Would you like your blog to generate more traffic from search engines? And would you like those new visitors to continue reading other content on your site instead of leaving?
A low-hanging fruit solution exists: Link more to your older content.
What are internal links?
Internal linking (or interlinking) involves adding links to other pages on your website. They can help:
- Direct clicks to older content
- Engage readers to continue their journey through your site
- Improve your site’s search crawlability, helping search bots find more of your pages.
In fact, internal links are fundamental to your content findability and for that reason, it’s the very first Google’s webmaster guideline: “Ensure that all pages on the site can be reached by a link from another findable page.”
Internal links also help Google understand your site’s structure and determine which are the more important pages based on the quantity of internally linked content.
How to add internal links
Internal links can be placed in:
- Main navigation
- Unique main content (also known as contextual links)
Contextual links can be inserted directly into the content or added as standalone boxes to promote further reading. All these links must be directly relevant to the content on the page.
Though little evidence confirms this educated guess, contextual links may carry the biggest SEO value because they are editorially relevant and hardly ever automated.
Always think about striking a balance between internal linking and general readability. Historically, Google recommends using descriptive anchor text when adding internal links. Consider anchoring links through the keywords used in the content. When appropriate, use a call to action for the internal link, such as “Read more here about KEYWORD” or “Here’s more detailed information on KEYWORD.”
How to identify link-worthy content
Much of your interlinking strategy will rely on your editorial direction and calendars. Likely, your familiarity with the content will create some obvious choices. Here are a few general suggestions to help identify the more valuable content to link to:
Keep an eye on your high-ranking content
Link to content that’s already successful. Google’s Search Console is a great place to find those pages. Go to the Performance section and click through to the Pages tab:

How to determine the number of internal links
There’s no magic number: Think about your readers and what they may be interested in reading. When it comes to SEO, there’s no good answer as well. Though its advice has evolved over the year, it more recently has said there’s no such thing as an internal-linking over-optimization penalty, but cautioned that sites shouldn’t link every page to every other page on the site.
It seems content creators have some freedom on the number of internal links, but the key is that they must be natural and useful to the reader.
