Link exchange
An alternative to the automated linking above is a link exchange forum, in which members will advertise the sites that they want to get links to, and will in turn offer reciprocal or
three way links back to the sites that link to them. The links generated through such services are subject to editorial review.
One way link
One way link is a term used among webmasters for link building methods. It is a hyperlink that points to a website without any reciprocal link; thus the link goes "one way" in direction.
It is suspected by many industry consultants that this type of link would be considered more natural in the eyes of search engines.
An effective way to build this type of one way linking is by distributing articles through content sites and article directories. These articles generally contain an About The Author box
that contains a one-way link back to the author's URL. When publishers use these articles, those one-way links help authors increase their page rank.
Multiway linking
Multiway linking is a technique used for website promotion whereby websites may create similar one way links that each involve 3 or more partner sites. This provides each website with a
one way non-reciprocal link. This technique has evolved from reciprocal linking, which is a link created between only 2 websites. According to Google and Yahoo, the latest search algorithms have evolved to
hold less favour towards websites that a contain a high percentage of reciprocated links, and a higher favour towards websites that maintain a high level of incoming non-reciprocated (one-way) links.
The term multiway simply refers to the fact that the link exchange is between 3 or more websites, however each link is singular by only pointing to one other website. Other means of
linking that may increase your web presence may also include other indirect methods such as loading images, videos, content or RSS feeds from a third partners website.
Link campaign
Link campaigns are a form of online marketing and SEO. A business seeking to increase the number of visitors to its web site can ask its strategic partners, professional organizations,
chambers of commerce, suppliers, and customers to add links from their web sites. A link campaign may involve mutual links back and forth between related sites, but it doesn't have to require the reciprocation
of links.
Incestuous linking
Incestuous linking is an SEO strategy used by a webmaster to promote a collection of their own web sites, or those of close friends.
Due to the domination of the search engine market by Google, and its underlying PageRank technology, sites are deemed to be more important if they have large numbers of inbound links. If those
inbound links are also from highly ranked web sites, they will boost the web site further. With the takeup of blogging and social networking sites such as MySpace, this has resulted in lots of web sites that
are inter-linked and can artificially improve the ranking of a web site without merit, i.e. without valuable, or unique content.
When the sites are not directly owned, this is referred to as a web clique.
Overlinking
Overlinking in a webpage or another hyperlinked text is the characteristic of having too many hyperlinks.
It is characterized by:
-
A large proportion of the words in each sentence being rendered as links.
-
Links that have little information content, such as linking on specific years like 1995, or unnecessary linking of common words used in the common way, for which the reader can be expected to
understand the word's full meaning in context, without any hyperlink help.
-
A link for any single term is excessively repeated in the same article. "Excessive" is usually more than one link for the same term in a line or a paragraph, since in this case one or more
duplicate links will almost certainly then appear needlessly on the viewer's screen.
Underlinking
The opposites of overlinking are null linking and underlinking, which are phenomena in which hyperlinks are reduced to such a degree as to remove all pointers to a likely-needed
context of an unusual term, in the text-area where the term occurs. Underlinking results whenever a reader encounters an odd term in an article (perhaps not even for the first time), and wants to briefly
browse more deeply at that point, but he or she cannot without an extensive search of the article for a (possibly non-existent) instance of the linked term.
Link doping
Link doping refers to the practice and effects of embedding a large number of gratuitous hyperlinks on a website, in exchange for reciprocal links. Mainly used when describing blogs,
link doping usually implies that a person hyperlinks to sites he or she has never visited, in return for a place on the website's blogroll, for the sole purpose of inflating the apparent popularity of his or
her website. Since the search algorithms of many web directories and search engines rely on the number of hyperlinks to a website to determine its importance or influence, link doping can result in a high
placement or ranking for the offending website.
Originally used in an essay published in Sobriquet Magazine and on Blogcritics.org, link doping has been confused with the related practice of excessive hyperlinking, also known as "link
whoring". While the two phrases may be used interchangeably to describe gratuitous linking, link doping carries the additional connotation of deliberately striving to attain a certain level of success for
one's website without having earned it through hard work (as an average athlete on steroids might perform better than a naturally gifted athlete not on performance-enhancing drugs).
Free for All linking
A Free For All (FFA) link page is a web page set up ostensibly to improve the search engine placement of a particular web site. Webmasters typically will use software to place a link to
their site on hundreds of FFA sites, hoping that the resulting incoming links will increase the ranking of their site in search engines. Experts in SEO techniques do not place much value on FFAs. First, most
FFAs only maintain a small number of links for a short time, too short for most search engines to pick up. Second, the high "human" traffic to FFA sites is almost completely other webmasters visiting the site
to place their own links manually. Finally, search engine algorithms count more than link numbers, they also check relevancy which the unrelated links on FFA sites do not have. Another drawback to FFAs is the
amount of e-mail spam webmasters will receive from members of the FFA. Using an FFA can be considered a form of spamdexing.
Link popularity
Link popularity is a measure of the quantity and quality of other web sites that link to a specific site on the World Wide Web. It is an example of the move by search engines towards
off-the-page-criteria to determine quality content. In theory, off-the-page-criteria adds the aspect of impartiality to search engine rankings. Link popularity plays an important role in the visibility of a
web site among the top of the search results. Indeed, some search engines require at least one or more links coming to a web site, otherwise they will drop it from their index.
Search engines such as Google use a special link analysis system to rank web pages. Citations from other WWW authors help to define a site's reputation. The philosophy of link popularity is
that important sites will attract many links. Content-poor sites will have difficulty attracting any links. Link popularity assumes that not all incoming links are equal, as an inbound link from a major
directory carries more weight than an inbound link from an obscure personal home page. In other words, the quality of incoming links counts more than sheer numbers of them.
