The best internal linking plugins for WordPress, compared honestly — prices checked in October 2026.

Most “best internal linking plugin” lists are written by somebody selling one of the plugins. This one is too: we make Silotree, which is in it. So rather than ask you to trust a ranking, this guide gives you what you need to check it yourself — what each tool actually does, where the links it creates are stored, what it costs on which plan, and a link to the page each fact came from. Prices checked 11 October 2026.

If you are still deciding what your links should do before choosing a tool, start with our internal linking strategy guide. A tool speeds up a plan; it does not supply one.

How this roundup was checked

For each tool we read the vendor’s own pricing and feature pages and, where a free version exists, its WordPress.org listing, which shows active installs and when it was last updated. Every price below carries its plan and billing period. Three caveats:

• Some prices showed in euros. Rank Math and All in One SEO showed us prices in euros, excluding VAT, because of where we were browsing from. We quote what the page showed rather than converting.
• Introductory prices renew higher. Rank Math and All in One SEO both state a higher renewal price than the first-year price. Both figures are given.
• One vendor contradicted itself. Linkbot showed different prices on two of its own pages. Both are given, with links.

We did not install every paid tier. Feature claims describe what each vendor says its product does, with a link, not a lab test. Where we could not confirm something — what happens to LinkStorm’s links after you cancel, for example — we say so.

We also read the lists that currently rank for this search. The two we read in full, from WPBeginner and NexterWP, cover features (WPBeginner adds prices), but neither explains where a tool’s links are stored, what happens to them when you uninstall, or whether the tool can write into page-builder layouts. The WPBeginner list ranks All in One SEO first and discloses affiliate commissions; the site is run by Awesome Motive, whose products include All in One SEO. That is not a reason to dismiss it — it is a reason to check any list, this one included, against the vendors’ own pages.

At a glance: what each tool does and costs

“Entry price” is the cheapest paid plan that includes the tool’s internal linking features, on the billing period stated. Install counts are WordPress.org’s own rounded figures.

Four kinds of tool, and where their links live

The tools above look alike in a feature grid and behave very differently on a real site. They fall into four kinds:

1. Keyword auto-linkers. You map a phrase to a page; the tool links that phrase wherever it appears. Fast to set up and hands-off afterwards, but it cannot tell whether this particular paragraph is the right place for the link.
2. Suggestion tools. The tool proposes a target page (and often the words to link) and you accept or skip each one. Slower, much more control.
3. AI linkers. Suggestions chosen by meaning rather than shared keywords. Some go further and rephrase your sentence or write a new one to carry the link.
4. Audit-only tools. They tell you which pages are orphaned, which links are broken and how deep pages sit. They change nothing.

The second question matters more than most reviews admit: where does the link end up? A link written into the post is part of your content from then on. A link added as the page is built, or injected by a script in the visitor’s browser, exists only while the tool is running.

Script-injected links do work for Google: its documentation on crawlable links says links inserted into a page with JavaScript can be crawled, as long as they are ordinary <a href> elements. The trade-offs are elsewhere: the links depend on a subscription, and you are relying on every crawler you care about to run JavaScript as Google does.

Dedicated linking plugins

Link Whisper

What it does. Suggests links as you write and, more usefully, adds inbound links to an existing post from older posts in bulk. Paid plans add auto-link rules, a URL changer, broken-link checks, Search Console data and AI-powered suggestions, with an allowance of AI credits per plan. It reports orphan pages and links in and out of every post.

Price. On its pricing page: Starter $97 a year for 1 site, Growth $197 a year for 3 sites, Pro $297 a year for 10 sites, Agency $497 a year for 50 sites. Starter is also offered at $29 billed monthly. (The page builds its price table in the browser; we read the plan figures from the page itself.) The free version on WordPress.org has 30,000+ active installs, was last updated in August 2026, and includes editor suggestions and a link report.

Strengths. The most hands-on control of any tool here: you see every suggestion in context and can work outward from the page you want to promote. Links are written into the post, and the vendor’s knowledge base confirms they stay if you remove the plugin.

Limitations. Annual pricing is the default; the free version is a taster rather than a working tool on a large archive. As with any suggestion tool, the work scales with the number of posts you review.

