Copyright aspects of hyperlinking and framing

While hyperlinking among webpages is an intrinsic feature of the web, some websites object to being linked to from other websites; some have claimed that linking to them is not allowed without permission.

Contentious in particular are deep links, which do not point to a site's home page or other entry point designated by the site owner, but to content elsewhere, allowing the user to bypass the site's own designated flow, and inline links, which incorporate the content in question into the pages of the linking site, making it seem part of the linking site's own content unless an explicit attribution is added.

Methods of website linking

This article pertains to methods of hyperlinking to/of different websites, often used in regard to search engine optimization (SEO). Many techniques and special terminology about linking are described below.

A reciprocal link is a mutual link between two objects, commonly between two websites to ensure mutual traffic.

For example, Trish and Roger have websites. If Roger's website links to Trish's website, and Trish's website links to Roger's website, the websites are reciprocally linked.

Website owners often submit their sites to reciprocal link exchange directories, in order to achieve higher rankings in the search engines. Reciprocal linking between websites is an important part of the search engine optimization process because Google uses link popularity algorithms (defined as the number of links that lead to a particular page and the anchor text of the link) to rank websites for relevancy.[citation needed]
Resource Linking

Resource Links are a category of links, which can be either one-way or two-way, usually referenced as "Resources" or "Information" in navbars, but sometimes, especially in the early, less compartmentalized years of the Web, simply called "links". Basically, they are hyperlinks to a website or a specific webpage containing content believed to be beneficial, useful and relevant to visitors of the site establishing the link.

In recent years, resource links have grown in importance because most major search engines have made it plain that—in Google's words-- "quantity, quality, and relevance of links count towards your rating."[1]

The engines' insistence on resource links being relevant and beneficial developed because many artificial link building methods were employed solely to "spam" search-engines, i.e. to "fool" the engines' algorithms into awarding the sites employing these unethical devices undeservedly high page ranks and/or return positions.

Despite cautioning site developers (again quoting from Google) to avoid "'free-for-all' links, link popularity schemes, or submitting your site to thousands of search engines (because) these are typically useless exercises that don't affect your ranking in the results of the major search engines[2] -- at least, not in a way you would likely consider to be positive,"[3] most major engines have deployed technology designed to "red flag" and potentially penalize sites employing such practices.

Forum signature linking

Forum signature linking is a technique used to build backlinks to a website. This is the process of using forum communities that allow outbound hyperlinks in a member's signature.

This can be a fast method to build up inbound links to a website; it can also produce some targeted traffic if the website is relevant to the forum topic. It should be stated that forums using the nofollow attribute will have no actual Search Engine Optimization value.
