Google dropped their December 2025 core update right before the holiday shopping hangover, and e-commerce sites are still picking up the pieces. Some gained 40% overnight. Others watched their traffic crater by half.
The pattern isn't random.
After analyzing movement across 200+ e-commerce sites (and talking to way too many panicked site owners), something became clear: Google fundamentally changed how it evaluates product pages. Not just tweaked. Changed.
Here's what actually happened and what you need to do about it.
The Product Content Depth Shift
Google's always said "quality content matters." Revolutionary advice, right up there with "drink water" and "get some sleep."
But this update made it concrete for e-commerce.
Sites with thin product descriptions got hammered. And I don't mean the obvious garbage—the dropshipping sites with three-sentence descriptions copied from AliExpress. Those were already struggling. I'm talking about legitimate retailers with 50-100 word descriptions that hit the basic specs.
Not enough anymore.
REI saw gains across their catalog. Backcountry held steady. Both have product pages that read like buying guides. They answer questions you didn't know you had. They compare similar products. They explain use cases.
Meanwhile, mid-tier retailers running on standard Shopify templates with manufacturer descriptions? Down 25-35% on average.
The threshold seems to be around 300-500 words of genuinely useful content per product page. Not keyword-stuffed nonsense. Actual information that helps someone decide if this specific product solves their specific problem.
One furniture retailer I spoke with added detailed room size recommendations, assembly difficulty ratings, and style compatibility notes to their top 200 products. Three weeks later, those pages recovered 80% of their lost traffic. The pages they didn't update? Still down.
User-Generated Content Became a Ranking Factor (For Real This Time)
Every few years Google "confirms" that reviews matter. Then nothing really changes.
This time something changed.
Sites with substantial review content—and I mean substantial, not five reviews with "Great product!"—maintained or grew rankings. Sites with sparse reviews or obvious fake reviews got crushed.
The signal seems tied to review depth and recency. Chewy consistently ranks well now, and their review sections are basically forums. People write paragraphs about their dog's reaction to a specific toy. Recent reviews matter more than old ones, even if the old ones have more volume.
Amazon's dominance in product searches actually decreased slightly for certain categories. Why? Because Amazon's review quality has degraded. Incentivized reviews, fake reviews, review bombing—it's a mess. Google seems to be deprioritizing pages where review authenticity is questionable.
Target and Walmart gained ground. Their verified purchase review systems apparently carry more weight now.
If you're running an e-commerce site without a robust review collection system, you're fighting uphill. And no, pulling in generic reviews from a third-party widget everyone else uses doesn't count. Google can tell.
Technical E-commerce SEO Got Stricter
Core Web Vitals have been "important" since 2021. But Google's been pretty forgiving about it for e-commerce sites because, let's be honest, product pages are heavy. High-res images, size selectors, color swatches, inventory checkers, recommendation engines—it adds up.
December changed the tolerance level.
Sites with Largest Contentful Paint over 3.5 seconds took hits. Cumulative Layout Shift above 0.15? Problem. This wasn't universal—some slow sites maintained rankings—but the correlation is strong enough to matter.
Wayfair apparently spent Q3 optimizing their mobile performance. Their product pages now load noticeably faster than competitors. They gained visibility across thousands of product terms post-update.
The tricky part? You can't just slap on a CDN and call it done anymore. Google's measuring the actual user experience, which means your third-party scripts matter. That customer service chat widget that loads 400kb of JavaScript? It's costing you rankings.
One mid-size apparel retailer removed their live chat feature (moving it to a button-triggered load instead of auto-load) and saw their CLS score drop by 60%. Rankings recovered within two weeks.
Speed isn't everything. But it's no longer nothing.
Structured Data Validation Became Non-Negotiable
Here's where it gets technical, but stay with me because this one's costing people money.
Google's been pushing structured data for years. Product schema, review schema, availability, pricing—all the markup that helps Google understand your page. Most e-commerce platforms add this automatically now.
Except they often do it wrong.
Post-update, sites with schema errors or inconsistencies got deprioritized. Not penalized exactly, but definitely not rewarded. Meanwhile, sites with clean, validated structured data saw improvements.
I'm talking about basic stuff:
- Price in schema doesn't match price on page
- Availability marked as "in stock" when product is actually backordered
- Review schema without actual reviews
- Multiple conflicting product schemas on the same page
BigCommerce and Shopify's default implementations are mostly fine, but custom builds? Check your Search Console. If you're seeing structured data errors, fix them. This isn't optional anymore.
