What are the Quality Rater Guidelines?
Google hires “quality raters”, people who visit websites and evaluate their quality. Their feedback doesn’t directly impact your site; it goes to engineers who update the Google algorithm in an effort to display great websites to their users. The guidelines give us great insight as to what Google considers a quality web page.
What’s in the 2018 Quality Rater Guidelines?
If you’re familiar with last year’s QRG, you can head over to this article to see what’s new. As of 2018, Google is working towards identifying the highest quality YMYL sites, and focusing on quality.
YMYL is short for Your Money or Your Life. In Google’s own words, YMYL pages are pages which “could potentially impact the future happiness, health, financial stability, or safety of users.” YMYL pages include but are not limited to shopping or financial transaction websites, financial information pages, medical information pages, legal information pages, news articles and much more. Eg: Was this medical content written by a doctor? Is this content true?
As for quality, I cover much of that in the August 2018 Google Broad Core Algorithm Change article. If you weren’t aware, there was a very large change to the Google Algorithm around August 1, 2018, shortly after the new QRG was released. By the way, it’s not a coincidence if you ask me.
