Keyword Research for Ecommerce: A Practical Guide

Keyword research is the foundation of any successful Shopify SEO strategy. Without it, you're optimising pages for terms that either don't convert, have no search volume, or are dominated by competitors with ten times your domain authority. Effective ecommerce keyword research is methodical, commercial, and rooted in understanding buyer intent.

Understanding Search Intent for Ecommerce

Every search query has an intent behind it. For ecommerce SEO, the four intents are: informational (researching a topic), navigational (looking for a specific brand or site), commercial investigation (comparing options before buying), and transactional (ready to purchase). Your product and collection pages should target commercial and transactional intent. Your blog should target informational and commercial investigation queries.

Building Your Initial Keyword List

1. 1Start with your product categories and subcategories as seed keywords
2. 2Enter seeds into Ahrefs Keywords Explorer or Semrush Keyword Magic Tool
3. 3Export the 'Matching terms' and 'Related terms' reports
4. 4Review competitor sites using Ahrefs' 'Competing domains' report to find keyword gaps
5. 5Mine your Google Search Console data for queries already triggering impressions
6. 6Explore Google's 'People also ask' and 'Related searches' for long-tail opportunities

Evaluating Keywords: Beyond Volume

Search volume is important but it's only one factor. For each candidate keyword, evaluate: keyword difficulty (KD), the commercial value (CPC is a proxy for advertiser value), search trend (rising or declining?), and the current search results page. If Google is serving content pages for your target keyword, that's informational intent and a collection page won't rank there.

Keyword Mapping: Assigning Keywords to Pages

Every page on your Shopify store should have a clearly defined primary keyword and a small set of secondary keywords. Maintain a keyword map — a spreadsheet linking each URL to its target keywords. This prevents keyword cannibalism (multiple pages targeting the same query) and ensures you have content planned for every keyword cluster you want to rank for.

Keyword Mapping by Page Type

• Homepage: brand name + primary category keyword (e.g., 'premium running shoes UK')
• Collection pages: category keywords (e.g., 'mens trail running shoes')
• Product pages: specific product queries (e.g., 'Nike Pegasus 41 mens size 10')
• Blog posts: informational and commercial investigation queries
• About/Contact pages: brand + location queries if relevant

Long-Tail Keywords for Ecommerce

Long-tail keywords — specific, lower-volume phrases — are the backbone of ecommerce SEO for stores without massive domain authority. A query like 'waterproof walking boots wide fit UK' has far less competition than 'walking boots' and is searched by someone with very specific, high-purchase-intent needs. Target long-tail keywords in product descriptions, variant pages, and blog content.

Seasonal Keyword Planning

Use Google Trends to understand the seasonal pattern of your keywords. Begin optimising and publishing content for seasonal keywords at least 2–3 months before peak season. Google needs time to crawl, index, and rank new or refreshed content. Creating Christmas gift guide content in November is too late — start in September.
