Google Search Quality Rater Guidelines: What You Need To Know

By winniewong on December 21, 2018

Google Search Quality Rater Guidelines feature image

You may have heard about the Google Search Quality Raters Guidelines and let’s be blunt… it’s really thick. 

The document has 168 pages that serve as the extensive guidelines for Search Quality Raters all around the world to evaluate and provide feedback to improve user search experience.  

For SEO’s who have dedicated themselves to keeping up with the Google algorithm update recently, this document serves to reaffirm what you already know, with a few new updates thrown in.

For SEO novices, this serves as a further read up on Google’s preferences and the future of SEO. By following the guidelines, you can know exactly what shall be done to get your website favorable in the eyes of Google.

So let’s break it down. 

There are 9 Key SEO Content Factors in the Google Search Quality Rater Guidelines

1. E-A-T Rating (Expertise, Authoritativeness, Trustworthiness)

EAT Google Search Quality Rater

Websites demonstrating a high level of expertise, authoritativeness, and trustworthiness (E-A-T) is one of the most important characteristics of high-quality content.

Keep in mind that there are high E-A-T pages and websites of all types, even gossip websites, fashion websites, humor websites, forum, and Q&A pages, etc. So, what is EAT?

  • Expertise: The expertise of the creator of the main content
  • Authoritativeness: How much authority the main content creator has
  • Trustworthiness: How trustworthy the main content creator is

Regardless of any algorithm change, in order to build a site for long-term success, you need to understand what and how E-A-T Rating works and ensure you have done all you can to meet the standards.

A) Expertise

In most fields or topics, experts are made through study and certifications. Try to find different ways to show off your expertise on the subject but remember that it varies largely from the purpose of each website.

Having expertise is to show that you know what you’re talking about in your niche. This is especially vital for those in the medical, finance, or legal websites. Your credentials, expertise, and education should be clearly mentioned in your content.

Without a doubt, your products, site functionality, and brand integrity must be perceived highly in order to earn positive press and recommendations from experts in the appropriate industries


You may be a bit confused between the difference of expertise and authoritativeness. Let’s think of it this way:

  • Expertise is based on your familiarity and personal experience with the subject
  • Authoritativeness is based on knowledge and position allowed by other sources

You need to show you are an authority on the topic being discussed. This can be done by drafting content that is clear, concise, and easy to comprehend. Credentials are important, but so do reviews from actual patients and case studies.


The third and last part is trust. Always show users that they can trust the page they are on. If your users are comfortable reading, recommending and sharing the content, then trust is established.

If you’re going to ask for a name, phone number, or email address, make sure the user knows what they are doing and getting out of it.

Don’t seem like a scam to your users nor making it look like a malicious site. Return policies, guarantees, and similar information should be easily accessible. The checkout process shouldn’t be introducing fees or payments they were not expecting or warned about beforehand.

So, ask yourself is your website and content E-A-T-able by Google standards?

2. Main Content & Supplementary Content

i. Main Content (MC)

Main Content (MC) is described by Google as “Any part of the page that directly helps the page achieve its purpose”. Basically, anything that relates to the main purpose of the page – offering news, a useful tool, a blog post – the MC is the content that fulfills this purpose.

It is stated in the guide:

Main Content (MC) Google Search Quality Rater

Webmasters directly control the MC of the page and it can be in the form of text, images, videos, page features or user-generated content like reviews, or articles that they have added to the page.

It’s important to note that the MC should adequately satisfy the user’s query. For a page to be assigned a high page quality rating, there should be a “satisfying amount of high-quality MC”.

To be considered high-quality, your MC should be:

  • Clear and easy to determine
  • Accurate and comprehensive
  • Created with a significant amount of at least one of the following time, effort, expertise, and talent/skill

ii. Supplementary Content (SC)

Supplementary Content (SC) is defined as any content that assists the MC in achieving its purpose. It is controlled by webmasters and is an important part of the user experience. Either it can help a page better achieve its purpose or it can reduce from the overall experience.

Supplementary Content (SC) Google

Webmasters should be asking themselves what types of supplementary content they can include by adding value to users’ experience but it should not interfere with the main content. What are some tools, resources or articles that would be helpful to the reader?

