Technical SEO for Ecommerce: Best Practices

To run a successful online store, you’ll need more than just good quality products and a brand that draws you in. If search engines can’t crawl and index your website, you’re items will stay invisible to potential buyers.

One of the biggest reasons why this might happen is because of technical issues. To avoid this, we’ve provided a checklist to help guide you through technical SEO best practices for UK e-commerce.

What is Technical SEO for E-commerce?

Technical SEO means that search engines can discover, understand and display your website to people searching for relevant terms. It involves a three-stage process:

• Crawling – This is where search engine bots follow links to discover pages across the internet
• Indexing – Search engine algorithms then store, analyse and organise page content
• Rendering – Search engines execute code to render page content as a user would see it

For e-commerce business owners, the process becomes a little more complex. Online stores often feature dynamic and large product catalogues, various navigation filters, product variants and frequent stock changes. If the technical structure of your website isn’t up to par, search engine bots can get confused with endless URL combinations and miss important product updates.

Technical SEO looks out for a number of things, including content quality, accessibility and user experience, while supporting visibility of your pages. But its worth remembering that this doesn’t automatically guarantee top rankings or instant sales.

Best Practices for Technical SEO

Follow these fundamental technical SEO strategies for your online storefront.

Improve Crawlability and Indexing

Search engine bots only have a handful of time and resources to spend on your site. If crawlability is poor, key revenue-generating pages could easily be ignored.

• Use Google Search Console’s URL Inspection tool and the Page Indexing Report to make sure your primary pages are indexable and return clean HTTP 200 status codes.
• Only include preferred and indexable URLs in your XML sitemap and ensure these updates whenever products are added, modified or removed.
• Get to know the different control mechanisms. Robots.txt prevents bots from crawling specific pages to save budget, and the noindex directive instructs search engines not to index a page.
• Use tags to indicate the primary version of a duplicate or similar page.
• If your store relies on JavaScript to render product descriptions or links, make certain that these are accessible in the raw HTML response or set out reliably during rendering.

Build Clear Navigation and Handle Pagination

Effective site structure makes it easier for both human visitors and search engine crawlers to navigate your website with ease.

• Include logical internal links from top-level menus to main categories, subcategories and individual products.
• Try to use descriptive URLs if it’s possible and makes sense to. Routinely audit your store for items that exist in your database but lack internal links.
• If you’re using infinite scroll, ensure there are accessible and paginated fallback URLs so crawlers can access every product.

Manage Filters and Duplicate Product URLs

The best navigation allows users to filter items by size, colour, brand or price. However, this can actually generate thousands of duplicate or low-value URL combinations. Identical content can also be created across hundreds of links.

• Select filtered pages for indexing only when there is clear search demand and unique content available.
• Use tags to point duplicate URLs back to the main category page.
• Consider restricting excessive filter combinations.

Improve Mobile Performance and Core Web Vitals

Your store’s mobile experience is connected to how effectively your pages are assessed.

• Focus on your core web vitals, including page loading speed, interactivity and visual stability.
• Compress your images, convert graphics to modern formats, remove unused scripts, plugins or tracking apps and reserve explicit width and height dimensions for images and banners.
• Test mobile browsing and checkout flows.

Add Accurate Product Structured Data

Structured data helps search engines understand product details and display rich visual attributes in search results.

• Keep your schema data aligned with the visible text on the page.
• Include reviews from customers!
• Use appropriate mark-ups for product variants so search engines can distinguish distinct offers.

Handle Stock Changes and Site Updates

If you’re an ecommerce site, then your inventory might change regularly. Having something in place for out-of-stock items and site updates prevents broken links and poor user experience.

• Keep pages for out-of-stock items live and accessible. Just reflect the status of the product in your stock.
• If a product is permanently removed and a direct replacement exists, make sure you’ve got a redirect on that page. If no replacement exists, just use a 404 Not Found page.

Monitor issues and prioritise fixes

Technical maintenance requires continuous oversight rather than setting it up and forgetting about it.

• Resolve issues in order of business impact.
• Combine analytics and audits.
• Track organic performance alongside overall conversions and revenue, and don’t forget to account for seasonal demand fluctuations.
• Spot-check pages when new products are launched, and old sellers are taken away.

Elevate your e-commerce site’s structure and technical health

Maintaining a working and technically sound e-commerce site means that search engine crawlers can index your catalogue with ease and allows prospective shoppers to more likely discover your products. But while technical SEO might provide the foundation your online store needs to succeed, it requires a level of expertise.
