The General Glossary of Terms is a document to standardize the terms used, enabling communication and increasing comprehension between e-planning and their clients:

Adserver:
Management system of online ads (banners). An advertiser places a banner on a website with the intention to be seen by visitors to this site. In order to know if the campaign is efficient, it is necessary to analyze a series of statistical concepts of the banners, which definitions are included as follows.

Advertiser:
Organization hiring an online campaign through banners. The website may grant the advertiser a password to gain access to e-planning to check the reports of their campaigns.

Banner:
Graphic ad placed on a website. It normally consists of an ad image with a link to another website containing more information. Banners are graphic files with some features. Type of graphic format: according to how they have been designed, banners have a graphic format indicated by the extension of their file name (JPG, GIF or PNG) or even may be animated (GIF, Flash). Banners have a definite size (dimensions) measured in pixels.

CPC:
This is a way to market campaigns by a definite number of clicks. The Cost per Click of a site is the amount to be charged to an advertiser per each click on their banners. For example, if an advertiser hires a 1000-click campaign with a CPC of 20 cents per dollar, he should pay the site 200 dollars.

CPM:
This is a way to market campaigns by a definite number of impressions. The acronym stands for Cost per Mille. For example, if a website sells its traffic at 5 dollars per CPM, this means that an advertiser should pay 5 dollars to obtain 1000 impressions of their banners on the site.

Click:

CTR or clicks rate:
Percentage of clicks the ad had on the number of impressions thereof.

Space:
Position of a page where banners are published. In e-planning, the spaces may have a fixed size in pixels or they may vary. In this last case, they enable the publication of banners of any size.

Campaigns Pool:

HTML:
Language used to design websites. The acronym in English stands for HyperText Markup Language.

Impression:
