Post Affiliate Pro – Direct Linking
Post Affiliate Pro is an affiliate tracking/affiliate program software developed by Quality Unit. It is one of the most popular choices for establishing self-hosted/managed affiliate program.
Visitor referred through DirectLink is recognized by the HTTP_REFERER information sent by the browser – that will be address of affiliate page where the link is clicked. Post Affiliate Pro stores information about affiliate pages in the database and when it finds a match between HTTP_REFERER and affiliate page stored in the database commission is assigned to appropriate affiliate. This is the best option in terms of SEO and protection of affiliate commissions as visitor will not damage or remove the affiliate parameters from URL. The only thing – you have to manually add and approve affiliate pages/domains that are allowed for direct linking so you can make sure you get quality traffic.
