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.

Rotating content noise (visual + text diff)

Lemwatch scrubs rotating banners, timestamps, and random ads so they do not fire visual alerts.

Quick answer

Enable Scrub rotating noise on any visual monitor. Lemwatch samples the page 3 times back-to-back, treats anything that changed between samples as noise, and diffs only what stayed stable.

What it does

Captures 3 quick samples on each check run
Diffs samples against each other to identify volatile regions
Automatically excludes those regions from the change score
Applies only to that run — no permanent mask is stored

Where to find it in Lemwatch

Visual Monitoring → [page] → Advanced → Scrub rotating noise.

How to enable it

Open the page in Visual Monitoring.
Click Advanced → toggle Scrub rotating noise.
Save.
Next run captures 3 samples and auto-scrubs volatile regions.
Review the first alert after enabling to confirm noise is gone.

FAQ

Does this slow down checks?

Yes, ~2–3× longer per run. Only enable on pages with rotating content.

Does it replace ignore zones?

Complement, not replacement. Use ignore zones for known-noisy regions; scrubbing catches new noise.
