Cloaking: In terms of search engine marketing, this is the act of getting a search engine to record content for a URL that is different than what a searcher will ultimately see. It can be done in many technical ways. Several search engines have explicit rules against unapproved cloaking. Those violating these guidelines might find their pages penalized or banned from a search engine's index. As for approved cloaking, this generally only happens with search engines offering paid inclusion program.
Click Fraud: A type of internet crime that occurs in pay per click online advertising when a person, automated script, or computer program imitates a legitimate user of a web browser clicking on an ad, for the purpose of generating a charge per click without having actual interest in the target of the ad's link.
Content Management System (CMS): a software platform that aids in the management of content on a Web site.
Contextual Link Ads/Inventory: To supplement their business models, certain text-link advertising networks (like Google) have expanded their network distribution to include "contextual inventory". Most vendors of "search engine traffic" have expanded the definition of Search Engine Marketing to include this contextual inventory. Contextual or content inventory is generated when listings are displayed on pages of Web sites (usually not search engines), where the written content on the page indicates to the ad-server that the page is a good match to specific keywords and phrases. Often this matching method is validated by measuring the number of times a viewer clicks on the displayed ad. These ads typically do not perform as well as traditional text ads on search engines, but the lower cost justifies the expense.
Conversion: An action that signifies a completion of a specified activity. For many sites, a user converts if they buy a product, sing up for a newsletter, or download a file. The conversion rate is the percentage of visitors who do convert. Cookie deletion can have an impact on your conversion rate because if a cookie is being systematically deleted, repeat visitor rates will be under-counted and new visitor rates will be over-counted, thus skewing the conversion rate metric by which you analyze your site's overall effectiveness.
Conversion Funnel: The series of steps that move a visitor towards a specified conversion event, such as an order or registration signup. See also abandonment.
Conversion Rate: The relationship between visitors to a web site and actions considered to be a "conversion," such as a sale or request to receive more information. This metric is often expressed as a percentage.

Cost-per-Click (CPC): System where an advertiser pays an agreed amount for each click someone makes on a link leading to their web site. Also known as PPC or paid listings.
Cost-per-Thousand (CPM): System where an advertiser pays an agreed amount for the number of times their ad is seen by a consumer, regardless of the consumer's subsequent action. This term is heavily used in print, broadcasting and direct marketing, as well as with online banner ad sales. CPM stands for "cost per thousand," since ad views are often sold in blocks of 1,000. The M in CPM is Latin for thousand.
Crawler/Spider/Robot: Component of search engine that indexes web sites automatically. A search engine's crawler (also called a spider or robot), copies web page source code into its index database and follows links to other web pages.

Directories: A type of search engine where listings are gathered or reviewed by humans, rather than by search engine crawlers. In directories, web sites are often reviewed, summarized in about 25 words and placed in a particular category. The largest and most popular directory site is Yahoo!
Domain: An area in the Internet specified by a URL address. The top-level domain is at the end after the dot and the second-level domain comes before it, and shows where in the top-level domain the address can be found. For example in www.xyz.com, ".com" is the top-level domain and "xyz" is the second level domain.
Domain Name: The text name that corresponds to a numeric IP address of a computer on the Internet.
Doorway/Landing/Gateway/Bridge/Jump Pages: A web page created expressly in hopes of ranking well for a term in a search engine's organic/non-paid listings and which itself does not deliver much information to those viewing it. Instead, visitors will often see only some enticement on the doorway page leading them to other pages, or they may be seamlessly redirected to a real page within the existing web site. With cloaking, visitors may never see the doorway page at all. Several search engines have guidelines against doorway pages, though they are more commonly allowed in through paid inclusion programs.
E

F
First Party Cookie: For most business models, first-party cookies are regarded as the most reliable method to measure visitor activity. Whereas a third-party cookie is usually set by an analytics vendor, (an entity with whom the user does not have a relationship), a first-party cookie is set by the business, an organization with whom the Web site visitor has specifically chosen to do business. Because of this relationship, first-party cookies are deemed more secure by the user. Also seecookies.

Opt-in: This permission-based email communication requires customers to verify the opt-in method before their e-mail addresses can be used to communicate with them.
Organic/Natural 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.

Dynamic pages are created with variables and do not exist anywhere in a static form. Forms are scripted pages which get information from a visitor that gets passed back to the server.
Page Tag: A piece of JavaScript code embedded on a web page and executed by the browser when the page is viewed. See also log files.
Page View: is generally defined as a request to load a single page of a website. On the web, a page request would result from a web surfer clicking on a link on another page that points to the page in question. See also hit.

Recency: The number of days since a visitor's most recent visit during a reporting period.
Referrals: The location that visitors come from, particularly the sites, search engines or directories. Relationship Marketing: Relationship marketing is a type of marketing that traces its roots to direct response marketing.

Examples of spam include the creation of nonsensical doorway pages designed to please search engine algorithms rather than human visitors, or a heavy repetition of search terms on a page to increase keyword density. .
Spider: An automated software program that gathers pages from the Internet.
Submission: The act to submitting a URL for inclusion into a search engine's index. Unless done through paid inclusion, submission generally does not guarantee listing. In addition, submission does not help with rank improvement on crawler-based search engines unless search engine optimization efforts have been implemented. Submission can be done manually (i.e., you fill out an online form and submit) or automated, where a software program or online service may process the forms behind the scenes.
Suffix: The last part of a domain that can be used to identify the type of organization or location of a site.

XML Feeds: A form of paid inclusion where a search engine is "fed" information about pages via XML, rather than gathering that information through crawling actual pages. Marketers can pay to have their pages included in a spider based search index either annually per URL or on a CPC basis based on an XML document representing each page on the client site. New media types are being introduced into paid inclusion, including graphics, video, audio, and rich media. These feeds are commonly used for Shopping Feeds.
Z
Zero Latency: Latency is a time delay between the moment something is started, and the moment one of the effects of that event begins. When there is no time lapse between the event and the effect, it's called zero latency.
