Affiliate Marketing is an Internet-based marketing practice in which a business rewards one or more affiliates for each visitor or customer brought about by the affiliate's marketing efforts. It is an application of crowdsourcing.

The Affiliate Marketing industry has four core players at its heart: the Merchant (also known informally as 'Retailer' or 'Brand'), the Network, the Publisher (also known informally as 'the Affiliate') and the Customer. The market has grown sufficiently in complexity to warrant a secondary tier of players, including Affiliate Management Agencies, Super-Affiliates and Specialized Third Parties vendors.

Affiliate marketing overlaps with other Internet marketing methods to some degree, because affiliates often use regular advertising methods. Those methods include organic search engine optimization, paid search engine marketing, e-mail marketing, and in some sense display advertising. On the other hand, affiliates sometimes use less orthodox techniques, such as publishing reviews of products or services offered by a partner.

Affiliate marketing—using one website to drive traffic to another—is a form of online marketing, which is frequently overlooked by advertisers.[citation needed] While search engines, e-mail, and website syndication capture much of the attention of online retailers, affiliate marketing carries a much lower profile. Still, affiliates continue to play a significant role in e-retailers' marketing strategies

Weblog software (also called blog software or blogware) is software designed to simplify the creation and maintenance of weblogs. As specialized content management systems, weblog applications support the authoring, editing, and publishing of blog posts and comments, with special functions for image management, web syndication, and moderation of posts and comments.

Equipment colocation (aka co-location) is when an organization pays to rent space in another organization's networked facility. It is a common practice for web hosting, as it allows a company to put their equipment into a controlled, reliable, networked environment without having to build or buy their own data center. If your company or other organization needs to be on the Web, colocation may be a good option – especially if you have special requirements such as non-standard equipment.

There are many reasons why colocation may make sense for you. One may be cost – by renting space in another company's data center, you can simply move your equipment into that location and “plug it in” - the other company takes care of keeping it cooled and supplying it with power and internet access. One scenario in which this really makes sense is if your organization has a server already running on the premises, but is having problems keeping it online, and keeping it secure. By colocating that server to another company's data center, all you need to do is unplug the server, drive it over to the new location and plug it in!

Another common reason for equipment co-location is to allow an organization to spread its online resources around geographically. This may be useful in terms of performance – by allowing equipment to help deal with traffic coming from that geographical area. It also can offer some redundancy in case of natural disaster. For example, you can be sure that large online companies like google do not have “all their eggs in one basket” but instead have data centers scattered all over the globe. Of course building facilities all over the place is not feasible for a lot of organizations – but by renting colocation space in a few data centers scattered around, your company could possible gain some benefit over concentrating everything in one location.

Contextual advertising is a form of targeted advertising for advertisements appearing on websites or other media, such as content displayed in mobile browsers. The advertisements themselves are selected and served by automated systems based on the content displayed to the user.

Cost per impression, often abbreviated to CPI or CPM for Cost per thousand impressions, is a phrase often used in online advertising and marketing related to web traffic. It is used for measuring the worth and cost of a specific e-marketing campaign. This technique is applied with web banners, text links, e-mail spam, and opt-in e-mail advertising, although opt-in e-mail advertising is more commonly charged on a cost per action (CPA) basis although sometimes CPM is used.

An online advertisement impression is a single appearance of an advertisement on a web page. Each time an advertisement loads onto a user's screen, the ad server may count that loading as one impression. However, the ad server may be programmed to exclude from the count certain nonqualifying activity such as a reload, internal user actions, and other events that the advertiser and ad serving company agreed to not count. For online advertising, the numbers of views can be a lot more precise. When a user requests a web page, the originating server creates a log entry. Also, a third party tracker can be placed in the web page to verify how many accesses that page had. There are other advertising pricing structures, which are generally referred to as Cost Per Action (CPA) :

* CPC - Cost per click Through
* CPL - Cost per lead (lead usually meaning a free registration)
* CPS - Cost per sale
* dCPM - Dynamic CPM

CPI and/or Flat rate advertising deals are sometimes preferred by the publisher/webmaster because they will receive a more consistent fee proportional to the amount of traffic.

Today, it is very common for large publishers to charge for most of their advertising inventory on a CPM or CPT basis. A related term, effective cost per mille (CPM), is used to measure the effectiveness of advertising inventory sold (by the publisher) via a CPC, CPA, or CPT basis.

This type of advertising arrangement closely resembles television and print advertising methods for speculating the cost of an advertisement. Often, industry agreed approximates are used. With television, the Nielsen Ratings are used; print is based on the circulation a publication has.

Display advertising is a type of advertising that typically contains text (i.e., copy), logos, photographs or other images, location maps, and similar items. In periodicals, display advertising can appear on the same page as, or on the page adjacent to, general editorial content. In contrast, classified advertising generally appears in a distinct section, was traditionally text-only, and was available in a limited selection of typefaces.

Display advertisements are not required to contain images, audio, or video: Textual advertisements are also used where text may be more appropriate or more effective. An example of textual advertisements is commercial messages sent to mobile device users.

A domain name is an identification label that defines a realm of administrative autonomy, authority, or control in the Internet, based on the Domain Name System (DNS).

Domain names are used in various networking contexts and application-specific naming and addressing purposes. They are organized in subordinate levels (subdomains) of the DNS root domain, which is nameless. The first-level set of domain names are the top-level domains (TLDs), including the generic top-level domains (gTLDs), such as the prominent domains com, net and org, and the country code top-level domains (ccTLDs). Below these top-level domains in the DNS hierarchy are the second-level and third-level domain names that are typically open for reservation by end-users that wish to connect local area networks to the Internet, run web sites, or create other publicly accessible Internet resources. The registration of these domain names is usually administered by domain name registrars who sell their services to the public.

Individual Internet host computers use domain names as host identifiers, or hostnames. Hostnames are the leaf labels in the domain name system usually without further subordinate domain name space. Hostnames appear as a component in Uniform Resource Locators (URLs) for Internet resources such as web sites (e.g., en.wikipedia.org).

Domain names are also used as simple identification labels to indicate ownership or control of a resource. Such examples are the realm identifiers used in the Session Initiation Protocol (SIP), the DomainKeys used to verify DNS domains in e-mail systems, and in many other Uniform Resource Identifiers (URIs).

An email hosting service is an Internet hosting service that runs email servers.

Email hosting services usually offer premium email at a cost as opposed to advertising supported free email or free webmail. Email hosting services thus differ from typical end-user email providers such as webmail sites. They cater mostly to demanding email users and Small and Mid Size (SME) businesses, while larger enterprises usually run their own email hosting service. Email hosting providers allow for premium email services along with custom configurations and large number of accounts. In addition, hosting providers manage user's own domain name, including any email authentication scheme that the domain owner wishes to enforce in order to convey the meaning that using a specific domain name identifies and qualifies email senders.

Most email hosting providers offer advanced premium email solutions hosted on dedicated custom email platforms. The technology and offerings of different email hosting providers can therefore vary with different needs. Email offered by most webhosting companies is usually more basic standardized POP3 based email and webmail based on open source webmail applications like Horde or Squirrelmail. Almost all webhosting providers offer standard basic email while not all email hosting providers offer webhosting.
