Headings and Subheadings

Example H2

Headings and subheadings organize content for readers. Be descriptive but concise.
Make sure you do not have any empty headers
Headings and subheadings should always be nested and consecutive. An H2 will nestle under H1, an H3 under H2, and on down. Never skip a header level for styling reasons. Page titles will be H1s, top-level sections should be H2s, and subsequent inside those are H3 and beyond. Avoid excessive nesting.
H1s should clearly describe what users are about to read. A good example would be “Building Skills The 4 Keys to Bird Identification”. You may also want to use analytics to see what people are searching for to help craft your H1s. Pages should only have one H1, before the content.
Subheadings (H2, H3, etc.) break articles into smaller, more specific sections. They give readers avenues into your content and make it more scannable.
Include the most relevant keywords in your headings and subheadings, and make sure you cover the main point of the content.
Use title case, unless the heading is a punctuated sentence. If the heading is a punctuated sentence, use sentence case. Use sentence case for subheadings regardless of end punctuation.
Well written and semantic headings give screen reader users a way to quickly skim your site for the content they are looking for.
