for example if the original term was
widgets in elbonia
and the clicks were lets say 10 a day, when i switch that to phrase match, the forecast clicks drop to under 1 a day
Would this be because previously the ad would be showing for just widgets and just elbonia, while now it would have to be widgets & elbonia?
I get pretty good clickthroughs on the seach network (ranging 2% to over 11%) but content is uniformally under 1% and often under 0.1%. To try and ratchet up the latter a bit I was plannign the above change across all words -- any suggestions advice much appreciated.
The most effective thing you can do is try on a small number of KW, see what happens, and eventually compare to the figures produced by the estimator.
Be sure to track even more closely the ROI, to see what influence would such a change bring.
