Dos

1. Make sure that the most difficult keywords (in terms of search volume and competitiveness) are on your homepage.
2. Use long tail versions or variations of the keywords you highlighted on the homepage for interior pages, which also means that each interior page title should be unique (meaning none are the same).
3. Place your most important keywords first in the title.

Don’ts

1. Don’t put “Home” on your homepage. Everyone knows it’s your homepage.
2. Don’t have a string of keywords in your page title. It just becomes redundant and spammy looking and more than likely you will be beyond the recommended 70 character limit. Remember only the first 70 characters are displayed in the search results. So get to the point.
3. Similarly, don’t have a sentence in your page title. Page titles commonly get confused with the “description” which unlike the title should be a
   declarative brief sentence summarizing the page.

For instance the Page Title for this article/page is – Meta Page Title Best Practices | Food For Thought. Doesn’t get any simpler than that.