Best for: people who want to approve or edit every link by hand, especially across several sites, where the 50-site plan is good value. Our Link Whisper comparison lists the cases where it beats Silotree.

Internal Link Juicer

What it does. Pure keyword auto-linking. You give each post the keywords it should be linked for, and the plugin links those words across the site. Its WordPress.org page is explicit that it builds links from its own index as the page is output and “the content itself is not manipulated by the plugin.” Pro adds category and tag targets, links from custom fields with ACF and page-builder compatibility, keyword import from Yoast and Rank Math, and a silo option that limits links to posts in the same category.

Price. Free for 1 site, with 90,000+ active installs (version 2.26.0, last modified August 2026). Pro, on its own site: $69.99 a year for 1 site, $149.99 a year for 5, $189.99 a year for 10, and $1,299 a year for unlimited sites.

Strengths. Configure once and walk away. Because nothing is written into your posts, removing it removes every link cleanly — the reverse of most tools here.

Limitations. The same reason cuts the other way: deactivate it and every link it made disappears at once. Keyword rules also tend to put the same anchor text on the same target from hundreds of posts. Zyppy’s study of 23 million internal links found pages with more varied internal anchor text correlated with more Google traffic — a correlation, as its author stresses, not proof, but a reason to keep auto-link limits tight.

Best for: a single site on a budget that wants simple keyword linking without touching post content. The free version is genuinely the better choice there. The Internal Link Juicer comparison covers what happens to its links if you switch.

Link Manager by Daext (formerly Interlinks Manager)

Is Interlinks Manager still sold? Not as a new product. Its WordPress.org listing says it has been superseded by Link Manager and will get compatibility and security updates until 8 July 2027, after which it will be removed from the directory. The old address now redirects to Link Manager.

What it does. According to its product page, the free Lite version includes keyword auto-links with per-post and per-target limits, a test mode, and per-post link and link equity statistics. Pro adds editor suggestions (scored by title overlap, categories and tags), broken-link detection, click tracking and CSV export.

Price. Pro: $59 a year for 1 site, $99 a year for 5, $149 a year for 25.

Best for: people who want link statistics and keyword auto-links in one inexpensive plugin, and agencies where the 25-site price is hard to beat. Suggestions are keyword- and taxonomy-based, not semantic.

AI and SaaS linkers

LinkBoss

What it does. A web app with a WordPress plugin that syncs your content. Its home page describes a “pipeline” that first tries to link an existing sentence, then rephrases one, then adds a new sentence to carry the link. It also builds silos, finds orphans and reads Search Console. The WordPress.org plugin (2,000+ installs) says links are real HTML written into your content, so they stay if the plugin goes.

Price. Credit-based: one credit per link on an existing sentence, two per link from the sentence generator. A free account gets 50 credits. Monthly: Launch $11 (200 credits, 1 site), Scale $37 (1,000 credits, 3 sites), Agency $99 (2,500, 10 sites), Dominator $549 (15,000, 50 sites). Yearly, Launch is $99 for 2,400 credits. There are also unlimited-credit plans: Solo Boss at $87 a year for 1 site of up to 1,000 pages, and Multi Boss at $197 a year for 3 sites. All are listed on the home page with a 14-day money-back guarantee.

Strengths. It can place a link where none of your existing words fit, which no sentence-only tool can. Built for volume.

Limitations. Rephrased and added sentences are AI-written text in your posts. On a site where every sentence has a named author, or where you edit somebody else’s writing, that needs a policy. Credits make costs harder to predict on a big backlog.

Best for: SEO teams running large or programmatic sites who are comfortable with AI-written bridging text. The LinkBoss side-by-side says plainly where it is more powerful.

LinkStorm

What it does. A web app that crawls the site, audits links and suggests new ones using AI. When you accept a suggestion, its help centre says a JavaScript snippet inserts it into the page; an Auto-Accept setting inserts suggestions without review, and automated insertion needs an active subscription. It works on any platform, not only WordPress.

Price. On its pricing page: Small $30 a month (1,000 URLs), Medium $60 (5,000), Large $120 (20,000), XL $200 (50,000), each with unlimited projects and websites and a free trial without a card.

Limitations. Links live in the snippet, not your posts. We could not find a statement of what happens to inserted links when a subscription ends; ask before you rely on it. Its WordPress plugin, which only installs the snippet, shows 90+ installs and a warning that it has not been tested with the last three major WordPress releases. You can add the snippet by hand instead.

