Redundant links occur when multiple copies of the same link/link text appear on the same page of content.
Example of redundant link text:
The Texas State Bookstore has new t - shirts, and notebook materials for students! Visit the Texas State Bookstore today to find your spring textbooks. At the Texas State Bookstore, you can find all the supplies you need to succeed during your studies.
Example that avoids redundancy:
The Texas State Bookstore has everything you need to succeed during the Spring Semester including textbooks, study materials, and even Texas State t - shirts and accessories that help you show your Bobcat Pride!
Redundancy not only affects accessibility, but also makes your search engine optimization (SEO) worse when people search for web content related to your website.
