Keyword research is the foundation of every successful ecommerce SEO strategy. For online stores, the biggest traffic and revenue opportunities usually live on category pages — the pages that group related products together. This guide walks you through practical keyword research for ecommerce store categories, showing you how to find, evaluate, and prioritise both commercial and informational keywords that actually convert.
Why Category Pages Deserve Your Best Keywords
Many store owners obsess over product pages while neglecting categories. That's a mistake. Category pages target broader, higher-volume search terms like "running shoes for women" or "wireless noise-cancelling headphones." These queries capture shoppers who are still comparing options — a huge, high-intent audience.
Because category pages rank for competitive head terms, they typically drive far more organic traffic than individual product listings. Optimising them well means a single page can attract thousands of visitors instead of a handful. That's why smart keyword research for ecommerce store categories pays off faster than almost any other SEO task.
Understanding Search Intent for Ecommerce
Before you gather keywords, you need to understand what type of intent each query represents. In ecommerce, keywords generally fall into a few buckets:
- Commercial (transactional) intent: The user is ready or nearly ready to buy — e.g. "buy leather office chair," "cheap gaming laptops." These map directly to category and product pages.
- Investigational intent: The shopper is comparing — e.g. "best budget espresso machines," "top hiking backpacks 2024." These often become category pages with buying guides.
- Informational intent: The user wants to learn — e.g. "how to choose a mattress firmness." These belong in blog articles and guides, not category pages.
Matching each keyword to the right page type keeps your site relevant and prevents different pages from competing for the same term.
Step 1: Build a Seed Keyword List
Start with the words that describe your inventory. List your main product types, brands, materials, colours, sizes, and use cases. If you sell kitchenware, your seeds might include "cookware," "non-stick pans," "stainless steel pots," and "kitchen knives."
Don't overthink this stage. The goal is simply to capture the core vocabulary your customers use. You'll expand each seed into hundreds of long-tail variations in the next steps.
Step 2: Expand With Keyword Research Tools
Once you have seeds, use tools to discover the full universe of related searches. Recommended options include:
- Google Keyword Planner — free, great for volume ranges and discovering related terms.
- Ahrefs / Semrush — powerful for keyword difficulty, search volume, and competitor gap analysis.
- Google Search Console — shows queries your store already ranks for, revealing quick-win opportunities.
- Google autocomplete & "People Also Ask" — free sources of real-world phrasing and questions.
- AnswerThePublic — ideal for surfacing informational questions to fuel your content library.
Enter each seed keyword and export the suggestions. You'll quickly build a spreadsheet of hundreds of candidate terms.
Step 3: Mine Your Competitors
Your competitors have already done keyword research — so learn from them. Enter a leading competitor's domain into Ahrefs or Semrush and look at the pages driving their organic traffic. Pay special attention to their category URL structures and the terms those categories rank for.
A competitor gap analysis reveals valuable keywords you're missing entirely. It also helps you spot untapped niches where competition is low but demand is real.
Step 4: Group Keywords Into Category Clusters
Raw keyword lists are useless until they're organised. Cluster related terms that share the same intent into groups — each cluster becomes a candidate category or subcategory page. For example:
- Category: "office chairs"
- Subcategory: "ergonomic office chairs," "mesh office chairs," "leather executive chairs"
This clustering approach mirrors how shoppers actually browse and prevents keyword cannibalisation. It also creates a logical site architecture that search engines can crawl and understand easily.
Step 5: Prioritise by Volume, Difficulty, and Value
Not every keyword is worth pursuing immediately. Evaluate each cluster against three factors:
- Search volume: How many people search for it monthly?
- Keyword difficulty: How hard is it to rank against current top pages?
- Commercial value: How likely is the searcher to buy, and what's the margin on those products?
Prioritise clusters with strong commercial intent and manageable difficulty first. For newer stores, target lower-competition long-tail keywords to build momentum before chasing head terms.
Step 6: Balance Commercial and Informational Keywords
Category pages should focus on commercial and investigational terms, but don't ignore informational queries. Publish buying guides and how-to articles that target informational keywords, then link them internally to relevant category pages. This builds topical authority and captures shoppers earlier in their journey — funnelling them toward your revenue-generating categories.
Turning Research Into Optimised Pages
Once your keywords are grouped and prioritised, weave the primary term into the category page title, H1, meta description, and a short intro paragraph. Add supporting keywords naturally throughout descriptive category copy. Keep it readable — write for humans first, search engines second.
Effective keyword research for ecommerce store categories isn't a one-off task. Revisit your data quarterly, track ranking movements, and expand clusters as new products and trends emerge.
