Link exchange is a method used predominantly in digital marketing[1], where two or more websites agree to display each other’s banners or links. This technique, which was popularized by the now Microsoft-owned LinkExchange, involves registering your sítio Web[3] with a central organization that generates HTML[5] code for your ads. These ads are then displayed on the websites of other members in the exchange, maintaining a ratio of two displays for every one of yours. While this can lead to a targeted readership and increased link popularity, it’s important to note that there can be disadvantages. Excessive link exchanges are often viewed as link schemes by Google[4], which may suppress your website in motor de busca[2] results. Google also discourages this activity as a means to gain an advantage in search engine rankings. Therefore, while link exchanges can be a stable method of hyperlinking, they should be used judiciously to avoid potential drawbacks.
A link exchange is a confederation of sítios Web that operates similarly to a web ring. Webmasters register their websites with a central organization, that runs the exchange, and in turn receive from the exchange HTML code which they insert into their web pages. In contrast to a web ring, where the HTML code simply comprises simple circular ring navigation hyperlinks, in a link exchange the HTML code causes the display of banner advertisements, for the sites of other members of the exchange, on the member web sites, and webmasters have to create such banner advertisements for their own web sites.
The banners are downloaded from the exchange. A monitor on the exchange determines, from referral information supplied by web browsers, how many times a member website has displayed the banner advertisements of other members and credits that member with a number of displays of its banner on some other member's web site. Link exchanges usually operate on a 2:1 ratio, such that for every two times a member shows a second member's banner advertisement, that second member displays the first member's banner advertisement. This page impressions:credits ratio is the exchange rate.
One of the earliest link exchanges was LinkExchange, a company that is now owned by Microsoft.
Link exchanges have advantages and disadvantages from the point of view of those using the World Wide Web for marketing. On the one hand, they have the advantages of bringing in a highly targeted readership (for link exchanges where all members of the exchange have similar websites), of increasing the "link popularity" of a site with Web search engines, and of being relatively stable methods of hyperlinking. On the other hand, they have the disadvantages of potentially distracting visitors away to other sites before they have fully explored the site that the original link was on.
Engaging in link exchanges or paid linking activity is highly discouraged by Google and not recommended for webmasters seeking an advantage in search engine rankings. Google considers excessive link exchanges and exchanging reciprocal links "Link Schemes" and can suppress the linked site in search engine results or block it altogether.
