If you don’t want your Google traffic dropped dramatically due to indexing and content pruning, we are going to list below the steps you need to take in order to successfully prune your own content. We’ve developed this subject in a previous blog post. Yet, before doing so, we want to stress on the fact that it’s not easy to take the decision of removing indexed pages from the Google Index and, if handled improperly, it may go very wrong. Yet, at the end of the day, you should keep the Google Index fresh with info that is worthwhile to be ranked and which helps your users.
As I mentioned earlier, one of the biggest downsides to SEO is that Google is constantly making changes to their algorithm; they come out of nowhere, and they can drop your domain authority by 5, 10, even 15 points and it almost feels like you need to start optimizing all over again. It's frustrating, it's hard work and the results aren't always visible - but if you can get SEO right, it can truly be an amazing source of traffic.
Great post, though http://www.blogcatalog.com that sends millions of visits a month to blogs and has an engaged community of bloggers from startup bloggers to pros should be on any list. BlogCatalog is the parent company of http://www.bloggersunite.org a site dedicated to harnessing the power of the blogosphere and another great site for bloggers to connect and get traffic and become more effective bloggers.
Users land on this page without tracking code. They click on a link to a deeper page which does have tracking code. From GA’s perspective, the first hit of the session is the second page visited, meaning that the referrer appears as your own website (i.e. a self-referral). If your domain is on the referral exclusion list (as per default configuration), the session is bucketed as direct. This will happen even if the first URL is tagged with UTM campaign parameters.
Google claims their users click (organic) search results more often than ads, essentially rebutting the research cited above. A 2012 Google study found that 81% of ad impressions and 66% of ad clicks happen when there is no associated organic search result on the first page. Research has shown that searchers may have a bias against ads, unless the ads are relevant to the searcher's need or intent 
WOW Brankica, cannot believe that you also includes Craigslist.org on your list! What a great post, indeed. ;) Elise add #51 email list building, so I would add #52 rss feed submission, #53 review websites like resellerratings.com, reviewcentre.com, etc., #54 blog search engine like Technorati, plus I have about 40 video websites where you can upload and share your video like break.com, blip.tv. Good luck with the contest. ;)
Absolutely nothing (other than the scale of the challenge). Google doesn’t care whether you’re a startup, a major financial institution or the smallest online retailer – all it cares about is connecting people with the most relevant content for each search query. The SEO requirements for a startup are exactly the same as the world’s biggest brands and search engines want to see the same things from you as any other kind of business.
To sum up all of this information, even organic traffic, like direct traffic, has some gray areas. For the most part, though, organic traffic is driven by SEO. The better you are ranking for competitive keywords, the more organic traffic will result. Websites that consistently create content optimized for search will see a steady increase in organic search traffic and improved positioning in the search results. As a marketer, it is important to look at your keywords and high-ranking pages to identify new SEO opportunities each month.
