SEO Monitoring and Alerts: Catching Problems Within Hours

A practical monitoring setup that catches SEO problems within hours: uptime and SSL checks, a daily smoke test with GitHub Actions, a robots.txt change alert, Search Console notifications and weekly trends.

Most serious SEO losses start with a change nobody noticed: a robots.txt rule, a noindex left on after a release, a CDN setting that blocks crawlers, a broken redirect, an expired certificate. Monitoring catches these within hours instead of weeks. A practical setup combines uptime monitoring, a daily automated check of key pages, a robots.txt change alert, Search Console notifications going to a watched inbox, and a weekly look at traffic and indexing trends.

What to monitor

Check Frequency How
Site up and responding Every few minutes Uptime monitoring service
SSL certificate expiry Daily Uptime service or certificate monitor
Key pages: status, noindex, canonical, title, H1, JSON-LD Daily Scheduled smoke test
robots.txt changes Daily Scheduled diff against a saved copy
AI crawler access through the CDN Weekly AI crawler access checker
Search Console issues As they happen Search Console email notifications
Clicks, impressions and indexing trends Weekly Search Console or a dashboard
Redirects After every release Redirect checker

A daily check with GitHub Actions

Run the SEO smoke test script against production every morning. If any key page regresses, the job fails and GitHub notifies the team:

# .github/workflows/seo-monitor.yml
name: SEO monitor
on:
  schedule:
    - cron: "30 2 * * *"        # 08:00 IST daily
  workflow_dispatch:
jobs:
  check:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-python@v5
        with:
          python-version: "3.12"
      - run: python3 seo_smoke_test.py monitor/urls.txt https://www.example.com
      - run: bash monitor/robots_diff.sh https://www.example.com

A robots.txt change alert

#!/usr/bin/env bash
# monitor/robots_diff.sh: fails if robots.txt differs from the approved copy
set -e
curl -fsS "$1/robots.txt" -o /tmp/robots_live.txt
if ! diff -u monitor/robots_approved.txt /tmp/robots_live.txt; then
  echo "robots.txt has changed. Review the diff above."
  exit 1
fi

When a change is intended, update the approved copy in the repository. The alert then only fires for unexpected changes, such as a staging file reaching production.

Search Console

  • Make sure notifications go to an inbox someone reads, not a former employee’s address.
  • Add owners and users carefully, and review them quarterly.
  • Check the Page indexing, Core Web Vitals and Security Issues reports weekly.
  • For larger sites, use the URL Inspection API to check key pages’ index status automatically.

What to do when an alert fires

  1. Confirm the problem on the live site.
  2. Check what changed recently: deployments, CDN settings, plugin updates.
  3. Roll back or fix, then re-run the check.
  4. Note the cause and add a test or safeguard so it cannot happen silently again.

Frequently asked questions

Is this necessary for a small site?

A small site benefits from the cheapest parts: uptime monitoring, Search Console emails and a weekly glance. Automated checks are a few hours of setup and protect against costly mistakes.

Which pages should the daily check cover?

The home page, one page per template, and the pages that bring the most enquiries or traffic.

Can WordPress sites use GitHub Actions?

Yes. The checks run against the live site from GitHub’s servers, whatever the site is built with.
