Internal links are easy to add and just as easy to misuse.
A blogger may publish hundreds of articles while relying almost entirely on category pages, navigation menus, and automated “related posts” sections to connect them. Another site may add dozens of keyword-heavy links to every page in the hope of improving rankings.
Neither approach is a strong internal linking strategy.
Useful internal linking is deliberate. Important pages receive links from relevant content. Related articles form logical groups. Anchor text explains where a link leads. New posts are connected to older resources, and older content is regularly updated to point toward newer pages.
Internal links can also help search engines discover pages. Google says links are an important way it finds new pages and that every page you care about should have a link from at least one other page on your site. (developers.google.com)
For bloggers and publishers, that makes internal linking both an SEO task and a site-navigation task.
What Is Internal Linking?
An internal link is a hyperlink from one page on your website to another page on the same website.
For example, suppose you have an article about starting a blog and another about choosing web hosting.
Inside the blogging guide, you might write:
“Before installing WordPress, choose a web hosting provider suitable for your website.”
The linked text sends the reader to your hosting guide.
That is an internal link.
Internal links differ from external links, which point to another website.
They can appear in:
- article body content
- navigation menus
- breadcrumbs
- category pages
- sidebars
- footers
- related-post sections
All of these links can serve a purpose, but contextual links placed naturally inside relevant content are particularly useful because the surrounding text explains why the destination matters.
Why Internal Links Matter for SEO
Internal linking serves several functions at once.
It helps search engines discover pages
Google says links are used to find new pages to crawl. If you publish an article but nothing else on your site links to it, discovery can become more difficult. (developers.google.com)
This is one reason newly published articles should not remain isolated.
It helps explain relationships between pages
Links provide context.
If several detailed articles about keyword research all link to a broader keyword research guide, the structure makes the relationship between those resources clearer.
It directs readers toward useful next steps
A reader who has just learned how to choose a blog niche may naturally want to know how to research keywords next.
A well-placed internal link helps that person continue without returning to Google.
It helps you emphasize important content
Not every page on a website has equal importance.
A detailed service page, commercial comparison, pillar article, or high-value guide may deserve links from several relevant pages.
Internal linking gives you a practical way to ensure important URLs are not buried deep inside the site.
Start With a Hub-and-Spoke Structure
A simple way to organize internal links is the hub-and-spoke model.
The hub is a broad resource covering a major topic.
The spokes are narrower articles that examine parts of that topic in more detail.
Suppose you publish a blog about SEO.
Your hub could be:
Keyword Research for Beginners
Supporting spokes might include:
- How to Find Long-Tail Keywords
- How Keyword Difficulty Works
- Search Volume Explained
- How to Research Competitor Keywords
- Best Free Keyword Research Tools
- How to Map Keywords to Blog Posts
The hub should link to the relevant supporting guides.
Supporting guides can link back to the hub when doing so helps readers understand the broader subject.
They can also link to one another.
An article about keyword difficulty might naturally point to the competitor-research guide when explaining how to evaluate current ranking pages.
This creates a network rather than a one-way chain.
Use Contextual Links Inside Your Articles
Contextual internal links are links placed within the main content of a page where they are relevant to the surrounding discussion.
For example:
“Before choosing individual keywords, create a broader blog content strategy so you know which subjects deserve priority.”
That link makes sense because the destination expands on the idea being discussed.
Compare it with inserting this at the end of an unrelated paragraph:
“Also read: Blog Content Strategy.”
Both are technically internal links, but the first provides much stronger context.
Google recommends linking to internal resources in context and says the words surrounding a link help provide additional meaning. (developers.google.com)
Add links when a reader would reasonably benefit from opening another resource.
Do not turn every paragraph into a collection of hyperlinks.
Write Descriptive Anchor Text
Anchor text is the clickable text used for a link.
Google recommends anchor text that is descriptive, reasonably concise, and relevant to both the page containing the link and the destination. (developers.google.com)
Generic anchor text provides little information.
