Internal Linking Strategy for Digital Product Sites

Most people think about SEO in terms of the individual page: optimize the title, use the keyword, get backlinks. That's all important.

But they miss one of the most powerful SEO levers available to them: internal linking.

Internal links — links between pages on your own site — are how you tell Google what matters, distribute authority across your site, and guide visitors toward the pages where you want them to end up.

For a digital product site, a solid internal linking strategy can meaningfully improve rankings without creating a single new page or earning a single external backlink.

Here's how I think about it.

Why Internal Links Matter for SEO

Google's web crawlers follow links. When they crawl your site, they start from your homepage (or wherever an external link pointed to), and then follow the links they find to discover other pages.

If a page on your site has no internal links pointing to it — what SEOs call an "orphan page" — Google might not crawl it consistently, or it might crawl it but assign it less importance.

On the other hand, if a page has many internal links pointing to it from other pages on your site, Google interprets that as a signal that this page is important. It gets crawled more frequently, it passes more authority, and it tends to rank better.

Beyond Google, internal links guide real visitors. A blog reader who clicks through to your product page is a potential customer. A product page visitor who clicks through to a comparison post might have a final objection resolved. Good internal linking creates paths through your site that end in conversions.

The Three Types of Internal Links You Need

1. Site Navigation Links

These are the links in your header navigation, footer, and sidebars. They appear on every page of your site.

Because they appear everywhere, they pass a lot of signals to Google about what's most important. Your navigation should link to your most important pages: your product categories, your review pages, your blog, and maybe a "start here" page.

Don't stuff your navigation with 20 links. Keep it focused. The pages in your nav are telling Google "these are the most important pages on this site."

2. Contextual Links Within Content

These are the links embedded naturally within the text of your blog posts and product descriptions.

These are the most valuable type of internal link because they carry context. When I link from a post about "email marketing for digital sellers" to my product page for an email marketing template, Google understands that the product page is relevant to email marketing. That contextual signal matters.

The rule of thumb I follow: every blog post should include 2-3 contextual links to other relevant pages on my site. Product pages should link to relevant blog posts or comparison pages that help buyers make decisions.

3. Breadcrumb and Category Links

If your site has categories or collections, links from category pages to individual product pages — and from individual pages back to category pages — create a clear hierarchical structure that helps Google understand your site's organization.

For a digital product site with multiple categories (templates, courses, guides), this category linking structure is important for helping Google understand which products belong to which topic clusters.

My Internal Linking Strategy (Specific)

Here's the actual system I use:

When I publish a new blog post:

• I add links from that post to 2-3 existing posts on related topics
• I go back to 2-3 existing posts and add links from them to the new post
• I link from the new post to the most relevant product page (or product category)

When I add a new product:

• I find 3-5 existing blog posts that are relevant to that product and add a contextual mention with a link
• I add the product to its category page
• I create a brief "related products" or "you might also like" section if my platform supports it

Once per quarter:

• I audit my most important pages for internal links — my top-revenue products and my highest-traffic posts
• I look for opportunities to add more links pointing to those pages from less-trafficked posts
• I check for orphan pages (pages with no internal links pointing to them) and fix them

MadeThis makes this straightforward — each product page has a clean URL structure that's easy to link to, and the blog and product sections of the site are properly connected.

The "Hub and Spoke" Model for Topic Clusters

One of the most powerful internal linking structures for a content-focused digital product site is the hub-and-spoke model.

Here's how it works:

• Hub post: A comprehensive, in-depth post on a broad topic (e.g., "Complete Guide to Selling Digital Products on Google")
• Spoke posts: Shorter, more specific posts that dive deep into subtopics (e.g., "How to Write Product Descriptions That Rank," "Long-Tail Keywords for Digital Products," "How to Rank a Product Page Step-by-Step")

The spoke posts all link back to the hub post. The hub post links out to all the spoke posts. This creates a tightly linked cluster that Google recognizes as topically authoritative.

I'm using this structure across the SEO cluster on this blog — you'll notice posts in this cluster link to each other. That's intentional.

The Link Text Matters Too

The text you use for your link (called "anchor text") gives Google additional context about what the destination page is about.

"Click here" tells Google nothing. "Digital product SEO guide" tells Google the destination page is about digital product SEO.

Use descriptive anchor text that includes relevant keywords when it makes sense naturally. Don't force it — but don't default to "click here" or "learn more" when a more descriptive phrase is available.

Common Mistakes to Avoid

Linking to the same page too many times. After 3-4 internal links to the same page, the SEO value of additional links diminishes significantly. You don't need to link to your most popular product in every single post.

Using the same anchor text for all links to a page. Vary your anchor text naturally. "Digital product SEO," "SEO for digital sellers," "how to rank your products" — all these can point to the same page without looking manipulative.

Ignoring product pages. Many people build good internal linking for their blog content but forget to link contextually to their actual products. Every relevant blog post should have at least one link to a product or product category.

Start Simple

If you're just getting started, don't overthink this. Follow two rules: every new post links to 2-3 existing posts, and every new post links to at least one product page.

Do that consistently for 6 months and your site's internal link architecture will be dramatically better than most of your competitors'.
