Internal Links: How to Make Google Understand What Your Site Is About

When people think about SEO, they usually picture backlinks, keywords, meta descriptions. All of that matters. But there’s one element that’s completely under your control—and that most small sites ignore entirely: internal links.

Internal links are the links that connect one page on your site to another page on your own site. Sounds basic. And it is. But how you use those links tells Google how your content is organized, which page is most relevant, and what your site actually does.

If you run a service site with 5 to 10 pages, this article is for you.

Why internal links matter for SEO

Google discovers new pages by following links. When Google’s bot (Googlebot) visits your site, it enters through one page and clicks the links it finds. Every internal link is a doorway for another page to be discovered and indexed.

But discovery is only part of it. Internal links also pass authority. When a page with good standing (measured by external backlinks, for example) links to another page on your site, some of that standing comes along. It’s like a recommendation: “this page here is also relevant.”

The third factor is context. The link text (called “anchor text”) helps Google understand what the destination page is about. If you link to your “Marketing Consulting” page using the text “marketing consulting,” you’re reinforcing that the page covers that topic.

The problem with small sites

On sites with many pages, internal linking happens naturally. Blog posts link to other posts, categories organize content, menus connect sections.

Small sites face a different challenge. With 5 to 10 pages, the tendency is to leave each one isolated. The home links to everything in the menu, but the internal pages don’t link to each other. The result is a flat structure where Google can’t understand hierarchy or how content relates.

Another common mistake: using generic text like “click here” or “learn more” as your link anchor. This wastes the chance to pass context. Google reads that text to understand the destination. “Click here” tells it nothing.

How to structure internal links on a service site

Let’s use a real example. Say you have a digital marketing consulting site with these pages:

1. Home
2. About
3. Service: SEO
4. Service: Google Ads
5. Service: Social Media
6. Blog (with 3 or 4 articles)
7. Contact

The basic internal link structure works like this:

The home is your central hub. It should link to every service page. Not just in the menu, but in the body text. If your home has a “Our Services” section, each service mentioned should have a link to its corresponding page.

Service pages link to each other. At the bottom of your SEO page, you could have a “Related Services” section with links to Google Ads and Social Media. This shows Google that the services are part of a cohesive set.

The blog links to service pages. If you write an article on “How to Choose Keywords,” it should link to your SEO page. The anchor text should be descriptive: “our SEO service” or “SEO consulting,” not “click here.”

Service pages link to the blog. On your SEO page, you could mention “we wrote about [keyword strategies for small businesses]” with a link to the matching article. This creates a two-way street.

Common structure (weak)

• Home links only in the menu
• Service pages isolated
• Blog doesn't link to services
• Generic anchor text

Linked structure (strong)

• Home links in body text
• Services link to each other
• Blog links to relevant services
• Descriptive anchor text

Practical rules for anchor text

The text you use in a link matters. Here are the principles:

Be descriptive, not generic. Instead of “learn more,” use “explore our SEO consulting process.” Google uses that text to understand the destination page’s content.

Vary, but stay relevant. If you always use “SEO consulting” to link to the same page, that’s fine. But natural variations work too: “our SEO work,” “search optimization,” “SEO strategy.” What matters is that the text makes sense for your reader and describes the destination.

Don’t force it. The link should appear where it fits naturally in the text. If you’re talking about social media and force a link to your SEO page without context, it feels awkward for the reader and for Google.

• Does each service page link to at least one other service page?
• Does the blog link to service pages when the topic is relevant?
• Do the anchor texts describe where the link goes?
• Does the home link to services in the body text, not just the menu?
• Do important pages get linked to from multiple other pages?

Hierarchy: which page should get more links

Not all pages have the same importance. On a service site, service pages are usually the most important for conversion. They should get more internal links.

Think of it this way: each internal link is a vote for relevance. The more pages linking to your SEO page, the more Google understands that it’s central to your site.

The home naturally gets many links (everyone links to it). But your service pages need help. If you have a blog, each article is a chance to point links where it matters.

This doesn’t mean cramming in forced links. It means writing content that naturally mentions your services and creating links when it makes sense.

What to avoid

Some common mistakes that weaken your internal link structure:

Broken links. If you changed a page’s URL and didn’t update the internal links, you’re losing authority and confusing Google. Review periodically.

Orphan pages. Pages that get no internal links are hard to discover. If Google doesn’t find them, it won’t index them. If it doesn’t index them, it won’t rank them.

Link overload in one spot. A page with 50 internal links dilutes the value of each one. Keep links relevant and reasonable in number.

Ignoring context. Linking just to link, without relation to the source page’s content, doesn’t help. Google evaluates the context around the link.

The bottom line

Internal links are the most direct way to organize your site for Google. You don’t need expensive tools or advanced technical knowledge. You need intention.

Look at the pages that matter most to your business. Usually those are your service or product pages. Then make sure other pages on your site point to them with descriptive text.

On a small site, each link counts for more. Use that to your advantage.
