Significance of page title

[jacksonsmith17]

I have some questions regarding the page title. Can anyone please tell me about the importance of page title? I want to know about the length of the page title. What is the maximum length of the page title? Does anyone know in detail about it? While selecting the page title, do I have to keep certain things in my mind? I recently got the advice that if I can add keyword phrases in my title, then I will be benefitted. Is this true? Is it possible for me to alter the chosen length of the page title? As per the needs of the visitors I want to increase the page title length of my article. Is it possible?

The maximum title length that Google will display and index in 66 characters including punctuation and spaces. If your page title length exceeds the maximum length, Google will cut off the title at the last full word.

From a search engine's point of view, page title is the first indication of the contents of the page. While many factors on and off the page affect how a search engine interprets the page, the page title is the leading indicator. Additionally, page title is the key information returned when search engines list results to a keyword search.
