The search engines that index and rank webpages are designed to figure out the value of your website, whether or not you do anything about it. While the process of SEO evolved to help you get the most out of that “figuring” as possible, search algorithms, by default, will seek out cues from specific data points that you probably have fairly well covered. Don’t get us wrong, we’ve seen these things get screwed up, but it’s usually because of a decision to boost SEO before taking the time to understand what’s already working.
