Internal links are the cheapest SEO win you have. They help Google find new posts, show which pages matter most, and keep readers moving through your site. The problem is doing it consistently once you have 50, 100 or 500 posts. Nobody remembers what they wrote two years ago.
That is where internal linking plugins help. They suggest relevant links as you write, find orphan posts, and, in some cases, add links automatically. This WordPress internal linking plugins guide compares the best ones and explains how to use them without turning your posts into link soup.
Short answer: Link Whisper is the best dedicated internal linking plugin, with the most useful suggestions and orphan-post reports. If you already use Rank Math or Yoast SEO Premium, try their built-in link suggestions first. For a budget pick with solid analytics, Link Manager (formerly Interlinks Manager) is worth a look.
Why Internal Linking Matters
- Discovery. Google finds new pages by following links. A post with no internal links (an orphan) can take weeks to be crawled. I cover this in how to index your website quickly.
- Relevance. Anchor text tells Google what the linked page is about.
- Priority. Pages with more internal links pointing at them look more important.
- Engagement. Readers who click through to a second post are more likely to subscribe or buy.

How I Picked These
I judged each plugin on the quality of its suggestions (are they actually relevant?), how easy it is to add a link from the editor, reporting (orphans, link counts, broken links), whether auto-linking can be controlled, and performance on larger sites.
6 Best WordPress Internal Linking Plugins
Link Whisper
Best for: blogs with 50+ posts. Price: free version on WordPress.org, Premium licensed by number of sites. Learning curve: low
Link Whisper reads your content and suggests internal links right under the editor, with the anchor text already highlighted.
You tick the ones you like and click insert. It also suggests inbound links, meaning older posts that should link to the one you are writing, which is the part most tools skip.
The reports show orphan posts, link counts per page and broken links. Suggestions are not always perfect, so review each one. On very large sites, the initial scan takes a while.
Best features: inbound link suggestions, orphan post report, auto-linking by keyword, optional AI suggestions.
Pros
- Best suggestions and reports
- Inbound link suggestions
- Saves hours on big blogs
Cons
- Premium is paid yearly
- Suggestions need a human check
Rank Math (built-in link suggestions)
Best for: Rank Math users on a budget. Price: free, Pro available. Learning curve: low
If you already use Rank Math, you have a link suggestions box in the editor for free. It lists related posts based on your focus keyword, and you can copy the link or insert it.
It is basic: no inbound suggestions and no orphan report. For small blogs, it is often enough.
Best features: free link suggestions, pillar content marking.
Pros
- Free
- No extra plugin
Cons
- Basic suggestions
- No orphan report
Yoast SEO Premium
Best for: Yoast users. Price: part of Yoast SEO Premium. Learning curve: low
Yoast Premium includes internal linking suggestions in the sidebar and an orphaned content filter in the posts list, plus a text link counter. It works well if you already pay for Yoast Premium.
It is not worth buying just for linking, because the suggestions are less detailed than Link Whisper’s.
Best features: orphaned content filter, cornerstone content workflow, link counter.
Pros
- Built into your SEO plugin
- Orphan detection
Cons
- Premium only
- Simpler suggestions
AIOSEO Link Assistant
Best for: All in One SEO users. Price: included in AIOSEO Pro-level plans. Learning curve: low
Link Assistant scans your site and shows inbound, outbound and internal link counts for every post, highlights orphans, and suggests links you can add with one click from its dashboard.
It is well designed. It only makes sense if you use AIOSEO as your SEO plugin, and it sits in the higher plans.
Best features: link report dashboard, one-click suggestions, orphan detection.
Pros
- Clear reports
Cons
- Requires AIOSEO higher plans
Link Manager (formerly Interlinks Manager)
Best for: data-minded bloggers. Price: $59/yr (1 site), $99/yr (5 sites), $149/yr (25 sites). Learning curve: medium
DAEXT’s Link Manager focuses on analysis: it calculates link equity per URL, counts manual and automatic links, checks for broken links and tracks clicks on internal links.
It also offers suggestions in the editor and keyword-based auto-linking. The plugin keeps working if your license expires; you just lose updates. The interface is more technical than Link Whisper.
Best features: link equity analysis, click tracking, broken link checks, CSV export.
Pros
- Affordable
- Detailed analytics
Cons
- More technical
Internal Link Juicer
Best for: automatic keyword-based linking. Price: free, Pro available. Learning curve: low
Internal Link Juicer works differently. You assign keywords to each post, and the plugin automatically links those keywords wherever they appear across your site, with limits you set.
It is fast to set up, and the free version is useful. The risk is over-linking with repetitive exact-match anchors, so keep the limits low.
Best features: automatic linking, per-post keyword settings, link limits.
Pros
- Set and forget
- Useful free version
Cons
- Easy to overdo
- No suggestions for context
A Simple Internal Linking Strategy
A plugin speeds up the work, but you still need a plan. This is the one I use on WPSBlog.
- Pick your pillar pages. These are your broad guides, like the WordPress SEO guide or how to improve WordPress speed.
- Link supporting posts to the pillar. Every caching, image or theme post links back to the speed guide, for example.
- Link the pillar out to supporting posts. The speed guide links to the caching plugins and image optimization plugins posts.
- Link sideways between related posts. Two posts on themes should mention each other where it is useful.
- Link every new post from 2 or 3 older posts that already get traffic.
- Run an orphan check once a month and fix any post with zero inbound links.
Important note: Use descriptive anchor text that reads naturally (“my guide to caching plugins”), not the same exact keyword every time. Three to eight contextual internal links in a 2,000-word post is plenty. More than that and readers stop clicking.
Common Internal Linking Mistakes
- Linking only from a “related posts” widget instead of inside the content.
- Using “click here” as anchor text.
- Adding nofollow to internal links. There is no reason to do this.
- Linking to URLs that redirect. Update old links after you change a slug.
- Auto-linking the same keyword on every page.
FAQs Related to Best WordPress Internal Linking Plugins
Is Link Whisper worth it?
For blogs with more than 50 posts, yes. It saves time and finds links you would miss. For a new blog with 10 posts, link manually.
Can internal linking plugins hurt SEO?
Only if you let auto-linking run wild with repetitive exact-match anchors. Review suggestions and keep links natural.
How many internal links should a post have?
There is no fixed number. Aim for links wherever they genuinely help the reader, usually 3 to 10 in a long post.
What is an orphan page?
A page with no internal links pointing to it. Search engines and readers struggle to find it.
Do I need a plugin for internal linking?
No. You can search your own site on Google with the site:yourdomain.com keyword to find related posts. A plugin just makes it faster. Other must-haves are in my must-have plugins list.
Final Verdict
That’s all about the list of Best WordPress Internal Linking Plugins.
If internal linking is a chore you keep skipping, Link Whisper is the plugin that makes it a habit.
If you want to spend nothing, use Rank Math’s free suggestions and a monthly manual orphan check.
Either way, the strategy matters more than the tool: pillars, supporting posts, and a link to every new post from something that already ranks.
