# Search Engine Type Parameter

#### WT.srch

`WT.srch=SearchEngineType`

The Search Engine Type parameter in the query string of the URL from a referring search engine identifies the link as one for a paid search engine phrase.

Webtrends Analytics uses this parameter for Custom Reporting and Visitor History to differentiate a paid search engine from a reference to an organic search engine. Only `WT.srch=1` has meaning. No other values are defined or recognized.

          Note

          

Search engine results using `WT.srch=1` are limited to only those search engines that are listed on the Webtrends search engine availability list. Using `WT.srch=1` will not produce search engine campaign results for search engines that are not recognized by Webtrends.

          Note

          

**Visitor Data Mart** also uses this parameter. For more information, see “Configuring Your Web Site to Collect Visitor Data Mart Data” in *Visitor Data Mart User’s Guide*.
