See the internal linking tool in action

Watch Contentpen map a sitemap, write an article with internal and external links already in place, and flag every link's health before publishing.

1. Connect your sitemap

Add your sitemap or RSS feed, filter out pages you don’t want linked, and use ‘Test Sitemap URLs’ to preview every linkable page.

2. Set your link rules once

Turn on external links, paste lists of included and excluded domains, and pick target and rel defaults. Save everything to a content preset so every future article follows the same rules.

3. Generate, review, and publish

Links are placed while the article is written, with no separate linking step. Review each one in the Links panel, adjust anything you like, and publish with every link working.

Your sitemap becomes your link map

Contentpen crawls your sitemaps into its knowledge base and learns how your pages relate by topic. New articles link back to pillar pages, supporting posts, feature pages, and case studies that deserve the traffic, so no page is left orphaned.

External sources that back up every claim

External sources that back up every claim

Contentpen searches the web for relevant, high-quality pages in your niche and language, then links the exact study or article instead of a homepage. It never links to competitor pages, and your included and excluded domain lists always win.

Anchors that read naturally, never stuffed

Anchors that read naturally, never stuffed

Every link uses a short, descriptive anchor of 2 to 6 words that matches the page it points to. Anchors vary across the article, so readers know where each click leads and search engines never see repeated, over-optimized phrases.

One rule set for every AI-generated link

Set link behavior once: same tab or new, follow or nofollow, plus noopener protection. Every writer inherits the same defaults.

Find the right link for any sentence

Find the right link for any sentence

Highlight any phrase, and Contentpen suggests matching pages from your sitemap or relevant web sources. Ask AI can also add internal links on request, using only real pages on your site.

Catch broken links before readers do

The Links panel lists every internal and external link in the article with a live, redirect, or dead status. Locate any link in the text, copy it, open it, and confirm its tab and rel settings without leaving the editor.

Catch broken links before readers do

How an unlinked blog can affect your SEO and GEO

Every article published without a linking plan quietly weakens the rest of your site.

Pages search engines barely find

Posts with no internal links pointing to them are harder for crawlers to discover and slower to rank. The more you publish, the more orphaned pages pile up out of sight.

Pillar pages without the support they need

Topic clusters only build authority when supporting articles link back to the pillar. Skipping those links leaves your most important pages competing alone.

Weaker signals for AI answers

Well-linked content and cited sources show depth and trust, which matter for AI visibility. An SEO- and GEO-optimized article loses that edge when its claims and related pages go unlinked.

Senior hours spent cross-referencing URLs

Checking sitemaps, choosing anchors, and testing links by hand takes hours per article. Across an enterprise or agency calendar, that time comes straight out of strategy.

Give every page the links it deserves

Connect your sitemap once, and every SEO and GEO-optimized article ships with relevant internal links, trusted sources, and healthy anchors.

Frequently asked questions

Answers on how Contentpen's internal linking tool finds, places, and checks links across your blog.

An internal linking tool finds related pages on your site and adds links between them, so readers keep exploring and search engines crawl and index more of your content. Contentpen goes further by placing credible external sources while each article is written, then checking every link's health before publishing.
Contentpen crawls your sitemap and reads each page for meaning, not just matching keywords. When it writes an article, it links to the pages that best answer the reader's next question, using short, descriptive anchors of 2 to 6 words that fit the sentence naturally.
There is no fixed number that Google requires. Add links wherever they help the reader take the next step, and make sure every important page is reachable from related content. Contentpen places links where they add value and varies anchors, so articles stay useful without stuffing.
Yes, when they point to relevant, trustworthy sources. Well-chosen external links let readers verify claims and show the research behind your content. Contentpen links specific studies and articles in your language, skips competitor pages, and follows your included and excluded domain lists.
Yes. Paste lists of included domains to prefer and excluded domains to block, or turn automatic external links off entirely. You also choose whether external links open in a new tab and use follow, nofollow, or sponsored, with noopener noreferrer added for security.
Yes. Every link stays editable in the content editor before you publish. Change the anchor text, swap the destination, switch it to open in a new tab, or remove it entirely, and use Locate in article to jump straight to any link from the Links panel.
Yes, inside every article. The Links panel shows each internal and external link with a live, redirect, or dead status, so you can fix broken or redirected links before readers ever click them. It checks the links in your article rather than crawling your whole site.
Yes. Paste the post's URL into Content Refresh, and Contentpen keeps the links already on the page while adding new internal links from your sitemap where they fit. The refreshed post then updates in place on your CMS, with no duplicate URL.
On their own, they don't know which pages exist on your site. Connect them to the Contentpen MCP server, and they can write SEO- and GEO-optimized articles that follow your saved presets, including your sitemap and linking rules, then publish them to your CMS from a chat.
It links only where a page or source adds value to the sentence, keeps anchors short and varied, and avoids repeating the same external domain. Your SEO score's linking checks then confirm the balance of internal and external links before you publish.

What is internal linking?

Internal linking is the practice of connecting one page on your website to another through links in your content. Search engines follow these paths to discover pages, understand how they relate, and judge which ones carry the most authority.

For readers, a well-placed internal link answers the next question before they ask it. That keeps them on your site longer and lowers bounce rates, which supports the organic traffic you want to grow.

What is the difference between internal and external links?

Internal links point to other pages on your own site, such as related guides, feature pages, or case studies. External links, also called outbound links, point to pages on other sites, such as industry studies or benchmarks that support your claims. Links other sites point to you are part of off-page SEO.

How to build internal links for SEO in 5 steps

  1. List the pages you want to rank, such as pillar pages, feature pages, and high-value guides.
  2. Group related articles into topic clusters around each pillar.
  3. Link every supporting article to its pillar and to closely related posts.
  4. Use short, descriptive anchors that tell readers where the link leads.
  5. Check links regularly and fix redirects or broken URLs.

Contentpen handles steps 3 to 5 automatically once your sitemap is connected. See the full walkthrough in our guide on how to automate internal and external linking.
