Best Marketplace SEO Tools: 5 Powerful Tools to Improve Marketplace Visibility and Sales
Marketplace SEO runs on different rules than Google SEO. Here’s what actually moves the needle on Amazon and Etsy — and the tools worth paying for.
You can have a great product, competitive pricing, and strong reviews — but if shoppers can’t find your listing, none of that matters. Marketplace search doesn’t work like Google. There’s no backlink profile to build and no domain authority to grow. Instead, ranking comes down to keyword relevance in your listing, sales velocity, and how well your content matches what shoppers are actually typing into the search bar.
That’s why generic SEO tools built for websites often fall flat for marketplace sellers. What you need is software that pulls data directly from the marketplace itself — real search volume from Amazon or Etsy, not estimates borrowed from Google. Below are five tools built specifically for that job, along with an honest look at who each one fits and who might want to look elsewhere.
What Is Marketplace SEO?
Marketplace SEO is the practice of optimizing product listings so they rank higher in a marketplace’s internal search engine — think Amazon, Etsy, eBay, or Walmart Marketplace — rather than in Google. The goal is the same as traditional SEO (get found by the right buyer at the right moment), but the mechanics are different.
Marketplace SEO typically involves:
- Keyword research based on real, marketplace-specific search terms
- Product title and description optimization
- Backend or search-term field optimization (tags, hidden keywords)
- Competitor listing analysis
- Listing performance tracking and rank monitoring
- Reviews, ratings, and relevance signals
- Marketplace-specific ranking factors, like conversion rate and sales history
Marketplaces don’t publish their full ranking algorithms, so treat any claim about exactly how Amazon’s A10 or Etsy’s search algorithm weighs a given factor with some skepticism — including from the tools themselves. What the tools below are genuinely good at is surfacing the data you’d otherwise have no visibility into.
What to Look for in a Marketplace SEO Tool
Not every “SEO tool” that claims to work for marketplaces actually pulls marketplace-native data. Here’s what separates a genuinely useful one from a repackaged website SEO tool.
Marketplace keyword data
Search volume pulled from Amazon or Etsy directly, not Google Keyword Planner estimates that don’t reflect shopper intent.
Competitor research
The ability to reverse-engineer which keywords a competing listing ranks for, so you can find gaps in your own strategy.
Listing optimization
Guidance on where to place keywords in your title, bullets, description, and backend fields for maximum relevance.
Rank tracking
Ongoing visibility into where your listing sits for the keywords you’re targeting, so you know if changes are working.
Data accuracy
Estimates that are directionally reliable matter more than raw feature count. A tool with fewer features but tighter data beats a bloated one with guesswork.
Ease of use and pricing
A solo seller managing 20 listings needs something different from an agency managing dozens of client accounts. Match the tool to your workflow, not the other way around.

Helium 10 — Best for Advanced Amazon Sellers
Helium 10 is one of the most complete toolkits built for Amazon sellers, and its Cerebro and Magnet tools are the two most-used pieces for marketplace SEO specifically. Cerebro lets you reverse-search a competitor’s ASIN to see every keyword their listing ranks for — which is often the fastest way to find keyword gaps you’d never think to search for on your own.
Why it stands out: The reverse-ASIN research in Cerebro gives you a map of exactly which keywords are driving traffic to competing listings, including ones buried deep in backend search terms.
Key features:
- Cerebro: reverse-ASIN keyword research
- Magnet: forward keyword research and search volume data
- Listing Builder for optimizing titles, bullets, and backend terms
- Keyword rank tracking across Amazon marketplaces
Marketplace SEO strengths: Helium 10 can be useful when you want to understand not just which keywords exist, but which ones your specific competitors are already winning with — and where their listings appear to have an advantage over yours in search placement.
Pros
- Deep reverse-ASIN research
- Full suite beyond just SEO (PPC, inventory, listing audits)
- Strong for sellers managing several ASINs at once
Cons
- Steeper learning curve for new sellers
- Full feature set can feel like overkill for a single-listing shop
Best for: Amazon sellers managing multiple ASINs who want to systematically reverse-engineer what’s already working for competitors.
Who should skip it: If you’re just launching your first Etsy shop, this isn’t built for you — see eRank or Alura below instead.
