Marmalead and eRank are purpose-built for Etsy's internal search algorithm and give you data you can't get anywhere else—actual Etsy search volume, competition scores, and trending queries within the marketplace. Marmalead costs around $19–35 USD/month and shows engagement metrics like favorites and views per listing. eRank offers a free tier plus a $6–10/month pro plan with deeper analytics on tags, categories, and competitor tracking. Both tools scrape Etsy directly, so the keyword volumes reflect what buyers type into Etsy's search bar, not Google. If you're also driving external traffic from Google or Pinterest to your Etsy shop, layer in Ahrefs or SEMrush. These platforms don't understand Etsy's internal ranking factors, but they're excellent for finding what people Google before landing on Etsy product pages—phrases like "handmade leather wallet Canada" or "custom wedding invitations Ottawa." You can reverse-engineer competitor listings that rank on Google, then optimize your titles and descriptions to capture that search demand. Ahrefs starts around $130 CAD/month, SEMrush similar. Sale Samurai is another Etsy-focused option at roughly $10 USD/month. It's lighter than Marmalead but still pulls Etsy-specific data and offers tag suggestions. At Ottawa SEO, when we consult for e-commerce clients selling on marketplaces, we tell them to start with eRank's free plan to validate demand, then upgrade to Marmalead or add Ahrefs once they're doing $2,000+ monthly revenue. The mistake most Etsy sellers make is using only Google Keyword Planner—those volumes don't correlate with Etsy searches because the buyer intent and platform behavior differ completely. Etsy's algorithm weighs listing quality score, recency, and conversion rate heavily, so keyword research is just the entry point. You still need to test tags in live listings and track which ones drive actual sales, not just impressions.
