How important is the page title?

[hadenpowell031]

There are a few clarifications that I require about the title of a web page. What is the relevance and significance of a page title and how much time does it take to become operative? Is there any kind of symbol or a specific word limit with which I should be familiar? If this is the case then what are the things that I should remember while creating a web page? Is it true that adding a keyword to the title helps to increase the competence and the productivity of the website? In fact, all that my client needs is to increase traffic. How can I change the length under such circumstances?
