What it means in plain language
An advertising campaign is a planned set of promotional activities carried out within a specified time, budget and channels to achieve a specific goal.
Where it genuinely helps
An advertising campaign connects objective, audience, creative, media, landing experience and measurement; buying placement alone is not a campaign.
What to decide before acting
State the business decision the campaign should prompt and set brand, timing, cost and availability boundaries.
How to tell whether it works
Compare incremental effect, lead quality, frequency, cost and sales with a baseline rather than clicks alone.
