In the fast-paced world of e-commerce, visibility is everything. No matter how high-quality your products or how compelling your branding, if your website doesn’t appear in search engine results, it might as well not exist. Search Engine Optimization (SEO) is the cornerstone of online visibility, and technical SEO ensures that your site is structured and optimized in a way that search engines can efficiently crawl, index, and rank your pages.
However, many e-commerce businesses make critical mistakes—some of which are easy to overlook—that can significantly hurt their SEO performance. In fact, a comprehensive study identified 80 common technical and SEO mistakes on e-commerce websites. These mistakes span across categories like crawlability, linking, content, and security. In this guide, we’ll explore the most significant of these errors, how they impact your site, and what you can do to fix them.
The Impact of Technical SEO on E-Commerce Success
Technical SEO refers to the optimization of your website’s infrastructure to make it more accessible to search engines. For e-commerce sites, this is particularly important because of the sheer volume of pages—products, categories, brand pages, and more—that need to be indexed correctly. If your site’s technical foundation is flawed, search engines might struggle to understand what your site is about, leading to poor rankings and low traffic.
One of the most common technical issues is broken canonical URLs. Canonical tags help search engines determine which version of a page should be indexed, especially when multiple pages have similar or duplicate content. If these tags are broken or missing, search engines might index the wrong pages or spread link equity across duplicate versions, diluting your rankings.
Another prevalent issue is broken external links. While internal linking is crucial for site structure and user navigation, external linking is also important for credibility and SEO value. If your site has broken external links, it can confuse both users and search engines, leading to a poor user experience and potential SEO penalties.
Content-related mistakes are also common. For example, duplicate content—where the same content appears across multiple pages—can confuse search engines and reduce your site’s authority. The study found that 83% of e-commerce sites had duplicate content, often due to using generic manufacturer descriptions or failing to create unique product copy.
Security issues also play a role. For instance, 72% of HTTPS sites had links to HTTP pages, which can undermine the security of your site and harm your SEO. HTTPS is a ranking factor, and mixing secure and insecure content can lead to mixed content errors and a loss of trust signals.
Common Technical SEO Mistakes in E-Commerce
Let’s break down some of the most common technical and SEO mistakes in e-commerce, along with strategies to fix them. These mistakes are grouped into several categories: site structure, URL optimization, content issues, performance, security, and international SEO.
1. Poor Site Architecture and Navigation
A well-organized site structure is fundamental for both user experience and SEO. Search engines rely on site architecture to crawl and index content efficiently. However, many e-commerce websites use overly complex or inconsistent structures that make it difficult for both users and search engines to navigate.
Key Issues:
- Inconsistent URL structures: URLs that lack a clear hierarchy or use random character strings can confuse users and search engines.
- Lack of breadcrumbs: Breadcrumbs help users navigate back to previous categories or search results, improving the user experience.
- Ineffective internal linking: Poor internal linking can prevent search engines from understanding the relationship between pages and dilute the distribution of page authority.
Solutions:
- Organize URLs: Develop a clear and logical URL structure that reflects your site hierarchy. For example, use
/category/subcategory/product-nameinstead of non-descriptive strings. - Implement breadcrumbs: Use breadcrumb navigation to help users and search engines understand your site structure.
- Optimize internal linking: Create a logical internal linking structure that connects related pages and distributes link equity effectively.
2. Faceted Navigation and URL Duplication
Faceted navigation allows users to filter products by attributes such as size, color, or brand. While this can enhance the user experience, it can also lead to significant SEO issues if not managed properly.
Key Issues:
- URL duplication: Faceted navigation can create tens of thousands of unique URLs with little to no value for search engines.
- Thin content: Many of these URLs may not provide enough unique content to be worth indexing.
Solutions:
- Restrict filtering options: Limit the number of filters and combinations to avoid creating an excessive number of URLs.
- Use canonical tags: Implement canonical tags to indicate the primary version of a page when multiple URLs point to the same content.
- Optimize URLs: Ensure that URLs created by faceted navigation include meaningful keywords and avoid unnecessary parameters.
3. Mobile Optimization and Page Speed
With the rise of mobile shopping, mobile optimization has become a critical aspect of e-commerce SEO. However, many e-commerce sites neglect this area, leading to high bounce rates and lost sales.
Key Issues:
- Slow load times: A slow-loading mobile site can frustrate users and lead to high bounce rates.
- Poor user interface (UI): A non-optimized mobile UI can make it difficult for users to navigate and make purchases.
Solutions:
- Implement responsive design: Ensure your site is fully responsive and adapts to different screen sizes.
- Optimize images: Use image compression tools to reduce file sizes without sacrificing quality.
- Minify CSS and JavaScript: Reduce the size of CSS and JavaScript files to improve load times.
4. Duplicate Content and Poor Product Descriptions
As mentioned earlier, duplicate content is a major issue in e-commerce. Many sites use generic manufacturer descriptions or copy content across multiple pages, which can hurt rankings and reduce credibility.
Key Issues:
- Generic product descriptions: Using manufacturer descriptions or copying content across multiple pages can lead to duplicate content issues.
- Lack of unique content: Repetitive content doesn’t help users differentiate between products and can reduce credibility.
Solutions:
- Write unique descriptions: Create unique, keyword-rich descriptions for each product.
- Highlight benefits: Focus on the benefits of each product rather than just the features.
- Use schema markup: Implement schema markup to enhance your product listings in search results.
5. Missing or Broken Canonical Tags
Canonical tags are essential for managing duplicate content. If your site has multiple versions of the same content (e.g., different URLs for the same product), canonical tags help search engines determine which version to index.
Key Issues:
- Broken canonical URLs: If canonical URLs are broken, search engines may index the wrong version of a page.
- Missing canonical tags: If canonical tags are missing, search engines may treat duplicate pages as separate entities.
Solutions:
- Audit canonical tags: Regularly audit your site to ensure canonical tags are correctly implemented.
- Fix broken links: If canonical URLs are broken, fix them to point to the correct version of the page.
- Use 301 redirects: If you need to change a canonical URL, use 301 redirects to preserve link equity.
6. Neglecting Schema Markup
Schema markup is a type of structured data that helps search engines understand the content of your pages. For e-commerce sites, schema markup is particularly useful for product listings, reviews, and breadcrumbs.
Key Issues:
- Missing schema markup: If schema markup is missing, search engines may not display rich snippets or other enhanced search features.
- Incorrect schema markup: If schema markup is implemented incorrectly, it can provide inaccurate information to search engines.
Solutions:
- Implement product schema: Use product schema to include details like price, availability, and product descriptions.
- Use review schema: Display star ratings and customer reviews directly in search results.
- Use breadcrumb schema: Help users and search engines navigate your site with breadcrumb markup.
7. International SEO Mistakes
For e-commerce sites targeting multiple regions or languages, international SEO is crucial. However, many sites make common mistakes that can hurt their visibility in different markets.
Key Issues:
- Failing to localize content: Failing to translate content or adapt it to local cultures can reduce engagement and conversion rates.
- Incorrect hreflang tagging: Hreflang tags help search engines serve the appropriate regional content. If these tags are missing or incorrect, search engines may serve the wrong content to users.
Solutions:
- Localize content: Develop a strategy that includes translating content, using local keywords, and adapting marketing messages to fit cultural contexts.
- Implement hreflang tags: Ensure hreflang tags are correctly implemented on every page to guide search engines in serving the appropriate regional content.
- Optimize site architecture: Optimize site architecture and URL structures to accommodate multilingual and multi-regional versions of your site.
