Hey Ashok! Good question. I work with clients in a lot of different industries, so the tactics I employ are often quite different depending on the client. In general though, creating killer resources around popular topics, or tools related to client services. This provides a ton of outreach opportunity. For example: We had a client build a tool that allowed webmasters to quickly run SSL scans on their sites and identofy non-secure resources. We reached out to people writing about SSLs, Https migration etc and pitched it as a value-add. We built ~50 links to that tool in 45 days. Not a massive total, but they were pretty much all DR 40+.
Secure (https) to non-secure sites (http): Since Google began emphasizing the importance of having a secure site, more websites are securely hosted, as indicated by the “https” in their URLs. Per the security protocol, however, any traffic going from a secure site to a non-secure site will not pass referral information. For this issue, you can correct by updating your site to be secure through a third-party SSL certificate.
There’s also other search engines. Ask, Dogpile, IxQuick, and so forth; these are all minor. However, one search engine seems to be gaining market share and exposure, and that’s DuckDuckGo. It has been trending in the wake of Google privacy concerns and some clever marketing from the DDG staff. It’s something you should, at least, pay some attention to.

People who use the ambiguous phrase “social media marketing” are typically referring to advertising: you broadcast your message and hope people will listen. Even if you overcome consumer indifference with a well-targeted campaign, any subsequent interactions are affected by their very public nature. The privacy of dark social, by contrast, represents a potential goldmine of intimate, targeted, and relevant interactions with high conversion potential. Nebulous and difficult-to-track though it may be, dark social has the potential to let marketers tap into elusive power of word of mouth.
For our client: We rolled out numerous new pieces of content onto their blog and news section; we aimed to make the content creative and funny. As the client was in the careers space we made use of “funny interview questions” and “technical interview questions” style articles. It was amazing that one of the articles even made it to the first page of Reddit. We also pushed out content which was related to various holidays in that year and also specific to the client’s industry and also current trends in the market. 
Though a long break is never suggested, there are times that money can be shifted and put towards other resources for a short time. A good example would be an online retailer. In the couple of weeks leading up to the Christmas holidays, you are unlikely to get more organic placement than you already have. Besides, the window of opportunity for shipping gifts to arrive before Christmas is ending, and you are heading into a slow season.
Hey Don, that is a great question and I will give you the overview. Now I have been trying these out for almost two years, for example Yahoo Answers was one of the first ones I tried and brought great results then. So first you need to decide which ones will you try and then track the results. I use Google Analytics to track the incoming traffic. So if I am focusing for example on blog commenting, I will note where I commented, how many times, etc and then see if those comments brought me any traffic. It depends a lot on the type of comment I make, the title of my ComLuv post, but you can still get some overview of how that traffic source is working for you. There are of course sources I discover "by chance". For example, in the last month Paper.li brought me 24 visitors, that spent more than 2 minutes on average on my blog. That is more than some blogs I comment on regularly bring me. So in this case, I will try to promote the paper.li a bit better and make it work for me. I will unfollow some people on Twitter that are not tweeting anything good so my paper.li chooses better posts hence better tweeps and get me exposed to them. A lot of them will RT my paper.li daily, so there is more potential of my content being shared. In case of the blog I mentioned, since none of the posts are becoming viral, the blogger is average, it is obviously not bringing me any traffic, I will start commenting less and work more on those that bring me more traffic. Now this is all great, except I get emotionally attached to blogs I read so I don't look at numbers like that :) But that is how you should track results. The main thing after reading this post is to choose up to 5 of these sources you feel comfortable with, work on them and track results. Keep those that work for you and ditch those that don't. It is a lot dependent on the niche you are in, too. I always try one source for up to a month, if there are no results in a month, I stop working on it and move to another one. If I didn't answer all you wanted to know, just ask additional questions, I am more than glad to help :)
I have always believed in good quality content, well structured and written in a way that isn’t just about promotional talk. Thanks for sharing this information with us, it’s always helpful to have everything written in a concise manner so we can remind ourselves now and again of what it takes to increase organic traffic. As an SEO consultant myself I come across websites all the time that are messy and still using tactics that have long been out of date. Having a successful website is all about quality content and links. I like it that you stated what the problem was and then how you fixed it for the client. Great article.
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.
About.com – How many times have you tried to do something and needed instructions? You Google it and it brings up how-tos from About.com. Well, you can contribute to this site with some of the how-tos for your niche and get traffic from it. Additional tip – there is an About.com Forum where you can be helpful to people in need and get additional traffic to your blog.

Because so few ordinary users (38% according to Pew Research Center) realized that many of the highest placed "results" on search engine results pages (SERPs) were ads, the search engine optimization industry began to distinguish between ads and natural results.[citation needed] The perspective among general users was that all results were, in fact, "results." So the qualifier "organic" was invented to distinguish non-ad search results from ads.[citation needed]
Reddit is also worth a special mention here. It’s a cross between a social network and a web forum, which is a traffic source we’ll discuss later. Reddit is one of the largest sites online, and the entire focus of the site is based around posting links and discussing the content of those links. A lot of the content you see trend on Facebook or Twitter is trending because Reddit got hold of it and started engaging with it. However, Reddit is a very tricky platform to use for marketing. You have to avoid approaching it like a marketer, because Reddit users are like piranhas. If they sense you trying to use their audience for money, they’ll swarm you and savage you until you feel like you can’t use the site again. Make sure to read up and take great care before trying to market on Reddit.

Thus, resulting in wasted marketing efforts and investment.
