I am so glad you used those tips and obviously have great results from it. It is all about creativity, I guess. If you think of a new and fresh way of generating traffic, that not too many bloggers are using already, you are on a roll. And Flickr was one of those that were not over saturated with bloggers searching for traffic. Thanks for the feedback and can't see the results with new strategies :)
This is a great piece of work for references, lots of info on this, Answer sites have become less and less popular, but the you can really build your name on these sites such as forums, if you are consistent in answering questions frequently. Out of the points you have mentioned, I relay enjoy the "Guest Blogging" point, as this is a win win situation, not just putting out content on other websites, but also welcoming guest on my own site, giving readers a change and a different style of article, as everyone is unique in their own way. I'm actually posting an interview tomorrow with a well known name in the guest blogging. Whichever point one choices from above, consistency is the key, there is no point doing it once, but it should be done on frequently, and over time with patience you will start to see the rewards.
For a long time, digital marketers summed up the properties of direct and organic traffic pretty similarly and simply. To most, organic traffic consists of visits from search engines, while direct traffic is made up of visits from people entering your company URL into their browser. This explanation, however, is too simplified and leaves most digital marketers short-handed when it comes to completely understanding and gaining insights from web traffic, especially organic and direct sources.
