You spent $200 on Google Ads last week. You got 150 clicks. Zero sales. Sound familiar? The problem isn’t your ad copy or your landing page. It’s your keywords. You’re bidding on terms people search for when they’re just curious, not when they’re ready to buy. This is the number one mistake beginners make with keyword research for Google Ads. Let’s fix it.
Why keyword research for Google Ads is different from SEO keyword research
In SEO, you want high-volume informational keywords. You write a blog post, get traffic, and hope some of it converts later. In Google Ads, you pay for every click. If someone clicks your ad and leaves, you lose money. That means you need keywords with commercial intent—people who are actively comparing products, looking for a deal, or ready to buy. Keyword research for Google Ads is about finding those buying signals, not traffic volume.
The 5-step beginner checklist for Google Ads keywords
Step 1: Start with a seed word that describes your product, not your brand
Don’t start with your company name. Start with what your customer calls your product. If you sell “organic dog food,” your seed word is “organic dog food.” If you run a “plumbing service,” your seed word is “fix leaky faucet.” Write down 3–5 seed words that describe the problem your product solves.
Step 2: Use Google’s Keyword Planner to find commercial intent keywords
Open Google Keyword Planner (free with a Google Ads account). Enter your seed words. Look at the suggestions. Ignore keywords with high search volume but low commercial intent. For example, “how to fix a leaky faucet” is informational. “emergency plumber near me” is commercial. Sort by competition and suggested bid to find keywords people are actually bidding on. This is a core step in keyword research.
Step 3: Filter for “buying” keywords, not “learning” keywords
This is where beginners fail. They see “DIY dog food recipes” with 10,000 monthly searches and bid on it. That’s a learning keyword. Someone searching that wants to cook dog food at home, not buy yours. Instead, look for keywords with:
– “buy,” “price,” “cost,” “near me,” “vs,” “review,” “discount,” “coupon”
– Service-based terms like “install,” “repair,” “rental,” “delivery”
– Product-specific terms like “organic dog food 30lb bag” or “Samsung fridge repair”
Build a separate list of these commercial keywords.
Step 4: Check the SERP for ad competitors before you bid
Before you add a keyword to your campaign, search for it on Google. Count how many ads show up. If there are zero ads, the keyword might not convert well (or it’s too low volume). If there are 3+ ads, you have competition. If the top 2 ads are big brands (Amazon, Home Depot, major chains), you might struggle unless your offer is unique. This quick check saves you from wasting money on high-competition terms you can’t win.
Step 5: Build a small, tight list of 10–20 keywords
Don’t start with 500 keywords. Start with 10–20 high-intent terms. This is called a “tight account” structure. It lets you:
– Write specific ad copy for each keyword
– Send traffic to a matching landing page
– Track performance without noise
You can expand later. A small, relevant list almost always outperforms a huge, broad list in the first month. Use SEO tools like keyword planners to verify volume and trends, but don’t let them dictate your list.
Common mistakes beginners make with Google Ads keyword research
- Broad match only: Broad match shows your ad for “dog food” even if you sell organic. Use phrase match or exact match to control who sees your ad.
- Ignoring negative keywords: Add negative keywords like “free,” “DIY,” “recipe,” “job,” “training” to exclude searchers who aren’t buyers.
- Mixing campaigns: Don’t put “buy organic dog food” and “best dog food for allergies” in the same ad group. Different intent needs different ads.
- Not using match types: Start with phrase match and exact match. Add broad match modified only after you have conversion data.
Mini scenario: how a local plumber cut wasted spend by 60%
A beginner plumber in Austin spent $300/month on Google Ads. He was bidding on “how to unclog a drain” and “plumbing tips.” He got clicks, no calls. He switched to commercial keywords: “emergency plumber Austin,” “clogged drain repair cost,” “water heater installation near me.” He also added negative keywords like “DIY,” “how to,” “tutorial.” In the first week, his cost per click dropped from $4.50 to $2.10, and he booked 3 jobs. The fix was simple: stop bidding on learners and start bidding on buyers. For a deeper performance check, pair your keyword research with a regular SEO audit to ensure your landing pages match what you’re promising in your ads.