Check Out Helium 10Jungle Scout — Best for Beginners and Product Research
Jungle Scout was one of the first dedicated Amazon research tools, and it’s kept its reputation for being approachable. Where Helium 10 leans toward power-user depth, Jungle Scout leans toward a cleaner workflow — useful if you’re still finding your footing with Amazon SEO and product research at the same time.
Why it stands out: Keyword Scout lets you reverse-search multiple ASINs at once to see which terms competing products rank for, then feeds directly into Listing Builder for on-page optimization — a smoother beginner-to-execution path than most competitors offer.
Key features:
- Keyword Scout for search volume and competitor keyword discovery
- Listing Builder with real-time optimization scoring
- Opportunity Finder for identifying underserved product niches
- Sales Analytics for tracking listing performance over time
Marketplace SEO strengths: Jungle Scout can be useful when you want to identify high-volume, relevant keywords and then immediately see how to actually work them into your title and bullets, rather than handing you a spreadsheet and leaving the rest to guesswork.
Pros
- Beginner-friendly interface
- Combines product research with listing optimization
- Strong educational content for new sellers
Cons
- Less granular than Helium 10 for advanced reverse-ASIN work
- Amazon-only — no Etsy or multi-marketplace support
Best for: New Amazon sellers who want product research and listing SEO in one place without a steep setup process.
Who should skip it: Established sellers who’ve outgrown the basics and need deeper reverse-engineering tools may find Helium 10 a better long-term fit.
Try Jungle ScouteRank — Best for Etsy Keyword Research
If you sell on Etsy, eRank is close to the default keyword research tool sellers reach for. It pulls search volume and trend data straight from Etsy rather than approximating it from Google, which matters a lot given how different Etsy shopper intent is from general web search.
Why it stands out: The Keyword Explorer shows Etsy-specific search volume, click data, and competition level side by side, and it also surfaces keyword trends across Amazon and eBay for sellers who list in more than one place.
Key features:
- Etsy-native Keyword Explorer with search volume and competition data
- Rank checker for tracking listing position over time
- Shop and competitor analysis
- Trend spotting for seasonal and rising keywords
Marketplace SEO strengths: eRank can be useful when you want to understand which keywords real Etsy shoppers are searching for, rather than relying on general SEO tools that estimate demand from Google data that doesn’t map cleanly onto Etsy’s shopper base.
Pros
- Etsy-native search data
- Free plan available for testing before you commit
- Simple, low learning curve
Cons
- Built for Etsy first — not a fit if you sell primarily on Amazon
- Advanced automation features are lighter than Alura’s
Best for: Etsy sellers who want reliable, Etsy-specific keyword and trend data without paying for a bloated all-in-one suite.
Who should skip it: Amazon-only sellers won’t get much use out of eRank’s core keyword tools.
Explore eRankAlura — Best for Etsy Listing Optimization
Alura covers similar ground to eRank on the research side, but it’s built around getting from research to an actually-optimized listing faster. Its Listing Helper scores your existing titles, tags, and descriptions and flags specific gaps, which makes it a good pick for sellers who find raw keyword data hard to translate into action.
Why it stands out: The Listing Helper gives you a live optimization score as you edit, so you can see the impact of a keyword change before you publish it — rather than guessing and checking your rank days later.
Key features:
- Listing Helper with real-time optimization scoring
- Keyword and product research tools
- Competitor shop analysis
- Review automation and shop management features
Marketplace SEO strengths: Alura can be useful when you want guidance on where to place keywords in your listing, not just a list of keywords to work with — narrowing the gap between research and the actual edits you make to a listing.
Pros
- Real-time listing optimization scoring
- Combines research with shop management tools
- Free plan with no credit card required to start
Cons
- Etsy-only, same as eRank
- Keyword database is smaller than some dedicated research-first tools
Best for: Etsy sellers who want a straightforward path from keyword research to an optimized, published listing.
Who should skip it: If deep keyword-database size matters more to you than optimization scoring, eRank may be the better starting point.
See What Alura Can DoSellerApp — Best for Agencies and Multi-Brand Accounts
SellerApp is built with a heavier emphasis on account-level analytics and reporting than a straight keyword tool, which makes it a natural fit for agencies or in-house teams managing SEO across several Amazon brands at once. It pairs keyword research with sales, inventory, and ad performance data in one dashboard.
