I've been using keywords separated by commas WITHOUT spaces.
What is the recommended method? WITH or WITHOUT spaces? Or there is no difference?

"Keywords are limited to 100 characters, so it’s important to be concise when describing your app. While spaces should not be used before or after the commas that separate keywords and keyword phrases, you can use spaces to separate words within keyword phrases. For example: Property,Real Estate,House."
