Web traffic 

 Web traffic is the amount of data sent and received by visitors to a web site. It is a large portion of Internet traffic. This is determined by the number of visitors and the number of pages they visit. Sites monitor the incoming and outgoing traffic to see which parts or pages of their site are popular and if there are any apparent trends, such as one specific page being viewed mostly by people in a particular country. There are many ways to monitor this traffic and the gathered data is used to help structure sites, highlight security problems or indicate a potential lack of bandwidth - not all web traffic is welcome.

Some companies offer advertising schemes that, in return for increased web traffic (visitors), pay for screen space on the site. Sites also often aim to increase their web traffic through inclusion on search engines and through Search engine optimization.

Measuring web traffic 

Web traffic is measured to see the popularity of web sites and individual pages or sections within a site.

Web traffic can be analysed by viewing the traffic statistics found in the web server log file, an automatically-generated list of all the pages served. A hit is generated when any file is served. The page itself is considered a file, but images are also files, thus a page with 5 images could generate 6 hits (the 5 images and the page itself). A page view is generated when a visitor requests any page within the web site - a visitor will always generate at least one page view (the main page) but could generate many more.

Tracking applications external to the web site can record traffic by inserting a small piece of HTML code in every page of the web site.

Web traffic is also sometimes measured by packet sniffing and thus gaining random samples of traffic data from which to extrapolate information about web traffic as a whole across total Internet usage.

The following types of information are often collated when monitoring web traffic:

* The number of visitors.
* The average number of page views per visitor - a high number would indicate that the average visitors go deep inside the site, possibly because they like it or find it useful.
* Average visit duration - the total length of a user's visit. As a rule the more time they spend the more they're interested in your company and are more prone to contact.
* Average page duration - how long a page is viewed for. The more pages viewed, the better it is for your company.
* Domain classes - all levels of the IP Addressing information required to deliver Webpages and content.
* Busy times - the most popular viewing time of the site would show when would be the best time to do promotional campaigns and when would be the most ideal to perform maintenance
* Most requested pages - the most popular pages
* Most requested entry pages - the entry page is the first page viewed by a visitor and shows which are the pages most attracting visitors
* Most requested exit pages - the most requested exit pages could help find bad pages, broken links or the exit pages may have a popular external link
* Top paths - a path is the sequence of pages viewed by visitors from entry to exit, with the top paths identifying the way most customers go through the site
* Referrers; The host can track the (apparent) source of the links and determine which sites are generating the most traffic for a particular page.

Web sites like Alexa Internet produce traffic rankings and statistics based on those people who access the sites while using the Alexa toolbar. The difficulty with this is that it's not looking at the complete traffic picture for a site. Large sites usually hire the services of companies like Nielsen NetRatings, but their reports are available only by subscription.

Controlling web traffic

The amount of traffic seen by a web site is a measure of its popularity. By analysing the statistics of visitors it is possible to see shortcomings of the site and look to improve those areas. It is also possible to increase (or, in some cases decrease) the popularity of a site and the number of people that visit it. 

Limiting access 

It is sometimes important to protect some parts of a site by password, allowing only authorized people to visit particular sections or pages.

Some site administrators have chosen to block their page to specific traffic, such as by geographic location. The re-election campaign site for U.S. President George W. Bush (GeorgeWBush.com) was blocked to all internet users outside of the U.S. on 25 October 2004 after a reported attack on the site.[1]

It is also possible to limit access to a web server both based on the number of connections and by the bandwidth expended by each connection. On Apache HTTP servers, this is accomplished by the limitipconn module and others.

Increase web site traffic

Web traffic can be increased by placement of a site in search engines and purchase of advertising, including bulk e-mail, pop-up ads, and in-page advertisements. Web traffic can also be increased by purchasing non-internet based advertising.

