Imagine a patient reading the teeth whitening page on your dental clinic's website. They are convinced. But the page ends there: no button to book an appointment, no sentence pointing to your prices. The patient puts the phone down and calls another clinic. Good content is not enough; visitors must be able to move from one page to the next without effort.
The same is true for Google. It explores your website by following the links between pages. If no page links to a certain page, that page exists but nobody can reach it. In this article I explain what internal linking is, how it affects your business, and how to tell whether your own site has a problem.
What is internal linking?
Internal linking simply means a link from one page of your website to another page of the same website. The "About us" item in your menu, a sentence in a blog post that says "see our services", or a "Contact us" button at the bottom of a page are all internal links. A link from someone else's website to yours is an external link, and that is not the subject here.
Think of the signs inside a building. Without signs, visitors stay in the lobby and never find the lift or the right floor. In a well-planned building, every floor and every room is signposted from somewhere.
How does it affect your business?
Internal linking has three concrete effects.
- It shortens the customer's path. Someone reading an information page can reach the related service in one click, and from there the contact or booking page.
- It helps Google find your pages. If a new service page is linked from other pages, Google notices it sooner.
- It shows which pages matter most. The pages that receive the most links tell Google "these are the important ones". If your main money-making service page is buried in a corner, that signal may be pointing at the wrong page.
None of this alone will put you in first place on Google. But it prevents the rest of your work on the site from going to waste.
Here is a small example. A hotel website has a room page, a breakfast page and a neighborhood guide article. The guide is read a lot but never links to the room page. A guest finishes reading, wonders "so where will I stay?", finds no answer and leaves. One sentence and one link at the end of the article could carry the same reader to the booking page. What I see most often on business websites is exactly this: well-written pages that lead nowhere.
How do you know if your site has a problem?
You can check the following yourself, without technical knowledge.
- Start from the home page. How many clicks does it take to reach your three most important services? More than two or three clicks can tire visitors.
- Read one blog post to the end. Is there a pointer to the related service inside or at the end of the article?
- Look for "orphan" pages. If some service or price pages cannot be reached from the menu or any other page, they are called orphan pages. Neither Google nor visitors find them easily.
- Look at the link wording. "Click here" or "read more" tells nobody where the link goes. "Get information about root canal treatment" tells both the reader and Google what the page is about.
- Try the links. A link that shows an error is the easiest way to lose a customer.
What does a good link structure look like?
Designing it is the specialist's job, but knowing what result to expect helps you.
| Page type | Links it should contain |
|---|---|
| Home page | Main service pages, contact |
| Service page | Related services, frequently asked questions, contact page |
| Blog post | The related service page, similar articles |
| Contact page | A way back to the main services |
The rule is simple: every page should point to the next step a visitor may want to take after reading. Links should sit inside natural sentences, and a page should not be crowded with them. A link in every sentence overwhelms the reader.
What a specialist does for you
An SEO specialist or whoever manages your site will usually:
- List all pages on your site and find which ones receive no links.
- Identify your money-making service pages and add links to them from related articles.
- Arrange the menu and footer links around the visitor's journey.
- Repair broken links pointing to old, deleted or moved pages.
- Keep links up to date as new content is published.
How long this takes depends on the size of the site. On a corporate site of thirty pages the first clean-up often takes a few days; a blog with hundreds of articles takes longer. After that, small additions with each new piece of content are enough. So this is not a one-off job but part of regular site care.
What should you ask the specialist?
- "Are there pages on my site that receive no links? Can I see the list?"
- "Which pages link to my most important service pages?"
- "When we add a new article or page, who adds the internal links, and when?"
- "How often do you check for broken links?"
If the answers are vague, this work is probably not being done at all.
Frequently asked questions
How many links should each article contain?
There is no fixed number. Links go where they truly help the reader. In a short article two or three are often enough; what matters is that each link is relevant.
Will adding internal links lift my site immediately?
No. Google takes time to notice changes, and the result also depends on the rest of your site. This work alone guarantees nothing, but it forms a solid foundation.
Can I do this myself?
Linking to the related service page whenever you write a new article is easy. Reviewing the whole site, ranking pages by importance and repairing broken paths takes experience.
Is changing links too often harmful?
Frequent, unplanned changes can confuse both visitors and Google. Planning once properly and then making small additions with new content is healthier.
Conclusion
If the pages on your website are not linked together, even your best service page can stay silent. Internal linking takes little effort but has a large effect. If you would like to review your site's link structure together, you can reach me through my SEO services page.
