Our Fresh Contextual Links service and other guest post services both involve placing links on external websites, but they differ in how they do it. A guest post involves contributing to a blog as a guest author, with the link typically being placed in an author bio. Our service, on the other hand, involves collaborating with relevant blogs to create a piece of content that includes editorial link mentions. This content is written in collaboration with the blog owner and published as their own piece, which can be seen as more natural by search engines like Google.
