Understanding What Makes Keywords Expensive (or Cheap)
Before diving into tactics, it’s crucial to understand what drives keyword pricing in Google’s auction-based system. Keywords aren’t inherently expensive or cheap; their cost depends on several factors:
- Competition level: The more advertisers bidding on a keyword, the higher the cost
- Commercial intent: Keywords signaling immediate purchase intent typically cost more
- Industry: Some sectors (legal, insurance, finance) have naturally higher CPCs
- Quality Score: Google rewards relevant ads with lower costs
- Seasonality: Costs fluctuate based on seasonal demand
Understanding these variables helps identify opportunities for finding cost-effective keywords while maintaining conversion potential.
| Factor | Impact on Keyword Cost | Strategy to Leverage |
|---|---|---|
| Competition Level | Higher competition = Higher cost | Target niche-specific variations with lower competition |
| Commercial Intent | Stronger buying intent = Higher cost | Target earlier stages of the buying journey |
| Quality Score | Higher quality score = Lower cost | Improve ad relevance and landing page experience |
| Keyword Specificity | More specific = Generally lower cost | Use long-tail keywords and specific modifiers |
5 Research Strategies to Find Budget-Friendly Keywords
After managing hundreds of accounts, I’ve refined these five approaches that consistently yield affordable keywords without sacrificing quality:
1. Mining for Long-Tail Variations
Long-tail keywords typically contain 3+ words and are more specific than their shorter counterparts. They often have less competition and lower CPCs while attracting more qualified traffic.
For example, rather than bidding on “women’s shoes” (high competition, high CPC), target “comfortable women’s walking shoes for plantar fasciitis” (lower competition, more specific intent).
2. Leveraging the “Search Terms” Report
One of my favorite strategies is to analyze the Search Terms report in existing campaigns. This report shows exactly what users typed to trigger your ads, revealing often overlooked gems:
- Look for search terms with strong conversion rates but lower costs
- Identify patterns in converting queries (specific modifiers, question formats)
- Add these as exact match keywords in dedicated ad groups
3. Geographic Targeting Adjustments
Keyword costs vary significantly by location. By analyzing performance data across regions, you can:
- Identify locations with lower CPCs but solid conversion rates
- Increase bids in areas with better ROI
- Decrease or exclude areas with high costs and poor performance
4. Competitor Keyword Analysis
Tools like SEMrush and SpyFu let you see which keywords your competitors are targeting. Look for:
- Keywords they’re neglecting that fit your business
- Terms where they rank organically but don’t run ads
- Niche-specific terms they might have overlooked
5. Question-Based Keywords
Queries framed as questions often have lower competition while indicating strong intent. Use tools like Answer the Public to find question-based variations of your core terms:
- “How to” keywords show information-seeking intent
- “Which” and “best” questions indicate consideration stage
- “Where to buy” questions signal purchase readiness
| Research Strategy | Tools Needed | Expected CPC Impact | Best For |
|---|---|---|---|
| Long-Tail Mining | Keyword Planner, Ubersuggest | 20-50% lower CPCs | All industries |
| Search Terms Analysis | Google Ads interface | 15-30% lower CPCs | Accounts with existing data |
| Geographic Targeting | Google Ads location reports | 10-40% lower CPCs | Businesses that can serve multiple regions |
| Competitor Analysis | SEMrush, SpyFu | 20-35% lower CPCs | Competitive niches |
| Question-Based Keywords | Answer the Public, Google Search Console | 30-60% lower CPCs | Service businesses and information products |
Implementing Low-Cost Keywords in Your Campaigns
Finding affordable keywords is only half the battle; properly implementing them is equally crucial.
Campaign Structure for Cost-Effective Keywords
Structure your campaigns to maximize the impact of your budget-friendly keywords:
- Thematic ad groups: Group similar low-cost keywords together for relevance
- Separate campaigns by intent: Segregate informational, navigational, and transactional keywords
- Budget allocation: Direct more budget to campaigns with proven cost-effective keywords
Writing Ad Copy that Enhances Quality Score
To further reduce costs, craft ads that boost your Quality Score:
- Include the keyword in your headline and description
- Address the searcher’s intent directly
- Highlight unique selling propositions that competitors miss
- Use ad extensions to improve ad relevance without increasing costs
Landing Page Alignment
The often overlooked element of low-cost keyword campaigns is landing page relevance:
- Create dedicated landing pages for keyword groups when possible
- Echo the keyword terminology throughout the page content
- Ensure the landing page directly addresses the user’s search intent
- Optimize page load speed (which impacts Quality Score)
Optimizing Your Campaigns for Cost-Efficiency
Once your campaigns are running with inexpensive AdWords terms, continuous optimization is key to maintaining and improving performance.
