I recently had a client start bidding on their brand words only after they saw a competitor was bidding (poaching). Not only was someone bidding on the client’s brand, they were sending traffic directly to the client’s real website. There weren’t even diverting traffic to an outside site! By running ads on the client’s brand and sending traffic to the client’s domain, the official ads for the client are effectively blocked because the offending party was there first. Even though our client provided official and more accurate ads, they’d been blocked by a company that put up so-so advertising leading to the client’s website. This is a key reason you should be bidding on your own brand keywords for paid search.
