What is your experience with having all your keyword as well in Broad, Phrase and Exact. Is this a recommended strategy or might this hurt my in any way? Cheers!
No, won't hurt. Adwords selects the exact match if you have it first, then the phrase then the broad. Try to limit your broads however, especially short ones. I never use broad matches that have two words or less.
I agree with Lucid, but don't have them all in the same Adgroup and if possible split them into their own Campaign - you can get away with Broad & Phrase in the same Campaign however, if you don't have enough keywords to warrant them being split. Remember what Broad matches are for... you should use them to find out more exact (and in some cases Phrase) searches. As time goes by, your broad matched keywords should get less impressions, as you'll be adding negatives and exact/phrase matches (which will be triggered instead).
