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. 

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.

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.
Google Analytics is free to use, and the insights gleaned from it can help you to drive further traffic to your website. Use tracked links for your marketing campaigns and regularly check your website analytics. This will enable you to identify which strategies and types of content work, which ones need improvement, and which ones you should not waste your time on.
Search engines may penalize sites they discover using black or grey hat methods, either by reducing their rankings or eliminating their listings from their databases altogether. Such penalties can be applied either automatically by the search engines' algorithms, or by a manual site review. One example was the February 2006 Google removal of both BMW Germany and Ricoh Germany for use of deceptive practices.[54] Both companies, however, quickly apologized, fixed the offending pages, and were restored to Google's search engine results page.[55]
Thanks for the great post. I am confused about the #1 idea about wikipedia ded links…it seems like you didn’t finish what you were supposed to do with the link once you found it. You indicated to put the dead link in ahrefs and you found a bunch of links for you to contact…but then what? What do you contact them about and how do you get your page as the link? I’m obviously not getting something 🙁

Stickers are essentially mini-posters, and advertisers have been using them for decades to get the word out without technically breaking the law. They hand them out to teams who then go out and plaster them over public buildings, bus stops and street signs. When the authorities complain, they say “oh, we only gave them to our customers. We have no control over where they put them.”
WOW. I consider myself a total newbie to SEO, but I’ve been working on my Squarespace site for my small business for about 3 years and have read dozens of articles on how to improve SEO. So far, this has been the MOST USEFUL and information-packed resource I’ve found so far. I’m honestly shocked that this is free to access. I haven’t even completely consumed this content yet (I’ve bookmarked it to come back to!) but I’ve already made some significant changes to my SEO strategy, including adding a couple of infographics to blog posts, changing my internal and external linking habits, editing meta descriptions, and a bunch more. Thanks for all the time and passion you’ve out into this.
In our research with what we have done for ourselves and our clients, there is a definite co-relation between content greater than 1000 words and better rankings. In fact, we are finding amazing ranking jumps when you have content over 3,000 words, about 12 original images (images not found anywhere else online), 1 H1 (not keyword stuffed), 12 sub-headlines (H2), 12 relevant internal links, 6 relevant external links and 1 bullet list. I know it sounds like a lot of work and a Big Mac recipe, but this does work.
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.
