Expert roundups have been abused in the Internet Marketing industry, but they are effective for several reasons. First, you don’t have to create any content. The “experts” create all the content. Second, it is ego bait. Meaning, anyone who participated in the roundup will likely share it with their audience. Last, it is a great way to build relationships with influencers.
Create shareable content. In the world of social media, shareable content is king. Your content should be easily share-able so that your readers can spread the word for you. This is a combination of a good headline and an interesting image, as well as a captivating lead-in. All of this creates a perfect bite-sized chunk of your article that others can share through Facebook, Twitter, and other networks.[2]
Getting traffic is always important but one should not worry too much, nothing happens in overnight, Now I read this article and genuinely tried to make my own impression about the post which automatically creates a link to my blog but don’t try hard thinking back links in mind, you always get caught in some or the other way, Panda and Penguin are one such examples.

There is no magic formula for content marketing success, despite what some would have you believe. For this reason, vary the length and format of your content to make it as appealing as possible to different kinds of readers. Intersperse shorter, news-based blog posts with long-form content as well as video, infographics and data-driven pieces for maximum impact.
An SEO technique is considered white hat if it conforms to the search engines' guidelines and involves no deception. As the search engine guidelines[18][19][52] are not written as a series of rules or commandments, this is an important distinction to note. White hat SEO is not just about following guidelines but is about ensuring that the content a search engine indexes and subsequently ranks is the same content a user will see. White hat advice is generally summed up as creating content for users, not for search engines, and then making that content easily accessible to the online "spider" algorithms, rather than attempting to trick the algorithm from its intended purpose. White hat SEO is in many ways similar to web development that promotes accessibility,[53] although the two are not identical.
“Syndicate carefully: If you syndicate your content on other sites, Google will always show the version we think is most appropriate for users in each given search, which may or may not be the version you’d prefer. However, it is helpful to ensure that each site on which your content is syndicated includes a link back to your original article. You can also ask those who use your syndicated material to use the noindex meta tag to prevent search engines from indexing their version of the content.”

I consulted a few years ago before Yahoo and CNET and my clients were all small businesses, even friends' sites.  No matter the size of the project, you can still try to get some insight into your target audiences and what they need or want.  I mentioned in a previous comment I used Search once to determine sentiment on a site vs. it's competitors by searching for a feature the site and its competitors all had, along with "like", "love", "hate", "wish", etc.  I also took note of who the people were who said those things and where they were talking (forums, twitter, etc).  It's a hacked manual approach and although not nearly as quality as a good market research report, at least I have a llittle bit of insight before going out to make site recommendations based solely on tags & links.  If you're recommending the site build things that people want (and fix or remove things that they dont), you're more likely to gain links and traffic naturally.

Hi there, am interested to try your trick in Wikipedia, but am also not sure of how should I do tht, coz i read some posts saying tht “Please note that Wikipedia hates spams, so don’t spam them; if you do, they can block your IP and/or website URL, check their blocking policy and if they blacklist you, you can be sure that Google may know about it.”
Black hat SEO attempts to improve rankings in ways that are disapproved of by the search engines, or involve deception. One black hat technique uses hidden text, either as text colored similar to the background, in an invisible div, or positioned off screen. Another method gives a different page depending on whether the page is being requested by a human visitor or a search engine, a technique known as cloaking. Another category sometimes used is grey hat SEO. This is in between black hat and white hat approaches, where the methods employed avoid the site being penalized but do not act in producing the best content for users. Grey hat SEO is entirely focused on improving search engine rankings.
