Negative keywords

In this lesson

  • What negative keywords are and why they save money
  • How negative match types differ from normal ones
  • How to build a starter negative keyword list

Short answer

Negative keywords are words you add so your ad does not show for certain searches. For example, adding “free” or “job” blocks people who will not buy. They cut wasted spend on irrelevant searches. Build a negative keyword list before launch, then add more weekly from your search terms report.

Why negatives matter

Say you sell aircon units in Davao. Without negatives, your ad may show for “aircon technician job hiring,” “how to fix aircon DIY,” or “aircon second hand free.”

Negative keywords filter out job, free, and DIY searches before they reach your adaircon price Davaoaircon technician jobinverter aircon near mefree aircon giveawayaircon DIY repairNegativekeywordsYour adshows only tobuyersblocks: job, free, DIY
Negatives stop clicks from people who will never buy.

None of these people will buy a new aircon. Each click still costs you. Negative keywords stop that.

How negative match types work

Negatives also have broad, phrase, and exact match. They work a bit differently:

Negative typeHow to type itBlocks searches that
Negative broadjobContain all the words, in any order
Negative phrase“second hand”Contain the exact phrase, in order
Negative exact[aircon]Are exactly that search, nothing more

One key difference: negatives do not cover close variants. If you block “job,” also add “jobs” and “hiring.”

Starter negative keyword list

Most small businesses can block these from day one, unless they apply to you:

  • Jobs: job, jobs, hiring, salary, vacancy, career
  • Free stuff: free, libre, download
  • DIY and learning: how to, tutorial, DIY, course
  • Second hand: used, second hand, surplus
  • Wrong places: cities or provinces you do not serve

You can save these as a negative keyword list in the Tools menu, then apply it to many campaigns at once.

Try it: block or keep

Searches for a Manila aircon shop that sells and installs new units:

Sort each item into the right group.

  • aircon installation Manila price

  • aircon technician job hiring

  • split type aircon for sale

  • how to clean aircon filter DIY

  • second hand aircon Tondo

  • inverter aircon near me

  • free aircon giveaway

Quick quiz

1. Which negative keyword stops job seekers?
2. Do negative keywords cover close variants?
3. Which negative would hurt a shop that wants buyers?

Common mistakes

  • Blocking words you actually need. A negative like “price” would block your best buyers.
  • Forgetting plurals and variants. Negatives do not catch close variants.
  • Adding negatives once and stopping. New irrelevant searches appear every week.
  • Blocking single words that matter. Be careful with words like “cheap” if you sell budget items.

Your action

Write 20 negative keywords for your business using the starter list. Save them in a note. You will add them when you build your campaign in Module 2.
