(A) www.googlemerchandisestore.com/?utm campaign = fallsale
(D) www.googlemerchandisestore.com/?utm_campaign = fall sale
You should always use underscore(_) after utm and campaign parameter.
You cannot put spaces after the campaign parameter value like “fall sale” you need to use either “fallsale” or “fall_sale”.
You also shouldn’t use capital letters and you should make sure to use a question mark(?) separating the domain name and custom parameters.
