Title (Strongly Recommended)Your documents title will appear in user's hotlists, the banner of most browsers, and robot-generated lists. It should be a concise, one-line summary of what the page is about. Bear in mind that users may not reach your document through your homepage, but directly using a search engine or link at another site, so the title should ideally be self-sufficient. If this is a company website, try to include the name of your company here also. Instead of Tools and Supplies, make it Joes Hardware - Tools and Supplies.
Keywords (Strongly Recommended)Comma-separated list of key words for indexing your document.
Some robots look at keywords in context, so it is best to preserve word order and case, e.g. pizza, Vancouver, British Columbia rather than british vancouver columbia pizza. Try to use plurals for your keywords, search engines will process both singular and plural form. DO NOT REPEAT KEYWORDS!
Description (Strongly Recommended)The description is presented to the user along with the document's title as the result of a search.
Many robots use the first few lines of text as a description if the Description tag is not present. For documents using frames, it is possible that there is no such text present. Try to include your company name or website name here also. Use keywords in your description. Try to avoid superlatives (such as "best", "biggest", "coolest").
Author (Recommended)This tag names the author or creator of the page. This is useful if a searcher would like to find more pages created by you.
This tag will let you redirect your visitors to another URL after a specified amount of time. This is useful if your site changes URLs.
Robots (Recommended)See the workshop report at W3 for the full text.<META NAME="ROBOTS" CONTENT="ALL | NONE | NOINDEX | NOFOLLOW"> default = empty = "ALL" "NONE" = "NOINDEX, NOFOLLOW"The filler is a comma separated list of terms:
ALL, NONE, INDEX, NOINDEX, FOLLOW, NOFOLLOW.
Discussion: This tag is meant to provide users who cannot control the robots.txt file at their sites. It provides a last chance to keep their content out of search services. It was decided not to add syntax to allow robot specific permissions within the meta-tag.
INDEX means that robots are welcome to include this page in search services.
FOLLOW means that robots are welcome to follow links from this page to find other pages.
So a value of "NOINDEX" allows the subsidiary links to be explored, even though the page is not indexed. A value of "NOFOLLOW" allows the page to be indexed, but no links from the page are explored (this may be useful if the page is a free entry point into pay-per-view content, for example. A value of "NONE" tells the robot to ignore the page.
DHTML page transitions. These are the effects a user will see upon entering/exiting your site. These can annoy users. Use these sparingly!
