Ecommerce SEO Lab is a US ecommerce SEO company that grows organic orders and revenue for Walmart Marketplace sellers. We work the four pillars of Walmart’s Polaris algorithm — Relevance, Performance, Offer, and Listing Quality Score — and measure every engagement in attributed Walmart GMV, not ranking screenshots.
You already know Walmart is too big to ignore. What brought you here is usually one of these.
The pattern behind almost all of these is the same: a provider running Amazon plays on Walmart. Walmart’s algorithm punishes that. The fields are different, the weighting is different, and the content rules are different — so the work has to be different.
Cross-listing Amazon copy to Walmart without rewriting for Polaris is the single most common reason a marketplace seller plateaus.
Solve Your Walmart Growth Blockers NowPolaris is Walmart’s customer-relevance engine — the system that decides which products appear, and in what order, on Walmart.com. It scores every listing on four pillars at once.
How well your listing matches the shopper’s query.
How your listing has performed in market.
How competitive your offer is right now.
Walmart’s internal 0–100 health score for your listing.
How well your listing matches the shopper’s query.
Item Spec 5.0 — Walmart’s structured-attribute framework rolled out in late 2025 — feeds Polaris the data it grounds on. Sparky, Walmart’s conversational AI shopping assistant, reads the same fields to answer shoppers in natural language. Listings that are attribute-complete and Sparky-readable get surfaced. Listings that aren’t, don’t. For the full primer, read our guide to what Walmart SEO is →
| Factor | Walmart SEO (Polaris) | Amazon SEO (A9 / Cosmos) |
|---|---|---|
| Algorithm | Polaris — customer relevance + offer competitiveness | A9 / Cosmos — sales velocity + keyword relevance |
| Highest-weighted ranking signals | Price competitiveness, fulfillment speed (WFS), Listing Quality Score | Sales velocity, conversion rate, keyword relevance |
| Backend search-term field | No dedicated backend field — Item Specs and attributes carry indexing | Yes — Search Terms field |
| Listing copy rules | Sentence case, no special characters, strict Style Guide | More flexible; bullets and capitalization tolerated |
| Structured attributes | Item Spec 5.0 — heavily weighted | Less structured; attributes secondary |
| Fulfillment lever | WFS + TwoDay tag boosts ranking | FBA + Prime badge boosts ranking |
| Cross-listing the same copy | Underperforms on Walmart; may violate Style Guide | Walmart copy on Amazon is similarly weak |

Every deliverable below is mapped to one of Polaris’s four pillars. We don’t sell “general optimization.”
We pull your LQS by SKU from Walmart Seller Center, build a remediation queue ranked by revenue impact, and re-score every 30 days. Most engagements lift average LQS from the 60s into the 85+ range within 90 days, which moves Polaris’s listing-quality input directly.
We source keywords from Walmart Search Insights inside Seller Center, Walmart’s autocomplete, Helium 10 Walmart, and DataSpark — not Google Keyword Planner. Titles are rewritten against Walmart’s 50–150 character range, sentence case, with the primary keyword in the first 30 characters and no prohibited terms.
We fill every attribute at the Product Type level, group variants (color, size, material) correctly, validate GTIN/UPC, and verify the Category → Product Type Group → Product Type chain against Walmart’s content standards. Most catalogs we inherit are 40–60% attribute-complete; we target 95%+.
Main images at 2000×2000 minimum on a pure white background. Secondary images for scale, lifestyle, and comparison. Product video where category data shows a CTR lift — Trellis has cited up to a 40% CTR lift on listings with video. Brand Shop layout and merchandising for approved brands.
We activate Walmart’s automated post-purchase review request, set a 48-hour response cadence on 1–3 star reviews, and syndicate reviews from your DTC site via Bazaarvoice where you already collect them. Review volume and average rating both feed LQS.
We monitor price competitiveness against the Buy Box winner SKU by SKU, analyze WFS eligibility and unit economics, track Pro Seller Badge criteria — 90+ days selling, 100+ orders in the last 90 days, ≥95% on-time shipment, ≤2% order defect rate — and flag in-stock-rate dips before they trigger ranking decay. Walmart Connect coordination (Sponsored Products, Sponsored Brands, Sponsored Videos) is included for scope alignment with the organic priority list. Full ad management is a separate service line — see our Walmart advertising services →
Three Walmart-specific engagements, with the situation, what we changed, and what it produced.
