I have gotten this a lot lately so I thought I’d drop a quick post about it.

Google Penalty

1. Dig your internal traffic analytics for traffic drops or bad trends;
2. Perform [site:yoursite.com] search in Google to see if Google reports same number of indexed URLs;
3. Check if Google Webmaster Tools report any problems;
4. Take a look if Google toolbar PR has changed (graybar PR might be a signal of penalty);
5. Check your site ranking for a “domain-name” search (without the TLD).

If such a query puts you in the fifties, it’s almost (!) guaranteed to be a penalty.

6. Check if Google has blacklisted your site as unsafe for browsing (type http://www.google.com/safebrowsing/diagnostic?site=mysite.com with your domain at the end).
7. Check the source code for any injected links to obvious “bad neighborhood” sites;
8. Check your other sites. In some cases Google seems to devalue the WHOIS domain owner and this results in a simultaneous ranking drop in several sites under the same domain account.
9. Copy a long phrase from your page and search Google for the exact match – make sure this very page (not the home page, not other sites scraping yours) is ranked #1;
10. Check if your URL can only be seen by adding &filter=0 to the search URL – or clicking on the “show omitted results” link (this means you were hit by the duplicate content penalty);
11. Any other? Please share your way to diagnose a penalty.
