Link as a Service (LaaS) is a business model where advertisers (those who wish to purchase links) buy links on a monthly subscription basis, while link owners sell these links under the same subscription model. In this model, the service provider facilitates the connection between advertisers and link owners, managing the transactions, link placement, and maintenance. LaaS provides a scalable and efficient solution for advertisers looking to improve their online presence and SEO rankings through a continuous, subscription-based link acquisition system.
