All wrong depends on the Keyword. Broad is the roomlight. Phrase a Bulb and exact the laser. Maybe broad is cheaper because you match with a lot of sh*t nobody else would bid (but then your conversionrate will suck), Maybe exact you Ad matches better you have a higher CTR and CPC goes down (and CR up!? ). Brand has other fundamentals but also here can be both the case. Learn yourself more about account structure and matchtypes to evaluate the answer yourself. It’s no rocket sience but I already wrote to much Happy testing!