If a web page is not listed in the first pages of any search, the odds of someone finding it diminishes greatly (especially if there is other competition on the first page). Very few people go past the first page, and the percentage that go to subsequent pages is substantially lower. Consequently, getting proper placement on search engines is as important as the web site itself.

Organic traffic

Web traffic which comes from unpaid listing at search engines or directories is commonly known as "organic" traffic. Organic traffic can be generated or increased by including the web site in directories, search engines, guides (such as yellow pages and restaurant guides) and award sites.

In most cases the best way to increase web traffic is to register it with the major search engines. Just registering does not guarantee traffic, as search engines work by "crawling" registered web sites. These crawling programs (crawlers) are also known as "spiders" or "robots". Crawlers start at the registered home page, and usually follow the hyperlinks it finds, to get to pages inside the web site (internal links). Crawlers start gathering information about those pages and storing it and indexing it in the search engine database. In every case, they index the page URL and the page title. In most cases they also index the web page header (meta tag) and a certain amount of the text of the page. Then, when a search engine user looks for a particular word or phrase, the search engine looks into the database and produces the results, usually sorted by relevance according to the search engine algorithms.

Usually, the top organic result gets most of the clicks from web users. According to some studies[citation needed], the top result gets between 5% and 10% of the clicks. Each subsequent result gets between 30% and 60% of the clicks of the previous one. This indicates that it is important to appear in the top results. There are some companies which specialize in search engine marketing. However, it is becoming common for webmasters to get approached by "boiler-room" companies with no real knowledge of how to get results. As opposed to pay-per-click, search engine marketing is usually paid monthly or annually, and most search engine companies cannot promise specific results for what is paid to them.

Because of the huge amount of information available on the web, crawlers might take days, weeks or months to complete review and index all the pages they find. Google, for example, as of the end of 2004 had indexed over eight billion pages. Even having hundreds or thousands of servers working on the spidering of pages, a complete reindexing takes its time. That is why some pages recently updated in certain web sites are not immediately found when doing searches on search engines.

Traffic

Traffic on roads may consist of pedestrians, ridden or herded animals, vehicles, streetcars and other conveyances, either singly or together, while using the public way for purposes of travel. Traffic laws are the laws which govern traffic and regulate vehicles, while rules of the road are both the laws and the informal rules that may have developed over time to facilitate the orderly and timely flow of traffic.

Organized traffic generally has well-established priorities, lanes, right-of-way, and traffic control at intersections.

Traffic is formally organized in many jurisdictions, with marked lanes, junctions, intersections, interchanges, traffic signals, or signs. Traffic is often classified by type: heavy motor vehicle (e.g., car, truck); other vehicle (e.g., moped, bicycle); and pedestrian. Different classes may share speed limits and easement, or may be segregated. Some jurisdictions may have very detailed and complex rules of the road while others rely more on drivers' common sense and willingness to cooperate.

Organization typically produces a better combination of travel safety and efficiency. Events which disrupt the flow and may cause traffic to degenerate into a disorganized mess include: road construction, collisions and debris in the roadway. On particularly busy freeways, a minor disruption may persist in a phenomenon known as traffic waves. A complete breakdown of organization may result in traffic jams and gridlock. Simulations of organized traffic frequently involve queuing theory, stochastic processes and equations of mathematical physics applied to traffic flow.

Rules of the road 

Rules of the road are the general practices and procedures that road users are required to follow. These rules usually apply to all road users, though they are of special importance to motorists and cyclists. These rules govern interactions between vehicles and with pedestrians. The basic traffic rules are defined by an international treaty under the authority of the United Nations, the 1968 Vienna Convention on Road Traffic. Not all countries are signatory to the convention and, even among signatories, local variations in practice may be found. There are also unwritten local rules of the road, which are generally understood by local drivers.

As a general rule, drivers are expected to avoid a collision with another vehicle and pedestrians, regardless of whether or not the applicable rules of the road allow them to be where they happen to be.

