So much traffic sources here, that I have not even come across. While there are the "most popular" ones, half of the sites you mentioned here are relatively new to me, so they all will be worth checking out. You are right about "forums" though, and although I am basically stuck with two (warrior and another that is unrelated), it does provide you some traffic provided as always, that you provide good feedback, help people, engage effectively with the community and of course, having a good and well structured signature :) Finally published :) Hopefully on your way to 300+ RTs, LOL
The following example shows a Client who receives 55% of their website traffic from Organic Search – typically this is a strong performance, but again this will vary greatly based on paid search. More important than the % is the number of sessions itself – this tells us how many visits (note: not unique visitors) we received through this channel. In this example, we have 7486 visits in 1 month that all came from organic searches.
How often should you go evaluate posts on your business blog? If you post multiple times a week, checking once every three months is a good rule of thumb. If you post only a few times a month, evaluating twice a year should do the trick. Remember, search engine algorithms evolve and change – and so will your keyword rankings, so set a calendar reminder for yourself or your online marketing manager to dig deeply into your search traffic and keyword rankings so you know exactly where you stand and where your biggest opportunities lie.
This traffic source comes from search engines like Google, Bing, and Yahoo. Remember, paid search ads or PPC (pay-per-click) advertising are not included within this source category. If you choose to run a paid advertising campaign for your business, it will not affect your website’s ranking within an organic search. Organic search is obtained through natural placement on search engine results, without paying for it, through search engine optimization best practices.
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 
I have that problem :) I read all day long sometimes, just to realize at 1 AM that I am supposed to post at 7 AM ( I try to keep the posting schedule) and I have nothing written! Do your blog posts first, if you can write a few in advance that is great, cause that way you can schedule them and feel more relaxed, not being under pressure. Then check out one of these recommended sites. With for example Yahoo answers, you can spend 10-15 minutes every day and answer 3 questions in that time. Out of those 3 one can have a link. Not too much effort but can bring nice results!
Well, yes and no. Sure, you can get hit with an algorithm change or penalty that destroys all your traffic. However, if you have good people who know what they are doing, this is not likely to happen, and if it does, it is easy (in most cases) to get your visits back. Panda and Penguin are another story, but if you get hit by those it is typically not accidental.
One of the things that makes social media a bit more attractive than search engine optimization is that you get to maintain a bit more control over your success. You can always find new ways of improving your strategy and you can learn from your mistakes and your wins so that you can improve your traffic in the future. The same can't really be said about SEO - although it's very clear what not to do, it's not always as clear exactly what strategies can help you improve your ranking.
It's a little awkward, so we'll get straight to the point: This Monday we humbly ask you to defend Wikipedia's independence. We depend on donations averaging about $16.36, but 99% of our readers don't give. If everyone reading this gave $3, we could keep Wikipedia thriving for years to come. The price of your Monday coffee is all we need. When we made Wikipedia a non-profit, people warned us we'd regret it. But if Wikipedia became commercial, it would be a great loss to the world. Wikipedia is a place to learn, not a place for advertising. It unites all of us who love knowledge: contributors, readers and the donors who keep us thriving. The heart and soul of Wikipedia is a community of people working to bring you unlimited access to reliable, neutral information. Please take a minute to help us keep Wikipedia growing. Thank you.
