If you are looking for a PPC consultant, here are some tips to help you out and make sure you find a good one:
Does the consultant require a monthly fee to monitor and tweak the campaign? If they don’t or they have extremely expensive setup fees, I would run away fast! Daily management is needed for any good campaign!
Does the consultant have good references and testimonials? Be sure to CALL or EMAIL them before you pay anything for the service. This is critical and due diligence requires it!
Does the consultant mention tracking and analytics? If they don’t keep calling to find another firm. This is the most critical part. It does not matter how many people click on your Ad, remember, Google gets paid for EACH click (if you setup your campaign that way)… so the important thing is conversion.. you have to have tracking to see conversion…
Some some tips I thought I would share. Of course, we do all the above
