What internal link SEO means
When a post about winter boiler care links to your boiler repair service page, that is an internal link.
When a buying guide in your store links to a product, that is an internal link too.
Internal link SEO is the practice of adding these links on purpose, in the right places, with the right words, so both readers and search engines understand your site better.
Why internal links matter so much
Internal links do three jobs at once.
- They help readers. A person who finishes one answer can click to the next helpful page.
- They help search engines find your pages. Search engines follow links, so a page with no links pointing to it is hard to discover.
- They show what matters most. Pages that many of your posts link to look important, and that can help them rank.
For a small business, the pages that matter most are usually your services, your products and your contact or booking page. Internal links point attention there.
Think of your site like a small town
Picture your website as a small town. Your home page is the main square. Your service or product pages are the big shops. Your blog posts are the side streets.
Good towns have clear signs. From any side street you can find your way to the big shops.
Internal links are those signs. Without them, visitors get lost on a side street and leave.
Every post should link out and be linked to
Each blog post needs two kinds of links.
- Links out from the post to related posts and to the right service or product page
- Links in to the post from older posts on the same topic
New posts often get the first kind and forget the second. When you publish something new, go back to two or three older posts and add a link to it.
Pick the right page to link to
Ask a simple question. After reading this paragraph, where would a helpful shop assistant send the reader next?
If the paragraph talks about a problem you solve, link to the service that solves it. If it talks about a product type, link to that product or collection.
If it mentions a topic you covered in depth before, link to that guide.
Use clear anchor text
Anchor text is the clickable word or phrase. It should tell the reader, and search engines, what the next page is about.
Good anchor text describes the page. For example, "emergency roof repair" or "how to choose running shoes".
Weak anchor text says nothing. "Click here" and "read more" give no clue about the next page.
- Use a short phrase that matches the topic of the target page
- Vary the wording a little across posts, so it reads naturally
- Never stuff the same exact phrase into every sentence
Place links inside the text
Links inside a helpful sentence work better than a long list at the bottom of the page.
Readers click links that appear right when they want more information. Put the link where the question comes up.
A small list of related posts at the end is fine as an extra, but it should not replace links in the text.
Keep the number reasonable
There is no magic number. A typical post of a thousand words or so might have a handful of internal links.
Add a link when it truly helps. If every second word is blue, readers stop trusting the links.
Build topic clusters
A topic cluster is a group of posts about one subject, all linked to one main page.
Say you run a dental clinic. Your main page is about teeth whitening. Around it you write posts on whitening at home versus in the clinic, how long whitening lasts and whitening for sensitive teeth.
Each small post links to the main whitening page, and the main page links back to each post. Search engines see a clear, complete picture of the topic.
Topic clusters are one of the best ways for a small site to show it knows a subject well.
Link to your money pages
Money pages are the pages where people book, call or buy. Many blogs forget them.
Make sure useful posts point to them naturally. A post about signs of a leaky roof can end with a link to your roof repair page.
For stores, link buying guides to the exact products and collections they mention. Our Shopify blog automation page shows how that works for stores.
Find and fix broken links
Over time pages move, products sell out and old posts get deleted. Links to those pages break.
Broken links frustrate readers and waste the attention you worked to earn.
Every few months, check your site for broken internal links and point them to the best live page instead.
Find orphan pages
An orphan page is a page with no internal links pointing to it. It is like a shop with no street leading to it.
Look for important pages that no post links to, and add links from related posts.
Update old posts when you publish new ones
Each new post is a chance to make old posts better. Add a link from older related posts to the new one.
This keeps your whole blog connected and helps new posts get found faster.
Internal linking mistakes to avoid
- Using "click here" as anchor text everywhere
- Linking only to the home page and never to services or products
- Adding the same link many times on one page
- Leaving broken links after you change your site
- Never going back to old posts to link to new ones
Let your blog add internal links for you
Internal linking is simple, but it is easy to forget when you are busy. It also gets harder as your blog grows, because you need to remember every page you have.
AutomatedBlog adds internal links to every post it writes. It knows your service pages, your products and your earlier posts, and it links them with clear, natural anchor text. It also connects new posts to related older ones, so your blog grows as one connected site.
You can see how this fits with research, writing, images and scheduled publishing on the features page, or learn how the whole blog runs on its own with autoblogging software.
The short checklist
Link every post to a related service or product page. Link new posts from older ones. Use anchor text that describes the target page. Build small topic clusters. Fix broken links a few times a year.
Do these few things and your blog becomes easier to read, easier to find and better at turning readers into customers.
