There are basically three ways you need to keep your website in check: W3C, Internet law, Device/browser compliant. These need to be checked and updated regularly.
W3C: If you don’t know, W3C is the group of folks who service the web and keep it running as smoothly as possible. They are the ones who set the standards and, from time to time, raise them. Their site offers an RSS feed of the latest news (this includes some, if not all, changes in Internet law) on keeping your site compliant in many different ways.
Device compliant: can your customers see you on their smartphone model #xxxxx? Do you need this compliancy if only 2 of your customers use this device? This is up to you, at least for now. But keeping abreast of the latest trends in mobile devices that connect to the Internet is also an ongoing compliancy practice you should have.
These are the top three.
Did you know that if you cater to folks with disabilities, the US government can shut down your site if it is not capable of being accessed by these folks.
I have a Site Compliancy Package that can research this all in one report.
