Cornerstone content is a foundational piece of content on your site. It is usually a long-form, comprehensive guide that covers everything about a core topic in your niche. It serves as the "lighthouse" for your authority.
Document your journey. Authority can be built by being the "reporter" of your niche. Test theories, summarize expert findings, and be transparent about your learning process. This is called "Lead by Example" authority.
Quality over quantity. One deep-dive authority piece per month is better than 10 generic posts. Spend 80% of your time on 20% of your content that truly moves the needle on your credibility.
