Text-based advertisements returned by a search engine, most commonly on a SERP. The placement of this ad has been paid for by the company (qv organic listings). A hyperlink is included, so that interested consumers may click on the advertisement and go to the advertised site.

They may also appear on Web sites that allow advertising ( contextual ads).

The ads that show up on Google next to the regular search results, also called paid search results or simply ads or text ads

Paid advertising which displays next to the natural search results. Customers can click on the ad to visit the advertiser's website. This is how the search engines make their money. Advertisers set their ads up to display whenever someone searches for a word which is related to their product or service. These ads look similar to the natural search results, but are normally labeled 'Sponsored Links', and normally take up a smaller portion of the window. These ads work on a Pay-Per-Click (PPC) basis (i.e. the advertiser only pays when someone clicks on their ad).

These are SEA advertisements. They appear in prominent positions in search engine results pages and specific content websites. They are usually clearly separated from the natural search listings.
