Indicate page titles by  using title tags : A title tag tells both users and search  engines what the topic of
a particular page is. The <title> tag should be placed  within the
<head> tag of the HTML document (1). Ideally, you  should create a
unique title for each page on your site.
Page title contents are  displayed in search
results : If  your document appears in a search results page, the contents of
the title tag will usually appear in the first line of the  results (if
you're unfamiliar with the different parts of a Google  search result,
you might want to check out the anatomy of a search result  video by
Google engineer Matt Cutts, and this helpful diagram of a  Google
search results page). Words in the title are bolded if they  appear in the
user's search query. This can help users recognize if the  page is
likely to be relevant to their search
The title for your homepage can list the name of your website/
business and could include other bits of important  information like
the physical location of the business or maybe a few of its  main
focuses or offerings
