Precision-engineered text readability checker for the modern web.
About Text readability checker
Text readability checker is the no-friction way to audit a page's SEO fundamentals directly in your browser. It reads the same HTML Googlebot reads, surfaces the meta and structural issues that typically cost rankings, and gives you an exportable checklist of fixes — without requiring an account, a paid subscription or an external server connection. Built for speed and privacy, Text readability checker fits naturally into pre-launch QA, monthly site audits and competitive research workflows.
Problems This Tool Solves
Missing or truncated title tags and meta descriptions silently cost click-through rate in search results. - Text readability checker measures each tag against Google's current display thresholds and warns you before something gets cut off in the SERP.
Open Graph and Twitter Card tags are easy to miss, and bad previews cost social shares. - Text readability checker validates every OG/Twitter tag and shows a live preview of how the page will render on Facebook, LinkedIn, X and iMessage.
Schema and structured-data mistakes block rich-result eligibility without any warning from Google. - Text readability checker extracts embedded JSON-LD, validates it against the current schema.org spec, and flags the exact field causing the problem.
Heading hierarchy issues (missing H1, skipped H2→H4) quietly hurt topic clarity. - Text readability checker maps the complete heading tree and flags skipped levels, empty headings and duplicate H1s.
How to Use
Paste the URL or HTML - Drop in a live URL or paste raw HTML for pre-publish checks.
Run the audit - The on-device parser reads every meta, canonical, OG, Twitter and heading tag in one pass.
Review flagged issues - Problems are grouped by severity with a human-readable explanation and a suggested fix.
Copy or export - Copy fixed tags straight into your CMS, or export the full audit as CSV/JSON.
Why This Tool Is Better
Sees what Googlebot sees - Parses rendered HTML using the same standards-compliant DOM parser a crawler would — no inference, no approximation.
Up-to-date thresholds - Character limits, schema rules and tag validation follow the current 2026 Google and schema.org specs.
Private by design - Your URLs and HTML stay on-device — critical for auditing staging environments, gated pages and sensitive client sites.
