When formulating the title and description, make sure that your keyword appears at least in the title and is placed as far forward as possible.
Also, use other relevant search terms in the description. This usually comes naturally, since your page content is aligned with the keyword and search intent.

Short, crisp & mobile: Length of title and description

The title displays approximately 65 characters.
Desktop : The description allows approximately 165 characters.
Mobile : The description allows approximately 135 characters.
Present your arguments briefly and concisely so that they are easy for the user to understand.
