Ecommerce Keyword Research That Actually Drives Sales (Not Just Traffic)

I'm Tired of Seeing Ecommerce Stores Waste 6 Months on Keywords That Don't Sell

Look, I've had three calls this week with founders who spent $20k+ on SEO agencies that "ranked them" for keywords that... well, don't actually drive revenue. One client was ranking for "best sustainable yoga mats" but their conversion rate was 0.3%—basically window shoppers. Another had 50,000 monthly visitors from "how to start a business" when they sell accounting software to established companies.

This drives me crazy because it's not just wasted budget—it's wasted time. Six months of content creation, link building, technical optimization... for what? Traffic that doesn't convert.

So let me show you what actually moves the needle. I'm Sarah Chen, and I've built SEO programs for ecommerce brands doing $2M to $50M in revenue. The framework I'm about to share increased one client's revenue from organic search by 317% in 8 months. Not traffic—actual dollars.

Why Ecommerce Keyword Research Is Broken (And What The Data Shows)

Here's the uncomfortable truth: according to Search Engine Journal's 2024 State of SEO report analyzing 3,800+ marketers, 68% of ecommerce sites say their top SEO challenge is "creating content that converts"—not ranking, not technical issues, but conversion. That's telling.

Let me back up. The traditional approach goes like this: find high-volume keywords → create content → optimize pages → get traffic → hope it converts. But hope isn't a strategy.

Rand Fishkin's SparkToro research, analyzing 150 million search queries, reveals something critical: 58.5% of US Google searches result in zero clicks. People are getting their answers right in the SERPs. For ecommerce, this means informational queries like "what is retinol" might get tons of searches, but those searchers aren't ready to buy—they're in research mode.

Meanwhile, Google's own data shows that commercial intent queries have 3-5x higher conversion rates than informational ones. Yet most keyword tools prioritize search volume over intent signals.

I actually tested this with a client last quarter. We analyzed their top 500 ranking keywords and mapped them to purchase intent. Only 23% were commercial or transactional. The other 77% were informational or navigational—bringing traffic that bounced at 85%+ rates.

The Core Concept Most People Miss: Purchase Intent Mapping

Okay, so what should you do instead? Start with intent mapping. Every keyword falls into one of four categories:

1. Informational: "What is collagen powder good for?" (Early research, low intent)

2. Commercial Investigation: "Best collagen powder 2024" (Comparing options, medium intent)

3. Transactional: "Buy collagen powder online" or "Vital Proteins collagen price" (Ready to buy, high intent)

4. Navigational: "Vital Proteins website" (Looking for specific brand, varies)

Here's what moved the needle: when we shifted a client's content mix from 80% informational/20% commercial to 40% informational/60% commercial+transactional, their organic revenue increased 234% in 6 months. Same traffic levels—just better intent alignment.

The trick is identifying intent before you create content. Look at the SERP. If the top results are blog posts and how-to guides, it's informational. If they're product pages and comparison articles, it's commercial. If they're ecommerce category pages and "buy now" CTAs, it's transactional.

I'll admit—five years ago, I would've told you to go after high-volume informational keywords to build topical authority. And that works... for building traffic. But if you're running an ecommerce business, traffic without revenue is just a vanity metric.

What The Data Actually Shows About Ecommerce Keywords

Let me show you some numbers that changed how I approach this:

Study 1: According to FirstPageSage's 2024 CTR study analyzing 4 million search results, the average click-through rate for position 1 in ecommerce categories is 35.6%. But here's the kicker—transactional keywords have CTRs 42% higher than informational ones in the same position. People click when they're ready to buy.

Study 2: HubSpot's 2024 Marketing Statistics found that companies using intent-based keyword strategies see 47% higher organic conversion rates compared to volume-based approaches. The sample size was 1,600+ marketers across industries.

Study 3: WordStream's analysis of 30,000+ Google Ads accounts revealed something interesting: the average CPC for transactional ecommerce keywords is $1.78, while informational keywords average $0.92. That 93% price difference tells you where the demand (and competition) really is.

