Internal Linking for Online Stores: A Practical System

Ecommerce internal linking is the system of links between pages on your own store: menus, breadcrumbs, category links, related products, guides linking to categories and categories linking back to guides. Good internal links help shoppers move naturally from inspiration to the right product, and help search engines discover every page and understand which ones matter most. Many stores leave internal links to chance, which leaves important categories under-linked and useful products hard to find. A deliberate, simple system fixes that and often lifts rankings for the pages that sell, without any new content or advertising spend.

Why internal links matter

Internal linking can sound like a purely technical task, but it starts with a very human question: where would a shopper want to go next? For shoppers, links are the paths through your store. A shopper reading a guide to choosing running shoes should be one click from the right category. A shopper on a product page should see the accessories that go with it. When these paths are missing, shoppers search, scroll or leave.

Internal links are also one of the few ranking factors entirely under your control. You cannot force other websites to link to you, but you can decide how your own pages support each other. For search engines, internal links do three jobs. They help crawlers discover pages, they indicate how important each page is, and they describe what each page is about through the link text. Google's documentation on making links crawlable explains how search engines follow them. A product that no page links to may never be found; a category linked from the menu, related categories and several guides is clearly important.

Links also pass a share of authority from page to page. When other websites link to one of your guides, internal links from that guide help some of that value reach the categories and products it mentions. A well-linked store spreads the benefit of every external link more widely.

The layers of an ecommerce internal linking system

Most of these layers are set once in your theme and then work automatically. The layers that need ongoing attention are product relationships and content links, because they depend on decisions made every time something new is added. Each layer has a role. Problems arise when one layer tries to do everything, such as a footer with hundreds of links, or when a layer is missing, such as guides that never link to products.

Linking categories well

Categories are usually your most valuable search pages, so they deserve strong internal links. They match broad, high-volume searches, and they lead shoppers to many products at once, so every link to a category does double duty.

• Include your most important categories in the main menu with clear names.
• Link from parent categories to subcategories with descriptive text and images.
• Link sideways between closely related categories, such as "Running shoes" and "Running socks".
• Link from the home page to top categories with words, not only images.
• Link from guides to the categories they discuss.

Think about priority. If a category brings a large share of your revenue, it should be easy to reach from almost anywhere relevant on the site. A seasonal or niche category can be linked more selectively. Our guide to category page SEO explains how these links support rankings.

Linking products well

In large catalogues, some products are linked only from page five or six of a category, which crawlers and shoppers rarely reach. Product pages are often the deepest pages in a store and the hardest for crawlers to reach. Help them by:

• Making sure every live product is linked from at least one category.
• Showing related and complementary products, chosen for relevance rather than at random.
• Linking variants clearly, so shoppers can move between colours or sizes.
• Linking from guides and comparisons to the specific products mentioned.
• Featuring new and seasonal products from the home page or relevant categories.

Related product rules deserve care. Automated "customers also bought" blocks are convenient, but they sometimes show odd combinations or the same few best sellers everywhere. Review them for your top products, and set manual relationships where accuracy matters, such as accessories that must be compatible.

Connecting content and commerce

This is where many stores leave the most value on the table. Guides and blog posts attract visitors who are researching. Internal links turn that research into shopping. A guide on choosing a mattress should link to the mattress categories and to specific models it describes. In return, the mattress category can link to the guide for shoppers who want help choosing.

Place links where readers would naturally want them: after explaining a type of product, or when comparing options. Links buried at the bottom of long articles are rarely clicked. This two-way linking helps both pages. The guide gains relevance and authority from being connected to commercial pages; the category gains from links in useful content. Our guide to ecommerce content marketing explains how to plan content around customer questions.

Anchor text that helps

The words you choose for links matter more than many store owners realise. Anchor text is the clickable text of a link. It tells people and search engines what to expect.

• Use descriptive text, such as "waterproof walking boots", rather than "click here".
• Vary the wording naturally; there is no need to repeat the exact same phrase every time.
• Keep it honest: the destination should match what the text promises.
• Avoid stuffing keywords into links unnaturally.

Image links need care too. When a category is linked with an image, the alt text acts like anchor text, so describe the destination clearly, such as "Women's running shoes".

Auditing your internal links

Even a well-planned link structure drifts over time. Stores change constantly, and links decay as products sell out, categories are renamed and old campaigns end. Audit regularly with a crawling tool and Search Console:

1. Find orphan pages: pages with no internal links, often old products, landing pages or guides.
2. Fix broken links to deleted products or categories.
3. Update links to redirects so they point straight to the final page.
4. Check link depth: important products should be reachable within a few clicks.
5. Review links to key categories: do your most important pages receive enough links?

Keep the audit results, so you can compare them next time and see whether the structure is improving. Fix the most important problems first: orphan pages with search value, broken links on high-traffic pages and weak links to top categories.

Our technical SEO checklist includes these checks among other technical health tasks.

Internal links during redesigns and migrations

Redesigns and platform moves are when internal linking most often breaks. Menus get simplified, category pages lose their introductions, related product blocks disappear and old guide links point to URLs that no longer exist.

• Record the current structure before changes: which pages link to your top categories and products.
• Preserve important links in the new design, especially from the menu, home page and guides.
• Update every internal link to new URLs, rather than relying on redirects.
• Crawl the new site before launch to find orphan pages and broken links.
• Compare link counts to key pages before and after the change.

Agree the new link structure as part of the design brief, not as an afterthought during testing. A redesign that removes links to an important category can quietly cost it rankings, even if every redirect is in place. Our guide to migrating without losing SEO covers the wider process.

Building linking into everyday work

Internal linking works best as a habit rather than an occasional project.

• When adding products: check they appear in the right categories and that related products are set.
• When publishing guides: link to the relevant categories and products, then add a link back from those pages to the guide.
• When launching a new category: link to it from the menu or parent category, related categories and any relevant content.
• When discontinuing products: update links and set up redirects at the same time.
• Every quarter: run a crawl, fix broken links and review links to your most important pages.

Make one person responsible for internal linking, even part-time, so it does not fall between the content, merchandising and development teams. A short checklist in your content and merchandising routines prevents most problems. It takes minutes each time and saves hours of clean-up later, when problems have built up across hundreds of different pages.
