An update from Google on link spam and qualifying links

July 26th, 2021

Many websites have begun monetizing via outbound links, which are present on many blogs on the internet today. Google has stated that webmasters need to be aware that if the links are overdone and not annotated correctly it could lead to a violation of their quality guidelines.

What are outbound links?

An outbound link, also known as an outgoing link or an external link, is a hyperlink on a web page that points to another web page or website outside of the current domain. These links direct users to external sources of information, resources, or related content on the internet. Outbound links are often used to provide references, citations, or additional information to readers and can contribute to a website’s credibility and authority by connecting it to reputable sources. They play a role in the broader context of search engine optimization (SEO) and can affect a website’s perceived quality and relevance to search engines.

In this context outbound links are often used as a way to monetize a users website encouraging their readers to purchase or click to an external site using sponsorship, affiliate, or otherwise commercial type links. If you do have relevant external links of a commercial nature you must follow Google’s best practices in order to avoid violating the quality guidelines.
