My company has been working on a large link building project. We’ve already performed extensive keyword research and link analysis and now we’re considering executing an email outreach campaign. However, all the content we’ve created up until this point is geared more towards our target audience as opposed to the key influencers of our target audience. Do you think it would be worth it to try to build backlinks to our existing content or are we better off creating new content that directly appeals to the influencers of our target audience?
I’d add one thing to number 5: Writing good copy is crucial not just for your Title/snippet, but for your whole page, especially your landing page. You want people to stay on your page for a while and (hopefully) even navigate to other pages you have. Google looks at bounce rate and where they go after they hit your page. Learning to write good copy can not only increase conversion (if you’re selling something) but make your content more impactful and engaging. There are free books at most libraries or online to help.
Headlines are one of the most important parts of your content. Without a compelling headline, even the most comprehensive blog post will go unread. Master the art of headline writing. For example, the writers at BuzzFeed and Upworthy often write upward of twenty different headlines before finally settling on the one that will drive the most traffic, so think carefully about your headline before you hit “publish.”
While most search engine companies try to keep their processes a secret, their criteria for high spots on SERPs isn't a complete mystery. Search engines are successful only if they provide a user links to the best Web sites related to the user's search terms. If your site is the best skydiving resource on the Web, it benefits search engines to list the site high up on their SERPs. You just have to find a way to show search engines that your site belongs at the top of the heap. That's where search engine optimization (SEO) comes in -- it's a collection of techniques a webmaster can use to improve his or her site's SERP position.
Content is king. That’s the saying, right? It’s true in a way. Your website is really just a wrapper for your content. Your content tells prospects what you do, where you do it, who you have done it for, and why someone should use your business. And if you’re smart, your content should also go beyond these obvious brochure-type elements and help your prospective customers achieve their goals.

By 2004, search engines had incorporated a wide range of undisclosed factors in their ranking algorithms to reduce the impact of link manipulation. In June 2007, The New York Times' Saul Hansell stated Google ranks sites using more than 200 different signals.[26] The leading search engines, Google, Bing, and Yahoo, do not disclose the algorithms they use to rank pages. Some SEO practitioners have studied different approaches to search engine optimization, and have shared their personal opinions.[27] Patents related to search engines can provide information to better understand search engines.[28] In 2005, Google began personalizing search results for each user. Depending on their history of previous searches, Google crafted results for logged in users.[29]

Website owners recognized the value of a high ranking and visibility in search engine results,[6] creating an opportunity for both white hat and black hat SEO practitioners. According to industry analyst Danny Sullivan, the phrase "search engine optimization" probably came into use in 1997. Sullivan credits Bruce Clay as one of the first people to popularize the term.[7] On May 2, 2007,[8] Jason Gambert attempted to trademark the term SEO by convincing the Trademark Office in Arizona[9] that SEO is a "process" involving manipulation of keywords and not a "marketing service."
