For a limited time, search optimizing firm Engine Ready is releasing some of their tactics to the public.
The current release is Operation Camouflage and discusses ways to cloak your PPC campaigns so that the competition is not aware of your strategy and may very well underestimate your efforts. Essentially, the strategy involves adjusting your bids so that it appears to your competition that you have bowed out of a particular marketplace when, in fact you have simply adjusted the location of your prime bids.
The next release of a free online marketing strategy, "Ad Flint" is scheduled to be released at Search Engine Strategies in San Jose, CA, August 21-22. Look for Website Magazine at the show too!
