A backlink for a given web resource is a link from some other website (the referrer) to that web resource (the referent).[1] A web resource may be (for example) a website, web page, or web directory.[1]

A backlink is a reference comparable to a citation. The quantity, quality, and relevance of backlinks for a web page are among the factors that search engines like Google evaluate in order to estimate how important the page is.[2][3] PageRank calculates the score for each web page based on how all the web pages are connected among themselves, and is one of the variables that Google Search uses to determine how high a web page should go in search results.[4] This weighting of backlinks is analogous to citation analysis of books, scholarly papers, and academic journals.[1][3] A Topical PageRank has been researched and implemented as well, which gives more weight to backlinks coming from the page of a same topic as a target page. [5]

Some other words for backlink are incoming link, inbound link, inlink, inward link, and citation.[1]


Backlinks are offered in Wikis, but usually only within the bounds of the Wiki itself and enabled by the database backend. MediaWiki, specifically offers the "What links here" tool, some older Wikis, especially the first WikiWikiWeb, had the backlink functionality exposed in the page title.

Backlinks and search engines

Search engines often use the number of backlinks that a website has as one of the most important factors for determining that website's search engine ranking, popularity and importance. Google's description of its PageRank system, for instance, notes that "Google interprets a link from page A to page B as a vote, by page A, for page B."[6] Knowledge of this form of search engine rankings has fueled a portion of the SEO industry commonly termed linkspam, where a company attempts to place as many inbound links as possible to their site regardless of the context of the originating site. The significance of search engine rankings is pretty high, and it is regarded as a crucial parameter in online business and the conversion rate of visitors to any website, particularly when it comes to online shopping. Blog commenting, guest blogging, article submission, press release distribution, social media engagements, and forum posting can be used to increase backlinks.

Websites often employ SEO techniques to increase the number of backlinks pointing to their website. Some methods are free for use by everyone whereas some methods, like linkbaiting, require quite a bit of planning and marketing to work. There are also paid techniques to increase the number of backlinks to a target site. For example, private blog networks can be used to purchase backlinks.

There are several factors that determine the value of a backlink. Backlinks from authoritative sites on a given topic are highly valuable. If both sites and pages have content geared toward the topic, the backlink is considered relevant and believed to have strong influence on the search engine rankings of the web page granted the backlink. A backlink represents a favorable 'editorial vote' for the receiving webpage from another granting webpage. Another important factor is the anchor text of the backlink. Anchor text is the descriptive labeling of the hyperlink as it appears on a web page. Search engine bots (i.e., spiders, crawlers, etc.) examine the anchor text to evaluate how relevant it is to the content on a webpage. Anchor text and webpage content congruency are highly weighted in search engine results page (SERP) rankings of a webpage with respect to any given keyword query by a search engine user.

Changes to the algorithms that produce search engine rankings can place a heightened focus on relevance to a particular topic. While some backlinks might be from sources containing highly valuable metrics, they could also be unrelated to the consumer's query or interest. An example of this would be a link from a popular shoe blog (with valuable metrics) to a site selling vintage pencil sharpeners. While the link appears valuable, it provides little to the consumer in terms of relevance.

Change impact analysis

Change impact analysis (IA) is defined by Bohner and Arnold as "identifying the potential consequences of a change, or estimating what needs to be modified to accomplish a change", and they focus on IA in terms of scoping changes within the details of a design. In contrast, Pfleeger and Atlee focus on the risks associated with changes and state that IA is: "the evaluation of the many risks associated with the change, including estimates of the effects on resources, effort, and schedule". Both the design details and risks associated with modifications are critical to performing IA within the change management processes. A technical colloquial term is also mentioned sometimes in this context, dependency hell.

Competitor backlinking

Competitor backlinking is a search engine optimization strategy that involves analyzing the backlinks of competing websites within a vertical search. The outcome of this activity is designed to increase organic search engine rankings and to gain an understanding of the link building strategies used by business competitors.By analyzing the backlinks to competitor websites, it is possible to gain a benchmark on the number of links and the quality of links that is required for high search engine rankings. Another possible outcome of competitive backlinking is the identification of the type of websites that are inclined to link to a specific type of website.

Cross-country eliminator

The Cross-country eliminator (XCE) is a new mountain bike race format in which four riders compete against each other in each heat, similar to Four-cross.

The two fastest riders get to the next round while the two slower riders are eliminated from the race.

The format differs from the classic cross-country race both in its sprint character and the separation of the race into heats.

The 500m - 1000m short track itself is similar to XC tracks, going both uphill and downhill.


DrinkExchange was a monthly social and business networking party started in San Francisco, California during the dot com bubble.The event was started in February, 1997 by Ali Partovi, co-founder of the Internet firm LinkExchange, and his roommate-coworkers Alan Shusterman and Mike Bayle, who were initially looking to find ways to improve their social life. The format was humorously based on LinkExchange's early ad exchange model (though not formally affiliated with the company), by which web publishers could trade two outgoing "clicks" on banner ads placed on their site for one visitor backlink from other publishers. At the events, participants were encouraged to buy two alcoholic drinks, and give one to a fellow guest.Invitations to the initial event, held at the local Gordon Biersch brewery, were in the form of a mock product announcement press release from LinkExchange, which ended up becoming a local viral email phenomenon and attracting seventy guests. Later events drew more than one thousand participants each, included corporate sponsorships, and eventually spread to Tokyo, Sydney, London, Hong Kong, San Diego, and Washington, DC. The parties continued until the "dot com crash" of 2001.

