Спасибо за совет!
И прошу прощение за спам! :rolleyes: Я правда не нарошно!

Я по изложениям в школе всегда тройки получал, вы тоже нас извините.

Such a lot of data, so little information
IMAGINE you are an advertiser, you want to place your banners on the
most popular website, and you want to know how much to pay. Should you
go by unique users, duration, hits, click-through, impressions,
queries,
sessions, streams, page views or engagement?

Bob Ivins, who is in charge of all non-American business for comScore,
a
big web-measurement firm, says that the web produces data as ⌠a
fire-hose shoots water■, and that working out what those data mean is

rather like ⌠putting a straw into the fire hose to take a sip■.

Page views where the most widely used measure for much of the past
decade. It is the number of times a web browser calls up a web page on
a
given site. Page views became popular in the late 1990s, because they
were far superior to the existing measure of ⌠hits■, also known as
⌠file
requests■. "Hits" account every graphic on a page, as well as the
page
itself, counts as a hit. So that if a site owner put more graphics on
his pages, he would get more hits, even if everything else stayed the
same. ⌠We produced hits numbers because we could, not because it was
useful,■ says one old-timer in the industry.

Page views means something else entirely and are easy to comprehend by
analogy to the offline world to boot≈many advertisers are still used
to
counting pagination in magazines. Since then, everybody cares about
page
views. Strangely, page views at certain kinds of websites, especially
the more sophisticated sort, began to decline, even though the site
appeared otherwise healthy and popular.

The explanation has to do with ⌠Web 2.0■, and more specifically
with a
constituent technology called ⌠asynchronous JavaScript and XML■, or

AJAX. This is a method that lets web pages update parts of
themselves≈a
share-price ticker or an e-mail inbox, say≈without having to reload
and
redraw the rest of the page, resulting in web pages that behave less
like documents and more like pieces of software.

While a page view calls up a complete page to the browser, AJAX, or
"asynchronous JavaScript and XML" allows information to be sent piece
meal. The maps.google.com page is a great example of this Web 2.0
technology. Thus, a trip can be planned, or hours spent virtually
traveling the world would could as a single page view.

So, a better metric could be ⌠user sessions■, since that promises
to
count actual people, and show how many of them use a site. Its very
hard
to know how many actual people are visiting a site by user session. Is
it one over active individual going to the site 100 times a day or one
hundred users going once?

This could easily lead to overestimate of the number of users.
Inversely, several could watch a video at the same time, which would
leads to an underestimate of the number of users. User session does not

inform about these users.

Thus, AJAX enabled websites now favor ⌠Duration■ and ⌠time
spent■, which
suggests how long one or more people were interacting with a page,
which
gives clues at how ⌠engaged■, they were by the media on the page.
By
using these criteria, social-networking sites like, Facebook and
Stumbleupon suddenly look attractive.

The web's roots in information technology show clearly in these
consideration. The many ways to examine online presence puts the old
media to shame. Compare all these measures to the Neilson survey and
the
level of detail available to online advertisers. As the technology
advances, more sophisticated measures and methods of understanding
those
who consume the data.

As the holiday season is coming closer to its fever pitch, more
retailers are turning to online coupons to attract clients to their
online stores.

Looking through the internet, one can find many codes - on specialist
sites and reader forums, that can then be given to retailers for
discounts. For example, on the forums of Moneysavingexpert, members
post
details of the codes they are looking for. These codes produce
discounts
on specific items, others offer free postage and packing.

In some cases, the codes are given by individuals wishing to share a
bargain with fellow shoppers, while others are sent to these sites and
forums by the retailers themselves. Sendmediscounts.co.uk which was
founded by Nick Beeny five years ago and specializes only in codes sent

by retailers, says there has been an explosion in the number of offers
this year.