Weak:

Better:
keyword research for beginners
how to choose a profitable blog niche
WordPress hosting comparison
A reader should have a reasonable idea of what will open before clicking.
Do you need exact-match anchor text?
No.
You can use descriptive variations.
Suppose the destination targets:
how to start a blog
Your internal links might use:
- how to start a blog
- starting your first blog
- complete blogging setup guide
- beginner guide to creating a blog
The wording should fit the surrounding sentence.
Avoid forcing an exact target keyword everywhere.
Google specifically advises site owners to write anchor text naturally and avoid cramming related keywords into links. (developers.google.com)
Find and Fix Orphan Pages
An orphan page is a page that has no internal links pointing to it from other crawlable pages on your site.
The URL may exist in your sitemap. Google may even have indexed it. Readers could reach it from search results.
But from the website itself, there is no obvious path to the page.
For example, imagine you publish:
example.com/email-marketing-checklist
You add it to your XML sitemap but never link to it from your email marketing articles, category pages, navigation, or other content.
That page is effectively isolated.
Google recommends ensuring that every page you care about receives a link from at least one other page on your site. (developers.google.com)
How to find orphan pages
You can identify potential orphan pages by comparing different URL sources:
- XML sitemap URLs
- CMS page and post lists
- Google Search Console pages
- analytics landing pages
- site-crawl results
If a URL appears in your sitemap or CMS but does not appear in a crawl of your internal links, investigate it.
Then decide whether the page should:
- receive relevant internal links
- be consolidated with another article
- redirect somewhere more useful
- remain intentionally isolated
- be removed
Not every orphan URL needs to become important content.
Keep Important Pages Within Reasonable Link Depth
Link depth describes how many clicks it takes to reach a page from another starting point, commonly the homepage.
For example:
Homepage → Blog → SEO → Technical SEO → Canonicalization → Article
That page sits deeper in the site than:
Homepage → SEO Guides → Article
There is no universal rule saying every article must be exactly two or three clicks from the homepage.
The practical goal is simpler: important content should not require users or crawlers to navigate through an unnecessarily complicated chain of pages.
Google recommends logical site organization and emphasizes the importance of links for discovery. (developers.google.com)
For a typical blog, good category pages, pillar pages, navigation, and contextual internal links usually keep important content reasonably accessible.
If an article can only be reached by clicking through five old archive pages, it probably deserves a better route.
Link From Strong Older Content to New Articles
A common blogging habit is:
- publish article
- add links from it to older posts
- never touch the old posts
That leaves half of the internal-linking opportunity unused.
When you publish something new, identify older articles that should now link to it.
Suppose you publish:
How to Build an Internal Linking Strategy
Search your existing content for articles covering:
- SEO basics
- blog content strategy
- topical authority
- on-page SEO
- site structure
- keyword mapping
Several of those pages may contain passages where the new internal-linking guide would genuinely help readers.
Add the link there.
This creates inbound internal links to the new page immediately instead of waiting months for future posts to reference it.
Update Old Content as Your Site Expands
Internal linking should be part of content maintenance.
A two-year-old article may have been well linked when it was published but miss dozens of useful pages you created afterward.
During a content update, check:
- Are there newer articles this page should reference?
- Are existing internal links still relevant?
- Do any links redirect?
- Are any destinations deleted?
- Is there a stronger page that should receive the link instead?
- Is an important section missing links to deeper resources?
Updating links can improve the usefulness of an old article without rewriting the entire piece.
It can also prevent unnecessary redirect chains when URLs change.
Google recommends updating internal links to point directly to new URLs after site migrations rather than relying indefinitely on redirects. (developers.google.com)
Prioritize Internal Links to Important Pages
You do not need to distribute internal links equally across every URL.
Some pages deserve greater emphasis.
