SEOs were first introduced to the concept of Your Money or Your Life pages last year in a leaked copy of the guidelines. These are the types of pages that Google holds to the highest standards because they're the types of pages that can greatly impact a person’s life. While anyone can make a webpage about a medical condition or offer advice about things such as retirement planning or child support, Google wants to ensure that these types of pages that impact a searcher’s money or life are as high-quality as possible. In other words, if low-quality pages in these areas could “potentially negatively impact users’ happiness, health, or wealth,” Google does not want those pages to rank well. If you have any web pages or websites that deal in these market areas, Google will hold your site to a higher standard than it would a site on a hockey team fan page or a page on rice cooker recipes.
