How our title case works
The title case option capitalises the main words and keeps short words such as “and”, “of”, “in” and “the” in lower case, unless they start or end the title. This follows common style guides used for headlines. Short words in capitals, like SEO or GST, are kept as they are.
Avoid ALL CAPS in titles and ads
Writing a whole title or ad in capital letters can look like shouting, and Google Ads policies restrict excessive capitals. Use capitals for one or two short words at most. For page titles, use Title Case or Sentence case and check the result in our meta title generator.
