How I Caught a Hidden Search Engine Penalty
A few months ago, one of my sites dropped 40% in traffic overnight. Panic mode. I spent days checking logs, crawling pages, and pulling my hair out. Turns out, Google had issued a manual penalty for 'unnatural links'—a link I bought from a sketchy PBN two years ago. I wish I had caught it earlier.
That’s why I built a simple radar: plug in a URL, and it scans for indexing issues, penalty signals, and blacklist status across multiple engines. It’s not a replacement for Search Console, but it’s a quick sanity check before you invest more time or money.
I use it before every new campaign now. Saved me from buying another bad domain last week.

• Look for sitemap indexes in robots.txt
• Some CMS platforms use /sitemap_index.xml
• WordPress often uses /wp-sitemap.xml
Missing sitemaps directly impact crawling efficiency. Googlebot might still find your pages, but it wastes crawl budget guessing.
That penalty radar is exactly the kind of quick check I've needed before buying expired domains. Just ran a test URL and it flagged a couple of warning signs I would've missed. Thanks for sharing this—saved me a headache already.
That's a great tool idea. One thing that helped me catch penalties early was setting up Google Search Console email alerts—works for manual actions and index coverage issues. Have you considered adding a feature to check for disavow file problems too?
Manual penalties are the worst kind of surprise—I had a similar scare with a shady guest post network. A quick health check tool like yours would've saved me a week of debugging. Thanks for sharing the radar link.
Thanks for stopping by! Glad the penalty radar resonated with you — it's really saved me from repeating that same costly mistake.
I can relate to that panic—had a similar drop last year from a bad link profile. Your radar tool is slick; I threw in a few domains I was considering and it caught one with a manual action I hadn't seen in Search Console. Great sanity check.
