Rather, download a screen reader (for Windows I like Windows Eyes), learn to use it, shut off your monitor and spend one hour trying to use the web. That will give you all the context that you need. Once you're armed with this experience, make navigating through your site with your screen reader part of your regular QA process.
If you follow these steps you will:
- craft sites that are significantly easier for people with visual impairments to use.
- build sites that are easier for search engines to crawl.
- gain an understanding of WCAG that you can apply to everything you develop.
This method will not prevent usability nightmares like horrible font/icons, but it will get you most of the way to WCAG.
