What the score measures
Five areas, weighted by how much they affect everything else. Tracking comes first because bidding, reporting and every decision depend on it. Reporting targets come second because without a break-even figure nobody can tell whether a campaign is working. Structure, creative and landing pages make up the rest.
What to do with a low score
Fix tracking before touching anything else. Then set targets, then structure. Creative and landing page work pays off fastest once the first three are solid, which is why our own engagements run in that order and why the first 30 days on every account start with an audit and a tracking rebuild.
