The "Shield" of Your Campaign

You pay for every click. Negative keywords keep you from paying for junk.

Most advertisers spend hours thinking about what they want to target. Smart advertisers spend just as much time thinking about what they don’t want.

A negative keyword is a flag that tells Google: "If a user searches with this word, do not show my ad."

If you sell "premium software" ($500/month) and you don’t add "free" as a negative keyword, your ad can show for "free software." You might pay $10 for a click from someone who has no intention of buying.

The "Universal Blocklist"

Words most businesses should consider blocking right away.

Before you launch, copy these lists into your negative keyword list. Unless you specifically offer these things, they only waste your budget.

Note: Before copying the list, make sure none of these words actually relates to your business.

How to Find Hidden Money-Wasters

Using the Search terms report.

You can’t guess every bad word. You have to look at the data.

1. Go to Campaigns > Insights and reports > Search terms. This report shows exactly what people typed into Google to trigger your ad, not just the keywords you bid on.

2. Sort the report by Cost.

3. Look for irrelevant terms. For example, you sell "office furniture," but you see you spent $50 on "office space for rent."

4. Check the box next to the term and click "Add as negative keyword." While adding it, edit the term down to just "rent" so you block every search that contains that word at once.

Pro Habit: Do this once a week. It is one of the fastest ways to lower your cost per acquisition (CPA).

Negative Keywords vs. Click Fraud Protection

Blocking the wrong intent vs. blocking bad actors.

It is important to understand the difference between negative keywords and ClickSambo.

• Negative keywords block the wrong intent. For example, a real person who wants something "free."

• ClickSambo blocks bad actors. For example, a bot or competitor who repeatedly clicks your high-intent keywords.

The Strategy: You need both. A good negative keyword list helps your ads show only to likely buyers. ClickSambo helps make sure those clicks come from real people, not bots draining your budget.
