Hit
Each element of a requested page recorded as an individual entry on a web site's server log file. The number of hits bears no relationship to the number of pages downloaded.

Please note that the industry no longer recognises the term “Hit” as a valid metric for measuring traffic to a particular website as the number of hits bears no relationship to the number of pages downloaded, and therefore cannot be used to determine estimates of consumers’ opportunities to see (OTS).

PV % Change
Percentage change in Page Views compared to previous corresponding month.

Panel
A group of pre-screened respondents who have expressed a willingness to participate in survey or customer feedback sessions. Also known as a customer advisory panel, proprietary panel or an online research panel. A panel, whether for TV, Radio or Internet - is a continuous sample of people that are chosen with like characteristics to that of the universe to be measured. A panel should be randomly selected so that people with like characteristics have an equal chance of being selected. A panel should be representative so that its behaviour (i.e. viewing, listening or surfing) can be projected up to the universe being measured. Please note that samples and panels are similar except for ONE fact. Panels are used for REPEAT observations whereas samples are interviewed ONCE. Therefore only panels can deliver "longitudinal" analysis like Reach.

People Count
The 'People' count metric takes our directly measured Unique Browser figure and divides it a country-specific Device Factor that is calculated from longitudinal studies run by Effective Measure to ascertain the impact of multiple device use (home, work, mobile phones, tablets etc.) as well as the impact of multiple browser use.
For tagged websites, a 'People' metric is listed as well as a Unique Browser figure. For sites only measured through the panel, only a 'People' figure is presented.

Property
A consolidation of multiple domains and URLs that are owned by a company, corporation, organization, government agency, private group or other institution that has a controlling interest in those Domains or URLs.  A Domain or Unique Site can exist in only one Property to prohibit double counting. A site, which is co-owned, can be placed in only one Property. A Property includes all Domains belonging to that Property and all sites that automatically roll into those Domains.  It should be noted that an organisation can have more than one Property provided the above criteria are satisfied - this is unusual because companies generally wish to group all domains to achieve a higher ratings.

Proxy (server)
A relay server allowing an access provider, or other intermediary, to store locally the web pages requested most often. Queries managed by proxies are not usually passed on to the main site and are thus not included in the latter's audience, unless a particular procedure is used.

Sub Domain/Section
Effective Measure allows listing of sub-domain/sections/sub-sections in our dashboard. We can map the traffic by the path matcher or sub-domain to a section and roll-up traffic to parent domain.

E.g. of sub-domains: abc.com/news|news.abc.com can roll up the traffic to abc.com
*sub-domains should have a host matcher which match back to parent domain, eg. abc.com

T

Tag Code
The JavaScript or Beacon code placed on a page to collect visitation data about the users.

Tagged Website

Unique Browser vs. Unique Visitors
The Unique Browser (UB) figure in Effective Measure is the most accurate representation of the Digital Helix methodology, whereas the Unique Visitors (UV) figures include additional traffic from "untrusted" cookies. When we are unable to set or retrieve valid cookies on a device, this traffic is flagged and excluded from the UB figure. Portions of this traffic are included in the UV figure however, and more closely resemble the way some other measurement systems approach their methodology.

Unique Audience (UA) vs. Unique Visitors (UV)
UA represent absolute visitor regardless of how many browser used on the machine whereas UV's are based on number of time a visitor visited a site in a given period.
