Recently, there has been a lot of questions about what diversity means so i figured it is time to get a solid thread going. After the Peguin update, I believe that diversity is crucial and can make or break your SEO plan. I survived the Penguin update because I started diversifying after I was hit hard by the previous Panda update. So here it goes. First thing to keep in mind is that there are many different kinds of diversity (diversity within diversity). A lot of people think of only back link diversity. While that is important, there is so much more! I like to break diversity into a few different categories, and here they are: Backlink Diversity This is crucial and quite possibly the biggest aspect of link diversity. Google is looking for this, because a normal "white hat" site will be receiving all kinds of links. You shouldn't disregard any type of link. Also, it is important to have both do follow and no follow links, just like it is important to have high pr links and low pr links. It is also a smart idea to create link pyramids and link wheels with these links. Here are a bunch of different links you can use: Wiki Links Social Bookmarks Social Networks Forum Profiles Blog Comments Doc Sites PowerPoint Sites Statistic Sites Blog Networks/Guest Posts (If you know they are safe) Guest Books Homepage links EDU and GOV Links Article Directories Directory Submissions Web 2.0s Press Releases RSS Feeds Social Backlinks/Social Presence The next are of focus is your online social presence. Usually, popular sites will be talked about on the web. A lot of these will create a backlink to your site, but more importantly, they will help you create a strong social presence across the web. After the recent penguin update, this has become more important then ever. Here are some ways you can gain a social presence: Twitter Retweets Facebook Likes Pinterest Pins Google +1s Yahoo Answers Responses Youtube Videos Stumbleupon/Reddit/Digg Likes and Up votes Anchor Text Diversification Anchor text diversification needs to be applied to all of the above mentioned diversification methods. This can make or break you.
