What does Lemwatch monitor?

Lemwatch runs 20+ automated checks per site: uptime, response time, SSL/TLS expiry, domain expiry, DNS changes, sitemap health, broken links, content changes, SEO audits, mobile usability, security headers, and more.

Yes. The free tier monitors up to 5 sites. Pro is $19/month for 50 sites and Agency is $59/month for 100 sites, both with full feature access.

How is Lemwatch different from UptimeRobot or Pingdom?

Lemwatch bundles uptime, change detection, SEO audits, security scans, and a public API in one platform — features competitors charge separately for. It also includes team workspaces, white-labelled status pages, and a webhook system out of the box.

Does Lemwatch send alerts?

Yes. Lemwatch supports email, browser push, webhooks, and per-site notification routing so the right person hears about the right incident.

Is there a public API?

Yes. Pro and Agency plans get a public REST API with webhooks for sites, checks, incidents, and reports.

Robots.txt check

Fetches robots.txt hourly and alerts on syntax errors, disallowed indexable paths, or blocked search-engine bots.

Quick answer

We fetch /robots.txt, parse every User-agent / Disallow / Sitemap directive, and diff against yesterday. Any Disallow: / raises severity: critical.

What it checks

200 response on robots.txt
No accidental Disallow: /
Sitemap: directive present and points to a live sitemap
Non-standard directives flagged
Diff vs previous fetch

Where to find it in Lemwatch

Site details → SEO → Robots.

How to fix

If Disallow: / snuck in from a staging deploy, remove it and redeploy.
Add Sitemap: <full-url> so Google finds your sitemap.
Don't block CSS/JS — Google needs them to render.
Re-run.

FAQ

Is robots.txt enforced?

By honest crawlers only. It doesn't stop scrapers.

Can I have multiple sitemap directives?

Yes — list one per line.