These might include:
- pillar guides
- product comparisons
- service pages
- category resources
- high-converting affiliate articles
- important evergreen tutorials
- pages ranking close to page one
- articles receiving strong search impressions
Suppose you run a blogging site and your web hosting comparison generates affiliate revenue.
It would make sense to link to that page naturally from articles such as:
- How to Start a Blog
- How to Create a WordPress Website
- WordPress.com vs WordPress.org
- Blogging Tools for Beginners
- How Much Does It Cost to Start a Blog?
It would not make sense to force hosting links into unrelated posts simply because the hosting page is commercially valuable.
Relevance still matters.
Use Internal Links Across Topic Clusters
Topic clusters become far more useful when their pages actually connect.
Suppose you have a cluster about blogging:
Hub: How to Start a Blog
Supporting pages:
- How to Choose a Blog Niche
- How to Choose a Domain Name
- Best Web Hosting
- How to Install WordPress
- How to Write Your First Blog Post
- How to Get Traffic to a New Blog
The hub can link to all of these resources at the relevant stages.
The hosting guide may link to WordPress installation.
The first-blog-post guide can link to keyword research and content strategy.
The traffic guide can link to SEO and internal linking articles.
A well-built cluster should feel like a connected library rather than several articles that happen to discuss similar subjects.
Do Not Obsess Over a Specific Number of Internal Links
There is no universal ideal such as:
“Every blog post needs exactly five internal links.”
Google explicitly says there is no magical ideal number of links a page should contain. (developers.google.com)
A 600-word troubleshooting guide may only need a few.
A 5,000-word pillar guide could reasonably contain many more.
Use as many as are genuinely helpful.
If you are adding a link simply because you feel the article has not reached its quota, you probably do not need it.
Common Internal-Linking Mistakes
Using generic anchor text everywhere
“Click here” and “read this” provide little context.
Use descriptive text.
Over-optimizing anchors
Do not repeat the exact target keyword in every link.
Natural variations are easier to read and less forced.
Linking unrelated pages
A commercial page should not receive links from every article simply because it makes money.
The relationship between the pages should make sense.
Leaving new content orphaned
Every important new post should receive relevant internal links from existing content.
Only linking from new posts to old posts
Go back and add links from older pages to useful new resources.
Adding too many links close together
Google recommends avoiding chains of links placed immediately beside one another because surrounding text helps establish context. (developers.google.com)
Relying only on menus and footers
Navigation links matter, but contextual article links can communicate much more specific relationships.
Linking through unnecessary redirects
If page A permanently moved to page B, update internal links so they point directly to page B rather than continuing to send readers through the old URL.
Linking everything to the homepage
Your homepage is already likely to receive many internal links.
Deep articles, pillar pages, and important commercial resources usually need more attention.
A Simple Internal Linking Workflow for Bloggers
You can turn internal linking into part of your publishing process.
When creating a new article:
- Identify three to five existing pages it could link to naturally.
- Add descriptive contextual links while writing.
- Find older articles that should link to the new page.
- Add the new article to the relevant topic hub or category.
- Confirm that the page is reachable through normal crawlable links.
- Review important internal links whenever you update the article.
Every few months, audit the wider site for:
- orphan pages
- broken internal links
- redirecting links
- important pages with very few internal links
- outdated anchor text
- topic clusters with weak connections
- pages buried unnecessarily deep in the site
For large blogs, crawling tools can automate much of this analysis. Smaller websites can often perform the same review using a sitemap, Search Console, and a simple spreadsheet.
A good internal linking strategy should make the website easier to navigate before it makes the website look more optimized.
Connect pages because they genuinely belong together. Give important resources clear paths from related content. Use descriptive anchor text. Fix orphan pages. Update old articles as new content appears, and organize major topics so readers can move naturally between broad guides and detailed supporting resources.
When those habits become part of your normal publishing workflow, internal linking stops being a cleanup task and becomes part of the architecture of the site itself.
