The 10/90 Rule

If your have a budget of $100 to make smart decisionsabout your websites . . . invest $10 in tools and vendorimplementation and spend $90 on Analysts with bigbrains.

The 10/90 Rule

I Websites are massively complex

I Tools are only about the data

I Complex world

I Tribal knowledge (unwritten rules, missing metadata,actions,...)

Building Blocks Terms

Some definitions

[Page]A page is an analyst definable unit of content.

Flash, AJAX, media files, downloads, documents, and PDFs?

Some definitions

[Page]A page is an analyst definable unit of content.

Flash, AJAX, media files, downloads, documents, and PDFs?

Some definitions

[Pageviews]The number of times a page (an analyst-definable unit ofcontent) was viewed.

Vendors do make different distinctions in deciding what should becounted. Consult your tool provider for more information on yourimplementation.

Some definitions

[Visit/Sessions]A visit is an interaction, by an individual, with a websiteconsisting of one or more requests for ananalyst-definable unit of content (i.e. “page view”). If anindividual has not taken another action (typicallyadditional page views) on the site within a specified timeperiod, the visit session will terminate.

Visit → Several pageviewsRepresentation of the interaction of the visitor with the site

Some definitions

[Unique Visitors]The number of inferred individual people (filtered forspiders and robots), within a designated reportingtimeframe, with activity consisting of one or more visitsto a site. Each individual is counted only once in theunique visitor measure for the reporting period.

Authentication, either active or passive, is the most accurate wayto track unique visitors.Their activity will be over-represented unless they arede-duplicated.Blocked cookies!Related → New Visitor, Repeat Visitor (reporting period),Return Visitor (previous periods)

Visit Characterization

Some definitions

[Entry Page]The first page of a visit.

First page in the visit regardless of how the sessions are calculated

Some definitions

[Landing Page]A page intended to identify the beginning of the userexperience resulting from a defined marketing effort.

Landing pages are often optimized for specific keywords, audiences,or calls to action

Some definitions

[Exit Page]The last page on a site accessed during a visit, signifyingthe end of a visit/session.

In a tabbed or multi-window browser environment it should still bethe final page accessed that is recorded as the Exit Page though itcannot be definitively known that this was the last page the visitorviewed.

Some definitions

[Visit Duration]The length of time in a session. Calculation is typicallythe timestamp of the last activity in the session minusthe timestamp of the first activity of the session.

Some definitions

[Referrer]The referrer is the page URL that originally generated therequest for the current page view or object.

I Internal Referrer

I External Referrer

I Search Referrer

I Visit Referrer (session)

I Original Referrer (all visits)

Some definitions

[Click-through]Number of times a link was clicked by a visitor.

Click-throughs are typically associated with advertising activities,whether external or internal to the site. Note that click-throughsmeasured on the sending side (as reported by your ad server, forexample) and on the receiving side (as reported by your webanalytics tool) often do not match.

Some definitions

[Click-through Rate/Ratio]The number of click-throughs for a specific link dividedby the number of times that link was viewed.

Some definitions

[Page Views per Visit]The number of page views in a reporting period dividedby number of visits in the same reporting period.

Content Characterization

Some definitions

[Page Exit Ratio]Number of exits from a page divided by total number ofpage views of that page.

Page exit ratio should not be confused with bounce rate, which isan indicator of single-page-view visits on your site. Page exit ratioapplies to all visits regardless of length.

Some definitions

[Single-Page Visits]Visits that consist of one page regardless of the numberof times the page was viewed.

For a single-page visit, the entry page and exit page are the samepage.

Some definitions

[Single Page View Visits (Bounces)]Visits that consist of one page-view.

Some definitions

[Bounce Rate]Single page view visits divided by entry pages.

Conversion Metrics

Some definitions

[Event]Any logged or recorded action that has a specific dateand time assigned to it by either the browser or server.

An example is counting page views per day. The event count givesthe total number of page views loaded during the day, visit countis the number of visits (that downloaded at least one page view)during the day, and the visitor count gives the number of uniquevisitors (that downloaded at least one page view) that visited thesite during the day.

Some definitions

[Conversion]A visitor completing a target action.

Best practices

I 1: Tag all your pages.

I 2: Tags go last (customers come first :).

I 3: Tags should be inline.

I 4: What’s your unique page definition?

I 5: Use cookies intelligently (they are delicious).(Source attributes, Page attributes, User attributes)

I 6: Javascript wrapped links might be a issue.

I 7: Redirects, be aware of them.

I 8: Validate data is being captured correctly.

I 9: Don’t forget Flash, Flex, RIA, RSS, Videos etc.
