Pages must have Title Attributes and Title Headers
Page title attributes and headers help screen readers distinguish pages from each other. They are also important for Search Engines.
Title attributes appear in the tab or "chrome" of the browser window. When pages are created in Sharepoint, title attributes are automatically set to contain the name of the html file; but file names typically do not a make good page titles. Title fields, therefore, should be manually edited to clearly state the topic or purpose of the page in plain language.
Title headers are displayed in the content of the page. These must be manually added, and should almost always be formatted as <h2> html headers. Generally Title headers will be the same as the page's title attribute.

Link text must make sense when read out of context
Screen reader users have the option of having only the links on a page read aloud to them. In that context, a link that says "click here" is completely unintelligible.
The text for a link should make its target destination or function clear.
For example: instead of writing:
"For the registration form, click here."
"Please use our online Registration Form."
Avoid using color as the sole means of conveying information
Colorblindness affects almost 1 in 10 males, making it the most common visual impairment. Those with more severe visual impairments, of course, are unable to interpret color-coded meanings even with the help of a screen reader.
It is important, therefore, to avoid using color as the sole means of conveying information. If color-coding is used, be sure it is paired with another cue that conveys the same information.