One common type of SC is navigations links that allow users to visit other parts of the website. According to Google, this can include footer info, links to related content, site navigation, features that help shoppers find similar products, etc.

**From our experience writing at SEOPressor, we find it is better to have a satisfactory amount of high-quality main content than creating a high amount of supplementary content. 

However, this can only work if you create high-quality topics that cover broadly and has been optimized with long-tail keywords, like our Big Keyword Research Guide for SEO.

Contrary to popular belief that it is hard to create long-form, in-depth content, we created the guide in just 2 days, using BiQ’s Keyword Intelligence to figure out our target keyword and overall content layout and ideation.  

Then perfecting it using BiQ’s Content Intelligence to make sure each and every paragraph of our content is relevant.

 By doing this, it’ll further improve your content relevant to your target keyword.

3. YMYL Content (Your Money, Your Life Pages)

Google coined the term, Your Money or Your Life Pages (YMYL) to websites if you have the potential to negatively impact users. Held to a much higher standard than a regular website, YMYL websites offer content that may affect a user’s physical and mental health or their financial well-being.

Since the update, many business types fall into the YMYL category and hence the need to maintain high-quality content. Here are some of the businesses affected:

YMYL Google

If your website belongs to one of the categories as mentioned above and if you fail to deliver high-quality information, then Google will leave you out of the top spots of SERP.

4. Mobile Optimization

It’s no longer a secret that Google has been constantly dropping hints about how they love mobile-friendly websites. Google notes that people rely on their phones most of the time these days. The task may range from a simple one like asking for the weather, to a complex one like finding restaurants near you.

We live in an era of “now”, where we all want things immediately. This algorithm is supposed to allow us to find the information that we want as easy as possible.

See, Google has dedicated 1/4th of its quality rating document to mobile search. Sites that aren’t mobile-friendly have a 0% chance of ranking well. This is proof of Google’s chase to refine its mobile search algorithm.

Websites that are not mobile-friendly will suffer the consequences of not being able to rank high

The first step for rating page quality on mobile is to understand the needs of mobile users: which is to complete their task quickly and conveniently. These raters are given a list of queries to type (or speak) and then judge the landing page results.

Google has dedicated an entire section of mobile optimization in the guide, which I will sum up in a few bullet points below:

  • Pages need to be optimized to satisfy abbreviated and voice queries
  • Results should satisfy the user’s need for information and supply it quickly
  • Mobile schema markup game has to be top-notch, not forgetting scoring in your metadata
  • Have reviews available and options to further research if your page is for a product
  • Make sure your website is mobile-friendly
  • Make sure your design is web-friendly with icons that are big enough for human fingers to navigate

Great content isn’t enough, so be sure that your entire website is optimized for mobile users. If you haven’t already, this should be crucial enough to tell you that it needs to be a priority.

5. Understanding User Intent

We already know that user intent is critical to SEO. In the guide, Google further subdivides the queries into the following user queries:

Know Query

In order to be considered as this category of a query, the search topic cannot be too complex or have many potential answers. Essentially, the user is searching because they want to know more about something. Many controversial topics are considered the Know Queries because there are two or more widely diverging opinions on the subject that usually cannot be answered in one or two sentences.

  • Example of Know Queries could be:

[Justin Timberlake],
[Shangri-La Hotel],

Another aspect of this query you ought to know is Know Simple Query. It is slightly different than the Know Queries.

As a rule of thumb, it would fit in 1-2 sentences or a shortlist of items. These comprise of questions with a clear answer.

  • Example of Know Simple Queries are:

[Justin Timberlake Age],
[Shangri-La Hotel Rooms],
[Antman Release Date]

This is especially important if you want to get your web page featured in one of Google’s featured snippets which contain most of the necessary information.

Do Query

This is a query made to accomplish a goal or activity which may either be to buy, download, interact with an app on a phone. Users want to do something.

  • Examples of Do Query by Google:
Do Query Google

A special kind of Do query is the Device Action Query. That means to do something on our device such as open an app, send a text, or view a picture.

  • Here are some examples of Device Action queries:
Device Action queries Google
Call, Text, Navigate, Play, Set, etc. are action words

These results are highly personalized to the user as the query usually has a clear action word and intent.

Website Query

Website Query indicates that the user is looking for a specific website or webpage. These can be direct queries with a perfectly formed URL such as:

However, these can also be imperfect URL queries: Queries that look like URL queries, but are not “working URLs”. These URLs do not load if you type or paste them in your browser address bar.

  • [SEOPressor]
  • [Youtube]

Visit-in-Person Query

Visit-in-person Queries are made by users looking for a specific business or organization. These are search terms that suggest users will make a physical visit to a real-world location.

Using Google’s Guidelines, here are some of the examples:

Visit-in-Person Query Google

Because mobile phones are often used for Visit-in-Person queries, make sure to consider visit-in-person intent as a possibility for mobile phone users.

6. High and Low Page Quality Rating

It is not something new that page quality is being emphasized by Google in order to be categorized as a good page or site. In fact, it is widely accepted by the public that having a quality page that delivers true values is the essential element to excel in the SERP ranking competition.

The verdict is, how we view the quality of a page might be different from how Google views it. Here, we are going to reveal the guidelines Google uses to rate the overall quality of a page.

High-Quality Pages

A website shall be created with a true or beneficial purpose to deliver specific value to its visitors. The better the experience and usefulness of a website provided to the visitors, the higher the page quality will be rated.

When we talk about main content quality, high-quality main content must be factually accurate for the topic which is supported by expert consensus. It’s also about the page features and functionality to fulfill the needs of the topic.

Google trusts a site when its users trust it. Having clear and satisfying website information, as well as information of the person who is responsible for the website is crucial. Users feel comfortable and will trust a site when information is visible. The same goes to the website and site owner’s reputation.

Low-Quality Pages

A low quality page might have a true or beneficial purpose, but fails to achieve it within its page. If a page posses the following characteristics, it will be rated as a low quality page by Google:

  1. An inadequate level of E-A-T
  2. The quality of main content is low
  3. Unsatisfying amount of main content to fit the purpose of the page
  4. A bad or irrelevant title of the main content
  5. Having ads or supplementary content that distract the main content
  6. Unsatisfying amount of website information and information of the person responsible for the site
  7. Negative reputation of a website or reputation of site owner

Compare to high-quality pages, it’s much easier to be rated as a low-quality page if any of the above mistakes is being done and practiced.

As discussed previously, lacking E-A-T is killing the quality of a page. In addition to that, the absence of high-quality main content, unsatisfying amount of the main content will also bring your page quality rating down by Google.

Well, Google is aware that many sites are established with a certain degree of monetization and also to serve additional purposes, such as ads and supplementary content. There is no wrong in doing it. But if the ads and supplementary content are being designed in a way that it distracts the users from the main content, then it will affect the quality rating of a page heavily.

In addition to that, having mixed or mildly negative reputation on a website or the creator of the main content will cause the page to be rated as low quality. Unfortunately, many websites have little reputation information. Here’s what you can do, find more relevant reviews and rating to display on your site, a few negative customers reviews are perfectly fine. More details on the next chapter.

Last but not least, a website should have sufficient amount of information about the website as well as the creator of the website. For a personal website, an email address or social media links would be sufficient. A larger website that involves financial transactions would require more information to achieve a higher level of trust, these include customer service information, person-in-charge contact information and more.

7) The Reputation of Website & Content Creator

One of the most significant additions that we can see in the guidelines this year was the creator’s reputation. Instead of just looking at the reputation of the website, the Google raters have to also identify the reputation of the creator of the main content too if applicable.

Research on the Reputation of the Website or Creator of the Main Content
Google Quality Raters’ Guidelines, page 15, section 2.6.1 – Research on the Reputation of the Website or Creator of the Main Content

It is not about how websites or creators describe their expertise and authority but how reputable external sources agree with what the website says.

According to Google, the reputable external sources that provide independent reputation information about the website or creator may include the following:

  • News article
  • Wikipedia articles
  • Blog posts
  • Magazine articles
  • Forum discussions
  • Ratings from independent organizations

*Customers’ reviews can be helpful for assessing the reputation of the business too but the Google raters are advised to try to find as many reviews as possible when interpreting them.*

Reputation is an important factor to be considered when using the High rating and informs the E-A-T of the page. For example, the high rating cannot be used for any websites that has a convincing negative reputation.

When you have only one creator for the entire website, creating a short bio and then a link to a full author page that includes information such as their credentials or experience will be an added advantage.

But in the cases where you have more than one creators, it will cause some challenges to show the expertise for each one of them.

8) Needs Met Rating Guidelines

In the Needs Met Rating Guideline section, the Google raters were asked to evaluate how helpful and satisfying the result is for mobile users.

The rating consists of five levels, from “Fully Meets” all the way down to “Fails to Meet”:

Rating Using the Needs Met Scale
From The Google Search Quality Rater Guidelines, page 84, section 13.0 – Rating Using the Needs Met Scale

This rating helps Google to understand how search queries are related to user intent, and how helpful is the search results to them.

For example, if there are a lot of low-quality pages that ‘Fails to Meet’ users need showing up for certain query, Google obviously needs to work on delivering better and more relevant results for that particular query.

As website owners, it is important to make sure that your site is able to answer the searches that the searchers made and is relevant and useful to them. Getting a large amount of traffic but a high bounce rate can be one of the signals that you need to look back at your content.

To achieve the highest level of “Fully Meets”, the following must be met:

  • The query and users need must be specific, clear, and unambiguous
  • The result must be fully satisfying for mobile users, requiring minimal effort for users to immediately get or use what they are looking for
  • All or almost all users would be completely satisfied by the result — users issuing that query would not need additional results to fully satisfy the user intent

Let’s imagine this situation, a high-quality page with detailed information about acoustic guitars is useless to you if you actually want information about violins. If you searched for “violin” but the search results are showing pages about acoustic guitars, your search needs is definitely unfulfilled.

9) Overall Page Quality Rating

Overall Page Quality Rating Factors Google

The following are the main factors that are being considered when deciding the overall Page Quality rating:

  • The Purpose of the Page
  • Expertise, Authoritativeness, Trustworthiness
  • Main Content Quality and Amount
  • Website Information/information about who is responsible for the main content
  • Website Reputation/reputation about who is responsible for the main content

When creating the next content, always ask yourself ‘How can my readers benefit from this post’. Because pages that don’t serve any beneficial purpose will ultimately receive the lowest rating and you surely don’t want that to happen.

Once again, Google’s quality ratings will not impact your site’s ranking directly in the search results. But it is always worth taking note that Google does use these ratings to ensure searchers get the most relevant and useful search results.

And that’s it! Hope that’s not a lot to digest? I’m looking forward to hearing your thoughts in the comment section below.

The very first time Google released its Quality Rater Guidelines was in 2015. Quite recently in 2018, they have done a major core update to the guide.

So here we will list down what has changed, and important tips for you to take away from the guide to incorporate into your own sites.

2019 Search Quality Update 1:

Google updated its Search Quality Rater Guidelines on May 16, following its last update in July 2018.

What’s new?
This time, the updates add two pages covering guidelines on content expertise and interstitial pages while lumping E-A-T in with page quality. These revisions, however, do not reflect any great alterations on how quality raters evaluate websites.

2019 Search Quality Update 2:

In July 2019, the Google Search Quality Rater Guidelines have been redirected to a new URL. Click here for the new URL.

It is important to note that it’s different from the Google’s search ranking algorithm which focuses more on the mechanics of getting your website on the first page of SERP (keywords, headlines, backlinks, etc).

Also always be reminded that these quality raters cannot impact your site directly in how it ranks in the search results. But Google surely uses them to ensure the best search results are shown with the highest quality sites ranking first.

To conclude, here’s an overview of the 9 important takeaways summed up in the Google Search Quality Rater Guidelines: 

  • EAT (Expertise, Authoritativeness, Trustworthiness)
  • Main Content & Supplementary Content
  • YMYL Content (Your Money, Your Life Pages)
  • Mobile Optimization
  • Understanding User Intent
  • High and Low Page Quality Rating
  • The Reputation of Website & Content Creator
  • Needs Met Rating Guidelines
  • Overall Page Quality Rating
