in this website all the links are just titles click here which could be problematic for someone using a screen reader to navigate through links separately which would just read click here and doesn't tell them where the links goes. therefore a better description of the link would be a better option such as "login" as a login link, etc.

this is an example of a good practice which immediately defines the word "RFQ as request for quote"

all the information is comprehensively divided into different headline with a corresponding picture

In this website most links are indicated with a red color contrasting from a white or a black color rest of the text. Even though this is good that the link is distinctive from the rest of the text, for people with color vision deficiency it might be hard to easily notice the link since there is no underline or visually different to the rest of the text other than the color

Example of bad practice: Insufficient color contrast the title saying "supplier opportunities" is placed over a picture of a Canadian tire store with various colors and a white color dominating the store sign which is very similar to the color used for the text over it. this makes it harder to recognize and read the text because of the insufficient color contrast
