Link Whisper is a popular WordPress plugin for suggesting and managing internal links. It's genuinely good at what it does, but it has one obvious limitation: it's a WordPress plugin. If you're on Webflow, Next.js, a headless CMS, Shopify, or anything else, Link Whisper doesn't install. And even on WordPress, some teams want a different feature mix (deeper analytics, better orphan detection, a faster crawl, agency multi-site support).
This is a honest comparison of seven Link Whisper alternatives grouped by what they're actually best at, plus a quick framework for picking one.
When Link Whisper isn't the right tool
Three common reasons teams look for an alternative:
- Non-WordPress sites.Link Whisper's entire interface lives inside the WordPress admin. There isn't a hosted version. If your CMS isn't WordPress, you can't use it at all.
- Multiple sites or agency workflows.Link Whisper licenses are per-site, and the dashboard doesn't aggregate across properties. Agencies managing 10+ client sites usually want a hosted alternative with a single login.
- Audit-first workflow rather than suggestion-first. Link Whisper is great when you're actively writing and want suggestions in the editor. For periodic audits (find orphans, fix broken internal links, see overall link distribution), a crawler-based tool is usually faster.
Seven Link Whisper alternatives
1. InterlinkTool (cross-platform, audit-first)
Hosted, works on any stack (React, Next.js, Webflow, headless CMS, plain HTML). Crawl-based: it audits your existing internal link structure, surfaces orphan pages, broken internal links, inbound and outbound distribution per URL, and prioritizes a fix list by SEO impact. No WordPress plugin required.
Best for: Non-WordPress sites, agencies managing multiple properties, teams that want periodic audits rather than in-editor suggestions. Free to try, no credit card required.
2. Yoast Internal Linking Suggestions
Yoast's premium plugin includes internal linking suggestions in the WordPress editor. Less aggressive than Link Whisper's suggestion engine, but tightly integrated with the rest of the Yoast SEO workflow. Cheaper than Link Whisper if you already pay for Yoast Premium.
Best for: WordPress sites already on Yoast Premium who want one tool for SEO and linking.
3. Rank Math
Rank Math's Pro tier has Link Suggestions and Link Counter modules. Functionally similar to Link Whisper's suggestions, with the same WordPress-only constraint. Pricing tends to come in cheaper than Link Whisper, especially for multiple sites.
Best for: WordPress sites already using Rank Math for SEO.
4. InLinks
Entity-based internal linking. Instead of matching keywords, InLinks classifies the entities (concepts, brands, people) mentioned on each page and links them semantically. The output tends to be more contextually relevant than keyword-match linking, at the cost of some setup complexity.
Best for: Content-heavy sites where semantic relevance matters more than raw link count. Works on most modern stacks via a script tag.
5. LinkStorm
A hosted internal linking tool that crawls any site and suggests links between existing pages. Includes orphan page detection and a link-graph visualization. UI is clean. Works outside WordPress.
Best for: Teams that want both an audit view and on-demand suggestions, on any stack.
6. Screaming Frog SEO Spider
Not an internal linking tool exactly, but it's the industry-standard crawler and gives you all the raw data: every internal link, inbound and outbound counts per URL, orphan pages, broken links. The trade-off is a desktop app with a UI from another era; you're responsible for the analysis workflow on top of the raw data.
Best for:Technical SEOs who want maximum control and don't mind the desktop install.
7. Sitebulb
A more modern alternative to Screaming Frog. Same crawler-based approach but with built-in visualizations and a clearer audit-style interface. Strong on internal linking analysis specifically, including link equity flow.
Best for: Agencies and consultants doing deep audits across multiple client sites.

Which one to pick
Four rough decision rules:
- You're on WordPress and want suggestions while you write.If you don't already pay for Yoast Premium or Rank Math, stick with Link Whisper. If you do pay for one of those, use that built-in feature first; you may not need a separate tool.
- You're not on WordPress. InterlinkTool, InLinks, LinkStorm, Screaming Frog, or Sitebulb. The first three are simpler; the last two are deeper.
- You run multiple sites or you're an agency. A hosted tool wins over per-site plugins. InterlinkTool, LinkStorm, or Sitebulb. Per-site plugins (Link Whisper, Yoast, Rank Math) get expensive and unwieldy past 5 to 10 properties.
- You want maximum technical control.Screaming Frog is still the answer. It gives you the raw data and you're free to do whatever analysis on top.
Audit any site, no plugin required
If you're on a non-WordPress stack and want a focused internal linking audit without installing anything, InterlinkTool crawls your site, surfaces orphans and broken links, prioritizes fixes by SEO impact, and supports multi-site agency workflows. Free to try, no credit card required.
Frequently asked questions
Does Link Whisper work outside of WordPress?
No. Link Whisper is a WordPress plugin only. It doesn't ship a hosted version or support other CMSes. If you're on Webflow, Next.js, Shopify, a headless CMS, or anything else, you need a different tool.
What's the best free Link Whisper alternative?
InterlinkTool has a free tier that works on any stack. Screaming Frog SEO Spider is free up to 500 URLs and works on any site, though the interface is dated. For WordPress sites specifically, Yoast SEO's free version includes basic internal linking analysis without the suggestions feature.
Is Yoast a Link Whisper alternative?
Yoast Premium includes internal linking suggestions and is a reasonable substitute if you're already using Yoast for SEO. The suggestions are less aggressive than Link Whisper's, but the integration with the rest of the Yoast workflow is tighter.
How much does Link Whisper cost?
Link Whisper's pricing starts around $77 per year for a single site and scales up for multi-site licenses. Pricing changes periodically, so check their site for current numbers. Most hosted alternatives are billed monthly instead of annually.
Which internal linking tool is best for agencies?
Hosted tools win over per-site plugins for agencies because you get one dashboard across all client sites. InterlinkTool, LinkStorm, and Sitebulb all support multi-site workflows. Per-site plugins like Link Whisper, Yoast Premium, and Rank Math become expensive and hard to manage past 5 to 10 client properties.