Best for: people managing sites on several platforms, where one dashboard and unlimited websites matter more than having the links stored in each CMS. Our LinkStorm comparison goes through the trade-off in detail.

Linkbot

What it does. Automated linking added by “two lines of copy-and-paste code”, according to its home page, with each link approved or rejected before it goes live. It also generates short call-to-action snippets that link to conversion pages.

Price. The home page lists a free Starter report (1 site, up to 1,000 URLs, no automated linking), Pro at $19 a month (5 sites, 1,000 URLs each), Business $49 (10 sites, 10,000 URLs each) and Agency $199 (50 sites), with a 14-day trial and two months free on annual billing. Its AI linking page showed different plans on the same day: Starter $49, Professional $99 and Business $299 a month. Confirm with Linkbot before buying.

Best for: non-WordPress or mixed estates where a script is the only practical way to add links. On WordPress, the same rented-links caveat as LinkStorm applies; the Linkbot and Silotree comparison explains what that means if you cancel.

Linking inside the big SEO plugins

If you already run an SEO plugin, check what it includes before buying anything. For linking the post in front of you, it may be enough.

Rank Math (link suggestions, Content AI and AI Link Genius)

What it does. The free plugin lists internal link suggestions among its features on WordPress.org (4+ million installs). Rank Math’s knowledge base explains that suggestions come only from posts you have marked as pillar content, matched by title or focus keyword, and you can insert one into your content with a click. No pillar posts, no suggestions. AI Link Genius is the newer, larger tool: link audits, an orphan-posts filter, keyword auto-linking with AI-generated variations, bulk link updates with preview and rollback, and AI suggestions in the editor. Its FAQ says the non-AI parts are included in PRO while the AI features need a separate Rank Math AI subscription, which also includes its AI content features.

Price (shown to us in euros, ex VAT, billed annually): on the Rank Math pricing page, PRO is €7.99 a month for unlimited personal sites, renewing at €8.99; Business is €24.99 a month for 100 client sites, renewing at €27.99. On the Rank Math AI pricing page, Starter is €5.99 a month, renewing at €6.99, with Creator and Expert above it.

Best for: sites already on Rank Math. The free pillar-based suggestions are a fine start for a small blog. The Rank Math comparison covers when it is all you need.

Yoast SEO Premium

What it does. The Premium product page describes internal linking suggestions as you write and an orphaned content workout. Its help page confirms the orphaned content filter on the posts list is a Premium feature.

Price. $118.80 a year, excluding VAT, for one site; one subscription covers one site or domain.

Best for: a single site already on Yoast that wants help linking new posts as they are written; it is built around the post in the editor rather than bulk changes to old posts. See the Yoast and Silotree comparison for the difference in approach.

All in One SEO: Link Assistant

What it does. Its feature page describes AI-powered link suggestions, one-click insertion, an anchor text generator and reports on how links are distributed. It is an add-on for the Pro and Elite plans.

Price (shown to us in euros, billed yearly): on the AIOSEO pricing page, Pro is €199.50 for the first year for 10 sites (listed as normally €399), and Elite €299.50 for 100 sites (normally €599). The page’s own FAQ says renewal is higher than the introductory rate.

Best for: sites already paying for AIOSEO Pro. Buying Pro just for Link Assistant costs more than the dedicated plugins, as the AIOSEO Link Assistant comparison shows.

Two more tools come up often enough to have their own pages: the entity-based InLinks comparison and the Linkilo comparison. Every option is side by side on the comparison overview.

Audit only: Screaming Frog

What it does. Screaming Frog’s SEO Spider is a desktop crawler. It finds broken links, redirects, depth, canonicals and every link on every page. It adds no links. Its orphan pages tutorial shows how to find pages that appear in your sitemap, Analytics or Search Console but are not linked — the Analytics and Search Console integrations need a licence.

Price. Free up to 500 URLs per crawl. A licence is $279 per licence per year for 1–4 licences, falling to $235 each for 20 or more, on its pricing page.

Best for: full technical audits. For that job, nothing else in this list replaces it, and the Screaming Frog comparison says so. It pairs naturally with one of the tools above: Screaming Frog finds the problems, the linking tool fixes them. Our internal link audit checklist works with either.

