Top method for identifying genuine users and preventing bots

Utilizing a Maps API can be costly, especially with the fees per request

  • To minimize requests, I heavily rely on caching techniques
  • The API is invoked on every pageload, but unnecessary for non-human users like googlebot

What would be the most effective approach to differentiate between human users and bots?

  • Avoiding captcha methods
  • Possibly monitoring mouse events during pageload and displaying a loading icon while analyzing (any technical suggestions on how to implement this)?
  • Are there better solutions available?

Answer №1

To display the map image, I recommend utilizing Javascript. Web scrapers and bots usually avoid processing or running Javascript code, which means that your API request will only be triggered when a user accesses the page.

One effective way to implement this is by separating your API call into a standalone webpage that can be invoked through AJAX.

Answer №2

Create a custom JavaScript function such as initialize() to set up your Google Maps API request.

For example:

<script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=set_to_true_or_false"></script>
<script type="text/javascript">
  function initialize() {
    var latlng = new google.maps.LatLng(-34.397, 150.644);
    var myOptions = {
      zoom: 8,
      center: latlng,
      mapTypeId: google.maps.MapTypeId.ROADMAP
    };
    var map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
  }

</script>
</head>
<body onload="initialize()">
  <div id="map_canvas" style="width:100%; height:100%"></div>
</body>
