Hi, For my software, I currently use the eSellerate (owned by DigitalRiver) affiliate program where downloads automatically gets "tagged" with affiliate ID (which gives better a quite good tracking, even if user first buys after e.g. 30 days), but I am wondering what the alternatives are and if you have any suggestions? This is may page with more information: http://www.micro-sys.dk/affiliates/ It is primarily geared for my A1 (e.g. sitemap generator, keyword research, website analyzer) suite of programs. Is there anything in particular I need to add of information? Do you suggest using a different affiliate program?
