Hey all,
I tried searching STM about this but I couldn't find any answers.
What exactly is the difference between a keyword filled with broad match modifiers and a phrase keyword?
In other words,
+workout +supplements = "workout supplements" ?
Aren't they the same? I know it wouldn't be the same if the modifier was applied to one of the words within the keyword. But if it's in all the words in the keyword, isn't it just like the phrase match version?
I heard that only using broad match modifiers in all the keywords is better than all the other match types. Is this true?
Looking forward to your response 
Modifier= Words that must be in the searched term however can be in any sequential order including additions at the front or end of the searched term
+workout +supplements
Example
big juicy supplements to workout at gym
workout supplements to get a boost
workout big ass antarctica supplements
Phrase= The searched term with only the words used in that particular sequential order including any additions added at the front or end of the searched term
"workout supplements"
Example
buy workout supplements
vegan workout supplements
workout supplements for the gym
workout supplements without peanut traces
workout supplements to spread over your woman
Hope that assists
P.S.
However I have come across accounts where the keywords have been activated by searched terms outside of that rule set.
The systems are not perfect but sometimes it's to help the ad platforms to make more money when the auctions are not so busy.
Take it with many pinches of cyanide, they are in the business of maximise profits so make sure you negative out unrelated keywords that are deeply unrelated so your investment sticks to the topics you want.
