Hi
Can anyone help. Under Phrase or Exact Keyword options are variants of a words automatically included?
Do I need to use “swim hat” and “swimming hat” and “swimmers hat” OR if i just use “swim hat” will Amazon automatically include the other variants for the search?
Many thanks for any help

Amazon will not automatically include the other search terms, you will need to enter all the variations into your keywords.

Firstly I wouldn’t bother with Phase. Just stick with broad and exact.

For the example “Swim Hat”

Broad would include: “Swim Hats”, Swim Hats For Adults" " Beach Swim Hats" Etc

Exact would be just for the keyword “Swim Hat”
