In the world of direct-to-consumer (DTC) e-commerce, success often comes down to one thing: how well you know your customers. While brands spend months optimizing their Shopify store, many ignore the goldmine of data tucked away in their marketplace channels — like Amazon and Walmart. That’s a missed opportunity.

In this post, we’ll explore how to connect your Amazon and Walmart data with Shopify in four concrete steps. By doing so, you can boost your SEO, replicate your winning offers, build stronger social proof, and run smarter retargeting campaigns. The result? Higher conversion rates, lower churn, and a more unified commerce strategy.

Data Silos Are Killing Growth

Most DTC brands operate in silos: marketplace data lives in Amazon or Walmart, and Shopify lives in its own bubble. But when your marketplace insights are disconnected from your Shopify storefront, growth dies in many subtle ways:

• You miss out on high-value search keywords that customers used on marketplaces.

• You don’t know which bundles or offers performed best, so you can’t replicate them on Shopify.

• You leave powerful social proof (reviews) behind.

• Your retargeting lacks the precision of marketplace-level SKU or buyer-level data.

To truly grow, you need to merge these data sources, and build a connected system where marketplace intelligence fuels Shopify conversions.

Use Marketplace Search Terms for Shopify SEO

One of the most underutilized assets in marketplace data is search terms — what people are actually typing on Amazon or Walmart to discover your products. These are pre-qualified, high-intent phrases.

How to leverage this:

1. Download search term reports: Use Amazon’s Search Term Report (for sellers) or Walmart’s equivalent to uncover top-performing keywords.

2. Analyze volume, relevancy, and conversions: Prioritize search terms that not only get impressions but also lead to orders.

3. Replicate on Shopify: Use these keywords in your Shopify product titles, meta descriptions, and collection pages. Because these are terms that already convert on marketplaces, they’re “ready-made traffic magnets” for your DTC store.

Why it works: Marketplace search behavior reflects real buyer intent. By using those phrases in your Shopify SEO, you’re aligning your store with what high-intent customers are already looking for.

Mirror Your Winning Offers

Next, identify which products, bundles, or offers are killing it on Amazon/Walmart, and bring them into Shopify — but with your own margin strategy.

How to do this:

• Analyze your best-performing SKUs or bundles on marketplaces.

• Recreate those product bundles on Shopify, but optimize pricing to maintain profitability (marketplace fees differ).

• Use Shopify’s flexible bundling or app solutions to make sure the same “winning combo” is available to your DTC customers.

Why it works: If something is already proven to sell well on Amazon/Walmart, there’s no reason not to replicate it in your Shopify store — especially when you can tweak pricing to improve margin and avoid marketplace fees.

Sync Reviews for Social Proof

Reviews are one of the strongest trust signals for buyers. If you’ve built up positive reviews on Amazon or Walmart, you should bring that social proof into your Shopify store.

How to import marketplace reviews:

• Use review apps like Judge.me to import Amazon reviews. Judge.me supports importing from Amazon via CSV or integrations. 

• After importing, you can display the reviews using intuitive widgets (star ratings, carousels, etc.). Judge.me’s Shopify app supports this. 

• If you also want to merge reviews across Shopify stores (e.g., different regional shops), you can syndicate reviews using SKUs. Judge.me uses SKU matching to sync reviews across stores. 

Important cautions:

• Make sure your import is compliant with Amazon’s Terms of Service and review policies. Some merchants have noted that mirroring reviews might risk policy violations. > “Amazon’s policies are very strict … using imported Amazon reviews … can be a violation.” 

• Use only authentic, verified reviews to maintain trust.

Optional: You can also use Loox, which allows importing reviews via CSV, including from Judge.me exports. 

Retarget Smarter with Marketplace IDs

Once you're leveraging marketplace data to feed Shopify, you can also get smarter with retargeting.

Strategy:

1. Map SKU-level data: Use the same SKU structure in Shopify that you had on Amazon/Walmart.

2. Retarget via Meta / Google Ads: Use SKU IDs from marketplace orders to build powerful remarketing audiences. For example, people who bought or browsed a particular SKU on Amazon can be retargeted on Facebook with a DTC offer on Shopify.

3. Personalize ads: Tailor your ads based on what buyers did on marketplaces — did they view a particular bundle? Did they buy one item but not a bundle? Use that data to personalize your retargeting flows.

Why it works: Marketplace behavior is extremely insightful. If someone bought from you on Amazon, chances are you can convert them to a higher-margin repeat purchase on your own Shopify store — if you retarget them with precisely the right SKU or bundle.

“Your customers move across platforms — your data should too.”

This is the heart of the strategy: don’t treat marketplaces and Shopify as separate silos. Your customers don’t shop in silos. Your strategy shouldn’t either.

Build a Connected Commerce Flywheel

By connecting marketplace data (search terms, offers, reviews, SKU-level behavior) with your Shopify store, you’re not just building a better site — you’re building a growth flywheel.

1. Use marketplace search insights → optimize Shopify SEO → attract high-intent traffic.

2. Mirror your best bundle offers → maintain profitability + appeal.

3. Import reviews → build credibility and trust.

4. Retarget using SKU-level data → drive repeat purchases and cross-platform conversions.

When executed well, this approach turns fragmented marketplace channels into a unified engine for growth — powering your Shopify store with proven data and converting more customers on your own terms.
