TL;DR
I created PageRadar because I was tired of discovering SEO issues only after my rankings had already dropped. It's a monitoring tool that alerts you instantly when critical changes happen on your website - before they impact your search visibility.
The Problem That Led Me Here
As a developer and founder, I've experienced the nightmare scenario too many times: You deploy a seemingly innocent update, everything looks fine in staging, but two weeks later you notice your organic traffic has tanked. After hours of investigation, you discover that:
- Someone accidentally changed the robots.txt and blocked important pages
- A deployment broke your Core Web Vitals scores
- Your sitemap stopped updating properly
- Meta descriptions got truncated during a CMS migration
- Affiliate links started returning 404s in certain countries
The worst part? Google had already noticed these issues and adjusted your rankings accordingly. You're now playing catch-up, trying to recover lost positions.
Enter PageRadar: Prevention Over Recovery
Instead of discovering issues through ranking drops, PageRadar monitors your website 24/7 and alerts you the moment something changes. Think of it as continuous integration testing, but for SEO.
🎯 Key Features That Developers Will Love
1. Core Web Vitals Monitoring
What it tracks:
- LCP (Largest Contentful Paint)
- INP (Interaction to Next Paint)
- CLS (Cumulative Layout Shift)
- TTFB (Time to First Byte)
- PageSpeed scores
Why it matters: These are actual Google ranking factors.
One bad deployment can tank your scores.
2. HTML Element Monitoring
Ever had someone "optimize" your title tags and accidentally delete half of them? PageRadar tracks changes to:
- Title tags
- Meta descriptions
- H1-H6 headings
- Canonical URLs
- Schema markup
- Open Graph tags
You get instant alerts when any of these elements change, with a before/after comparison.
3. Robots.txt & Sitemap Monitoring
// Example alert:
"Your robots.txt was modified:
- Added: Disallow: /api/*
- Removed: Allow: /products/
Impact: 2,341 product pages may become inaccessible to search engines"
4. HTTP Status Monitoring
Monitor critical pages for status code changes. Perfect for:
- Catching accidental 404s after deployments
- Detecting 500 errors before users complain
- Tracking redirect chains that slow down your site
5. Affiliate Link Checker (167 Countries!)
This one's unique - test your affiliate links from 167 different countries. Essential if you're running:
- Amazon affiliate programs (different stores per country)
- Geo-targeted campaigns
- International e-commerce sites
6. AI Overview Tracking
With Google's AI Overviews taking over SERPs, PageRadar tracks:
- When AI Overviews appear/disappear for your keywords
- How they impact your visibility
- Changes in SERP features over time
🛠️ Technical Implementation
PageRadar runs distributed checks from multiple locations to ensure accuracy. Here's what happens under the hood:
- Scheduled Monitoring: Checks run at intervals you define (hourly, daily, weekly)
- Smart Diffing: We use intelligent algorithms to detect meaningful changes, not just any change
- Instant Alerts: Notifications via email, Slack, or webhook when issues are detected
- Historical Data: Track changes over time with full history retention
