More than half of web users rely on search
engines to navigate pages.
When users link to a page from a search engine, they should know
immediately how the page relates to their query.
Highlight keywords, start the page with a summary, and follow the
guidelines listed under "Scannability".
Include in each page all possible query terms that can be
used to search for the topic of the page. List the most important terms
in a keywords meta-tag together with all common
synonyms (even ones not included in the body text). Include
generic terms used by customers or competing companies to describe
the topic of the page; do not include competitors' trademarks in
the meta-tag.
Syntax: <META name="keywords" content="Solaris
2.6, upgrade requirements, operating system versions">
Use a controlled vocabulary to add keywords to the meta-tags
for your pages: Create a list of common terms for your subject
area and make sure that each of these terms is added to the
keywords meta-tag for those related pages.
Do not add a keyword if the page is only peripherally related
to the term. Only use keywords that describe the main topic of a
page.
Each page must have a <TITLE> tag.
Create title text of a single line, typically
no more than 60 characters. Make sure that the first 40 characters
of the title describe the topic of the page: titles are often
truncated in navigation menus and by search engines.
Make the first word of the title the most
important descriptor of the page: Users often scan down long lists
of titles to choose pages.
Do not begin a title with a generic term ("Welcome to") or an article ("The").
The title should make sense when viewed completely
out of context, as part of a long list of other page titles.
Give different titles to different pages: Pages
about the same topic can start with the same words but should end
with words that explain the difference between them.
Titles can contain no markup or highlighting.
Titles must be written in mixed case.
In rare cases, a single keyword might be emphasized
by use of UPPERCASE (do not use for the first word in the title:
being first is sufficient emphasis).
Each page should have a short summary in a description
meta-tag. This summary is shown below the page title by some
search engines.
Descriptions must be 150 characters or less.
Descriptions must make sense when read completely
out of context of the site (though you can assume that they will
be seen together with the page title).
Descriptions should tell users what the page is
about and allow them to judge whether it is of relevance to their
current problem.
Do not fill descriptions with hyperbole or
promotional language; concentrate on the facts.
Syntax: <META name="description" content="How to
upgrade from Solaris 2.5 to Solaris 2.6: system requirements,
where to buy, link to online download.">
