Title

Authors should use the TITLE element to identify the contents of a document. Since users often consult documents out of context, authors should provide context-rich titles. Thus, instead of a title such as "Introduction", which doesn't provide much contextual background, authors should supply a title such as "Introduction to Medieval Bee-Keeping" instead.

For reasons of accessibility, user agents must always make the content of the TITLE element available to users (including TITLE elements that occur in frames). The mechanism for doing so depends on the user agent (e.g., as a caption, spoken).

Titles may contain character entities (for accented characters, special characters, etc.), but may not contain other markup (including comments).

Keywords

The purpose of the keywords Metatag is to inform the spider or search engine of the main topics or points of a document. Due to extreme misuse of this Metatag it's relevance in many search engines has been downgraded. Keywords in the tag should also appear within your content, description, title, alt tags and elsewhere within your document to be considered by the search engines.

Here are some good rules of thumbs when using keywords.

• Limit keywords to under 1,000 characters.
• Do not repeat keywords more than 3 times.
• Use plural keywords.
• Don't repeat keywords hundreds of times in the Metatags, alt tags, description and text.
• Include misspellings and different cases.
• Use only the Metatags that make sense for your document.
