Affiliate marketing overlaps with other internet marketing methods to some degree, because affiliates are using the same methods as most of the merchants themselves do. Those methods include organic search engine optimization, paid search engine marketing, and email marketing.

Currently the most active sectors for affiliate marketing are the adult, gambling and retail sectors.The three sectors expected to experience the greatest growth are the mobile phone, finance and travel sectors.

Merchants like affiliate marketing, because in most cases, it is a "pay for performance      model", meaning the merchant does not incur a marketing expense unless results are realized. Some merchants run their own affiliate programs (In House) while others use third party services provided by intermediaries to track traffic or sales that are referred from affiliates.
   
The increase of number of internet businesses in combination with the increased number of people that trust the current technology enough to do shopping and business online caused and still causes a further maturing of affiliate marketing. The opportunities to generate considerable amount of profit is still available for the able webpreneur.
