7 Best Internal Linking Tools in 2026

Prices and features below come from each vendor's own pricing, feature and help pages, or its own WordPress.org or Shopify listing, checked on 12 October 2026. Prices are 'as of October 2026'. Rank Math showed prices in euros from our location, so they are given in euros.

Suggest or automate?

Suggestion tools show relevant pages while you write and leave the choice to the editor; they are safe but depend on someone using them. Automatic tools insert links across existing content based on keywords or entities; they fix large backlogs quickly but can add links an editor would not choose. A third group, crawlers, does not add links at all but shows where they are missing: orphan pages, pages buried deep in the site and pages with few internal links pointing at them.

At a glance (as of October 2026)

The tools, one by one

Link Whisper: WordPress, suggestions plus automation

Link Whisper is billed yearly: $97 for one site, $197 for 3 sites, $297 for 10 and $497 for 50, with AI credits included (2,000 to 10,000 by plan). Every plan lists auto-linking and a report to fix 404 errors and orphan pages. The main product is a WordPress plugin; Link Whisper also links to a Shopify app at $7 a month with a 7-day free trial, and a free plugin on WordPress.org lists 30,000+ active installations. There is a 14-day money-back guarantee on the first licence purchase only, not on renewals or credit purchases. Best for: WordPress content sites and the agencies that run them. Limit: the per-month totals on its pricing page do not match the yearly prices, so budget from the yearly figure.

InLinks: entity-based linking on any platform

InLinks builds links from the entities (topics) on each page and injects them with JavaScript, with no edits to templates or content, so it is not tied to WordPress. Freelancer starts at $49 a month for 100 pages; Agency starts at $196 a month for 430 pages; Enterprise covers 100,000 URLs and up on custom contracts. Usage runs on credits: adding a page costs 1 credit and an audit 5. Its site mentions ways to try InLinks free. Best for: sites on any CMS where editors cannot add links by hand at scale. Limit: links added by JavaScript depend on the script running, so check how they render for crawlers that do not execute JavaScript.

LinkStorm: automatic links with review

LinkStorm is priced by URLs: $30 a month for 1,000, $60 for 5,000, $120 for 20,000 and $200 for 50,000, each with unlimited projects and websites. It has WordPress, Shopify and Wix apps and says it works on any web platform, including JavaScript-heavy sites. Links can be added automatically and reviewed before they go live. Free trial without a card. Best for: agencies managing many sites on mixed platforms. Limit: the trial length and orphan-page reporting are not stated on its pages.

Yoast SEO Premium: suggestions as you write

Yoast SEO Premium is $118.80 a year for one site, with extra seats at $5 a month. It suggests relevant pages to link to while you write and includes an orphaned content workout that walks you through pages with no internal links. It does not add links automatically. Yoast refunds the full price within 30 days of an initial purchase. Best for: WordPress editorial teams that want linking built into writing. Limit: one subscription per site, and no automatic linking for an existing backlog.

Rank Math PRO: suggestions, orphan detection and AI linking

From our location Rank Math showed PRO at €7.99 a month billed annually (renewing at €8.99) for unlimited personal sites, Business at €24.99 for 100 client sites and Agency at €54.99 for 500 sites, with a 30-day money-back guarantee. Orphan-page detection is on PRO and up. Its AI Link Genius is built into PRO but its AI features need a separate Rank Math AI subscription; it suggests links and offers optional automated keyword linking. The free plugin shows link counts only. Best for: WordPress agencies managing many client sites cheaply. Limit: the promotional first-year price renews higher, and AI linking costs extra.

Surfer: linking inside the content editor

Surfer's one-click internal linking first appears on its Pro plan ($182 a month billed yearly); Discovery ($49) and Standard ($99) do not include it. It works inside Surfer's content editor while you optimise a page. Best for: teams already writing in Surfer. Limit: it is a content tool first, so it does not audit linking across the whole site.

A crawler, for finding the gaps

A desktop crawler such as Screaming Frog (free to 500 URLs, $279 a user a year for a licence) or Sitebulb (from $18 a month) records every internal link it follows. Pages that appear in your sitemap, analytics or logs but are never reached by the crawl are orphans. Screaming Frog's separate Log File Analyser lists finding uncrawled and orphan URLs among its uses. Best for: auditing linking on any platform before choosing a fix. Limit: it finds problems; you still add the links.

Internal links and AI answers

Internal links help assistants as well as search engines: they show which page is the main answer on a topic and help crawlers reach it. Fenn's readiness check includes internal links alongside AI-crawler access, llms.txt, structured data, answer-first content and freshness, and turns a failure into a fix with a ready prompt for a developer or AI coding tool. Fenn does not change your site or add links itself; one of the tools above does that. Plans start at $29 a month, set up after a demo.

How to choose

1. Platform first: WordPress has the most options; for other platforms look at InLinks or LinkStorm.
2. Backlog or new content: automatic tools for a large existing backlog, suggestion tools for ongoing writing.
3. Run a crawl before and after, and compare orphan pages and click depth for your most important pages.
4. For automatic tools, review a sample of added links before turning it on site-wide.

FAQ

What is the best internal linking tool for WordPress?

As of October 2026, Link Whisper is the most complete WordPress option, with suggestions, auto-linking and orphan reports from $97 a year. Yoast SEO Premium and Rank Math PRO suit teams that want suggestions inside the editor.

Can internal linking be automated?

Yes. Link Whisper and Rank Math (with its AI subscription) add links automatically on WordPress; InLinks and LinkStorm do it on any platform. Review a sample first, because automatic links can be off-topic.

How do I find orphan pages?

Compare a crawl of the site with a list of known URLs from your sitemap, analytics or logs; pages in the list that the crawl never reaches are orphans. Link Whisper, Yoast and Rank Math PRO also report them on WordPress.

Do internal links added with JavaScript count?

Only for crawlers that run JavaScript. Check how a page renders with JavaScript turned off to see what non-rendering crawlers receive.
