Answer:
Search engine marketing
Explanation:
Search engine marketing is a rapid growing segment of the Internet marketing.
It consists basically at bidding on keywords within a search engine (like Google, Bing, Yahoo), so when a user enters those keywords your ads is displayed on top of the search engine results, and hopefully before your competitors for those same words.
The ads can be text ads, image ads or even video ads. But the largest portion of the market is still with text ads.
