Hello,
Google Penguin
Google Penguin is the latest update to Google's algorithm. This update is aimed at websites that are using tactics that are considered a way to game Google's searches. When Google indexes a site, it looks at places for specific keywords, some firms have used this fact and stuffed keywords onto a site, or hidden text from the user, but make it visible to Google, or they get lots of links from illegitimate websites that Google now consider to be spam. To date, we have not reviewed a site that has been hit by Penguin. Most of the sites we review end up suffering from a lack of updating or issues relating to Google Panda.
Google Panda
Google Panda is the change to the algorithm we see that effects a lot of people who have old sites. To understand Google Panda, it helps to understand Google's core mission. Google wants to deliver the best results for what you are searching. They do not want to deliver websites they consider to be low quality and this means when people go to a site from Google's search, if you go back from that search, Google notices it and pushes you down in the search rankings. Some of the factors we have seen effect sites, are poor site design, sites that don't reference their articles through links, sites that are slow to load, sites that use duplicate content over and over again. The bottom line is you need to have a well designed site and creates original content.
So, in conclusion, Panda is about getting Google to deliver the best quality websites to your search results. Penguin keeps people from gaming the system.
