About ved decode

The ved decode library consists of:

The ved_decode functions

Each function is a standalone function that simply decodes the ved parameter and nothing else.  It’s not a full-scale protobuf decoder, and we’ve kept the code as simple and as short as possible.

Currently there are implentations in:


You can use ved_analytics.js to decode the ved parameter directly from the document.referrer

Load it like this:

<!-- Include both these scripts or copy them into your main JavaScript file -->
<!--[if lt IE 10]>
    <script type="text/javascript"
<script type="text/javascript"

Note that the base64 library is necessary for Internet Explorer 9 and below.

The script sets the global variable VedDecode which has the following properties:

Property Description
VedDecode.ved (object) the raw ved parameter values
VedDecode.linkIndex (integer) position of link on page (starting from 1)
VedDecode.linkType (string) type of link (e.g. "breadcrumb", "sitelink")
VedDecode.resultPosition (integer) number of result on page (starting from 1)
VedDecode.subResultPosition (integer) number of sub-result in set of results (starting from 1) (integer) page of results (starting from 1)

Please see the example scripts for how to go about importing the data:
