By a good margin, keywords falling under the category of health experienced the largest changes in search rankings on the 1st August, the day the update was rolled out.
Your money or your life (YMYL) content
Most of the signs from this update suggest that Google has significantly tweaked the ranking factors for ‘Your Money or Your Life’ (YMYL) content, a concept introduced in Google’s Search Quality Ratings Guidelines for “types of pages which could potentially impact the future happiness, health, financial stability, or safety of users”.
This fits with the ranking shifts within health content, but also the changes in finance rankings which other tools picked up on.
The search quality guidelines suggest that the following types of pages could fall under YMYL:
- Shopping or financial transaction pages
- Information or advice in the following areas: financial, medical or legal
- Information about local/state/national government processes, policies, people, and laws
This type of content is high risk to Google, where serving inaccurate or misinformed content around financial, medical or legal topics could have significant ramifications for a user if they follow the given advice.
Say for example, Google’s algorithm chooses incorrect informational content around prescription drug dosages to display in the top positions, which a user then goes on to trust and base a decision upon, this could obviously have a very bad result for the user and longer term, Google.
Where in contrast, if the algorithm ranks the wrong information for putting up a flat pack TV stand, the impacts are far less significant for the user.
For queries potentially affecting YMYL, it’s even more crucial that Google identifies the source with the most expertise, authority and trust – and ranks them accordingly.
Every niche saw some sort of ranking flux from the update, however it looks like the signals which Google changed in the algorithm were ‘turned up’ even more for YMYL queries.
Expertise, authority & trust (EAT)
Google’s search quality ratings guidelines make constant mention of expertise, authority and trust (EAT) as a signifier of high quality content.
This EAT signal appears to have increased in significance particularly for YMYL queries, but also potentially more generally across the algorithm – a lot of sectors beyond even the widest definitions of your money or your life content have seen large shifts over the last few weeks.
So, what exactly is Google looking for in terms of a websites’ expertise, authority and trust?
Google doesn’t actually define clear examples of EAT, however it does provide examples of signals of the lowest EAT, which in turn tells us a lot about what the search engine is looking for.
Google’s example signals of pages with significantly low EAT:
- The creator of the content does not have adequate expertise in the topic. e.g. a tax form instruction video made by someone with no clear expertise in tax preparation
- The website is not an authoritative source for the topic of the page, e.g. tax information on a cooking website
- The content is generally not trustworthy, e.g. a shopping checkout page that has an insecure connection
Effectively, this suggests that Google is looking for content written by trusted authors in their niche, as well as being on a trustworthy, relevant platform.
Which kind of signals could Google be using to evaluate EAT?
It’s hard to say for definite the exact signals which Google could be looking at to determine EAT, but with all the information that they have available to them you can probably make some suggestions as to the kind of things they’d be looking for.
You’d assume that Google is looking at both on-page and off-page signals to evaluate a writer’s authority, in the same way that this combination of factors is used to assess the majority of other parts in the algorithm:
Off-page - it’s very likely that Google is assessing a writer’s authority by how many times the publisher is cited across different web-pages, as well as how many times they’ve been featured on different domains.
This will probably go beyond links, potentially looking at both author and publisher mentions. With all of the content in the index it’s not unrealistic to suggest they could evaluate this with good accuracy on a massive scale.
On-page - factors evaluating the content on a website will surely also play a part in an algorithms’ measurement of contextual EAT, where clear author profiles and company credentials in a website’s about us page could be good places to show off your EAT.
Interestingly, RankRanger suggest that from their winner & loser analysis, sites which displayed credible author profiles throughout articles, particularly in YMYL verticals, tended to perform well following the update and many sites without authorship profiles lost visibility.
Authorship and building the credibility of both the writers on your website and the site itself seems to be the key to improving your EAT and receiving a positive assessment from this part of the algorithm.
Content intent
Looking at the winners and losers from the latest update, another observation is that websites with the purest intent to inform a user look to have been those that have either remained safe from ranking shifts or seen large increases in visibility.
Commercial websites which host informational content often have split intent, where they’ll be using their articles and guides to support another interest, whether it be to sell something, drive pageviews to serve ads or to support the rankings of another part of their site. This can be seen as impure intent: where they’ll be trying to serve both their own intent and the users.
A good example of a site with obvious split intent is draxe.com, a medical site in the US which sells both recipes and diet plans, as well as providing advert space for other health products:
