Most online stores make the same SEO mistakes. Not obscure, hard-to-diagnose problems; the kind of issues that show up in the first twenty minutes of any e-commerce SEO audit. Title tags that say nothing useful. Product pages with thirty words of copy. Category pages with no content at all.
This ecommerce seo checklist covers ten of those recurring problems. Each one is fixable, most without a developer, and together they account for the majority of organic traffic that stores leave on the table. If your store has been live for more than six months, at least half of these will apply.
In short: The biggest e-commerce SEO problems are not technical mysteries. They are missing title tags on product pages, thin or copied descriptions, empty category pages, no schema markup, slow mobile speeds, weak internal linking, no blog content, missing Google Merchant Center setup, absent image alt text, and no strategy for out-of-stock pages. Fix these ten and most stores will see measurable improvement in organic traffic.
1. Missing or Duplicate Title Tags Across Product Pages
Most e-commerce platforms auto-generate title tags from the product name. A product called "Classic Leather Wallet" gets a title tag that says exactly that, nothing more. No brand, no modifier, no keyword that a real person would search for.
The problem gets worse at scale. If you sell thirty wallets, you now have thirty pages where the only SEO-relevant element is a generic product name. Shopify and WooCommerce both default to this behaviour. The platform creates the tag; nobody checks it; Google sees a site full of pages that barely differentiate themselves.
Every product page needs a unique, keyword-informed title tag. That means adding modifiers: the material, the colour, "for men" or "for women", the brand name if it has search volume. A title tag is your page's first impression in search results. When it reads like an internal inventory label, nobody clicks.
If you are on Shopify, this is one of the platform's most common SEO issues. The workaround is manual editing or a plugin that lets you set title tag templates at the collection level.
2. Thin or Copied Product Descriptions
Manufacturer descriptions are the default for most stores that do not write their own copy. The problem: hundreds of other stores selling the same product use the exact same text. Google treats this as duplicate content, and it has no reason to rank your version over anyone else's.
Even original descriptions often fall short. A product page with two sentences ("Beautiful cotton shirt. Available in three colours.") gives Google almost nothing to work with. There are no keywords, no context, no reason for a search engine to understand what the page is about.
The minimum viable product description is around 80 to 150 words of unique copy. Cover what the product does, who it is for, what makes it different from similar products. This is not marketing copy for the sake of it; it is the text that tells Google this page deserves to rank. Stores with at least 50 words of unique description per product consistently outperform those without.
3. Category Pages With No Content
Category pages are where the real commercial keywords live. When someone searches "buy running shoes online" or "organic dog food", Google wants to show a page that lists relevant products and explains what the category contains. Most stores show a product grid and nothing else.
Adding 150 to 250 words of unique intro text on a category page is one of the highest-impact SEO improvements any store can make. Describe what the category includes, what customers typically look for in this product type, and why your selection matters. This is the text that helps Google understand the page's topic, and it gives you a natural place to include the keywords your customers actually search for.
This recommendation comes directly from what we check in our 46-point audit framework. It is one of the simplest changes, yet the one most stores have never done.
4. No Product Schema Markup
Product schema (also called structured data) tells Google the price, availability, review rating, and stock status of your products in a machine-readable format. When implemented correctly, it enables rich results in search: star ratings beneath your listing, the price displayed before anyone clicks, whether the item is in stock.
Roughly half of e-commerce sites still do not implement product schema. That means half of all stores are missing out on the enhanced search listings that directly increase click-through rates. The visual difference in search results is significant; a listing with star ratings and a price simply draws more attention than a plain blue link.
Most modern platforms support schema through plugins or built-in settings. Shopify has basic product schema by default, but it often needs extending. WooCommerce requires a plugin. Magento has extensions. The implementation is a one-time effort with ongoing returns.
5. Slow Page Speed on Mobile
Around 75% of e-commerce traffic comes from mobile devices. If your product pages take four or five seconds to load on a phone, you are losing visitors before they even see what you sell.
Uncompressed images are the most common culprit. A single product photo saved as a full-resolution JPEG can be 2 to 5 MB. Multiply that by six images per product page and the page weighs more than most people's patience. Convert images to WebP format, enable lazy loading so off-screen images do not load until the user scrolls to them, and address any render-blocking CSS or JavaScript that delays the initial page render.
Google's PageSpeed Insights is the free diagnostic tool for this. Run your homepage and your highest-traffic product page through it. The report will tell you exactly what to fix, ranked by impact. This is one area where store owners want "do this" rather than "understand this algorithm", and the tool delivers exactly that.
6. Ignoring Internal Linking Between Products and Categories
Internal links are how search engines understand the structure of your site. They are also how authority flows from your homepage (which usually has the most backlinks) down through category pages to individual products. Without deliberate internal linking, many product pages end up as dead ends.
Related product sections, breadcrumb navigation, and "customers also bought" widgets are all forms of internal linking. Most stores either lack these entirely or generate them automatically without any SEO consideration. A breadcrumb trail that reads Home > Products > SKU-4892 is not useful to anyone.
