What are links?
Links are the way you can direct visitors to a web page to other pages or sections of pages that may contain information relevant to them. They are made using the HTML <a> tag which means “anchor” to which is added the “href” attribute which contains the address to which the reference is made. Example link:
<a href="www.linkaddress.com"> keywords for link </a>
The types of links by their location
In their use, the links can be of two types: internal or external. Internal links contain links to other pages of the same site, while external links link to pages of other sites. These are important because they can give the user an easy experience in the navigation process, by highlighting important pages or sections. In other words, they are an important source for improving search engine rankings.
Types of links by content
Due to the fact that the links are “gates” that guide the user to certain pages that have relevant content, they can contain inside the anchor: images, text or video.
The types of relationships that the links with the cited locations may have
The “rel” attribute can be inserted inside the <a> tag, which can have the following values:
- Dofollow – This is the method by which it is suggested that the source to which the link is made is a reliable one (rel = “dofollow”, if the link lacks the attribute “rel”, “dofollow” can be interpreted as default) .
- Nofollow – unlike “dofollow”, this link does not guarantee the originality and trustworthiness of the referenced source, leaving this to Google crawlers (rel = “nofollow”).
- Canonical – provides information on the main source, respectively the basic address of a website (rel = “canonical”).
- Alternate – indicates language variants of the pages. They can be used with the “hreflang” attribute (rel = “alternate”).
- Sponsored – mentions that the quoted source paid for this link to appear alongside the content. It is often used for paid advertising (rel = “sponsored”).
- UGC – To avoid the possibility of placing “dofollow” links in the content of comments, they use the rel = “ugc” attribute by default. UGC stands for “User Generated Contend” and is designed to stop many people from trying to get backlinks quickly and for free by writing comments in which they insert a link (on blogs and forums). This relationship was implemented by Google with the idea that backlinks should not come from the cited source, but naturally from other people who appreciate the content and publish it on their pages.
