I run alot of adwords campaigns and am spending about 1k a day and generally get a ctr of between 10% and 20%. A few weeks ago a competitor started using all caps of the keyword in the title for a few of their campaigns and my campaigns ctr took a nose dive. Now all their campaigns are using all caps and my campaigns are taking a beating and am spending about 1k a day on adwords. I'm assuming their using dki to do this as you can't directly post all caps. My question is knowing this against adwords tos should I start using all caps myself or just rat this guy out. What your take.
