Bounce rate

Bounce rate

Bounce rate (sometimes confused with exit rate)[1] is an Internet marketing term used in web traffic analysis. It represents the percentage of visitors who enter the site and then leave ("bounce") rather than continuing on to view other pages within the same site.
Bounce rate is a measure of the effectiveness of a website in encouraging visitors to continue with their visit. It is expressed as a percentage and represents the proportion of visits that end on the first page of the website that the visitor sees.[2]

Purpose

Bounce rates can be used to help determine the effectiveness or performance of an entry page at generating the interest of visitors. An entry page with a low bounce rate means that the page effectively causes visitors to view more pages and continue on deeper into the web site.[3][2]
High bounce rates typically indicate that the website isn’t doing a good job of attracting the continued interest of visitors.[2]
Interpretation of the bounce rate measure should be relevant to a website's business objectives and definitions of conversion, as having a high bounce rate is not always a sign of poor performance. On sites where an objective can be met without viewing more than one page, for example on websites sharing specific knowledge on some subject (dictionary entry, specific recipe), the bounce rate would not be as meaningful for determining conversion success.[4] In contrast, the bounce rate of an e-commerce site could be interpreted in correlation with the purchase conversion rate, providing the bounces are considered representative of visits where no purchase was made.[citation needed]

Construction

A bounce occurs when a web site visitor only views a single page on a website, that is, the visitor leaves a site without visiting any other pages before a specified session-timeout occurs. There is no industry standard minimum or maximum time by which a visitor must leave in order for a bounce to occur. Rather, this is determined by the session timeout of the analytics tracking software.
R_b = \frac{T_v}{T_e}
where
  • Rb = Bounce rate
  • Tv = Total number of visitors viewing one page only
  • Te = Total entries to page[2]
A visitor may bounce by:
  • Clicking on a link to a page on a different web site
  • Closing an open window or tab
  • Typing a new URL
  • Clicking the "Back" button to leave the site
  • Session timeout[2]
There are two exceptions: 1) You have a one page website 2) Your offline value proposition is so compelling that people would see just one single webpage and get all the information they need and leave.
Updated more accurate measure of bounce rate is:
Bounce Rate = "Total number of visits viewing one page" divided by "Total number of visits greater than or equal to the average variable page load speed".
  • Rb = Bounce rate
  • Tv = Total number of visits viewing one page only
  • Te = Total entries to page
  • Ps = Average variable page load speed
R_b = \frac{T_v}{T_e} \leq P_s
A commonly used session timeout value is 30 minutes.[5] In this case, if a visitor views a page, doesn't look at another page, and leaves his or her browser idle for longer than 30 minutes, they will register as a bounce. If the visitor continues to navigate after this delay, a new session will occur.
The bounce rate for a single page is the number of visitors who enter the site at a page and leave within the specified timeout period without viewing another page, divided by the total number of visitors who entered the site at that page. In contrast, the bounce rate for a web site is the number of web site visitors who visit only a single page of a web site per session divided by the total number of web site visits.

Caveats

While site-wide bounce rate can be a useful metric for sites with well-defined conversion steps requiring multiple page views, it may be of questionable value for sites where visitors are likely to find what they are looking for on the entry page. This type of behavior is common on web portals and referential content sites.[6] For example, a visitor looking for the definition of a particular word may enter an online dictionary site on that word's definition page. Similarly, a visitor who wants to read about a specific news story may enter a news site on an article written for that story. These example entry pages could have a bounce rate above 80% (thereby increasing the site-wide average), however they may still be considered successful.

Bandwidth (computing)

From Wikipedia, the free encyclopedia
This article is about the concept in computing and networking. For use in signal and wireless communications, seeBandwidth (signal processing). For other uses, see Bandwidth (disambiguation).
In computing, bandwidth is the bit-rate of available or consumed information capacity expressed typically in metric multiples of bits per second. Variously, bandwidth may be characterized as network bandwidth,[1] data bandwidth,[2] ordigital bandwidth.[3][4]
This definition of bandwidth is in contrast to the field of signal processingwireless communicationsmodem data transmissiondigital communications, and electronics, in which bandwidth is used to refer to analog signal bandwidthmeasured in hertz, meaning the frequency range between lowest and highest attainable frequency while meeting a well-defined impairment level in signal power.
However, the actual bit rate that can be achieved depends not only on the signal bandwidth, but also on the noise on the channel.

Network bandwidth capacity[edit]

The term bandwidth sometimes defines the net bit rate (aka. peak bit rateinformation rate, or physical layer useful bit rate), channel capacity, or the maximum throughput of a logical or physical communication path in a digital communication system. For example, bandwidth tests measure the maximum throughput of a computer network. The maximum rate that can be sustained on a link are limited by the Shannon-Hartley channel capacity for these communication systems, which is dependent on the bandwidth in hertz and the noise on the channel.

Network bandwidth consumption[edit]

Bandwidth in bit/s may also refer to consumed bandwidth, corresponding to achieved throughput or goodput, i.e., the average rate of successful data transfer through a communication path. This sense applies to concepts and technologies such as bandwidth shapingbandwidth managementbandwidth throttlingbandwidth capbandwidth allocation (for example bandwidth allocation protocol and dynamic bandwidth allocation), etc. A bit stream's bandwidth is proportional to the average consumed signal bandwidth in Hertz (the average spectral bandwidth of the analog signal representing the bit stream) during a studied time interval.
Channel bandwidth may be confused with useful data throughput (or goodput). For example, a channel with x bps may not necessarily transmit data at x rate, since protocols, encryption, and other factors can add appreciable overhead. For instance, a lot of internet traffic uses the transmission control protocol (TCP), which requires a three-way handshake for each transaction. Although in many modern implementations the protocol is efficient, it does add significant overhead compared to simpler protocols. Also, data packets may be lost, which further reduces the useful data throughput. In general, for any effective digital communication, a framing protocol is needed; overhead and effective throughput depends on implementation. Useful throughput is less than or equal to the actual channel capacity plus implementation overhead.

Asymptotic bandwidth[edit]

The asymptotic bandwidth (formally asymptotic throughput) for a network is the measure of maximum throughput for agreedy source, for example when the message size (the number of packets per second from a source) approaches infinity.[5]
Asymptotic bandwidths are usually estimated by sending a number of very large messages through the network, measuring the end-to-end throughput. As other bandwidths, the asymptotic bandwidth is measured in multiples of bits per seconds

Multimedia bandwidth[edit]

Digital bandwidth may also refer to: multimedia bit rate or average bitrate after multimedia data compression (source coding), defined as the total amount of data divided by the playback time.

Bandwidth in web hosting[edit]

In Web hosting service, the term bandwidth is often[citation needed] incorrectly used to describe the amount of data transferred to or from the website or server within a prescribed period of time, for example bandwidth consumption accumulated over a month measured in gigabytes per month. The more accurate phrase used for this meaning of a maximum amount of data transfer each month or given period is monthly data transfer.
A similar situation can occur for end user ISPs as well, especially where network capacity is limited (for example in areas with under developed internet connectivity and on wireless networks).