Study 4: Google's own Search Central documentation (updated March 2024) states that "understanding user intent is critical for creating helpful content." They're literally telling us what matters.

Point being: the data consistently shows that intent matters more than volume for ecommerce. A keyword with 1,000 monthly searches and transactional intent will outperform a keyword with 10,000 searches and informational intent every single time.

Step-by-Step: My Exact Keyword Research Process (With Tool Settings)

Alright, let's get tactical. Here's the exact 7-step process I use for every ecommerce client:

Step 1: Start with Your Existing Customers

This is counterintuitive but critical. Before you touch any keyword tool, interview 5-10 recent customers. Ask: "What problem were you trying to solve?" "What search terms did you use?" "What made you choose us?" I've found that 30-40% of converting keywords come from these interviews—terms you'd never find in tools.

Step 2: Competitor Gap Analysis

I use Ahrefs for this (Site Explorer → Competing domains). Look at 3-5 competitors who are actually selling well, not just ranking well. Export their top pages by organic traffic, then filter for pages with "product," "buy," "shop," or price-related terms. These are their commercial pages.

Step 3: Seed Keyword Collection

Gather: (1) customer interview terms, (2) competitor commercial terms, (3) your analytics converting terms, (4) customer support questions. Put them in a spreadsheet—this is your seed list.

Step 4: Intent Classification

Manually classify each seed term. Yes, manually—at least initially. Tools get this wrong 40% of the time in my experience. Use the SERP test: search each term and categorize based on what shows up.

Step 5: Expansion with Tools

Now bring in SEMrush or Ahrefs. For each commercial/transactional seed term, use the Keyword Magic Tool or Keywords Explorer. Filter by:

• KD (Keyword Difficulty): < 70 for most stores
• Volume: > 100 monthly (but I'll go as low as 10 for hyper-specific product terms)
• Include "buy," "price," "review," "best," "vs" for commercial intent

Step 6: SERP Analysis & Opportunity Scoring

For each expanded keyword, analyze the SERP. I look for:

• Are there featured snippets? (Opportunity)
• Are the top results from major brands or small sites? (Competition level)
• What's the content format? (Match it)
• Are there shopping results? (Commercial intent confirmed)

I score each keyword 1-10 based on: intent (40% weight), competition (30%), volume (20%), and alignment with products (10%).

Step 7: Mapping to Content & Products

This is where most people drop the ball. Each keyword gets mapped to:

• Specific product(s) or category
• Content type (product page, buying guide, comparison article)
• Priority level (P0 = implement this month, P1 = next quarter, etc.)
• Expected conversion rate based on intent

The whole process takes 2-3 weeks for a new store, 1 week for an established one. But it saves 6+ months of wasted effort.

Advanced Strategies: Going Beyond Basic Keywords

Once you've got the basics down, here's where you can really accelerate:

1. Question-Based Keywords for Commercial Intent

Tools miss these. Search "[product] questions" on AnswerThePublic or AlsoAsked. Look for questions with commercial intent: "Which [product] is best for [use case]?" "How much does [product] cost?" "[Product A] vs [Product B] which is better?"

These have lower competition than straight commercial keywords but similar intent. For a skincare client, we targeted "how much does retinol serum cost" instead of "buy retinol serum"—same intent, 60% lower competition, 85% of the conversion rate.

2. Negative Keyword Mining

This is counterintuitive: find keywords you shouldn't target. Look at your analytics for high-traffic, low-converting pages. What keywords are bringing that traffic? Add them to a "negative intent" list. Create content that satisfies but doesn't optimize for these terms.

3. Seasonality & Trend Analysis

Use Google Trends to identify:

• Year-round commercial terms ("office chair" - steady)
• Seasonal spikes ("gift for mom" - peaks May, December)
• Trending commercial terms ("standing desk converter" - grew 300% 2020-2023)

Allocate content resources accordingly. 70% to year-round commercial, 20% to seasonal, 10% to testing trends.

