Shopify SEO Keyword Research: The Exact Workflow for Finding Collection Page Keywords That Convert

Why Most Shopify Keyword Research Fails

Most keyword research for e-commerce starts and ends with head terms — "yoga pants," "leather handbags," "lifting belt." These are the highest-volume keywords in any product category and the ones that seem most valuable. They're also the most competitive, the slowest to rank for, and the lowest-converting because they attract the broadest intent. A brand targeting "yoga pants" is competing against every athletic apparel retailer in the country for visitors who may be doing price research, looking for inspiration, or comparing brands — not ready to buy.

The keyword research workflow that drives revenue works the other direction: start with the head term as a seed to generate a full universe of related keywords, then filter down to the keywords that have demonstrable purchase intent, achievable competition levels, and the right minimum volume to justify a collection page. The output is a prioritized collection page map — not a list of keywords, but a list of collection pages to build in order.

Step 1: Seed Keyword Research in Semrush

Open Semrush Keyword Magic Tool. Enter the broadest product category keyword as the seed — "yoga pants," "lifting belt," "leather handbag." This generates hundreds to thousands of related keywords across all intent types and competition levels. Apply three filters immediately: search volume minimum 100 per month (removes vanity keywords with no real demand), keyword difficulty maximum 40 (removes keywords that would require 12+ months of sustained link building to rank for), and intent set to commercial or transactional (removes informational queries that produce traffic but not purchases).

Export the full filtered list. This is the raw universe of potential collection page keywords for this product category — every option that meets the baseline thresholds for search demand, competition, and purchase intent. Most brands haven't targeted more than 10–20% of this list. The rest is uncontested collection page opportunity.

Step 2: Cluster Keywords and Map to Collection Pages

Group the exported keyword list into clusters — sets of related keywords that share the same searcher intent and could be served by the same collection page. "Women's yoga pants," "yoga pants for women," and "yoga leggings women" are one cluster — one collection page targets all three simultaneously, with the highest-volume keyword as the primary and the others as supporting keywords in the copy and H2s.

"High-waist yoga pants," "high-waisted yoga leggings," and "high-waist workout leggings" are a different cluster — a separate subcollection page. The distinction: the high-waist cluster has a different product attribute that differentiates it from the general women's cluster, and searchers for high-waist yoga pants have a more specific intent that a dedicated page can serve better than the general women's collection.

Each cluster that contains at least one keyword with 200+ monthly searches at KD under 30 warrants its own collection page. Clusters where the highest-volume keyword is below 100 searches per month can be combined into a single collection page covering a broader use-case, or deprioritized until higher-volume opportunities are built.

Step 3: Competitor Keyword Gap Analysis

Open the Semrush Keyword Gap tool. Enter the brand's domain and two to three direct competitors — brands of similar size selling similar products. Filter to keywords the competitors rank for in the top 10 that the brand's domain does not rank for at all. Sort by search volume descending.

These gap keywords are the collection pages the brand is missing that competitors have already built and ranked for. Competitors have done the proof of concept: these keywords can be ranked for at the brand's domain authority level, they have genuine search demand, and they produce traffic. Any gap keyword with 300+ monthly searches at KD under 40 is a priority collection page to build — it's a collection page a competitor owns that the brand doesn't, representing a direct revenue gap.

Step 4: Google Ads Conversion Validation

Pull the converting search terms from Google Ads search term reports over the last 90 days. Filter to search terms that produced at least one conversion. Cross-reference with the Semrush keyword list — any keyword that has produced a paid conversion and has organic search volume is the highest priority of all.

These keywords have already proven they produce sales. Not traffic. Not clicks. Actual purchases at the brand's conversion rate and price point. Building a collection page for a keyword that's converting in paid search and then ranking organically for that keyword produces two revenue streams from one keyword — the paid conversions continue while organic rankings grow, and eventually organic can carry a larger share of that keyword's revenue at near-zero incremental cost per click.

Building the Final Prioritized Map

Combine the research into a single prioritized collection page build order. Tier one: keywords with Google Ads conversion proof, sorted by search volume. These get built immediately regardless of KD. Tier two: competitor gap keywords with 300+ monthly searches at KD under 40, sorted by volume. These are the competitive catch-up pages. Tier three: Semrush clusters with 200+ monthly searches at KD under 30 not already covered by tiers one and two. These are the moat-building pages — the uncontested opportunities competitors haven't targeted.

Each collection page gets one primary keyword (in the meta title, H1, URL, and first sentence of the collection description) and two to four supporting keywords (used naturally throughout the copy and in internal link anchor text). Build in tier order, top to bottom by search volume within each tier. This sequence ensures that the highest-value, most-validated collection pages are live and indexed before moving to lower-priority opportunities.

Frequently Asked Questions

What keyword difficulty should Shopify collection page keywords target?

Under 40 as a starting filter, with the ideal range 15–35 for most brands. KD under 15 often catches untargeted opportunities — seasonal, occasion-specific, long-tail variants — that competitors have missed. KD 35–50 is achievable with 3–6 months of consistent link building. KD above 50 requires significant domain authority and sustained investment — worth targeting eventually, not first.

How many keywords should each Shopify collection page target?

One primary target keyword per collection page, with two to four supporting keywords used naturally in the copy. The primary keyword goes in the meta title, H1, URL, and first sentence. Supporting keywords appear throughout the description, in H2 subheadings, and as anchor text in internal links. Targeting more than one primary keyword dilutes focus and rarely produces top rankings for either.

Is search volume the most important factor in keyword selection?

No — purchase intent and conversion potential matter more. A keyword with 150 monthly searches and clear purchase intent will produce more revenue when ranked than a keyword with 2,000 monthly searches and ambiguous intent. The combination of search volume, keyword difficulty, and purchase intent determines priority — not volume alone. Google Ads conversion data is the strongest signal of which keywords actually produce revenue.

How do you identify purchase intent in a keyword?

Four signals: product type or name is explicitly mentioned; modifier words indicating buying behavior are present (buy, shop, best, for sale, or attribute words like leather, size, color); SERP inspection shows product and collection pages ranking (not blogs or Wikipedia); and the keyword logically ends in a product page, not an informational article.

Should a brand target keywords competitors are ranking for or keywords they're missing?

Both, in order. Competitor-ranked keywords validate that ranking is possible for a similar domain and are usually faster wins. Competitor-missing keywords are the moat-building opportunities — collection pages a brand can own before anyone targets them, building a lead that's hard to close once established. Replicate competitors' rankable keywords first, then expand into uncontested territory.
