The phrase "academic search engines" is the anchor text in the hyperlink that the cursor is pointing to.

The anchor text, link label or link text is the visible, clickable text in an HTML hyperlink. The term "anchor" was used in older versions of the HTML specification [1] for what is currently referred to as the a element, or <a>. [2] The HTML specification does not have a specific term for anchor text, but refers to it as "text that the a element wraps around". In XML terms (since HTML is XML), the anchor text is the content of the element, provided that the content is text. [3]

Contents

Usually, web search engines analyze anchor text from hyperlinks on web pages. The words contained in the anchor text can determine the ranking that the page will receive from search engines. Other services apply the basic principles of anchor text analysis as well. For instance, academic search engines may use citation context to classify academic articles, [4] and anchor text from documents linked in mind maps may be used too. [5]

Overview

Anchor text usually gives the user relevant descriptive or contextual information about the content of the link's destination. The anchor text may or may not be related to the actual text of the URL of the link. For example, a hyperlink to the English-language Wikipedia's homepage might take this form:

<a href="http://en.wikipedia.org/wiki/Main_Page">Wikipedia</a>

"Wikipedia" is the anchor text in this example. The URL it points to is http://en.wikipedia.org/wiki/Main_Page. The entire hyperlink appears on a web page as Wikipedia.

Search engine algorithms

Anchor text is weighted (ranked) highly in search engine algorithms, because the linked text is usually relevant to the landing page. The objective of search engines is to provide highly relevant search results; this is where anchor text helps, as the tendency was, more often than not, to hyperlink words relevant to the landing page. Anchor text can also serve the purpose of directing the user to internal pages on the site, which can also help to rank the website higher in the search rankings. [6]

Webmasters may use anchor text to procure high results in search engine results pages. Google's Webmaster Tools facilitate this optimization by letting website owners view the most common words in anchor text linking to their site. [7] In the past, Google bombing was possible through anchor text manipulation; however, in January 2007, Google announced it had updated its algorithm to minimize the impact of Google bombs, which refers to a prank where people attempt to cause someone else's site to rank for an obscure or meaningless query. [8]

In April 2012, Google announced in its March "Penguin" update that it would be changing the way it handled anchor text, implying that anchor text would no longer be as important an element for their ranking metrics. [9] Moving forward, Google would be paying more attention to a diversified link profile which has a mix of anchor text and other types of links. . [10]

However a 2016 study of anchor text influence across 16,000 keywords found that presence of exact and partial match anchor links continues to have a strong correlation with Google rankings.

August 2016 study conducted by Moz, found that Exact and partial match domains can be affected by over optimization penalty since Google considers domain Brand and naked URL links as Exact match. [11]

Terminology

There are different classifications of anchor text that are used within the search engine optimization community such as the following:

Exact match
an anchor that is used with a keyword that mirrors the page that is being linked to. Example: "search engine optimization" is an exact match anchor because it's linking to a page about "search engine optimization".
Partial match
an anchor that is used with a keyword and a variation that mirrors the page that is being linked to. Example: "different search engine optimization techniques" is a partial match anchor when it's linking to a page about "search engine optimization".
Branded
a brand that is used as the anchor. "Wikipedia" is a branded anchor text.
Naked link
a URL that is used as an anchor. "www.wikipedia.com" is a naked link anchor.
Generic
a generic word or phrase that is used as the anchor. "Click here" is a generic anchor recommended against on grounds of usability and accessibility. [12] [13] Other variations may include "go here", "visit this website", etc.
Images
whenever an image is linked, Google will use the "alt" attribute as the anchor text.
Empty
whenever an image is linked, and the "alt" attribute is empty.
Latent semantic indexing
Latent semantic indexing (LSI) is a method used by Google to determine similar keywords.

Search engine optimization (SEO) is the process of improving the quality and quantity of website traffic to a website or a web page from search engines. SEO targets unpaid traffic rather than direct traffic or paid traffic. Unpaid traffic may originate from different kinds of searches, including image search, video search, academic search, news search, and industry-specific vertical search engines.

<span class="mw-page-title-main">Link farm</span> Group of websites that link to each other

On the World Wide Web, a link farm is any group of websites that all hyperlink to other sites in the group for the purpose of increasing SEO rankings. 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. 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.

A backlink is a link from some other website to that web resource. A web resource may be a website, web page, or web directory.

In computer hypertext, a URI fragment is a string of characters that refers to a resource that is subordinate to another, primary resource. The primary resource is identified by a Uniform Resource Identifier (URI), and the fragment identifier points to the subordinate resource.

