By meeting WCAG Accessibility Standards (as per AODA legislation), and by writing quality web content, you will improve your search engine page rank. This is because search engines function in much the same way as a screen reader does: both are combing a webpage for information and depend on mark-up to interpret it.
Other great ways to achieve a good page rank include:
- considering what search terms a user would use in a search engine to find your content. Use those terms often (and properly) in the content you write;
- keeping your content succinct and relevant to the page topic; and
- removing outdated information and pages
