As far as I know, the keywords and description meta tags are ignored by all search engines because spammers exploit the heck out of them. I suggest not bothering with them. However, if you still want to, read what the WordPress guys say.
As for Google Analytics and favicons, here are the plugins I recommend:
Don't forget to also add a favicon.ico to your site root (even an empty one will do) to stop browsers from repeatedly attempting to retrieve it. (Don't believe me? Install any WordPress favicon plugin and then check your server logs.)
The favicon.ico
in the site root will appear temporarily until the page has loaded enough for the <head>
to be parsed and the new icon loaded, so I suggest not leaving it empty. Some sites (eg. deviantART) even take advantage of that to display different icons for "loading" and "loaded".
