Shoppers do not search like readers. They qualify everything: size, material, recipient, occasion, price band, and they do it in the search bars of the stores themselves. E-commerce keyword generation means mining those bars, not just Google's.
Here is the marketplace workflow: Amazon's dialect, Etsy's dialect, the buyer modifier stack, and the page-type map that decides where each keyword lives.
Three search bars, three dialects
This is the commerce version of the dialect principle: generate where the intent lives, because the phrasing follows the platform.
Step 1: mine Amazon's autocomplete
Switch the generator on this site to the Amazon tab and run your product seeds. Amazon suggestions are pure shopper language: sizes, materials, compatibility, "for" phrases.
Watch for the qualifier patterns rather than individual phrases. If half the suggestions for your product append a size, size is a primary buying dimension, and your pages need it in titles, filters and copy.
Step 2: read the review vocabulary
Amazon reviews are the buyer's language after the purchase: use cases you never marketed, complaints that spawn "without X" searches, and comparisons to rivals by name.
Ten minutes in your category's top-product reviews yields seed gold like "doesn't overheat", "fits under the couch", "quieter than the [rival]". These phrases become both keywords and copy, and they came from the only focus group that paid to attend.
Step 3: stack the commerce modifiers
The standard modifier list covers buying words; commerce adds its own dimensions. Cross your seeds with these.
| Dimension | Modifiers |
|---|---|
| Spec | sizes, weights, counts, materials, colors |
| Compatibility | for [device], fits [model], replacement, refill |
| Recipient | for mom, for him, for couples, for teachers |
| Occasion | wedding, anniversary, housewarming, graduation |
| Values | organic, sustainable, handmade, hypoallergenic |
| Purchase shape | bulk, set, pack of, subscription, wholesale |
Recipient and occasion are the Etsy dialect specifically: on marketplaces where gifting dominates, "gift for new dad" outsells the product's own name.
Step 4: map every keyword to a page type
E-commerce keyword lists fail at the routing step: good phrases pointed at the wrong page types. The map is mechanical.
The test for any keyword: search it and look at what ranks. Google shows you which page type it considers correct, and your job is matching, not arguing.
Step 5: validate by CPC, not just volume
For commercial keywords, cost-per-click is the demand signal volume misses: advertisers only sustain bids on phrases that convert. A 50-search phrase with a $4 CPC is a better product-page target than a 5,000-search phrase at $0.10.
The volume tools attach CPC free. Sort your commerce list by it once and watch the priorities reorder themselves.
The one-line takeaway: mine the store bars, not just Google: Amazon for specs, Etsy for occasions, reviews for the real vocabulary. Then route by intent, product, category, guide or post, and let CPC pick the battles.
