HTTP Meta tags

HTTP Meta tags – examples and descriptions of their use – any my opionion on their importance.

I do not necessarily agree with or use all of these, but use this as a reference with some guidelines.
Don’t include them ‘just for the sake of it’, but if they are relevant – add them.


HIGHLY IMPORTANT ONES

Title

The Title Tag should contain no more than 70 characters (although 100 characters may be indexed depending on the engine).

TitleTitleTitle

Description

OK, its not exactly a META Tag, but the Description Tag can have up to 150 characters (although, 200 – 250 characters may be indexed and only a smaller portion of this amount be displayed). Also used in the browser top bar, tabs, and in the taskbar.

Keywords

In the Keyword tag use specific descriptive ‘words’ or ‘phrases’ to match the content on your site. You can use up to 200 characters with each word (or phrase) separated with a comma(,).


MEDIUM IMPORTANCE – USE IF REQUIRED

Robots

The values ALL and NONE set all directives on or off: [ALL=INDEX,FOLLOW] and [NONE=NOINDEX,NOFOLLOW].

MS Tags

Do you want Microsoft products to automatically generate smart tags on your web pages. No? Then add this!

IE6 Image Toolbar

I found this one to prevent the image options toolbar popping up in IE6 over the images.

Expires

Use “never” unless your site will expire. (Eg. Tue, 18 Apr 2006 14:57:09 GMT | Note: Requires RFC1123 date format.

Cache Control

Cache control level. None / Public / Private / no-Cache / no-Store

No Cache

This directive indicates cached information should not be used and instead requests should be forwarded to the origin server.

Copyright

Who is the Owner of the site? or the Company Name

Designer

The webmasters name

Revisit-After

Tell the search engines how often this page updates. (Eg. 21 days | Note: Most search engines do not support this Meta Tag)


LOW IMPORTANCE

Publisher

Owner, Webmaster, Company Name, etc..

Author

The Author Tag is for the person who wrote the material for the site. Usually the client.

Subject

The Subject Tag is for what your site is about. Business, music, hobby, cars. You can use up to 100 characters.

Classification

The Classification tag is similar to description but more in detail.

Geography

Where are you located? Insert your full address?

Language

Is your site in English, Spanish, French…..?

City

Your City

Country

Your Country

Distribution

Use [Global] unless it is a [Local] only site.


SPECIAL USE

Redirect / Refresh

Used to redirect browsers to another page, or refresh the current page.
‘0’ is the number of milliseconds, so use ‘3000’ for a 3 second redirect.