Proper internal linking distributes ranking authority from high-authority pages to the ones that need it. It also helps users find related products, which is good for both SEO and conversion. Category pages should link to their top products. Product pages should link back to their parent category and to related items. This is one of the first things an e-commerce SEO audit checks, because it affects how authority flows through the entire site.
7. No Blog or Content Strategy
Without a blog, your store only competes for bottom-of-funnel commercial keywords: "buy [product]", "[product] price", "[brand] review". These are the most competitive terms in e-commerce, and you are competing against Amazon, major retailers, and every other store in your niche.
A blog is how a store captures informational and top-of-funnel traffic. Buying guides, comparison articles, how-to content, and educational posts bring people to your site before they are ready to buy. Some of those visitors will come back when they are. More importantly, that content builds topical authority; it tells Google your site is a genuine resource in your product category, not just a checkout page.
The content does not need to be ambitious. One well-researched article per month, targeting a question your customers actually ask, is enough to start building a content footprint that compounds over time. Stores that treat their blog as an afterthought are leaving their entire top-of-funnel strategy to competitors.
8. Not Submitting Products to Google Merchant Center
Google Shopping results appear for most product-related searches. Those product cards with images, prices, and store names that sit at the top of the results page are not all paid ads. Google offers free product listings through its Merchant Center, and any store with a product feed can appear there.
Stores that have not set up Google Merchant Center are missing free visibility in the most prominent position on product search results. Setting it up requires creating a product feed (most platforms can generate one automatically) and verifying your domain. The process is straightforward, and the ongoing maintenance is minimal once the feed is connected.
This is not a ranking factor in the traditional sense, but it is a visibility channel that costs nothing and reaches people who are actively searching for products you sell.
9. Missing Alt Text on Product Images
Product images are a store's richest visual asset, yet most have no alt text at all. Alt text serves three purposes: it tells screen readers what the image shows (accessibility), it helps Google understand the image content (SEO), and it makes your products eligible to appear in Google Image Search, which is a genuine traffic source for e-commerce.
The fix is simple. Every product image should have a descriptive alt tag that says what the image shows. "Red leather crossbody bag, front view" is useful. "IMG_4892.jpg" is not. "Red leather crossbody bag best price buy now free shipping" is keyword stuffing and helps nobody.
Write alt text as if you are describing the image to someone who cannot see it. That is literally what it is for. The SEO benefit follows naturally from doing it well.
10. No Out-of-Stock Page Strategy
Products come and go. Seasonal items sell out, lines get discontinued, suppliers change. Without a strategy, those product pages return 404 errors and all the SEO value they accumulated disappears.
There are three sensible approaches. First, keep the page live with a notice that the product is unavailable, and show similar alternatives. This is best for products that may return to stock. Second, 301 redirect the URL to the parent category page. This preserves the link equity and sends visitors somewhere useful. Third, return a 410 (gone) status code for products that are permanently discontinued and have no natural redirect target.
The worst option is doing nothing, which is what most stores do. A site with hundreds of 404 pages from old products signals neglect to both search engines and customers. Having a documented process for handling out-of-stock URLs is a small operational detail that separates stores that take SEO seriously from those that do not.
Frequently Asked Questions
How often should an online store audit its SEO?
A thorough audit once a year is a reasonable baseline. If you are making significant changes to your site, adding product lines, or redesigning, run one before and after. Quarterly spot-checks on the biggest issues (page speed, crawl errors, broken links) are worth the thirty minutes they take.
What is the most common SEO mistake for e-commerce sites?
Thin or duplicate product descriptions. It is the single issue that affects the most pages on the most sites. Fixing it is tedious because it requires writing unique copy for every product, but the impact is proportional to the effort.
Do I need a blog for my online store?
Not on day one, but eventually yes. A blog is how you capture informational traffic and build topical authority in your product category. Without one, you are only competing for the most expensive, most competitive commercial keywords. Start with one article per month targeting questions your customers actually ask.
Does Shopify handle SEO automatically?
Shopify handles the basics: it generates sitemaps, provides canonical URLs, and includes basic product schema. But it also creates problems: rigid URL structures, auto-generated title tags, limited control over robots.txt, and duplicate content from collection filtering. Shopify gives you a starting point; it does not give you a strategy. We covered the specifics in our article on Shopify SEO problems.
How long does it take to fix e-commerce SEO issues?
It depends on the store's size and the severity of the issues. Quick wins like adding alt text and fixing title tags can be done in a few days. Content work (product descriptions, category page copy, blog articles) takes weeks to months depending on how many pages need attention. Technical issues like page speed and schema markup are usually a one-time project that takes a developer a few days.
If you are not sure where your store stands on these ten points, that is exactly what an e-commerce SEO audit is for. A few days of analysis now saves months of guessing about what is actually holding your store back.
