Features/commentsIn this column, I put all of my comments, some ”star” features I needed to focus on, and the pros and cons of the competitor. I color-coded the cells so that later I (or anyone viewing the matrix) could easily identify the difference between them. For example, I used light yellow for features, light purple for comments, green for pros and red for cons.

This emphasis on competition is related to the advent of game theory in the mid 20th century around the same time. The problem is that game theory is one mental model of many to help make decisions, not the only one (Ben Thompson from Stratechery has a good post on the Prisoner’s Dilemma that is a fundamental one). Even researchers are starting to point to the fact that there are no perfect solutions (such as a Nash equilibrium) to most situations.

Like most advertising techniques, geo-targeting predates the internet. Local papers, radio and television programs have long been used to reach customers in a particular region with ads. These advertisements were customized for the local audiences where possible, a process that we now call optimization. Digital technology has simply made this practice more widespread. The major innovation that has increased the effectiveness of geo-targeting is the addition of other data points beyond simple location.

When using the Keyword Explorer, Ahrefs will also produce the "parent topic" of the keyword you looked up, as you can see in the screenshot above, underneath the Keyword Difficulty meter. A keyword's parent topic is a broader keyword with higher search volume than your intended keyword, but likely has the same audience and ranking potential -- giving you more a valuable SEO opportunity when optimizing a particular blog post or webpage.
