Accessibility And SEO
Are you aware that if your website is accessible it is also search engine friendly? By “accessible” I don’t mean that your website should be hosted on a server and it should be accessible to all your visitors, I mean that is assumed, right? Accessibility regarding websites means that your website is accessible to people of all abilities and this means that visually as well as physically challenged people should also be able to access your website and if they’re not able to access your website that means that your website is not accessible no matter if you get hundreds of thousands of visitors.
Aside from the government regulations, if you incorporate accessibility features into your website you make your website search engine friendly; this is because basically the search engine crawlers go through your website as if a browser for the visually challenged would access its contents.
But what constitutes an inaccessible website? An inaccessible website does not have a clearly defined navigation system. It is full of images and flash animations and other needless stuff. Now if you have a website that primarily deals with videos and images then you cannot help it but if you are having videos and images just as bells and whistles then you are needlessly making your website inaccessible to a big part of population who could have used your website to do business with you.
If you think that people who have visual or physical impairments anyway are not going to be your customers or clients then you are living away from reality because on the Internet you never know if 30% of your visitors have visual or physical limitations. Anyway this is not the main point of this post; the main point is that by making your website accessible you make it search engine friendly because the search engines like accessible websites and they don’t like inaccessible websites. Simple.
