Introduction
Are you running a Google Ads campaign but watching your budget vanish with little or no return? You’re not alone. One of the most common mistakes in PPC advertising is targeting the wrong keywords—high-volume terms that drive traffic but don’t convert. The result? Lots of impressions, few conversions.
That’s where PPC keyword research comes in.
In this guide, you’ll learn how to do keyword research for PPC campaigns that actually convert. We’ll cover everything from paid search keywords and intent to using the right PPC keyword research tools and analyzing your competition.
The goal? Helping you uncover the best Google Ads keywords that deliver high returns with minimal wasted spend.
What is PPC Keyword Research?
PPC keyword research is the process of identifying the most valuable terms to bid on—the ones most likely to drive qualified traffic and conversions.
Unlike SEO keyword research, where long-term rankings are the goal, keyword research for PPC is about immediate results. Every click costs money, so every keyword needs to earn its keep.
To put it simply: it’s not about what people search for. It’s about what buyers search for.
Example: A bakery bids on a broad keyword like “cake”. However, this also attracts searches like “cake decorations” or “cake delivery online”, which don’t match the bakery’s offerings or target audience.
Note: This doesn’t mean you should avoid broad terms altogether! Used carefully, these keywords are an important part of a balanced PPC strategy—more on that later.
What Makes a Keyword Profitable for PPC?
The best PPC keywords share a few traits, no matter your industry or product:
- High commercial intent: The searcher is ready to buy, not just browse.
- Low competition: This means lower CPCs and better ROI.
- Strong historical conversion rates: Use tools like Keyword Planner to estimate performance based on this data.
- Affordable Cost-Per-Click (CPC): So that your budget lasts longer.
Example:
❌ Bad PPC Keyword: “best cotton Tshirts for women” – too broad, vague intent, high competition.
✅ Good PPC Keyword: “cotton Tshirts for women under 500” – specific, high intent, buyer-ready.
But wait: what about keyword volume? Shouldn’t that also be considered?
Here’s Why High Keyword Volume Can Be Misleading in PPC
High search volume looks good, but don’t fall for it. Here’s why:
High Volume ≠ High Value
A keyword with 10,000+ searches sounds great, until you realize that many users are just browsing.
Example: “refurbished macbook” – High volume, but low intent. They might be comparing models or just curious about what “refurbished” involves.
Compare that to “deals for macbook air” – Lower volume, much stronger buying intent. The user knows the exact product and is searching for the best offer, which means they’re ready to purchase soon.
High Volume = High Competition
Popular keywords attract big advertisers with bigger budgets, which drives up:
- CPC
- Ad placement difficulty
- Overall campaign costs
High Volume ≠ High Intent
Search volume tells you how many people are searching, not why. And in PPC, transactional intent matters more than popularity.
✅ Look for terms that include: “Buy,” “get quote,” “order now”.
❌ Avoid research-stage phrases like: “What is,” “how does,” “top 10”.
The 4 Key Types of PPC Keywords
To build a rock-solid PPC strategy, use a mix of these keyword types:
1. Branded Keywords
These include your brand name. Great for defending your territory!
Example: “Puma running shoes”
2. Competitor Keywords
Bid on rival brands to grab attention.
Example: “Adidas running shoes” (when you’re selling Puma)
3. Generic Keywords
Broad terms with high traffic and cost.
Example: “running shoes”
4. Long-tail Keywords
More specific, less competition, higher conversions.
Example: “best running shoes for beginners”
Pro Tip: Long-tail and branded keywords have the highest intent and best ROI.
Search Intent: The Secret Sauce for PPC Success
All searches fall into one of four intent buckets:
- Navigational: Looking for a specific site – “Shiseido website”
- Informational: Seeking knowledge – “best wrinkle smoothing creams”
- Commercial: Researching purchases – “best Shiseido products for wrinkles”
- Transactional: Ready to buy – “buy Shiseido Benefiance wrinkle smoothing cream”
Out of these 4, commercial and transactional intent are your PPC goldmines. You can find these by analyzing Search Term Reports and using tools like Google Keyword Planner.
Keyword Length: Short-Tail vs. Long-Tail
Short-Tail Keywords
Example: “laptop”
Volume: 368,000, according to Backlinko.
CPC: 1.46 USD
Intent: Vague. Are they looking for reviews, brands, accessories, or just researching?
Conversion rate: Low, as the searcher is in the early awareness stage.
✅ Good for brand awareness
❌ Risky for limited budgets or high conversion goals.
Long-Tail Keywords
Example: “HP Pavilion 16 inch Laptop”
Volume: 140 according to SE Ranking.
CPC: 0.21 USD
Intent: High, they know the exact product they want.
Conversion rate: High, as they’re closer to a purchase decision.
✅ Good for eCommerce, B2B, or niche markets.
A study by WordStream found that the average conversion rate for long-tail keywords in Google Ads is higher than for short-tail keywords.
Keyword Match Types: How to Control Your Reach
Google Ads gives you three match types:
- Broad Match: Maximum reach. Expect some wasted clicks.
- Phrase Match: More targeted and greater control over search relevance.
- Exact Match: Precise targeting. Minimal waste. Low reach.
Pro Tip: Start with Phrase Match. Then refine once you see what works.
Why Does PPC Keyword Research Matter So Much?
Because the wrong keywords can be costly in more ways than one.
1. Wasted Budget
Imagine selling Adidas shoes but bidding on “Nike.” Ouch.
2. Low Ad Relevance = High CPC
Google rewards ads with high relevance. Great keyword targeting = better Quality Scores = cheaper clicks.
3. Poor Return on Ad Spend
If your keywords don’t convert, you’re not just losing money. You’re missing opportunities—like leads who could have signed up for a demo or trial, or customers who were ready to buy, just not through your ad.
4. Missed Seasonal Wins
Some keywords become profitable only during specific times—like “back to school laptop deals” or “Eid offers on smartphones.” Plan ahead and bid on them early for the best results. Miss the window, and you’ll pay more when the buyer searches (and the competition) peaks.
Mastering PPC Keyword Research: How to Drive High-Intent Traffic and ROI
Success in PPC comes down to PPC keyword analysis and refinement. Here’s a step-by-step breakdown of that process.
Step 1: Focus on buyer-ready terms
Look for intent signals like “buy,” “get quote,” or “order online.” These terms indicate that the user is ready to act.

Key Metrics to Keep in Mind

- Cost-per-click (CPC): Can you afford this keyword?
- Competition level: Are you fighting giants?
- Search volume: Don’t chase volume at the expense of relevance.
- Conversion probability: Would you buy after searching this?
