Ease of Use
Websites are the center of the classic Hub and Spoke marketing style. Whether your goal is to push conversions, page traffic, or site authority, the end goal is the same: get traffic to the site.
By using a link service, you are taking traffic that could’ve been going to your site. You are adding a barrier between your customers and where you want them to be doing.
Web Authority
Authority is the name of the game in many aspects of digital marketing. Ad placement, SERP scores, backlink value, ad revenue, and more are all affected by the authority search engines believe you have on the subject. While this subject is complex enough for many blogs, for this it’s simple enough to note:
Web authority can be built through links from other sites, customers valuing the site (visiting, spending time, and returning), and relevant content.
Using another companies link service, and adding that link to your media, can them additional authority while removing time customers spend on your site.
SEO
Search engines (SE’s) are companies; they have owners, shareholders, and are working to grow and profit. They do this by providing value to their users – Search engine ranking is the process of rating and listing content as the most to least relevant for their user, so they can provide the most value.
This value is found by many different factors (200+), but there are some with far more weight than others. The amount of time consumers spend on your site, the amount they engage with it, and the number of pages they view are HUGE indicators of value; using link trees takes away from these metrics.