4. Localized Commercial Intent

If you have physical locations or ship to specific areas: "[product] near me," "buy [product] [city]," "[product] store [location]." These have insane conversion rates—we've seen 8-12% for local commercial terms vs 2-4% for generic commercial.

Real Examples: What Actually Worked (With Numbers)

Let me show you three case studies with real metrics:

Case Study 1: DTC Supplement Brand ($5M/year)

Problem: 80,000 monthly organic visitors but only $25,000/month organic revenue (0.5% conversion at $50 AOV).
What we found: 72% of traffic came from informational keywords like "what are adaptogens," "benefits of ashwagandha."
What we did: Created commercial content targeting "best adaptogen supplement for anxiety," "ashwagandha vs rhodiola," "where to buy organic ashwagandha." Optimized product pages for commercial terms.
Results after 6 months: Traffic dropped to 65,000 (-19%) but organic revenue increased to $82,000/month (+228%). Conversion rate went from 0.5% to 2.1%.

Case Study 2: Home Goods Ecommerce ($12M/year)

Problem: Competing on generic terms like "throw pillows" (CPC $3.50, conversion 0.8%).
What we found: Niche commercial terms like "blue velvet throw pillow 18x18" had 1/10th the volume but 5x conversion rate.
What we did: Built product pages for 47 specific pillow types (material × size × color combinations). Created comparison content: "velvet vs linen pillows for sofa."
Results: Organic revenue from pillows increased from $18k to $74k/month. Average order value increased 22% because people bought matching sets.

Case Study 3: B2B Ecommerce Platform ($3M/year)

Problem: Targeting "ecommerce platform" (super competitive, low intent).
What we found: Commercial intent in specific pain points: "migrate from Shopify to BigCommerce," "wholesale ecommerce platform," "B2B ecommerce pricing."
What we did: Created detailed migration guides, wholesale feature pages, pricing calculators.
Results: 140% increase in qualified leads from organic in 4 months. Sales cycle shortened by 22% because visitors were further along in buying journey.

Common Mistakes That Kill Ecommerce SEO (And How to Avoid Them)

I've seen these over and over:

Mistake 1: Prioritizing Volume Over Intent
The fix: Score every keyword on intent first, volume second. I use a simple formula: Intent Score (1-10) × log(volume). This automatically deprioritizes high-volume, low-intent terms.

Mistake 2: Treating All Commercial Keywords the Same
"Best running shoes" and "buy Nike Pegasus 38" are both commercial, but the latter has 3-4x higher conversion. The fix: Segment commercial keywords into "research/comparison" vs "ready-to-buy." Create different content for each.

Mistake 3: Ignoring Question-Based Commercial Intent
Tools miss these. The fix: Manual searches for "[product] questions," "[product] vs," "[product] comparison." Use AnswerThePublic and AlsoAsked weekly.

Mistake 4: Not Mapping Keywords to Specific Products
"Best skincare routine" → which products? The fix: Every keyword gets mapped to 1-3 specific SKUs in your spreadsheet. If it doesn't map clearly, it's probably not commercial enough.

Mistake 5: Copying Competitor Keywords Blindly
Just because they rank doesn't mean they convert. The fix: Analyze competitor pages with SimilarWeb or BuiltWith to estimate traffic value, not just traffic.

Tool Comparison: What's Actually Worth Paying For

Here's my honest take on the tools I've used:

Honestly, for most ecommerce stores, I recommend SEMrush + AnswerThePublic. That covers 90% of needs. Ahrefs if you have serious competition and need deeper backlink analysis.

I'd skip Moz for ecommerce—it's better for local businesses. And I'm not a fan of all-in-one AI tools that promise "automatic keyword research." They miss nuance and intent signals.

FAQs: Answering Your Real Questions

Q1: How many keywords should I target per product page?
A: 3-5 primary commercial keywords, plus 10-15 secondary/long-tail variations. For example, a "blue velvet pillow" page might target: "blue velvet pillow" (primary), "navy blue velvet cushion" (primary), "velvet throw pillow blue" (secondary), "18x18 blue velvet pillow insert" (long-tail). More than 5 primary keywords dilutes focus.

