I have always believed that TITLE tags should contain the important keywords and key phrases. This helps the web page to rank higher in search engines. I usually follow the keywords with the web site structure. I first put the the description of the present page (so that all keywords are contained in this description).
Be sure that all the keywords and key phrases are included in the <TITLE> tag.

You can use commas or hyphens to separate the key phrases in the <TITLE> tag.

You must remember not to use colons or the forward slash (/) in the <TITLE> tag. When you save a web page using the "Save As" option from the browsers "File" menu, the contents of the <TITLE> are used as the file name. Since colons are not allowed within filenames on a Macintosh system and slashes are used to represent directories, it's best to avoid them. Hyphens and commas, thus, seem as the best good choice.
