Instead, in this instance, we started at wireframe stage, plopping in keywords and meta tags. Of course, the site really needed those things, and although it launched technically “optimized”, it wasn’t enough to provide a better product than our top competitor(s). A product that people want to visit, revisit, email to friends, share on social networks, and link to more than our competitors. It wasn’t even enough to move up in the rankings.

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.
This philosophy is beautiful in its simplicity, and it serves to correct the “more, more, more” mentality of link building. We only want links from relevant sources. Often, this means that in order to scale our link-building efforts beyond the obvious tactics, we need to create something that deserves links. You have links where it makes sense for you to have links. Simple.
Users will occasionally come to a page that doesn't exist on your site, either by following a broken link or typing in the wrong URL. Having a custom 404 page30 that kindly guides users back to a working page on your site can greatly improve a user's experience. Your 404 page should probably have a link back to your root page and could also provide links to popular or related content on your site. You can use Google Search Console to find the sources of URLs causing "not found" errors31.
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 🙁
