Uncle Google can impose to our website two types of filters:

More about them: 

Usually, if manual filter will be applied on your website, you will see this information on special panel for webmasters. When it comes to algorithmic filters, it is quite easy to find out, when alghorithmic filter has been applied on your website. You look at a date on which you have noticed a significant decrease in the position of your website. If the date responds to one of Panda or Penguin update, then you already know that kind of rule you have broken: typically, it is something with unnatural linking or with content. Algorithmic filters are harder to remove than the manual filters, but the second ones, are more difficult to detect, because you can be not informed about them at all The period of the imposition of filter (both manual and algorithmic) can range from six months to over a year.
