WIKI definition: A search engine results page (SERP) is the listing of results returned by a search engine in response to a keywordquery.

A SERP may refer to a single page of links returned, or to the set of all links returned for a search query.
(Google Support Page – AdWords): The 1-10 Quality Score reported for each keyword in your account is an estimate of the quality of your ads and landing pages triggered by that keyword. Having a high Quality Score means that our systems think your ad and landing page are relevant and useful to someone looking at your ad. You can find out your Quality Score for any of your keywords.
Google’s description of Quality Score (QS) reads as: Quality Score is calculated in real-time, every time your keyword matches a search query – essentially, every time your keyword has the potential to trigger an ad.
Quality Score is used in several different ways, including influencing your keywords’ actual cost-per-click (CPC) and estimating the first page bids that you see in your account. It also partly determines if a keyword is eligible to enter the ad auction that occurs when a user enters a search query and, if it is, how high the ad will be ranked.
