When to Let the Algorithm Work and When to Step In
One of the most common strategic decisions in paid advertising is choosing between broad targeting and interest targeting. At first glance, interest targeting feels safer. It looks more controlled and more intentional. Broad targeting, on the other hand, can feel risky — almost too open.
In reality, the choice is not about control versus chaos. It’s about timing, data, and learning speed.
Below is a clear breakdown of how to think about both approaches, with practical examples.

Broad targeting does not mean “no strategy.”
It means allowing the platform to decide who is most likely to respond, based on real behavior instead of assumptions.
When you choose broad targeting, you are saying:
Example:
A brand assumes its product is only interesting to people with specific interests. With broad targeting, the platform might discover that a completely different audience segment engages more, converts better, or costs less.
This kind of insight is often impossible to uncover with strict interest filters.
Interest targeting is built on what users say they like, follow, or interact with. While useful, it has limits.
Problems with interest targeting:
Example:
Someone may never follow pages related to a topic but still actively buy products in that category. Interest targeting would miss them. Broad targeting would not.
When an account has little or no performance data, the platform needs space to learn.
Broad targeting helps by:
Interest targeting at this stage often forces the system into a narrow box before it understands what actually works.
Example:
If you restrict targeting too early, the platform may struggle to find enough people to test creatives properly, leading to unstable or misleading results.
Interest targeting becomes more valuable after you see performance patterns.
This is the moment when:
Example:
If broad targeting brings traffic but quality is inconsistent, interest targeting can help refine delivery. At this stage, it’s not a guess — it’s an informed adjustment.
Targeting doesn’t work in isolation. Creative quality often matters more than audience selection.
Strong creatives:
Example:
A clear, well-written ad will attract the intended audience even with broad targeting, while a weak creative will fail regardless of how precise the interests are.
When budgets are limited, complexity becomes the enemy.
Instead of testing:
It’s often better to:
This approach produces clearer signals and faster learning.
Broad targeting is not a shortcut, and interest targeting is not a mistake. They are tools — and tools work best when used at the right time.
Broad targeting helps you discover.
Interest targeting helps you refine.
The biggest mistake is choosing one out of fear or habit instead of strategy. When targeting decisions are aligned with data, budget, and creative strength, performance becomes easier to scale and easier to understand.
