When you give Google a keyword, you aren't just telling it what to target; you are telling it how strict to be.
Think of it like fishing:
Broad Match: A giant commercial trawler net. You catch everything—tuna, boots, sharks, and tin cans. Great for volume, bad for precision.
Phrase Match: A smaller, targeted net. You catch specific schools of fish, but might still get a few unexpected ones.
Exact Match: A speargun. You aim at one specific fish. You rarely miss, but you won't catch anything you didn't see coming.
Symbol: [brackets] (e.g., [red tennis shoes])
This tells Google: "Only show my ad if the user searches for exactly this meaning." It creates the highest relevance, which usually means a cheaper Cost Per Click (CPC) and higher conversion rate.
✅ Use this for:
Your highest value keywords: Terms you know lead to sales (e.g., "buy leather boots size 10").
Low Budget Campaigns: When you can't afford to waste a single penny on irrelevant clicks.
⚠️ The "Close Variant" Trap: Even Exact Match isn't 100% exact anymore. Google will still show your ad for misspellings or "same intent" variations (e.g., [lawn mowing] might match "cut grass").
Symbol: "quotes" (e.g., "red tennis shoes")
This tells Google: "The user's search must include the meaning of my phrase, but they can add words before or after."
Example: Keyword: "moving services"
Will Match: "Cheap moving services," "Moving services near me," "Best moving services for pianos."
Won't Match: "Moving house checklist" (doesn't include the core service).
✅ Use this for:
Core Keywords: When you want to capture long-tail variations without opening the floodgates to junk traffic.
Most Service Businesses: Great for catching "Plumber in [City]" or "[City] Plumber."
Symbol: None (just text, e.g., red tennis shoes)
This tells Google: "Show my ad for anything related to this topic." If you aren't careful, Google might show your "tennis shoes" ad to someone searching for "tennis racket" or "repair shoes."
✅ Use this ONLY if:
You use Smart Bidding: If you use "Maximize Conversions," Google's AI will filter out the bad clicks for you.
You have a large Negative Keyword list: You need to actively block bad terms.
You want to find NEW keywords: It's great for discovering search terms you never thought of.
💡 ClickSambo Critical Warning: Broad Match is the #1 source of invalid traffic. Because it casts such a wide net, it often picks up accidental clicks and bot traffic hiding in unrelated search terms. If you run Broad Match, you must have fraud protection active.