Keyword stuffing

Keyword stuffing is a search engine optimization (SEO) technique, considered webspam or spamdexing, in which keywords are loaded into a web page's meta tags, visible content, or backlink anchor text in an attempt to gain an unfair rank advantage in search engines. Keyword stuffing may lead to a website being banned or penalized on major search engines either temporarily or permanently. The repetition of words in meta tags may explain why many search engines no longer use these tags.

Many major search engines have implemented algorithms that recognize keyword stuffing, and reduce or eliminate any unfair search advantage that the tactic may have been intended to gain, and oftentimes they will also penalize, demote or remove websites from their indexes that implement keyword stuffing.

Changes and algorithms specifically intended to penalize or ban sites using keyword stuffing include the Google Florida update (November 2003) Google Panda (February 2011) Google Hummingbird (August 2013) and Bing's September 2014 update.


Kneissl is a manufacturer of handmade skis, biking and tennis equipment and apparel, based in Kufstein, Tyrol, Austria.

Link bidding

Link bidding is a form of Internet marketing where a website owner bids on other websites to post a backlink to a website.

A link bidding directory offers webmasters a way to gain exposure for their sites. Websites being bid on are often grouped into categories (e.g., entertainment, finance). The position/rank for such websites is determined by their frequency of bids, where the highest-ranking websites have the highest number of bids.

Link farm

On the World Wide Web, a link farm is any group of web sites that all hyperlink to every other site in the group. In graph theoretic terms, a link farm is a clique. Although some link farms can be created by hand, most are created through automated programs and services. A link farm is a form of spamming the index of a web search engine (sometimes called spamdexing). Other link exchange systems are designed to allow individual websites to selectively exchange links with other relevant websites and are not considered a form of spamdexing.

Search engines require ways to confirm page relevancy. A known method is to examine for one-way links coming directly from relevant websites. The process of building links should not be confused with being listed on link farms, as the latter requires reciprocal return links, which often renders the overall backlink advantage useless. This is due to oscillation, causing confusion over which is the vendor site and which is the promoting site.

Spam blog

A spam blog, also known as an auto blog or the neologism splog, is a blog which the author uses to promote affiliated websites, to increase the search engine rankings of associated sites or to simply sell links/ads.

The purpose of a splog can be to increase the PageRank or backlink portfolio of affiliate websites, to artificially inflate paid ad impressions from visitors (see made for AdSense or MFA-blogs), and/or use the blog as a link outlet to sell links or get new sites indexed. Spam blogs are usually a type of scraper site, where content is often either inauthentic text or merely stolen (see blog scraping) from other websites. These blogs usually contain a high number of links to sites associated with the splog creator which are often disreputable or otherwise useless websites.

There is frequent confusion between the terms "splog" and "spam in blogs". Splogs are blogs where the articles are fake, and are only created for search engine spamming. To spam in blogs, conversely, is to include random comments on the blogs of innocent bystanders, in which spammers take advantage of a site's ability to allow visitors to post comments that may include links. In fact, one of the earliest uses of the term "splog" referred to the latter.This is used often in conjunction with other spamming techniques, including spings.

Web indexing

Web indexing (or Internet indexing) refers to various methods for indexing the contents of a website or of the Internet as a whole. Individual websites or intranets may use a back-of-the-book index, while search engines usually use keywords and metadata to provide a more useful vocabulary for Internet or onsite searching. With the increase in the number of periodicals that have articles online, web indexing is also becoming important for periodical websites.Back-of-the-book-style web indexes may be called "web site A-Z indexes". The implication with "A-Z" is that there is an alphabetical browse view or interface. This interface differs from that of a browse through layers of hierarchical categories (also known as a taxonomy) which are not necessarily alphabetical, but are also found on some web sites. Although an A-Z index could be used to index multiple sites, rather than the multiple pages of a single site, this is unusual.

Metadata web indexing involves assigning keywords or phrases to web pages or web sites within a metadata tag (or "meta-tag") field, so that the web page or web site can be retrieved with a search engine that is customized to search the keywords field. This may or may not involve using keywords restricted to a controlled vocabulary list. This method is commonly used by search engine indexing.

Yahoo! Site Explorer

Yahoo! Site Explorer (YSE) was a Yahoo! service which allowed users to view information on websites in Yahoo!'s search index. The service was closed on November 21, 2011 and merged with Bing Webmaster Tools, a tool similar to Google Search Console (previously Google Webmaster Tools). In particular, it was useful for finding information on backlinks pointing to a given webpage or domain because YSE offered full, timely backlink reports for any site. After merging with Bing Webmaster Tools, the service only offers full backlink reports to sites owned by the webmaster. Reports for sites not owned by the webmaster are limited to 1,000 links.Webmasters who added a special authentication code to their websites were also allowed to:

See extra information on their sites

Submit Sitemaps

Submit up to 20 URL removal requests for their domains to Yahoo!.

Rewrite dynamic URLs from their site by either removing a dynamic parameter or by using a default value for a parameter.

Submit feeds for Yahoo Search Monkey
