LinkStorm
LinkStorm is a platform-agnostic internal linking SaaS that crawls a site, uses AI to find contextual linking opportunities, and lets you implement them in one click or hand the job to an auto-linking mode. It pulls Google Search Console data so suggestions are weighted toward pages that already have rankings and impressions, and it audits existing links for broken targets, redirects, and nofollow issues. Plans are priced on URL/credit volume with unlimited projects, which suits agencies managing several sites.
Full transparency: LinkStorm is our own product. It sits in this table on the same verified data as everyone else, and the tools below may fit you better — here's how to read this directory.

How to choose an internal linking tool
1. Start with what you have
If you already pay for Ahrefs, Semrush, or use Rank Math / Yoast, you already own an internal-linking feature. Search Console is free. Exhaust these before buying.
2. Decide how much automation you trust
Tools range from analysis only (crawlers), to suggestions you approve, to fully automated insertion. More automation saves hours but needs review — bad anchors at scale are worse than no links.
3. Match your platform
WordPress has the richest plugin ecosystem. Shopify, Webflow, custom stacks and headless CMSs need a platform-agnostic SaaS — usually via a crawl or a JavaScript snippet.
