Broken Link Checker explained

Detect potentially broken links — one of 2,142 free utilities on this site. It belongs to the Content SEO group inside SEO Tools.

Because everything runs client-side, it also works for confidential material — client drafts, unreleased campaigns, internal data — with nothing transmitted or logged.

Using the Broken Link Checker — step by step

1. Paste your HTML or content into the input box.
2. Press Analyze — the checker parses your input in your browser.
3. Review the pass/warn/fail table and fix the flagged items.

Broken Link Checker — FAQs

Why the Broken Link Checker matters

Most content seo work stalls because the answer lives in a spreadsheet tab, a paywalled dashboard, or a colleague's head. The Broken Link Checker removes that friction: open the page, enter what you know, and get a usable answer in seconds.

Learning by doing beats learning by reading. Paste real material into the Broken Link Checker, watch how the results change with your edits, and you build intuition for content seo that no course can teach.

Manual checks are fine once, but nobody repeats a manual checklist reliably. The Broken Link Checker encodes the checklist once and applies it identically every time you run it.

Common use cases

• t => `Teaching: juniors learn standards faster when a table says PASS or FAIL with reasons.`
• t => `Post-mortems: checking whether the version you shipped matches the checklist you promised.`
• t => `Agency handovers: documenting the state of deliverables with an objective pass/warn table.`
• t => `Competitor reviews: analyzing publicly available pages to see what they do well.`
• t => `Client onboarding: producing a fast, visual assessment of the assets you inherited.`

Broken Link Checker tips that save time

• t => `Keep the results table in your QA doc; a dated record of pass/fail states makes regressions obvious weeks later.`
• t => `If every row fails at once, check that you pasted complete markup — a truncated copy produces misleading results.`
• t => `Re-run the ${t.name} after every fix — the pass/warn table should shrink visibly between runs, which is your proof of progress.`
• t => `Paste the final rendered version of your content (what users actually see), not the draft with placeholders.`
• t => `Analyze a representative sample, not a cherry-picked snippet — the ${t.name} can only report on what you paste into it.`

What goes wrong with content seo — and how to prevent it

• t => `Optimizing for the checker instead of the user — the table guides priorities, it does not replace judgment.`
• t => `Fixing rows without re-running; unverified fixes have a way of not being fixes at all.`
• t => `Ignoring repeated patterns across pages: one page's FAIL is a template, and templates deserve one fix in one place.`
• t => `Analyzing a staging page with placeholder content and expecting production-relevant results.`

Content SEO glossary: the terms that matter

• Schema markup — JSON-LD structured data that helps search engines and AI answers understand and cite your page.
• Readability score — an estimate of how easily text is understood (e.g., Flesch); lower grade levels reach wider audiences.
• Dwell time — how long a visitor stays before returning to results — a soft signal of content satisfaction.
• CAC — Customer Acquisition Cost — total sales + marketing spend divided by customers gained.
