Example:
I have a phrase-match keyword "cheap office". But I want to restrict impressions to those searches who also include the keyword "London".
So for instance a search on: "London cheap office" would trigger my ad. As would "cheap office in London"; "a cheap office within London" etc.
How would I do this without have to enter all the variations as seperate keywords?
I could enter a broad match of London Cheap Office - but I'm trying to be more specific.
Find the most common phrases and bid them higher than the broad match (i.e. don't compete with yourself, make it so that the phrase has enough higher ad rank that it will trump the broad match).
If you find that the broad match keywords are receiving a lot of impressions, then you probably need more phrase match keywords.
