This keyword source option is for advanced users only.

You can use your own php function to generate keywords used for product lookups.

To use this option you must have a function in your functions.php file that looks like this:

function wpbounce_custom_keyword_source($advertiser = FALSE, $post_id = 0)
{
$my_custom_kws = array(‘keyword one’, ‘keyword two’);
return $my_custom_kws;
}

The plugin will pass $advertiser and $post_id
$advertiser – can either be amzn for Amazon or epn for eBay ePN add-on.