Bid Adjustment Strategies
Smart bid adjustments can dramatically improve the efficiency of your affordable keyword campaigns:
- Device-based adjustments: Lower bids on devices with poor conversion rates
- Time-of-day scheduling: Identify when your cost-effective keywords perform best
- Audience layering: Increase bids for audiences that convert better
Negative Keyword Refinement
This strategy alone has saved my clients thousands in wasted ad spend:
- Regularly review search terms for irrelevant queries
- Create a tiered negative keyword structure (campaign vs. ad group level)
- Add close variants of your negative keywords
- Create a shared negative keyword list for enterprise accounts
A/B Testing for Lower CPCs
Testing isn’t just for conversion rate optimization; it can directly impact your keyword costs:
- Test different ad formats (responsive search ads vs. expanded text ads)
- Experiment with headline variations that include low-cost keywords
- Try different call-to-action phrases to see which improve Quality Score
| Optimization Tactic | Implementation Difficulty | Expected Cost Reduction | Timeframe for Results |
|---|---|---|---|
| Bid Adjustments | Medium | 10-25% | 1-2 weeks |
| Negative Keywords | Low | 15-30% | Immediate |
| Ad Copy A/B Testing | Medium | 5-20% | 2-4 weeks |
| Landing Page Optimization | High | 10-40% | 2-8 weeks |
The Power of Long-Tail Keywords for Affordable Campaigns
Long-tail keywords deserve special attention in any discussion about cost-effective AdWords strategies.
Why Long-Tail Keywords Are Often Budget-Friendly
These specific, multi-word phrases offer several advantages:
- Lower competition translates to lower CPCs
- Higher specificity means better qualified traffic
- Clearer search intent leads to more targeted ads
- Often convert better despite lower search volume
Finding Profitable Long-Tail Variations
To discover valuable long-tail keywords for your campaigns:
- Analyze autocomplete suggestions in Google Search
- Review “People also ask” sections for question variations
- Mine Google Search Console data for longer queries already bringing traffic
- Check online forums where your target audience discusses their needs
Implementing and Scaling Long-Tail Keyword Campaigns
While individual long-tail keywords have low volume, collectively they can drive significant traffic:
- Create themed ad groups around similar long-tail keywords
- Develop highly specific ads that directly address the long-tail query
- Use dynamic keyword insertion for ad relevance at scale
- Consider creating content-specific landing pages for major long-tail themes
Tracking ROI for Your Inexpensive Keywords
Finding cheap keywords is meaningless if they don’t generate returns. Implementing proper tracking is essential.
Setting Up Conversion Tracking
To accurately measure performance:
- Configure conversion tracking for all valuable actions (purchases, leads, etc.)
- Implement value-based tracking when possible
- Set up micro-conversions to track engagement
- Use Google Analytics to measure post-click behavior
Attribution Modeling for Low-Cost Keywords
Budget-friendly keywords often play important roles in the conversion path beyond last-click:
- Experiment with different attribution models (position-based, data-driven)
- Analyze assisted conversions for inexpensive keywords
- Track cross-device conversions for a complete picture
Customer Lifetime Value Considerations
Some low-cost keywords may attract customers with higher lifetime value:
- Segment conversion data by acquisition keyword
- Track repeat purchase rates by keyword group
- Adjust bidding strategies based on long-term customer value
| Tracking Element | Tools Required | Benefits for Keyword Strategy | Implementation Complexity |
|---|---|---|---|
| Basic Conversion Tracking | Google Ads Conversion Pixel | Identifies which keywords drive conversions | Low |
| Enhanced Ecommerce | Google Analytics + Google Ads Link | Tracks revenue and product performance by keyword | Medium |
| Attribution Modeling | Google Analytics, Google Ads | Values keywords throughout the customer journey | Medium |
| Lifetime Value Tracking | CRM + Google Analytics | Identifies keywords that bring valuable long-term customers | High |

Frequently Asked Questions About Cheap Keywords for AdWords
What’s considered a “cheap” keyword in AdWords?
This varies by industry, but generally, keywords that cost 50-75% less than the industry average CPC while still generating relevant traffic can be considered “cheap.” In some industries, this might mean $1-2 per click, while in others it could be $5-10.
Will cheap keywords convert as well as expensive ones?
Not all cheap keywords are created equal. Some low-cost keywords convert extremely well because they’re overlooked by competitors or highly specific to user intent. Others may be cheap because they don’t convert well. The key is testing and refinement.
How long does it take to find profitable low-cost keywords?
Initial research can yield candidates within a few days, but determining true profitability typically requires 2-4 weeks of campaign data. Continuous optimization over 2-3 months often reveals the most valuable opportunities.
Should I completely avoid expensive keywords?
Not necessarily. High-cost keywords with strong conversion rates and high customer value can still be profitable. The goal is to build a balanced portfolio of keywords across price points, with emphasis on the most efficient performers.
How often should I analyze my keyword costs?
Weekly monitoring is ideal, with deeper analysis monthly. Watch for cost trends, as formerly inexpensive keywords can become more costly as competition increases.
Can I use cheap keywords for branded queries?
Branded queries are typically inexpensive already since Google rewards relevance. However, competitors may bid on your brand terms, making it essential to protect your branded search presence.
Conclusion: Building Sustainable AdWords Campaigns with Cost-Effective Keywords
Finding and implementing cheap keywords for AdWords campaigns isn’t about cutting corners; it’s about maximizing efficiency. By focusing on relevant, intent-driven keywords that others overlook, you can build campaigns that deliver strong results without draining your budget.
