When I use dynamic keyword insertion how do I control capitalization? Does it take the capitalization of my uploaded keywords or can I control it by doing the following {Keyword} or {KeyWord}or {KEYWORD} etc.
No. You can't capitalize the keywords by following {Keyword} or {KeyWord}or {KEYWORD}. Instead you can use placeholders(param1,param2,param3) to capitalization of keywords. Eg. If a user search for a query "mountain bike" if you use {Keyword} in adtitle than the adtitle will be displayed as such as user enter in the browser. Instead if you use placeholder(param2) you can enter the value "Mountain Bike" in param2 of the keyword "mountain bike". In adtitle select Param2 instead of {Keyword}. Then if a user searches for "mountain bike" then your adtitle will be displayed as "Mountain Bike".
