Backlinks from other websites get most of the attention in search marketing, partly because they are hard to earn. The links a site places between its own pages are less glamorous, yet they are entirely under the owner's control and influence how both visitors and search engines move through the content. A site with strong articles but weak internal connections often underperforms, simply because its best pages are hard to reach.
What internal links do
Internal links serve three overlapping purposes. They help crawlers discover pages and understand how topics relate. They pass some of the authority a page has earned on to the pages it links to. And they guide readers to the next useful piece of information, which keeps them on the site longer and makes it more likely they find what they came for.
| Aspect | Internal links | Backlinks |
|---|---|---|
| Who controls them | The site owner | Other site owners |
| Main job | Structure, discovery and navigation | Signals of trust and authority from outside |
| Effort to add | Low, once a plan exists | High and often slow |
Building a sensible structure
The most reliable approach groups content into topics. Each topic has a central page that covers it broadly, sometimes called a hub or pillar, and a set of supporting articles that each go deeper on one question. The hub links to every supporting article, the articles link back to the hub, and closely related articles link to each other where it genuinely helps the reader.
Depth matters too. Important pages should be reachable within a few clicks of the homepage. If a key service page sits five or six levels down, both visitors and crawlers may treat it as less important than it is.
Specialist firms such as Agence SEO Zenith often start an engagement with exactly this kind of structural review, mapping how pages connect before recommending new content, which is a useful model for any site owner.
Running a quick audit
- Find orphan pages. Use a crawler or your sitemap to list pages that no other page links to, then connect them or retire them.
- Check click depth for priority pages and add links from higher-level pages where they sit too deep.
- Review anchor text. Descriptive phrases such as "guide to commercial leases" tell readers and search engines more than "click here".
- Fix broken links and update links that point through redirects.
- Refresh older posts with links to newer articles on the same topic, so link equity flows in both directions.
Mistakes to avoid
Over-optimisation is the most common trap. Using the exact same keyword-rich anchor dozens of times looks unnatural and adds little for readers. Stuffing every paragraph with links has a similar effect, making it harder to see which ones matter. Sitewide footer links to every page dilute the signal rather than strengthening it. Finally, linking only from new content to old, and never the reverse, leaves fresh articles isolated. A calm, reader-first approach, where each link answers the question "what would someone want to read next?", tends to serve both people and search engines well.
Odd jobs
Quick wins around the house and the drive
Little jobs that save a headache later on.
Date your money check
Write the date on every net worth or budget sheet so next year's version compares fairly.
Keep a gauge in the glovebox
A personal tire gauge costs little and is often steadier than a forecourt one.
Restart before you ring
Many picture freezes clear once the router and the box have been switched off and on again.
Read the door placard
Your car's correct tire pressures come from the maker, not from the sidewall.

Rules of thumb behind our checks
A few principles that shape what reaches the page.
A vehicle handbook outranks any general car guide, ours included.
Credit scoring differs between countries and between agencies, so no single score explains every file.
Book values on a balance sheet can sit a long way from what an asset would actually sell for.
Apps and set-top boxes rearrange their menus often, which makes the provider's own help pages the freshest source.
A figure that depends on your lender, your car or your country is better looked up at the source than copied from an article.
