In this era of content, high-quality guest posts are an important part of a successful link-building campaign. A guest post is generally understood to be a blog post in your website niche linking back to your website. Here is a short example:
An online shop for kitchen cabinets wants to increase its visibility on the net through targeted link building. For this purpose, our link builder recommends your website as a quality source for buying kitchen cabinets to various bloggers and webmasters who write on the topics of kitchen remodeling, home improvement, living, etc, and publish regular content. Now a new blog post is written on the topic by one of the contributors to the blog on a relevant topic, for example, "What types of kitchen cabinets are there?" with a link to your website as a recommended source for kitchen cabinets. As a result, Google indexes the post and recognizes that your website is trustworthy, as it is recommended by other websites in the area.