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 temporarily or permanently banned or penalized on major search engines. The repetition of words in meta tags may explain why many search engines no longer use these tags. Nowadays, search engines focus more on the content that is unique, comprehensive, relevant, and helpful that overall makes the quality better which makes keyword stuffing useless, but it is still practiced by many webmasters.

Search engine marketing (SEM) is a form of Internet marketing that involves the promotion of websites by increasing their visibility in search engine results pages (SERPs) primarily through paid advertising. SEM may incorporate search engine optimization (SEO), which adjusts or rewrites website content and site architecture to achieve a higher ranking in search engine results pages to enhance pay per click (PPC) listings and increase the Call to action (CTA) on the website.

Sitemaps is a protocol in XML format meant for a webmaster to inform search engines about URLs on a website that are available for web crawling. It allows webmasters to include additional information about each URL: when it was last updated, how often it changes, and how important it is in relation to other URLs of the site. This allows search engines to crawl the site more efficiently and to find URLs that may be isolated from the rest of the site's content. The Sitemaps protocol is a URL inclusion protocol and complements robots.txt, a URL exclusion protocol.

An SEO contest is a prize activity that challenges search engine optimization (SEO) practitioners to achieve high ranking under major search engines such as Google, Yahoo, and MSN using certain keyword(s). This type of contest is controversial because it often leads to massive amounts of link spamming as participants try to boost the rankings of their pages by any means available. The SEO competitors hold the activity without the promotion of a product or service in mind, or they may organize a contest in order to market something on the Internet. Participants can showcase their skills and potentially discover and share new techniques for promoting websites.

nofollow is a setting on a web page hyperlink that directs search engines not to use the link for page ranking calculations. It is specified in the page as a type of link relation; that is: <a rel="nofollow" ...>. Because search engines often calculate a site's importance according to the number of hyperlinks from other sites, the nofollow setting allows website authors to indicate that the presence of a link is not an endorsement of the target site's importance.

<span class="mw-page-title-main">Search engine</span> Software system for finding relevant information on the Web

A search engine is a software system that provides hyperlinks to web pages and other relevant information on the Web in response to a user's query. The user inputs a query within a web browser or a mobile app, and the search results are often a list of hyperlinks, accompanied by textual summaries and images. Users also have the option of limiting the search to a specific type of results, such as images, videos, or news.

A search engine results page (SERP) is a webpage that is displayed by a search engine in response to a query by a user. The main component of a SERP is the listing of results that are returned by the search engine in response to a keyword query.

Search engine indexing is the collecting, parsing, and storing of data to facilitate fast and accurate information retrieval. Index design incorporates interdisciplinary concepts from linguistics, cognitive psychology, mathematics, informatics, and computer science. An alternate name for the process, in the context of search engines designed to find web pages on the Internet, is web indexing.

In the field of search engine optimization (SEO), link building describes actions aimed at increasing the number and quality of inbound links to a webpage with the goal of increasing the search engine rankings of that page or website. Briefly, link building is the process of establishing relevant hyperlinks to a website from external sites. Link building can increase the number of high-quality links pointing to a website, in turn increasing the likelihood of the website ranking highly in search engine results. Link building is also a proven marketing tactic for increasing brand awareness.

Duplicate content is a term used in the field of search engine optimization to describe content that appears on more than one web page. The duplicate content can be substantial parts of the content within or across domains and can be either exactly duplicate or closely similar. When multiple pages contain essentially the same content, search engines such as Google and Bing can penalize or cease displaying the copying site in any relevant search results.

A canonical link element is an HTML element that helps webmasters prevent duplicate content issues in search engine optimization by specifying the "canonical" or "preferred" version of a web page. It is described in RFC 6596, which went live in April 2012.

Trademark stuffing is a form of keyword stuffing, an unethical search engine optimization method used by webmasters and Internet marketers in order to manipulate search engine ranking results served by websites such as Google, Yahoo! and Microsoft Bing. A key characteristic of trademark stuffing is the intent of the infringer to confuse search engines and Internet users into thinking a website or web page is owned or otherwise authorized by the trademark owner. Trademark stuffing does not include using trademarks on third party website pages with the boundaries of Fair Use. When used effectively, trademark stuffing enables infringing websites to capture search engine traffic that may have otherwise been received by an authorized website or trademark owner.

Hummingbird is the codename given to a significant algorithm change in Google Search in 2013. Its name was derived from the speed and accuracy of the hummingbird. The change was announced on September 26, 2013, having already been in use for a month. "Hummingbird" places greater emphasis on natural language queries, considering context and meaning over individual keywords. It also looks deeper at content on individual pages of a website, with improved ability to lead users directly to the most appropriate page rather than just a website's homepage.
