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.

So how does your website become searching and friendly when you make it accessible?

  • With all the images you use the ALT text so that the browsers of the visually impaired surfers can make out what is there in the image.
  • You use the keywords in the hyperlinks. This tells people where the links are leading to.
  • Less use of JavaScript and flash animation. This way you remove from the website things that cannot be detected by the browsers for the visually impaired.
  • You have a sitemap at the top; this means all your links are immediately accessible with just a few clicks or tabs.
  • A meaningful page title means people with visual impairment can immediately make out what’s the page about because the title of your page is the first thing their browser reads.
  • Since the visually impaired can quickly scan through your web pages by tabbing to your headings and subheadings it makes perfect sense to clearly define them.
  • If you use CSS to create your layout it means that without the layout your text and the navigation bar appears in a linear fashion and this means it can be easily accessible to all browsers.

Hence you can easily make out that if you follow the accessibility guidelines you also end up making your website search engine friendly.
