Among the particular points of a Web page, if one had to optimize one of them, it would be without question its title. Standard HTML specified a special tag for the title of the page, and the search engines attached a great importance to it.
Your title must absolutely contain your most significant keywords. In general the title of the home page is the same as the name of the site, followed-up possibly of a small slogan. Preferably put the most significant words at the beginning.
It is also of primary importance not to repeat the same title on all your pages. On the one hand because you lose the possibility of varying the keywords, and on the other hand because if several pages of your site get listed in search engine results, the Net surfer is likely not to visit them all, thinking that it is about the same thing.
About the maximum (or optimal) length, one speaks on average about 60 characters, but this number is different according to the search engines.