In addition to the rules applicable by default, traffic signs and traffic lights must be obeyed, and instructions may be given by a police officer, either routinely (on a busy crossing instead of traffic lights) or as road traffic control around a construction zone, accident, or other road disruption.

These rules should be distinguished from the mechanical procedures required to operate one's vehicle. See driving.

Organized traffic 

Priority (right of way) 

Vehicles often come into conflict with other vehicles and pedestrians because their intended courses of travel intersect, and thus interfere with each other's routes. The general principle that establishes who has the right to go first is called "right of way", or "priority". It establishes who has the right to use the conflicting part of the road and who has to wait until the other does so.

Signs, signals, markings and other features are often used to make priority explicit. Some signs, such as the stop sign, are nearly universal. When there are no signs or markings, different rules are observed depending on the location. These default priority rules differ between countries, and may even vary within countries. Trends toward uniformity are exemplified at an international level by the Vienna Convention on Road Signs and Signals, which prescribes standardized traffic control devices (signs, signals, and markings) for establishing the right of way where necessary.

Crosswalks (or pedestrian crossings) are common in populated areas, and may indicate that pedestrians have priority over vehicular traffic. In most modern cities, the traffic signal is used to establish the right of way on the busy roads. Its primary purpose is to give each road a duration of time in which its traffic may use the intersection in an organized way. The intervals of time assigned for each road may be adjusted to take into account factors such as difference in volume of traffic, the needs of pedestrians, or other traffic signals. Pedestrian crossings may be located near other traffic control devices; if they are not also regulated in some way, vehicles must give priority to them when in use. Traffic on a public road usually has priority over other traffic such as traffic emerging from private access; rail crossings and drawbridges are typical exceptions.

Uncontrolled traffic 

Uncontrolled traffic occurs in the absence of lane markings and traffic control signals. On roads without marked lanes, drivers tend to keep to the appropriate side if the road is wide enough. Drivers frequently overtake others. Obstructions are not uncommon.

Intersections have no signals or signage, and a particular road at a busy intersection may be dominant - that is, its traffic flows - until a break in traffic, at which time the dominance shifts to the other road where vehicles are queued. At the intersection of two perpendicular roads, a traffic jam may result if four vehicles face each other side-on.

Turning 

Drivers will often want to cease to travel a straight line and turn onto another road or onto private property. The vehicle's directional signals (blinkers) are often used as a way to announce one's intention to turn, thus alerting other drivers. The actual usage of blinkers varies greatly amongst countries, although its purpose should be the same in all countries: to indicate a driver's intention to depart from the current (and natural) flow of traffic well before the departure is executed (typically 3 seconds as a guideline).

This will usually mean that turning traffic will have to stop in order to wait for a breach to turn, and this might cause inconvenience for drivers that follow them but do not want to turn. This is why dedicated lanes and protected traffic signals for turning are sometimes provided. On busier intersections where a protected lane would be ineffective or cannot be built, turning may be entirely prohibited, and drivers will be required to "drive around the block" in order to accomplish the turn. Many cities employ this tactic quite often; in San Francisco, due to its common practice, making three right turns is known colloquially as a "San Francisco left turn". Likewise, as many intersections in Taipei City are too busy to allow direct left turns, signs often direct drivers to drive around the block to turn.

Turning rules are by no means universal. In New Zealand, for example, left turning traffic must give way to opposing "right turning" traffic, i.e., traffic turning into a driver's path (unless there are multiple lanes to turn into).

On roads with multiple lanes, turning traffic is generally expected to move to the lane closest to the direction they wish to turn. For example, traffic intending to turn right will usually move to the rightmost lane before the intersection. Likewise, left-turning two rightmost lanes will be of authority; for example, in Brazil and elsewhere it is common for drivers to observe (and trust) the turn signals used by other drivers in order to make turns from other lanes. For example if several vehicles on the right lane are all turning right, a vehicle may come from the next-to-right lane and turn right as well, doing so in parallel with the other right-turning vehicles.
