Google trends is a service which allow you to track the popularity of specific keywords. Here’s the code to create a WordPress shortcode that will embed a Google trends graph of any comma separated query on your blog.

The first step is to create the shortcode. To do so, open your functions.php file and paste the code below in it:

function wps_trend($atts){
        extract( shortcode_atts( array(
                'w' => '500',           // width
                'h' => '330',           // height
                'q' => '',              // query
                'geo' => 'US',          // geolocation
        ), $atts ) );
        //format input
        $h=(int)$h;
        $w=(int)$w;
        $q=esc_attr($q);
        $geo=esc_attr($geo);
         ob_start();
?>
<script type="text/javascript" src="http://www.google.com/trends/embed.js?hl=en-US&q=<?php echo $q;?>&geo=<?php echo $geo;?>&cmpt=q&content=1&cid=TIMESERIES_GRAPH_0&export=5&w=<?php echo $w;?>&h=<?php echo $h;?>"></script>
<?php
return ob_get_clean();
}
add_shortcode("trends","wps_trend");

Once you saved your functions.php file, you can now use the shortocode in your posts and pages. Here is an example of usage:

[trends h="450" w="500" q="wpsnipp,wordpress,+wordpress+theme,+wordpress+plugin,+wordpress+snippets" geo="US"]

Thanks to Kevin Chard for the shortcode!

  1. Cool..

    Thanks.

  2. In the shortcode, what does the “+” character do? I know “q” is for query…
