Keywords
See Search Terms.

Keyword search
A search for documents containing one or more words that are specified by a user.

Landing Page
The specific web page that a visitor ultimately reaches after clicking a search engine listing. Marketers attempt to improve conversion rates by testing various landing page creative, which encompasses the entire user experience including navigation, layout and copy. Source: Did-It.com

Link Popularity
A raw count of how "popular" a page is based on the number of backlinks it has. It does not factor in link context or link quality, which are also important elements in how search engines make use of links to impact rankings.

Link Text
The text that is contained within a link. For example, search engine is a link that contains the link text "search engine."

Listings
The information that appears on a search engine's results page in response to a search.

Meta Search Engine
A search engine that gets listings from two or more other search engines, rather than through its own efforts.

Meta Tags
Information placed in a web page not intended for users to see but instead which typically passes information to search engine crawlers, browser software and some other applications.

Meta Description Tag
Allows page authors to say how they would like their pages described when listed by search engines. Not all search engines use the tag.

Meta Keywords Tag
Allows page authors to add text to a page to help with the search engine ranking process. Not all search engines use the tag.

Meta Robots Tag
Allows page authors to keep their web pages from being indexed by search engines, especially helpful for those who cannot create robots.txt files. The Robots Exclusion page provides official details.

Organic Listings
Listings that search engines do not sell (unlike paid listings). Instead, sites appear solely because a search engine has deemed it editorially important for them to be included, regardless of payment. Paid inclusion content is also often considered "organic" even though it is paid for. This is because that content usually appears intermixed with unpaid organic results.

Outbound Links
Links on a particular web page leading to other web pages, whether they are within the same web site or other web sites.

Paid Inclusion
(Source: Did-It.com)
Advertising program where pages are guaranteed to be included in a search engine's index in exchange for payment, though no guarantee of ranking well is typically given. For example, Looksmart is a directory that lists pages and sites, not based on position but based on relevance. Marketers pay to be included in the directory, on a CPC basis or per-URL fee basis, with no guarantee of specific placement. Also see XML Feeds.

PPC
Stands for pay-per-click and means the same as cost-per-click. See Cost Per Click.

Paid Listings
Listings that search engines sell to advertisers, usually through paid placement or paid inclusion programs. In contrast, organic listings are not sold.

Pay-for-Performance
Term popularized by some search engines as a synonym for pay-per-click, stressing to advertisers that they are only paying for ads that "perform" in terms of delivering traffic, as opposed to CPM-based ads, where ads cost money, even if they don't generate a click.

Pay-Per-Click
see Cost Per Click.

Paid Placement
Advertising program where listings are guaranteed to appear in response to particular search terms, with higher ranking typically obtained by paying more than other advertisers. Paid placement listings can be purchased from a portal or a search network. Search networks are often set up in an auction environment where keywords and phrases are associated with a cost-per-click (CPC) fee. Overture and Google are the largest networks, but MSN and other portals sometimes sell paid placement listings directly as well. Portal sponsorships are also a type of paid placement.

Phrase search
A search for documents containing a exact sentence or phrase specified by a user.

Position
See Rank.

Precision
The degree in which a search engine lists documents matching a query. The more matching documents that are listed, the higher the precision. For example, if a search engine lists 80 documents found to match a query but only 20 of them contain the search words, then the precision would be 25%.

Proximity search
A search where users to specify that documents returned should have the words near each other.

Query
See Search Terms.

Rank
How well a particular web page or web site is listed in a search engine results. For example, a web page about apples may be listed in response to a query for "apples." However, "rank" indicates where exactly it was listed -- be it on the first page of results, the second page or perhaps the 200th page. Alternatively, it might also be said to be ranked first among all results, or 12th, or 111th. Overall, saying a page is "listed" only means that it can be found within a search engine in response to a query, not that it necessarily ranks well for that query. Also called position.

Reciprocal Link
A link exchange between two sites. Source: Webmaster World Forums

Registration
See Submission.

Results Page
After a user enters a search query, the page that is displayed, is call the results page. Sometimes it may be called SERPs, for "search engine results page." Source: Webmaster World Forums

Robot
see Crawler.

Robots.txt
A file used to keep web pages from being indexed by search engines. The Robots Exclusion page provides official details.

ROI
Stands for "Return On Investment" and refers to the percentage of profit or revenue generated from a specific activity. For example, one might measure the ROI of a paid listing campaign by adding up the total amount spent on the campaign (say $200) versus the amount generated from it in revenue (say $1,000). The ROI would then be 500 percent. Source: Did-It.com
