FREE Broken Link Checker

Paste your page HTML or a list of URLs to extract, categorise, and validate every link — detecting malformed URLs, HTTP links, dead domains, redirect patterns, and syntax errors instantly.

How It Works

No browser extensions, no crawling, no API. Paste your source and get results in under a second.

1. Paste HTML or URLs

   Paste your page's full HTML source (right-click → View Source, then Ctrl+A, Ctrl+C) or switch to URL List mode and paste one URL per line. Load the sample to see what it checks.

2. Instant Link Audit

   Every href, src, and action attribute is extracted and checked: malformed syntax, literal spaces, HTTP links, dead domains, double-slash paths, redirect patterns, and missing protocols.

3. Filter and Export

   Filter by error, warning, type (external, relative, anchor, email), or search by URL. Export the full audit as a CSV for your SEO report or to share with a developer.

Our content plan writes itself and aligns over our exact needs. We approve once a week, and the rest runs. It’s the first AI SEO tool that feels trustworthy. RECOMMENDED!!!

Sarah Gonzales

Digital Growth VP
For small teams, Keytomic feels like hiring a full-time SEO operator at the cost of lunch-out weekly. Highly recommended for scalability in content and research teams.

Hannah Greene

CMO
We tried a few ‘autonomous’ AI SEO tools. This is the only one we kept. Minimal inputs, reliable publishing, and verifiable wins in both AI answers and search.

Ksenia Ivanova

Content Director
We tested Keytomic in the beta stage for 90 days and our mid-tail keywords climbed 30 places. It’s not perfect, but for automated content roll-out it gets the job done. Best of luck for the launch.

Aisha Zafar

Founder & CMO
If you’re looking for a full hands-off On-page SEO growth machine, Keytomic gets you 80% there. You’ll still need some final checks to polish the last 20% in terms of dates and schedule approval, but the volume boost is real.

Miguel Santos

Head of Organic Growth
We used to spend half my week wrangling writers, keyword research, strategies, and whatnot. Now with Keytomic, it's clicks-to-publish in under an hour. Our content pipeline is always full and we require little oversight. My only regret is not starting earlier.
