Broad keywords
A keyword option that enables your ad to display changes and other relevant subjects when someone searches for that term. For example, you say Google Ads tries to show your ad for searches that contain the word or comparable if you add “hats” as the wide-patched keyword.
Example: If you search any product with just 1 Word, it is called Broad. e.g (Glass, Bag)
Short Tail Keywords
Short tail keywords are single-word search queries. They are less specific than more word searches by their length.
Example: If you search with 2 Words e.g (steel Glass, School Bag).
Long Tail Keywords
A long tail keyword is usually a three to five-word phrase. Since these keywords are unique to particular populations, they are more precise than general term. These keywords are less competitive than generic keywords as they are meant to represent more effectively how people inquire.
Example: If you Search it with 3 or 4 Words e.g (stainless steel glass, school bag for boy).