Why it stands out: SellerApp’s Keyword Scout ties keyword-level insight directly to sales and ad performance data, which makes it easier to prioritize SEO work by which keywords are actually influencing revenue, not just search volume.
Key features:
- Keyword Scout for search volume, trends, and competitor data
- Listing quality and optimization scoring
- Sales, inventory, and ad performance analytics in one dashboard
- Agency Partner Network for multi-brand account management
Marketplace SEO strengths: SellerApp can be useful when you need to justify SEO priorities to a client or stakeholder with actual sales and ad performance data attached, rather than keyword metrics in isolation.
Pros
- Ties keyword data to sales and ad performance
- Built for managing multiple accounts or brands
- Dedicated agency partner program
Cons
- More setup involved than a single-purpose keyword tool
- Amazon-focused, with limited support for other marketplaces
Best for: Agencies, consultants, or in-house teams managing SEO across multiple Amazon brands or accounts.
Who should skip it: A solo seller with one shop and a tight budget will likely get more value from a lighter, cheaper tool like eRank or Jungle Scout.

Which Marketplace SEO Tool Is Best for You?
If you’re also running a Shopify storefront alongside a marketplace presence, it’s worth treating the two as separate SEO workflows rather than trying to force one tool to cover both — marketplace search and Google-facing ecommerce SEO reward different signals entirely, as covered in our guide to optimizing ecommerce product pages.
Frequently Asked Questions
What is marketplace SEO?
Marketplace SEO is the process of optimizing product listings — titles, descriptions, backend search terms, and images — so they rank higher in a marketplace’s own search engine, like Amazon or Etsy, rather than in Google. It relies on marketplace-specific keyword data and ranking signals, such as sales velocity and conversion rate, that don’t apply to traditional website SEO.
What is the best SEO tool for marketplace sellers?
There’s no single best tool for every seller — it depends on your marketplace and workflow. Helium 10 leads for advanced Amazon research, Jungle Scout is a strong starting point for beginners, and eRank or Alura are the go-to picks for Etsy sellers focused on keyword research and listing optimization.
Do marketplace SEO tools actually help improve rankings?
They can, but indirectly. No tool can guarantee a ranking boost, since marketplaces don’t publish their exact ranking logic. What these tools do reliably is surface keyword and competitor data you wouldn’t otherwise have, which helps you make more informed listing decisions instead of guessing.
What features should I look for in a marketplace SEO tool?
Prioritize marketplace-native keyword data, competitor research, listing optimization guidance, and rank tracking. Data accuracy matters more than raw feature count — a focused tool with reliable numbers beats a bloated suite full of estimates borrowed from Google search data.
Can I use regular SEO tools for marketplace SEO?
Not effectively on their own. General SEO tools pull keyword data from Google, which doesn’t reflect how shoppers search inside Amazon or Etsy. Marketplace-native tools pull data directly from the marketplace itself, which is a closer match to actual buyer intent.
Is marketplace SEO different from Google SEO?
Yes, significantly. Google SEO rewards backlinks, domain authority, and content depth. Marketplace SEO rewards keyword relevance in your listing combined with performance signals like conversion rate, sales history, and reviews — factors that barely register in traditional Google ranking.
Are marketplace SEO tools worth paying for?
For sellers with more than a handful of listings, usually yes. The time saved on manual keyword research alone often justifies the subscription, and several tools on this list — eRank and Alura in particular — offer free tiers so you can test the value before paying anything.
What is the best marketplace SEO tool for beginners?
Jungle Scout is generally the easiest entry point for new Amazon sellers, since it pairs product research with listing SEO in one guided workflow. New Etsy sellers tend to find eRank’s free tier the simplest way to start.
Final Verdict: Which Marketplace SEO Tool Should You Choose?
If you’re selling on Amazon and want the deepest competitor research available, Helium 10 is the strongest pick. If you’re newer to Amazon and want a gentler path from product research into SEO, Jungle Scout fits better. Etsy sellers have their own split: eRank for keyword-first research, Alura if you want optimization scoring built into the editing process itself. And if you’re managing SEO across several Amazon brands or client accounts, SellerApp’s account-level reporting is built for exactly that.
So, which one actually fits your workflow? Start with the marketplace you sell on, match it to the use case above, and try the free tier or trial before committing to a paid plan — your listings, and your data, are specific enough that no single tool is the right call for everyone reading this.
