Ecommerce brands often pour budget into paid ads while their organic rankings quietly deteriorate.
If you're making these common SEO mistakes, you might be actively preventing your brand from reaching its potential. We've gathered the most damaging pitfalls we see across ecommerce sites, along with practical tips to fix them. Let's get into it.
1. Leaving Optimisation Too Late
Failing to prepare is preparing to fail — and that's especially true in ecommerce. Leaving it too late to optimise your ecommerce SEO for key trading periods means missing the surge of high-intent traffic that drives your biggest revenue days. You should be planning SEO work at least three months before any key sales period: product page optimisations, targeted content, category page structure and internal linking all need time to bed in before they start influencing rankings.
Proactive planning allows you to tweak content, target high-value keywords and stay ahead of competitors who left it too late.
2. Poor URL Structure
Poor URL structure is an often overlooked aspect of ecommerce SEO. Ensuring your URLs are clean, descriptive and evergreen is paramount to long-term success. Avoid including years or session-specific references in your URLs — for example, use /sale rather than /sale-2026, and /christmas-gifts rather than /christmas-gifts-2026. This approach avoids redundancy and retains the SEO value of your pages year over year, boosting rankings as the domain ages and accrues links.
3. Low-Quality Content
Publishing large volumes of thin or rushed content is not a great idea if you want to rank and convert. Surface-level product descriptions, category pages with no supporting copy, and blog content written purely to fill a calendar will all drag down your site's quality signals. Instead, focus on creating valuable, engaging and informative content that genuinely meets the needs of your audience.
Detailed buying guides, optimised product descriptions that incorporate target keywords naturally, and user-generated content showcasing real customers are all proven tactics. High-quality content not only ranks better but also establishes trust and encourages shoppers to spend more time on your site.
4. Lack of Internal Linking
Internal linking is an SEO tactic that makes a world of difference, but is all too often neglected on ecommerce sites. By creating a clear internal linking structure between your category pages, product pages and supporting blog content, you help search engines understand your site's hierarchy and improve navigation for users.
For example, linking a buying guide to relevant product and category pages not only boosts SEO by distributing link equity, it also improves the customer journey and drives higher conversions. Audit your top-traffic pages and identify where you can add contextual internal links.
5. Poor Mobile Optimisation
Most online shopping now happens on mobile devices. A site that isn't mobile-friendly will lose customers at every stage of the funnel — and Google's mobile-first indexing means it will also lose rankings. Slow load times, difficult navigation, and unresponsive design will frustrate users and drive them to competing websites.
Make sure your site is fully optimised for mobile: fast-loading pages, a seamless checkout experience, and clear calls-to-action that work on small screens. Run your site through Google's PageSpeed Insights and use Core Web Vitals data in Search Console to identify and fix mobile performance issues.
Avoiding these five mistakes can make a significant difference to your organic performance and ecommerce revenue. If you need a helping hand, get in touch — or start with a free audit to see exactly where your site is losing ground.
