Unique Browser & Unique visitor & Unique user & Unique Device & Unique Cookie

Unique Browser

An identified and unduplicated Cookied Browser that accesses Internet content or advertising during a measurement period. This definition requires taking account for the potentially inflationary impact of cookie deletion among certain of the cookied browsers that access Internet content.

Unique Cookie

A count of unique identifiers…that represents unduplicated instances of Internet activity (generally visits) to Internet content or advertising during a measurement period.

Unique Device

An unduplicated computing device that is used to access Internet content or advertising during a measurement period. A count of unduplicated devices necessarily accounts for multiple browser usage on an individual computer or other computing device.

Unique user

Unique individual or browser which has accessed a site or application and has been served unique content and/or ads such as e-mail, newsletters, interstitials or pop-under ads. Unique visitors can be identified by user registration, cookies, or third-party measurement like ComScore or Nielsen. Reported unique visitors should filter out bots. See iab.net for the audience reach measurement guidelines.

Unique visitor

Unique individual or browser which has accessed a site or application and has been served unique content and/or ads such as e-mail, newsletters, interstitials or pop-under ads. Unique visitors can be identified by user registration, cookies, or third-party measurement like ComScore or Nielsen. Reported unique visitors should filter out bots. See iab.net for the audience reach measurement guidelines.

Unique listeners/streamers : A metric specific to Digital Audio

The size of the audience for a given audio program, piece of content, or advertising message. Typically ‘listeners’ and ‘streamers’ are interchangeable.

NAI - (Network Advertising Initiative)

A cooperative group of network advertisers which has developed a set of privacy principles in conjunction with the Federal Trade Commission. The NAI provides consumers with explanations of Internet advertising practices and how they affect both consumers and the Internet. See networkadvertising.org for more information.

Video Ads

In-Banner Video Ads

Leverage the banner space to deliver a video experience as opposed to another static or rich media format. The format relies on the existence of display ad inventory on the page for its delivery

In-Page Video Ads

Delivered most often as a stand alone video ad and do not generally have other content associated with them. This format is typically home page or channel based and depends on real estate within the page dedicated for the video player.


In-Stream Video Ads


Played before, during or after the streaming video content that the consumer has requested. These ads cannot typically be stopped from being played (particularly with pre-roll). This format is frequently used to monetize the video content that the publisher is delivering. In-Stream ads can be played inside short or long form video and rely on video content for their delivery. There are four different types of video content where in-stream may play, UGC (User Generated Content/Video), Syndicated, Sourced and Journalistic.

In-Text Video Ads

Delivered from highlighted words and phrases within the text of web content. The ads are user activated and delivered only when a user chooses to move their mouse over a relevant word or phrase.

Cache busting

The process by which sites or servers serve content or HTML in such a manner as to minimize or prevent browsers or proxies from serving content from their cache. This forces the user or proxy to fetch a fresh copy for each request. Among other reasons, cache busting is used to provide a more accurate count of the number of requests from users.

What is Cache?

Memory used to temporarily store the most frequently requested content/files/pages in order to speed its delivery to the user. Caches can be local (i.e. on a browser) or on a network. In the case of local cache, most computers have both memory (RAM), and disk (hard drive) cache.

Behavioral targeting

Using previous online user activity (e.g., pages visited, content viewed, searches, clicks and purchases) to generate a segment which is used to match advertising creative to users (sometimes also called Behavioral Profiling, Interest-based Advertising, or online behavioral advertising). Behavioral targeting uses anonymous, non-PII data.

What is the Web crawler?

web crawler (also known as an automatic indexerbotWeb spiderWeb robot) is a software program which visits Web pages in a methodical, automated manner.
This process is called Web crawling or spidering, and the resulting data is used for various purposes, including building indexes for search engines, validating that ads are being displayed in the appropriate context, and detecting malicious code on compromised web servers.
Many web crawlers will politely identify themselves via their user-agent string, which provides a reliable way of excluding a significant amount of non-human traffic from advertising metrics. The IAB (in conjunction with ABCe) maintains a list of known user-agent strings as the Spiders and Bots list. However, those web crawlers attempting to discover malicious code often must attempt to appear to be human traffic, which requires secondary, behavioral filtering to detect.
Most web crawlers will respect a file called robots.txt, hosted in the root of a web site. This file informs the web crawler which directories should and shouldn't be indexed, but does not enact any actual access restrictions.
Technically, a web crawler is a specific type of bot, or software agent.

Ad Serving Options

Ad Serving Options 

There are two methods by which the winning bidder can return ad markup to the exchange. In either case, the ad markup is either XHTML if the bidder is responding with a banner or VAST XML if responding with a VAST video.

1 Ad Served on the Win Notice
In this method, ad markup is returned to the exchange is via the win notice. In this case, the
response body of the win notice call (e.g., invoking the “nurl” attribute) contains the ad markup
and only the ad markup; there must be no other structured data in the response body. Using
this method, the “adm” attribute in the “bid” object must be omitted.

2 Ad Served in the Bid
In this method, ad markup is returned directly in the bid itself. This is accomplished via the
“adm” attribute in the “bid” object. If both the “adm” attribute and win notice return data, the
“adm” contents will take precedence.

3 Comparison of Ad Serving Approaches
Each of the ad serving methods has its own advantages that may be of varying importance to
either the exchange or the bidder.

            3.1 Ad Served in the Bid
                   1   Potential Concurrency: The exchange can choose to return that ad markup and
                        call the win notice concurrently, thereby improving user experience.

                   2  Reduced Risk of Forfeiture: A forfeit is the scenario in which a bidder wins, but
                       forfeits due to technical failure serving the ad. This can occur when serving on
                       the win notice (e.g., win notice call failure), but is mitigated by including the ad
                       in the bid.
               
            3.2 Ad Served on the Win Notice

1 Reduced Bandwidth Costs: Serving ad markup only upon winning can save large
                    amounts of bandwidth usage, the costs for which can mount up over high volumes.


2 Additional Bidder Flexibility: Bidders may typically know the ad they will serve
                           at the time of bid, but this provides an additional optional decision point after
                           the settlement price has been established.
