Web accessibility is the practice of making sure your website content can be accessed and understood by as many visitors as possible, regardless of their physical ability or technological barriers.
As a webmaster, you must ensure that your website can be viewed by both human visitors and Search Engine crawlers, and at times it can get a bit tricky to please both types of visitors.
It may not be always be possible to make all types of content accessible to all your visitors, but as far as possible, you should try to make the meaning of your content understood by everyone.
