I completely agree that defintion of a target audience isa great first step, but would ask if adding in competitors to the analysis (mentioned here as a later step) helps draw out who your target audience would be via comparisons, i.e. showing who you are an who you are not - would be very interested to hear opinions on how this tactic can be used within the overall step in coordination with targeted keyword discovery.
In the real world, its not so easy. For example, I have 2 niches where I’m trying to use your technique. By keywords, its Software for Moving and Free Moving Quotes. I have 2 websites that related to each of them, emoversoftware.com (emover-software.com as initial, they linked together) and RealMoving.com ( for latter keyword). So, to begin with, none of those niches has Wikipedia articles, so your first suggestion will not work. But, in general suggestions, you are advising to get backlinks (of authoritative sites of course). But check this out – my site emover-software.com has only 4(!) backlinks (https://openlinkprofiler.org/r/emover-software.com#.VXTaOs9VhBc) and, however, listed as #1 (or #2) by my keyword. (moving software, software for moving, software for moving company). RealMoving.com has more than 600 backlinks and is way back in ranks ( 170 and up) by my keyword. Even though those sites have different competition, its still makes no sense! It doesn’t seem like Google even cares about your backlinks at all! I also checked one of my competitor’s backlinks, its more than 12000, however, his rank by keyword related to moving quotes even worse than mine!.

Maybe this feels a bit too scattershot for you. Buzzsumo also allows you to find and observe influencers. What are they sharing? By clicking the "view links shared" button, you'll get a display of all the unique pages shared. Sometimes "influencers" share all types of varying content crossing many topics. But sometimes, they're pretty specfic in the themes they share. Look for the latter in this competitive research stage.
What is the leadership like? What kind of culture do they cultivate? In smaller companies, the leaders tend to influence the culture. In larger companies, unfortunately, this can get lost. But if you have access to the leadership, spend some time learning about their vision. It should match up to the company's core values, but sometimes there are more gems locked in their minds.
You should build a website to benefit your users, and any optimization should be geared toward making the user experience better. One of those users is a search engine, which helps other users discover your content. Search Engine Optimization is about helping search engines understand and present content. Your site may be smaller or larger than our example site and offer vastly different content, but the optimization topics we discuss below should apply to sites of all sizes and types. We hope our guide gives you some fresh ideas on how to improve your website, and we'd love to hear your questions, feedback, and success stories in the Google Webmaster Help Forum1.
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."
This information hits the mark. “If you want your content to go viral, write content that influencers in your niche will want to share.” I love the information about share triggers too. I’m wondering, though, if you could share your insights on how influencers manage to build such vast followings. At some point, they had to start without the support of other influencers. It would seem that they found a way to take their passion directly to a “ready” world. Excellent insights. Thanks for sharing.