Silotree, including where it falls short

What it does. A WordPress plugin and web app built around contextual links. Every suggestion is a phrase from a sentence you already wrote in a related post; you approve or skip each one. You clear the backlog first, then get up to five new suggestions a week by email. Suggestions also show in a live editor sidebar (block editor) and a Classic Editor box, on every plan, with no account needed. It finds orphans, dead ends, broken links and links through redirects, fixes the last two in one click on every plan, and detects competing posts from Search Console queries. Keyword auto-link rules exist but never run on their own: you preview, then apply them as a batch you can undo.

Where links live. In the post. It saves a WordPress revision before writing, skips posts open in the editor, reads the post back afterwards and restores it on a mismatch. Any batch can be undone on every plan, and undo removes only Silotree’s links.

Price. Free (1 site, 500 pages per scan), Solo $19 a month (1 site, 5,000 pages), Studio $49 a month (5 sites, 20,000), Agency $129 a month (25 sites, 50,000). Yearly is ten times monthly. The first 10 links are written free on every plan, and there is a 30-day money-back guarantee.

Limitations, plainly:

• It is not in the WordPress.org directory yet; you download it from silotree.io.
• It never writes into pages built with Elementor, Divi, Beaver Builder, Bricks, Oxygen, WPBakery, Avada or Thrive Architect. It reads them, but you add those links yourself.
• Suggestions by meaning (AI) and auto-approve are paid plans only.
• White-label reports are not available yet.
• Wording is tuned for seven languages (English, German, French, Spanish, Italian, Dutch, Portuguese). Other languages get the audit, but suggestion wording is not tuned.
• It only wraps words already in your sentence. If the right phrase is not there, it suggests nothing — LinkBoss can do more here.

Best for: blogs and content sites with a few hundred posts or more, where the missing links are in the old posts and you want each one written into the post, reviewed, and reversible.

How to choose

Start from your situation, not the feature list. If you would rather answer a few questions than read a table, the free internal linking plugin picker asks about your site and budget and will recommend another tool where it fits better. Otherwise, here are three worked examples, at the prices above:

Then use the rules below. Where two apply, the first one wins.

1. You need a full technical audit, not links

   Screaming Frog. The free version covers up to 500 URLs.

2. One site, no budget, and you know which keywords should link where

   Internal Link Juicer free. Set per-post limits and check a sample of pages after the first run.

3. You already pay for Rank Math, Yoast Premium or AIOSEO Pro

   Use its suggestions for new posts for a month before buying anything else.

4. You want to hand-pick every link, across many sites

   Link Whisper, whose 50-site plan is the strongest value for heavy manual work.

5. You want volume, and AI-written sentences in your posts are acceptable

   LinkBoss.

6. Your sites are not all WordPress

   LinkStorm or Linkbot — knowing the links are added by a script.

7. A large archive, links written into posts, every one reviewed and reversible

   Silotree — unless your pages are built with a page builder.

Whatever you choose, the links that move the needle are the ones in your writing, not your menus — the distinction is covered in contextual versus navigational links. And whichever tool picks the words, read our anchor text guide before you switch on any automatic rule.

What to check before you buy

Five questions decide whether a tool fits a particular site better than any feature grid. Ask the vendor if the answer is not on their site.

1. Where do the links live? In the post, in a render-time filter, or in a script? The diagram above shows why it matters at renewal time.
2. What happens when you uninstall? Link Whisper and LinkBoss say their links stay. Internal Link Juicer’s links go with the plugin. For script-based tools, ask what happens when you stop paying.
3. Does it work with your page builder? Tools that write into post content may not reach text stored in a builder’s own layout data. Internal Link Juicer Pro lists page-builder compatibility; Silotree does not write into builder layouts at all. Test on one page before a bulk run.
4. Does it handle your languages? Keyword rules work in any language you type them in, but suggestion quality varies, and multilingual setups with WPML or Polylang need links kept within one language. Ask before buying for a non-English site.
5. Can you undo a batch? Bulk tools change hundreds of posts in one go. Rank Math’s bulk updates have preview and rollback; Silotree undoes any batch. With any tool, make sure WordPress revisions are on and take a backup before the first bulk run.
