Google penguin is an update of the search engine algorithm, which has been rolled out for the first time on April 24, 2012. The difference between the Google panda updates and Google penguin, is that penguin updates mainly penalizes websites with irrelevant back links. For example, this could mean that a specific website has actually purchased back links and has not obtained them in a natural way. In addition, Google Penguin also punishes websites that use keyword stuffing, which is intentionally using the keywords way too often in an article as well as websites with duplicate content. A back link is a link from another website to your website.
Having an ecommerce website that is responsive means that it is adaptable to all the different formats in which it can be presented. This means that it can be viewable in a traditional desktop format, in a mobile format, as well as a tablet and iPad format. A responsive website resizes itself depending upon which type of device it is being viewed on. In this way, you only need to have one website that caters to all devices, whether they are desktop, smart phone, iPad or tablet. Since more than 60% of all web searches are now being conducted from mobile devices it only makes sense to be able to include those folks in our arena of information.