One electronics retailer had a developer fix 2,000+ schema validation errors across their catalog. Tedious work. But three weeks later their product pages started ranking for more long-tail variations. Google apparently decided their data was trustworthy again.
The E-A-T Factor Extended to Commerce
Expertise, Authoritativeness, Trustworthiness—Google's been applying this to health and finance content forever. Now it's hitting e-commerce harder.
Sites that demonstrate actual product expertise rank better. This shows up in a few ways:
Buying guides that go deep. Not "10 Best Running Shoes" listicles. Actual guides that explain how to choose based on foot type, running style, terrain. The Wirecutter built their entire business on this. Post-update, their rankings strengthened.
Category expertise signals. Sites that clearly specialize in a category seem to rank better within that category than generalist marketplaces. A dedicated cycling retailer outranks Amazon for specific bike components now. That wasn't true six months ago.
Trust signals on product pages. Return policies, shipping details, warranty information—visible and clear. Sites that buried this stuff in footer links took hits. Sites that put it right on the product page maintained rankings.
Patagonia's product pages include repair guides and sustainability information. They're not just selling a jacket; they're demonstrating expertise about that specific jacket. Post-update? Their organic visibility increased.
The pattern is clear: Google wants to send people to sites that actually know what they're selling, not just sites that happen to have the product in stock.
Category and Collection Pages Matter More
Individual product pages got most of the attention, but collection pages saw significant movement too.
Generic category pages with just a grid of products and a one-sentence description? Down.
Category pages with introductory content, filtering guidance, comparison tools, and educational elements? Up.
Home Depot's category pages include project ideas, buying guides, and how-to content above the product grid. Their category rankings improved post-update. Lowe's, with thinner category pages, saw more volatility.
This connects to search intent evolution. When someone searches "running shoes," they're not always ready to pick a specific product. Sometimes they need help understanding options. Sites that help with that decision process—not just displaying products—are winning.
One sporting goods retailer added 200-300 words of genuinely helpful category content (not SEO filler) to their top 50 categories. Included comparison tables, use case explanations, and feature breakdowns. Those categories recovered faster than their unchanged categories.
The work matters. But it has to be actual work, not just hitting a word count.
Mobile Experience Became the Primary Signal
Google's been "mobile-first" for years. But this update made it obvious they're not kidding anymore.
Sites with poor mobile product experiences got hit hardest. And "poor" isn't just about responsive design. It's about the actual shopping experience:
- Can you easily see product images on mobile?
- Are size/color selectors usable with a thumb?
- Is the add-to-cart button visible without scrolling?
- Does the mobile page load without horizontal scrolling or zoom requirements?
Zappos maintained strong rankings. Their mobile product pages are genuinely usable. You can see shoes from multiple angles, check sizing, read reviews, and buy—all without frustration.
Compare that to sites where you have to pinch-zoom to see the size chart, or where the product description is buried below three screens of images. Those sites struggled post-update.
One fashion retailer did mobile usability testing and discovered their size selector was nearly impossible to use on iPhone. They redesigned it, made it thumb-friendly, and saw mobile rankings improve within a month.
Test your product pages on an actual phone. Not in Chrome's device simulator. An actual phone. If it's annoying to use, Google knows.
What to Do Right Now
Look, if you're running an e-commerce site and you got hit, you've got work ahead. But it's not mysterious work.
Audit your top 100 product pages. Check word count, review volume, schema validation, and mobile usability. Find the patterns in what's down versus what's holding steady.
Prioritize products by revenue impact. You probably can't fix everything at once. Start with products that actually drive sales.
Add genuinely useful content. Not SEO content. Useful content. Answer the questions people ask before buying. Compare to similar products. Explain use cases. Make the page helpful.
Fix technical issues systematically. Schema errors, Core Web Vitals problems, mobile usability issues—these are measurable and fixable. Start with Search Console data.
Build a review collection system that works. Post-purchase emails, incentives for detailed reviews, moderation to maintain quality. This is long-term work but it matters now.
Test everything on mobile. Not once. Regularly. Your mobile experience is your primary experience in Google's eyes.
The December update wasn't random chaos. It was Google getting more specific about what makes a good e-commerce page. More content, better reviews, faster load times, clean technical implementation, and genuine expertise.
None of that is revolutionary. But it's all measurable, and it all matters now in ways it didn't six months ago.
Sites that treat product pages like content—not just transactional endpoints—are winning. Sites that optimize for Google's checkboxes without improving the actual user experience are losing.
The gap between those two approaches just got a lot wider.
