Relevancy is the first qualifier of a quality link opportunity. The next qualifying factor is the authority of the opportunity. Since Google doesn’t update PageRank (PR) anymore, you must rely on third party metrics. I recommend you use Domain Authority (DA) from Open Site Explorer, Domain Rate (DR) from Ahrefs, or Trust Flow from Majestic to determine the quality of your link opportunities. You should use all three tools if you can.
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.
A variety of methods can increase the prominence of a webpage within the search results. Cross linking between pages of the same website to provide more links to important pages may improve its visibility. Writing content that includes frequently searched keyword phrase, so as to be relevant to a wide variety of search queries will tend to increase traffic. Updating content so as to keep search engines crawling back frequently can give additional weight to a site. Adding relevant keywords to a web page's metadata, including the title tag and meta description, will tend to improve the relevancy of a site's search listings, thus increasing traffic. URL canonicalization of web pages accessible via multiple URLs, using the canonical link element or via 301 redirects can help make sure links to different versions of the URL all count towards the page's link popularity score.
Spider-driven search engines such as Google®, Yahoo!® and MSN® use "robots" or "crawlers" to score websites across the Internet. Robots "spider/crawl" each site and "score" pages based on how relevant they are. A website's score or placement within a spider driven search engine is derived from hundreds of variables such as link popularity, density and frequency of keywords in page content, HTML code, site themes and more. You will want to focus many criteria in your SEO strategy to position yourself well among the major search engines. Here are two of the most influential factors:
“In conclusion, this research illuminates how content characteristics shape whether it becomes viral. When attempting to generate word of mouth, marketers often try targeting “influentials,” or opinion leaders (i.e., some small set of special people who, whether through having more social ties or being more persuasive, theoretically have more influence than others). Although this approach is pervasive,recent research has cast doubt on its value (Bakshy et al. 2011; Watts 2007) and suggests that it is far from cost effective. Rather than targeting “special” people, the current research suggests that it may be more beneficial to focus on crafting contagious content. By considering how psychological processes shape social transmission, it is possible to gain deeper insight into collective outcomes, such as what becomes viral.”
Social media is one of the most popular free marketing tools around, and plays a role in driving traffic to your website. Use Facebook, Instagram, and LinkedIn to promote blog posts and other useful pages on your website. This way you can turn your social media audience into website visitors, and draw traffic from their networks if you post shareable content.
