Weekly Website Readability Audit (n8n) w/ Snapshot Site, Sheets & Slack

Spot readability problems on your website every week—automatically.

This Weekly Website Readability Audit (n8n) workflow pulls a URL list from Google Sheets, runs each page through Snapshot Site Analyze (with quality checks on and AI summaries off), updates one audit row per URL, and posts a ranked readability report to Slack every Monday at 7AM.

What this workflow does

• Runs on a schedule: executes every Monday at 7AM.
• Reads URLs from Google Sheets: retrieves url, label, and contentType from the “Content Library” tab.
• Audits pages one at a time: calls Snapshot Site Analyze for each URL with quality checks enabled and AI summaries disabled.
• Detects unreadable pages: marks pages as unreadable when the page renders blank or shows a CAPTCHA.
• Calculates readability + flags key issues: uses the Snapshot Site response to compute a readability band, stores a readabilityScore, and flags title, meta description, and H1 issues (via the issue signals in the same response).
• Writes results back to Sheets: appends or updates a single audit row in “Readability Audit” using url as the matching key.
• Posts a ranked Slack summary: compiles a worst-to-best report including band counts plus unreadable/failed pages.

Use cases

• Weekly monitoring of blog and landing page readability for SaaS content teams.
• Ongoing SEO hygiene checks (title/meta/H1) to catch regressions early.
• Operational reporting in Slack so stakeholders can review priority pages without digging into spreadsheets.

Technical details

• n8n nodes/tools: if, set, code, Slack, sticky note, Google Sheets.
• Snapshot Site integration: uses the community node n8n-nodes-snapshot-site and Snapshot Site API credentials.
• Google Sheets tabs/columns: expects “Content Library” headers url, label, contentType and “Readability Audit” headers including url, label, contentType, status, readabilityScore, band, needsWork, and issue counts.
