I read The Art of War in college, written by the Chinese general Sun Tzu (author of the quote above). While his actual existence is debated, his work is often considered as brilliant military strategy and philosophy. Thus, The Art of War is often co-opted into business for obvious reasons. Throughout the book, you'll realize tactics and strategy are not interchangeable terms.
Attempting to replace a dead link with your own is easily and routinely identified as spam by the Wikipedia community, which expects dead links to be replaced to equivalent links at archive.org. Persistent attempts will quickly get your account blocked, and your webiste can be blacklisted (the Wikipedia blacklist is public, and there is evidence that Google uses it to determine rankings), which will have negative SEO consequences.
There were some great tips in this article. I notice that many people make the mistake of making too many distracting images in the header and the sidebar which can quickly turn people off content. I particularly dislike google ads anchored in the centre of a piece of text. I understand that people want to make a revenue for ads but there are right ways and wrong ways of going about this. The writing part of the content is the important part, why would you take a dump on it by pouring a load of conflicting media in the sides?
Write a description that would both inform and interest users if they saw your description meta tag as a snippet in a search result. While there's no minimal or maximal length for the text in a description meta tag, we recommend making sure that it's long enough to be fully shown in Search (note that users may see different sized snippets depending on how and where they search), and contains all the relevant information users would need to determine whether the page will be useful and relevant to them.
Expert roundups have been abused in the Internet Marketing industry, but they are effective for several reasons. First, you don’t have to create any content. The “experts” create all the content. Second, it is ego bait. Meaning, anyone who participated in the roundup will likely share it with their audience. Last, it is a great way to build relationships with influencers.
Lastly, it's important to remember that paralysis by over-thinking is a real issue some struggle with. There's no pill for it (yet). Predicting perfection is a fool's errand. Get as close as you can within a reasonable timeframe, and prepare for future iteration. If you're traveling through your plan and determine a soft spot at any time, simply pivot. It's many hours of upfront work to get your strategy built, but it's not too hard to tweak as you go.
