Buyer's guide
Most comparisons in this category line up eight plugins in a table of ticks and let you guess. The useful move is to notice they are not the same kind of product. Once you separate where the thinking happens from how you are billed for it, the shortlist gets much shorter.
| Kind | How it works | Who |
|---|---|---|
| Cloud platform | Your content is analysed on their servers; you are billed per link inserted | LinkBoss |
| Self-contained plugin | Everything runs inside WordPress on a flat licence | JnK Linkweave, Internal Link Juicer, Link Whisper, Linkilo |
| SEO suite with a linking module | Linking bundled into a product you already pay for | Rank Math PRO |
These are not interchangeable. A cloud platform can rewrite sentences and build silo structures at a scale no in-WordPress plugin attempts, and charges accordingly. A suite module costs you nothing extra but goes only as deep as a suite module needs to. A dedicated plugin sits between them.
This is the axis that decides the money, and it is the one most tables bury. A credit allowance costs little when you start and then quietly shapes how you work — you begin deciding whether a link is worth a credit, which is not a question anyone should be asking about their own site.
| Tool | Billing shape | Entry price | Free tier |
|---|---|---|---|
| JnK Linkweave | Flat, unmetered | $59/yr · 1 site | Yes, unlimited sites |
| Internal Link Juicer | Flat, unmetered | $69.99/yr · 1 site | Yes, 1 site |
| Link Whisper | Flat licence, AI credits per tier | $97/yr · 1 site | No |
| Linkilo | Flat, unmetered | $149/yr list, $59 launch | No |
| LinkBoss | Credits, expire monthly or yearly | $132/yr list, $99 sale | 50 credits |
| Rank Math PRO | Bundled in the suite | €7.99/mo billed annually | Free SEO plugin, no Link Genius |
Every tool here will find you linking opportunities. That is the easy half. The half that consumes actual time on a site older than a year is maintenance: URLs change and links rot, posts get deleted, some links get clicked and most do not, and pages slip into being orphans without anyone noticing.
It is worth checking which of these a tool covers before you buy, because it is where they differ most and where the marketing pages are quietest. Linkweave Pro carries bulk URL changing with one-click rollback, one-click broken-link repair, internal link click analytics, Search Console CSV import for targeting posts that are close to ranking, topic cluster mapping, and cross-site linking between sites you own. The free build already reports orphan pages and broken links read-only, so you can see the size of the problem before paying anybody.
If you already pay for Rank Math PRO, AI Link Genius is included and does bulk linking with rollback. Use it first and only come back if it falls short. If you need thousands of links inserted across many sites, or sentences rewritten so an anchor reads naturally, LinkBoss operates at a scale we do not attempt. If you want one purchase to also cover redirects, crawl logs and cannibalisation, Linkilo is a genuinely good consolidation play. And if your site has a clear keyword-to-page map you already maintain, Internal Link Juicer executes that model well.
And the thing that counts against us right now. Linkweave's free build is not currently installable from the WordPress plugin directory — the listing is closed while an account matter is resolved and we do not control that timeline. The free version is a direct download from us in the meantime. Every other tool on this page installs normally. If a one-click install matters to you, that is a fair reason to wait.
Found something wrong on this page? Every vendor here changes pricing without notice, and at least one competitor's comparison page currently quotes a rival's price that is two years out of date. We would rather be corrected than join them — [email protected].
It depends what you disliked about it. If the AI credit allowance is the issue, JnK Linkweave and Internal Link Juicer are both unmetered flat licences. If you want more scale than any plugin offers, LinkBoss is a cloud platform. If you want to consolidate several plugins into one, Linkilo covers redirects and crawl logs as well as linking. And if you already pay for Rank Math PRO, AI Link Genius is included at no extra cost.
Yes. JnK Linkweave has a free tier with no site limit that includes editor link suggestions, unlimited auto-linking rules, inbound link counts and read-only orphan-page and broken-link reports. Internal Link Juicer has a free version for one site covering posts and pages. LinkBoss gives 50 free credits on signup. Link Whisper and Linkilo have no free version.
Some do. LinkBoss meters interlink insertion in credits that expire monthly on its monthly plans and yearly on its annual plans. Link Whisper includes a fixed AI credit allowance with each tier and sells top-up credit plans. JnK Linkweave, Internal Link Juicer and Linkilo charge a flat licence with no per-link cost.
Rank Math PRO now includes AI Link Genius, which finds and inserts internal links in bulk with one-click rollback, so if you already pay for PRO you should try that first. A dedicated plugin adds what surrounds that: click analytics on internal links, Search Console targeting, cross-site linking and topic cluster mapping. Linkweave runs alongside any SEO plugin rather than replacing one.
It varies and it is worth checking. Cloud platforms analyse your content on their servers by design. JnK Linkweave scores relevance with BM25 and TF-IDF in PHP on your own server, so nothing is sent anywhere to produce a suggestion, unless you opt into the bring-your-own-key LLM re-ranking mode in Pro and supply your own provider key.
For a single site, entry pricing across the category currently runs from about $59 to $97 a year, with JnK Linkweave at $59, Internal Link Juicer at $69.99, Link Whisper at $97 and Linkilo at $59 on launch pricing against a $149 list price. The differences get much larger at higher site counts: unlimited sites ranges from $299 a year to $1,299.
