That's OK to ask, when I first started I didn't knew that either.
Well, all that random ramble of letters and numbers is the HTML code from a banner on one of Maxbounty's offers.
The first link in that code
Code:
http://www.mb01.com/lnk.asp?o=4076&c=50933&a=91443
is your affiliate link where
o=4076 stands for the offer you want to promote and
a=91443 stands for the affiliate that is promoting that offer.
In other words, you are affiliate nr. 91443 and you promote the offer nr. 4076.
The second link in that code
Code:
http://www.mb01.com/getimage.asp?m=2688&o=4076&i=50933.dat
is the image link.
where
o=4076 is (again) the offer nr. and
i=50933 is the image nr.
This entire code forms a nice clickable banner that you can put up on your site or anywhere where you are allowed to put HTML codes/banner ads.
If you want to promote that offer by posting in forums, chat-boards, articles etc. than you don't need the whole code (it wont be accepted anyway). All you need is your affiliate link (the first one).
Hope this helps you.
Good Luck !
