Why Negative keywords for cost control in Digital Marketing? - Purpose & Use Cases

The Big Idea

What if you could stop wasting money on ads that never bring customers?

The Scenario

Imagine running an online ad campaign where you want to sell running shoes. Without filtering, your ads show up for searches like "free running shoes" or "cheap shoes giveaway." You pay for clicks from people who will never buy, wasting your budget.

The Solution

Using negative keywords lets you tell the ad system which words to avoid. This stops your ads from showing to uninterested people, saving money and focusing your budget on real buyers.
