You did a pretty good site and put all PHP-codes showing the information on the credit cards. You sorted cards according to different criteria: rewards programs, instant decision, low apr, etc. The next step is organizing a "Search for Credit Card System". For example your visitor heard something about a credit card. But does not remember its name or bank's name. All he remembers is a couple of words from credit cards' name (e.g."aadvantage"). Your visitor types it in search area and clicks "search" button and receives a list of credit cards from Acclaim Network Affiliate Program that have the word in its name.
To have this search system you have just put our PHP-code from Codes Page. It will be like this (if your id is 'yapl'):
Try to search for 'aadvantage' or 'chase' or 'universal' you'll have a new window opened with a list of credit cards containing the word in its name. The links leading to merchant's site will be your links from Acclaim Network Affiliate Program. So if visitor clicks you receive commission.
