Adwords :what do you think about creating 2 different ad groups for each match type of the same kws into the same campagn?

[pupazzoinfame]

one modified broad and one exact.

ADGR1:
+red +cat +buy
+red +cat
+red +cat for +sale

ADGR2:
[red cat]
[buy red cat]
[red cat for sale]

Am i bidding agains myself without negative kws?

They are two very different groups and definitely worth using. Your exact will work well for users obviously typing in very specific keywords and could possibly be a bit more expensive to start with and your broad match keywords will help to find much more long tail requests.

I find +BMM is great for researching intent around the keyword and mopping up those not quite meeting exact rules. I would suggest then using the common longer string +BMM terms as exact to drive down the CPC in time.

After doing some serious digging and researching re: the classification of 'duplicate' keywords (there's a ton of information about how to remove them but the definition of what's a dupe and what's a 'variant' is really, really hard to find), there's a basic question about using redundant words within keywords that doesn't appear to be clearly addressed anywhere.

1. If you use the same root word _within a set of keywords, _are each of these keywords that use the same root word considered duplicates? To use the example above:

+red +cat
+red +cat +boots
+red +cat +bag

I would assume not— because each of these keywords that use the same word technically become a new keyword  variant with the addition of each new word. Is this accurate?

2. That said, Google offers a de-dupe setting to catch the re-use of words within _keywords,_and this seems to be used vaguely to define a keyword as a potential duplicate, but is this true in practice?

Thanks!
