Accessibility
By using a tabindex greater than 0 you make an "anti-pattern" choice in that the element concerned is moved to the end of the tabulation order. For users of assistive technologies, this factor affects the user experience because it seems that some elements cannot be reached via the keyboard.
When an element has a tabindex value greater than 0, SeoChecker will notify it.
Remove the tabindex if you're using an element such as a form or a link with a parameter greater than 0.
Alternatively, when you use custom interactive components, set it to 0.
