The Fundamentals of Web Analytics

A Glossary of Terms

What's a dashboard? What does KPI stand for? What's the difference between Organic and PPC search results? This glossary provides a handy guide to commonly used web marketing terms.


A - B - C - D - E - F - G - H - I - J - K - L - M - N - O - P - Q - R - S - T - U - V - W - X - Y - Z
A
Abandonment: When a visitor exits or leaves a conversion process on a website and does not return later in the session. See also conversion funnel.
Acknowledgement Page: A page displayed after a visitor completes an action or transaction. For example, a thank-you or a receipt page. An Acknowledgement Pages is often important in Scenario Analysis, where it is an indicator of a completed scenario.
Acquisition: The process of attracting visitors to your site.
ACT: After-Click Tracking is the recording the activity path of a visitor to a site after they have clicked on an email link.
Actionable data: Information that allows you to make a decision or can be made use of in any way. See also forward-looking metrics.
Ad: A link that takes a visitor to a web site when clicked on, usually graphic or text. See also banner ad.
Ad Click: A click on an advertisement on a web site which takes a user to another site. See also ad view.
Ad Hoc Query: A non-standard inquiry posed as the need arises. See also query.
Ad View: A web page that presents an ad. There may be more than one ad on an ad view. Once visitors have viewed an ad, they can click on it.
Affiliate Marketing: A method of promoting web businesses in which an affiliate is rewarded for providing customers. Compensation could be made based on a value for visits, subscriptions, leads, sales, and so on. See also PPC.
Aggregate Data: A summary of collected information which groups data together without record-level statistics.
Analytics: see web analytics
API: Application Programming Interface is a system that a computer or application supplies to users in order to allow requests for service to be made of it by other computer programs. For example, an API might describe how to draw icons or windows using a library that has been created for that purpose.
ASP: Active Server Pages are a set of software components that run on a web server and let developers build dynamic web pages.
Attrition: The erosion of your customer base over time. The opposite of customer retention.
Authentication: The technique by which access to Internet or intranet resources requires the user to enter a username and password as identification.
Average Lifetime Value: The average of the lifetime values of all the visitors during the reporting period, where each visitor's lifetime value is the total monetary value of a visitor's past orders since visitor tracking began.







B
Bandwidth: Measure, in kilobytes of data transferred, of the traffic on a site.
Banner ad: An advertisement embedded on a web page usually intended to drive traffic to a different website by linking to the advertiser's site. The Interactive Advertising Bureau (IAB) has created a standard set of banner ad sizes (Medium Rectangle, Rectangle, Leaderboard, Wide Skyscraper) into a set of guidelines called the Universal Ad Package).
Bot: See robot.
Bounce: See bounce rate and email bounce
Bounce Rate: The percentage of entrances on a web page that result in an immediate exit from the web site.
Browser: A program used to locate and view HTML documents (Microsoft Internet Explorer for example.)
Business Intelligence: While some would claim it's an oxymoron, business intelligence refers to a category of software and tools designed to gather, store, analyze, and deliver data in a user-friendly format to help organizations make more informed business decisions. Software types include dashboarding, data mining, data warehouses, and other information systems.







C
Campaign Creative: A "Creative" describes the characteristics of a marketing activity, such as color, size and messaging-for example, a "Buy Now" graphic.
Client: The browser used by a website visitor.
Client Error: An error that occurs because of an invalid request by the visitor's browser. See also return code.
CNAME: A Canonical NAME record makes one domain name an alias of another.
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. See also abandonment.
Convert: See conversion.
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.

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.
