There are lots of tools out there to expand your Google AdWords keywords by adding brackets (exact match) and quotes (phrase match) to your keyword list. Some of them are free, some are not, and even fewer options are available for Mac. But if you use TextMate a lot, like me, then you’ll enjoy this little keyword matching options command.
Open TextMate and show the bundle editor (⌃⌥⌘B). Create a new command by clicking the plus sign on the bottom left of the bundle editor. Name the command “Add Quotes” or something to your liking. In the right-hand pane, leave the ‘Save’ drop-down menu to ‘Nothing’, Copy sed 's/^/${1:"}/' | sed 's/$/${2:"}/' into the Command area, leave ‘Input’ to ‘Selected Text or Document’ and change the ‘Output’ to ‘Insert as Snippet.’ If you like, you can create a key command like ⌃⌥⌘”.
Next, create an “Add Brackets” command exactly the same way except copy this code into the Command area: sed 's/^/${1:[}/' | sed 's/$/${2:]}/'
Now, whenever you are want to add quotes or brackets to your keyword list, copy your keywords into a TextMate document and select them, activate your key command, and voilà, your keyword list has been transformed.
One more thing. If you have a list of keywords that you want to transform into a negative keyword list, do everything above except copy this code into the Command area: sed 's/^/${1:-}/'
