How to know if their site has a Google penalty Penguin

The calendar of updates

For the following analyzes, be careful to consider the specific dates:

Google made ​​an update of Panda (v3.5) April 19, 2012, widely discussed on the forum Gastronomie.
Updating Penguin took place April 24, 2012 (or rather the 25th for us in France)
A new Panda update (v3.6) has been in place since April 27, 2012, unusually close to the previous (there are usually 4-6 weeks)

You could very well have been concerned only with Panda and do you notice it until later.

Also, Google has penalized some network links in the month of March 2012. If ever enjoyed your website backlinks to these networks, your visibility may have fallen in the days and weeks that followed.

Finally, Google has sent no less than 700,000 warnings in Google Webmaster Tools tells the webmaster concerned that Google had spotted backlinks artificial (see end of article an example of a message sent by Google). For now there has not been shown if there was a direct link or not between these messages and update the Penguin. Indeed, I met many cases of sites being penalized by Google penguin and having yet received any warning for fake links in GWT.

Analysis of the positioning

f you take care to regularly monitor your ranking on multiple requests (a few dozen at least), so through an analysis of position now that Penguin, you can measure if your visibility is generally stable, rising or falling.
Confirm this analysis by comparing the evolution of positioning Bing example.

If you do not have a tool at hand, it will be harder, especially if you have not noticed history. However, you can test some queries manually to see where your site. In this case take the ones you brought the most traffic so far. Remember to disable your cookies (or easier, to use private browsing) to avoid bias introduced by the personalized search.

To complete the analysis of ranking if your site comes out even more about his own name, it is likely that the Penguin is there for something ...

Traffic Analysis

To complete the analysis above, look in your audience measurement tool that has happened in terms of traffic from Google natural search. Do not forget to focus primarily on off-brand traffic. Compare daily  (equivalent day of the week before) taking into account possible side effects (events, weather, etc..).

Analysis of indexing

The only time your site disappears completely when Google penalty is when your site is blacklisted. Know that this is really rare and must have really tried!

For all other penalties from Google, manual or algorithmic, the pages of your site are indexed