The brand launched on Walmart with Amazon copy and saw 90 days of launch-boost orders before traffic flatlined. We rewrote all 1,200 titles and descriptions against Walmart’s Style Guide, completed Item Spec 5.0 attributes across the catalog (43% complete at audit, 96% at month three), and built a Walmart Brand Shop.
The seller had 4,800 listings live but only 1,100 were attribute-complete enough for Polaris to surface on long-tail queries. We rebuilt the Product Type taxonomy across the catalog, completed technical attributes (material grades, dimensions, compliance tags), and tightened shipping SLAs to qualify for the Pro Seller Badge.
The brand was hitting a glass ceiling against two large Walmart-owned house brands. We rewrote every listing against Walmart’s Prohibited Content rules (supplements is a regulated category), enrolled the top 40 SKUs in WFS for the TwoDay tag, and syndicated 4,200 verified reviews from the DTC site via Bazaarvoice.
Walmart SEO with us starts at $2,500 per month, and price scales with catalog size, category competition, and whether you add marketplace + store coordination.
| Plan | Monthly | Best for | Core inclusions |
|---|---|---|---|
| Foundation | $2,500 | Walmart sellers doing $20K–$100K/mo on Walmart | LQS audit, listing optimization on top 100 SKUs, monthly reporting |
| Growth | $5,000 | Walmart sellers doing $100K–$1M/mo | Full catalog under management, Item Spec 5.0 rollout, reviews program, Brand Shop, Walmart Connect coordination |
| Scale | $9,000+ | $1M+/mo, or Walmart + store + Amazon coordination | Programmatic Item Spec build, multi-channel SEO, dedicated senior strategist, weekly cadence |
Honest answer: Walmart’s catalog refresh is faster than Google’s, so structural changes show in days — but compounding organic revenue takes six to twelve months.
— Listing changes pushed. Walmart’s catalog re-indexes within 24–72 hours.
— LQS scores lift on optimized SKUs (LQS recalculates within two to four weeks of content changes). No revenue lift yet.
— First non-branded keyword rank gains in moderately competitive categories. Highly competitive categories — supplements, electronics, beauty versus Walmart 1P — usually wait to month four or five.
— First measurable organic order lift. Pro Seller Badge eligibility window opens (90-day performance lookback).
— Organic Walmart becomes a meaningful channel. Buy Box win rate improves on optimized SKUs.
— Incrementality check. We run a holdout-style comparison against your prior trajectory, category trend, and Walmart Connect spend. If our work didn’t beat the counterfactual, we tell you.
— Walmart organic is a compounding revenue line.
Three things accelerate this curve: WFS enrollment, a healthy review base, and a clean catalog at audit. Three things slow it: an account under 90 days old, a single-SKU catalog, and prohibited-claim categories where every change needs compliance review.
Are an approved Walmart Marketplace seller doing roughly $20K+/month on Walmart, or have a credible path there. Want Walmart organic measured in orders and revenue, not rankings. Sell on Walmart alone, or on Walmart + a store (Shopify, Magento, BigCommerce, WooCommerce) + Amazon — we coordinate the channels. Have, or will give us, catalog ops support to push listing and attribute changes.
Aren’t yet approved on Walmart Marketplace — that’s a different service. Need Walmart revenue movement in under 60 days — use Walmart Connect, we’ll tell you that directly. Want guaranteed top-three rankings — no honest provider guarantees this, because Polaris weighs offer competitiveness and performance, which we can influence but not fully control. Have a Walmart budget under $1,000/month.
We’ve walked away from engagements where a brand new to Walmart expected SEO to replace ads in 60 days. That setup fails the seller, not us.

Walmart-native case studies with revenue numbers — not Amazon case studies with “Walmart compatible” added.
Can name and explain Polaris, Item Spec 5.0, and LQS — ask them to define each. If they hand-wave, walk away.
A defined methodology mapped to the four Polaris pillars — Relevance, Performance, Offer, LQS, each with named deliverables.
Revenue-tied reporting from Walmart Seller Center — not third-party tool estimates.
