Fantastic stuff, as usual, Brian. The First Link Priority Rule is always one that causes me great angst. I often get torn between search engines and usability when it comes to the main navigation bar. And, I’ve never known what the heck to do about the “Home” link. You can hardly target your keywords with that one without it being anything but awkward.
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.
Like you I am a scientist and like you did in the past, I am currently working on translating great scientific literature into tips. In my case it’s child development research into play tips for parents. I can already see that the outcome of my experiment is going to be the same as yours. Great content but who cares. I hadn’t even thought about my key influences. I know some important ones, but don’t see how they would share my content. I thought I was writing content for my potential customers. Is your SEO that works course the same as the content that gets results course? Sorry if I sound a bit dim asking that question.
SEO is not an appropriate strategy for every website, and other Internet marketing strategies can be more effective, such as paid advertising through pay per click (PPC) campaigns, depending on the site operator's goals. Search engine marketing (SEM) is the practice of designing, running and optimizing search engine ad campaigns. Its difference from SEO is most simply depicted as the difference between paid and unpaid priority ranking in search results. Its purpose regards prominence more so than relevance; website developers should regard SEM with the utmost importance with consideration to visibility as most navigate to the primary listings of their search. A successful Internet marketing campaign may also depend upon building high quality web pages to engage and persuade, setting up analytics programs to enable site owners to measure results, and improving a site's conversion rate. In November 2015, Google released a full 160 page version of its Search Quality Rating Guidelines to the public, which revealed a shift in their focus towards "usefulness" and mobile search. In recent years the mobile market has exploded, overtaking the use of desktops, as shown in by StatCounter in October 2016 where they analyzed 2.5 million websites and found that 51.3% of the pages were loaded by a mobile device . Google has been one of the companies that are utilizing the popularity of mobile usage by encouraging websites to use their Google Search Console, the Mobile-Friendly Test, which allows companies to measure up their website to the search engine results and how user-friendly it is.
