What is a subcategory in Shopify SEO keyword research?

A subcategory is a more specific version of a main category keyword implemented as a subcollection page. 'Running shoes' = main category. 'Trail running shoes for men' = subcategory. 'Trail running shoes for men under $150' = sub-subcategory. Each gets its own collection page and keyword, creating multiple SERP entry points.

Shopify SEO Keyword Research: The 11-Step Framework for Finding Winning Money Keywords

Why a Framework Beats a List

The typical keyword research process — export a list, sort by volume, pick the biggest numbers — fails for a consistent reason: no decision framework. Keywords end up on the wrong page type (blog content for transactional keywords, product pages for category keywords), the collection hierarchy is never properly structured, and ranking feasibility is never evaluated before content is created. The Show Me the Money framework runs every keyword through seven decision gates before anything gets assigned. The output isn't "here are keywords" — it's "here is the right page, in the right position, with a go/no-go on ranking right now."

Gate 1: Does the Keyword Have Transactional Intent?

Search the keyword in Google and read the top 10 results. If the top results are product pages and category pages from retailers, the keyword has transactional intent — it can be used on a money page. If the top results are blog posts, informational articles, or third-party review roundups, the keyword does not have transactional intent. Route it to the blog keyword workflow. A keyword without transactional intent will never rank a collection page or product page on page one regardless of optimization quality.

Gate 2: Collection Page or Product Page?

If the keyword passes the intent check: does it cover a range of products or one specific product? If multiple products in the catalog could satisfy the search, it belongs on a collection page. If it's specific to one SKU or model, it belongs on a product page. The practical test: would a user searching this keyword want to see multiple options side by side, or are they looking for one specific thing? Multiple options = collection page. One thing = product page.

Gates 3–5: Placing the Keyword in the Collection Hierarchy

The broadest level keyword for the product type — "running shoes," "yoga pants," "leather handbags" — goes on the main top-level collection page. Keywords with qualifiers — "trail running shoes for men," "high-waist yoga pants," "crossbody leather handbags" — go on subcollection pages nested under the main collection.

Subcategories can stack. "Trail running shoes for men" is a subcollection under "trail running shoes," which is itself a subcollection under "running shoes." Each level gets its own dedicated collection page with its own keyword. Every additional subcollection page is another point of entry for a buyer searching at that level of specificity — and another potential organic revenue source. Build subcollections as deep as the product catalog justifies.

Gates 6–7: Ranking Feasibility and the Alternative

Once the keyword is placed in the right position in the hierarchy, evaluate ranking feasibility. Check keyword difficulty against the site's current DR. Check the DR range of the current top 10 results — if the least authoritative result is DR 45 and the brand is DR 15, this keyword is not achievable yet. Assess topical authority: does the brand have enough supporting blog content in this category for Google to treat it as an authority? And evaluate search volume against the effort required to rank.

If the answer across all checks is yes — assign the keyword, optimize the page, move on. If no — find a close alternative. A keyword covering the same product category with meaningfully lower KD and a SERP populated by sites at a similar DR to the brand's current level. The alternative will have lower search volume, but it's achievable now rather than in 12 months. Assign it, rank for it, and build the domain authority that makes the original primary keyword achievable on the next review cycle.

Frequently Asked Questions

How do you know if a keyword belongs on a collection page or a product page?

If multiple products could satisfy the search, it belongs on a collection page. If it's specific to one SKU or model, it belongs on a product page. Would a user want to see multiple options or one specific product? Multiple options = collection page.

What is a subcategory in Shopify keyword research?

A more specific version of a main category keyword, implemented as a subcollection page. "Running shoes" is a main category. "Trail running shoes for men" is a subcategory. "Trail running shoes for men under $150" is a sub-subcategory. Each gets its own collection page and keyword — multiple SERP entry points for different buyer searches.

What should you do when a keyword is too competitive?

Find a close alternative — same product category, lower KD, SERP populated by sites with DR closer to the brand's current DR. Assign it now, rank for it, build authority, and revisit the original in 6–12 months as domain authority grows.

Should keyword research start at the category level or product level?

Always start at the category level and work down. Define main category keywords first, then subcategory keywords, then product-level keywords. Top-down approach ensures the collection hierarchy is correctly mapped before any product pages are optimized.

How do you evaluate whether a keyword has enough search volume?

Depends on AOV. Under 500/month often insufficient for low-AOV brands. 500–5,000/month strong ROI for most brands. Above 5,000/month typically too competitive for new brands but correct long-term targets as domain authority grows.
