Metadata
Metadata must be placed within the head of the document and should include information that's pertains to the page.
ARIA Landmarks
Rich Syntax
It is important that a developer does not code a webpage using only "divs" within landmarks.
HTML has a rich syntax that allow developers to inform the robots the purpose of the contents.
For example, developers should use
- Header tags (i.e. <h1/> - <h6/>) and paragraph tags (i.e. <p/>) for text to help robots understand how sections are broken down.
- Lists (i.e. <ul/> or <ol/>) with individual items (i.e. <li/>) when representation that is meant to be grouped together (i.e. navigation bar links).
- Tables (i.e. <table/>) with individual sections (i.e. <tr/> and <th/>) when arranging information into tables.
- Code (i.e. <code/>) when demonstrating code.
