tags don't count for a lot these days, except for the TITLE, so I'd tend to put
that first. It usually matches the page TITLE, though often adds the site title
(if different), and sometimes adds a sub title, especially if that includes key
The TITLE tag is absolutely vital. lack of title, misuse of title,
even duplicating one title on different pages, can contribute to a heavy dose
of Sick Site Syndrome.
For page TITLES, there's no absolute rule; I tend
to put "actual page title - category title - site title"; that makes
sense for readers, looks sane in search results, and, by its nature, includes
most keywords relevant to the page.
It's always useful to have the
<TITLE> tag feature the title of your site, as well as the page TITLE, rather
than hide that under the marketing blurb
"Page Title at Site Title,
the keywords pages"
To provide the best for SEs as well as visitors,
the TITLE should reflect the PAGE content. If it falls short, more general section
and / or site bits added on the end, would not hurt.
Failure to make full
use of the title tag means the site may look weak in the results listings - most
search engines use your title tag as the site title in listings.
this vital item - or using the same title across different pages - can contribute
to pages being diverted to 'supplementary listing', or, at worst, dropped completely.
