION

Download popucalc.zip. In it you will find the three graphics, PHP script for querying Google via their RESTful search API, an HTML file with the AJAX JavaScript and the search form, plus a README file with further instructions on getting it running.

Here are the two source files if you’d like to examine them.
