Ad blocking - Wikipedia. For the extension by Eyeo Gmb. H, see Adblock Plus. For the extension by Michael Gundlach, see Ad. Block. Ad blocking or ad filtering is a type of software (or less commonly, a computer hardware device), that can remove or alter advertising content from a webpage, website, or a mobile app.

Ad blockers are available for a range of computer platforms, including desktop and laptop computers, tablet computers and smartphones. A variety of methods have been used for blocking advertisements. Some have taken counter- measures against users who block ads on the sites they visit, for example Forbes. All browsers offer some ways to remove or alter advertisements: either by targeting technologies that are used to deliver ads (such as embedded content delivered through browser plug- ins or via HTML5), targeting URLs that are the source of ads, or targeting behaviors characteristic to ads (such as the use of HTML5 autoplay of both audio and video). Reasons for blocking ads.

Publishers claim that the prevalent use of ad blocking software and devices could adversely affect website owner revenue and thus in turn lower the availability of free content on websites. Benefits. Blocking ads can also save substantial amounts of electrical energy and lower users' power bills. Advertisements are very carefully crafted to target weaknesses in human psychology.

Irritated users might make a conscious effort to avoid the goods and services of firms which are using annoying . Any ad that appears on a website exerts a toll on the user's . Time Saver Standards For Building Types 10Th Edition Pdf more.

A user who is strongly focused on reading solely the content that they are seeking, likely has no desire to be diverted by advertisements that seek to sell unneeded or unwanted goods and services. If a user's personal time is worth one dollar per minute, and if unsolicited advertising adds an extra minute to the time that the user requires for reading the webpage (i. The problem of lost time can rapidly spiral out of control if malware accompanies the ads.

Streaming audio and video, even if they are not presented to the user interface, can rapidly consume gigabytes of transfer especially on a faster 4. G connection. Since users without a data plan often pay by the megabyte, the cost of tolerating ads can be quite high. Even fixed connections are often subject to usage limits, especially the faster connections (1. Mbit/s and up) which can quickly saturate a network if filled by streaming media.

In March 2. 01. 6, the Internet Advertising Bureau reported that UK adblocking was already at 2. Another common product placement is for an automotive manufacturer to give free cars to the producers of a TV show, in return for the show's producer depicting characters using these vehicles during the show. Methods. This can be done in most browsers easily and also improves security and privacy.

This crude technological method is refined by numerous browser extensions. Every Internet browser handles this task differently, but, in general, one alters the options, preferences or application extensions to filter specific media types. An additional add- on is usually required to differentiate between ads and non- ads using the same technology, or between wanted and unwanted ads or behaviors.

The more advanced ad blocking filter software allow fine- grained control of advertisements through features such as blacklists, whitelists, and regular expression filters. Certain security features also have the effect of disabling some ads. Some antivirus software can act as an ad blocker. Filtering by intermediaries such as ISP providers or national governments is increasingly common.

Browser integration. Current versions of Konqueror. Content filtering can be added to Firefox, Chromium- based browsers, Opera, Safari and other browsers with extensions such as Ad. Block, Adblock Plus and u.

H) is included in the freeware browser Maxthon from the People's Republic of China by default. In 2. 01. 7, Google has announced their plan for creating an in- built ad blocker for Chrome browser. Google has many reasons to create its own ad blocker, particularly given the growing use of third party ad blockers. A traditional solution is to customize an HTTP proxy (or web proxy) to filter content. These programs work by caching and filtering content before it is displayed in a user's browser.

This provides an opportunity to remove not only ads but also content which may be offensive, inappropriate, or even malicious (Drive- by download). Popular proxy software which blocks content effectively include Netnanny, Privoxy, Squid, and some content- control software.

The main advantage of the method is freedom from implementation limitations (browser, working techniques) and centralization of control (the proxy can be used by many users). Proxies are very good at filtering ads, but they have several limitations compared to browser based solutions. For proxies, it is difficult to filter Transport Layer Security (SSL) (https: //) traffic and full webpage context is not available to the filter. As well, proxies find it difficult to filter Java. Script- generated ad content.

Hosts file and DNS manipulation. This configuration, for historical reasons, is stored in a flat text file that by default contains very few hostnames and their associated IP addresses. Editing this hosts file is simple and effective because most DNS clients will read the local hosts file before querying a remote DNS server. Storing black- hole entries in the hosts file prevents the browser from accessing an ad server by manipulating the name resolution of the ad server to a local or nonexistent IP address (1.

IPv. 4 addresses). While simple to implement, these methods are also very easy for advertisers to circumvent.

One method to circumvent this form of ad filtering is to load ads from servers with hard coded IP addresses, thus skipping name resolution altogether. Another method to evade this form of filtering is to load the advertisements from a server which also serves the main content; blocking name resolution of this server would also block the useful content of the site. Using a DNS sinkhole by manipulating the hosts file exploits the fact that most operating systems store a file with IP address, domain name pairs which is consulted by most browsers before using a DNS server to look up a domain name.

By assigning the loopback address to each known ad server, the user directs traffic intended to reach each ad server to the local machine or to a virtual black hole of /dev/null or bit bucket. DNS cache. On most operating systems the domain name resolution always goes via DNS cache. By changing records within the cache or preventing records from entering the cache, programs are allowed or prevented from accessing domain names. The external programs monitor internal DNS cache and import DNS records from a file. Thus its records take precedence over DNS server queries. Unlike the method of modifying a Hosts file, this method is more flexible as it uses more comprehensive data available from DNS cache records. DNS filtering. A DNS firewall, such as Verigio DNS Firewall, can also block access to IP addresses for names not resolved via DNS.

Thus prevent display of advertisements from servers accessed directly using their IP addresses. China runs its own root DNS and the EU has considered the same. Google has required their Google Public DNS be used for some applications on its Android devices. Accordingly, DNS addresses / domains used for advertising may be extremely vulnerable to a broad form of ad substitution whereby a domain that serves ads is entirely swapped out with one serving more local ads to some subset of users.

This is especially likely in countries, notably Russia, India and China, where advertisers often refuse to pay for clicks or page views.