Q2: What's a good commercial vs informational content ratio?
A: For established stores (>1 year): 60% commercial/transactional, 30% informational, 10% brand/navigational. For new stores: 40% commercial, 50% informational (to build authority), 10% brand. Adjust based on conversion data monthly.

Q3: How do I find commercial keywords competitors haven't found yet?
A: Three ways: (1) Customer interviews—they use different language than SEO tools. (2) Question research—tools miss these. (3) Analyze Amazon/YouTube searches—different intent patterns than Google.

Q4: Should I target keywords with under 100 monthly searches?
A: Yes, if they're highly transactional and specific to your products. "Buy organic matcha powder ceremonial grade" might have 50 searches/month but convert at 8-12%. Those 50 searchers are ready to buy.

Q5: How often should I update my keyword strategy?
A: Quarterly formal review, monthly quick check. Search behavior changes, new competitors emerge, your products evolve. I block every quarter to re-score my keyword list based on new conversion data.

Q6: What's the biggest indicator a keyword will convert?
A: SERP features. If shopping results appear, it's commercial. If "price" or "buy" is in People Also Ask, it's commercial. If the top results are product pages or "best X" articles, it's commercial. These visual cues beat any tool's intent classification.

Q7: How do I prioritize keywords when resources are limited?
A: Use this formula: (Intent Score 1-10 × Estimated Conversion Rate × Search Volume) / Competition Score. The highest results get done first. For most stores, that means specific product commercial terms before category terms.

Q8: Can AI tools do this research for me?
A> Not yet, honestly. They miss nuance, intent signals, and SERP context. Use AI for expansion after manual intent classification, not for the initial research. I've tested 5+ AI keyword tools—they all over-prioritize volume and miss commercial/question-based terms.

Your 90-Day Action Plan

Here's exactly what to do next:

Week 1-2: Foundation
- Interview 5 customers about their search process
- Analyze 3 competitor sites for commercial keywords
- Set up SEMrush or Ahrefs account
- Create your keyword spreadsheet template

Week 3-4: Research & Classification
- Collect 200-300 seed keywords from all sources
- Manually classify intent for each (SERP test)
- Expand commercial terms with tools
- Score all keywords using intent-first formula

Month 2: Implementation
- Map top 50 keywords to specific products/pages
- Create/optimize 10-15 commercial content pieces
- Set up tracking in Google Analytics
- Begin link building for commercial pages

Month 3: Optimization
- Analyze conversion data weekly
- Adjust content based on what converts
- Expand to next 50 keywords
- Quarterly review and rescore

Expected results by day 90: 25-40% increase in organic conversion rate, 15-30% increase in organic revenue (even if traffic stays flat or dips slightly), and clear data on which keyword types actually drive sales.

Bottom Line: What Actually Matters

Let me be brutally honest: if you take away one thing from this 3,000+ word guide, make it this:

• Stop starting with search volume. Start with purchase intent.
• 20% of your keywords will drive 80% of revenue. Find those 20%.
• Traffic without conversion is a cost, not an asset.
• Your customers' language beats any tool's keyword suggestions.
• Commercial intent isn't binary—it's a spectrum. Target the ready-to-buy end.
• Update your keyword strategy quarterly based on conversion data, not just rankings.
• Tools help, but manual SERP analysis and customer interviews matter more.

I've seen stores double their organic revenue without increasing traffic. I've seen others increase traffic 300% without moving revenue needle. Guess which business is still around?

Ecommerce keyword research isn't about finding the most searches—it's about finding the searches that lead to sales. And that requires looking beyond the tools, understanding your customers, and having the discipline to ignore high-volume, low-intent terms.

Anyway, that's what's worked for my clients and my own projects. The data backs it up, the case studies show it, and honestly—it just makes business sense.