A first-90-day plan in writing — discovery, audit, priority fixes, first revenue report.
Walmart Connect coordination with scope clarity — they should align paid and organic without burying ad costs in the SEO retainer.
A senior Walmart strategist on your account, named — not an account-manager layer between you and the work.
Month-to-month terms after onboarding — confident agencies don’t need 12-month lock-ins.
AI shopping is now measurable. Walmart’s Sparky assistant answers shoppers conversationally on Walmart.com. ChatGPT, Gemini, and Perplexity cite brands and products for “best [product]” queries off-Walmart. Both source from your listing entities and your off-marketplace brand authority.
What we ship for AI visibility: Sparky-readable content — clear titles, complete attributes, FAQ-style description blocks answering common shopper questions in the language they use. Entity-rich Item Spec 5.0 attributes — the structured fields Sparky’s language model grounds on. Off-Walmart brand authority — verified reviews, editorial mentions, structured data on your DTC site that AI engines treat as ground truth when surfacing your brand. AI visibility tracking — monthly report of your brand-mention rate across ChatGPT, Gemini, Perplexity, and Google AI Overviews on your target product queries. Honest limit: AI visibility leans heavily on off-listing signals — reviews, mentions, structured DTC data — not on-listing work alone. We build both.
— Discovery call, Seller Center access, baseline pull: organic orders, organic GMV, LQS by SKU, ranking baseline, Walmart Connect spend split. Your senior Walmart strategist is named on call one.
— Full audit delivered. LQS by SKU, Item Spec 5.0 gap analysis, attribute completeness scoring, Buy Box loss diagnosis, category competitive benchmark, review-volume gap, fulfillment audit (WFS eligibility, Pro Seller Badge eligibility). Every finding ranked by revenue impact, with implementation instructions.
— Walmart keyword and category map across your top 50 SKUs. Rewrite priority queue. Content calendar for off-Walmart authority assets.
— Implementation sprint. Top-priority listings live. Item Spec 5.0 attributes pushed. Brand Shop updated if applicable. Reviews program activated. Walmart Connect alignment with organic-priority terms.
— First revenue report. Organic Walmart orders and GMV versus baseline, LQS movement, ranking movement on commercial terms, Buy Box win-rate change, AI visibility baseline.
After 90 days: a written plan every Monday, a report every Friday showing exactly what shipped with before/after metrics, and a quarterly business review that ties the work to revenue.
Walmart’s Polaris algorithm weighs price competitiveness, fulfillment speed via WFS, and Listing Quality Score more heavily than Amazon’s A9. Walmart has no backend search-term field. Listings copy-pasted from Amazon underperform on Walmart and may violate the Walmart Style Guide.
No, when the work follows Walmart’s Style Guide and Prohibited Content rules. We audit every change against current Walmart Marketplace standards before pushing, and we don’t make claims that trigger suppression in regulated categories like supplements, baby, or electronics.
Yes, in many categories. It requires strong LQS, competitive pricing, WFS or fast self-fulfillment, complete Item Spec 5.0 attributes, and a healthy review base. We’ve moved 3P listings to position one against Walmart-owned brands within six to nine months on prepared catalogs.
No, but ads accelerate sales velocity, which feeds the Performance pillar of Polaris. We coordinate organic and Walmart Connect so the channels compound. Full Walmart Connect campaign management is a separate service line.
No. Walmart and Amazon are independent ecosystems with no cross-platform duplicate-content penalty. Walmart listings should be Walmart-tailored against Polaris and the Style Guide; Amazon listings stay Amazon-tailored against A9 and the Search Terms field. We run both in coordination.
No. After a 90-day onboarding — long enough to deliver the audit, ship priority fixes, and produce a first revenue report — engagements run month-to-month with 30 days’ notice. All work transfers to you on exit, with no early-termination fees.
Walmart’s organic ranking algorithm requires custom catalog optimization. Learn how we capture multi-channel commerce in our Amazon SEO guide, and read our integrated results in our Supplements Brand Case Study.
We’ll audit your LQS by SKU, Item Spec 5.0 gaps, Buy Box loss patterns, keyword positioning, fulfillment eligibility, and AI visibility — then show you exactly where Walmart organic revenue is being left behind. No retainer until scope is agreed.
