this visitor converted into a sale ( tracked using the piwik API using the visitor id from the cookie with the ip number) the sale shows up fine in the visitor log
I would expect the conversion attributed to the campaign however the referrerType is ‘search’ and the campaing does not show up in the visitor log.
Multi Channel Conversion Attribution, also known as Cross Channel Attribution, lets you assign a value to each visit prior to a conversion or prior to a sale. By default, Piwik lets you only know the referrer of the last non-direct visit when a conversion happens. However, in reality, multiple channels contribute to a conversion as a visitor often visits a website several times before they convert a goal. By applying different attribution models, you get a better view on which channels actually lead to a conversion. This helps you finding out where to spend your money best when acquiring visitors.
