What Are Google's Search Quality Rater Guidelines? Do Raters Affect Rankings?

Google's Search Quality Rater Guidelines are the handbook its human raters use to judge search results, and the ratings they give don't directly change any site's rankings. Google uses them to check whether its ranking systems are working and to test changes before launch. That makes the guidelines a clear, public description of what Google means by a high-quality page, and a useful self-check for your own site. They aren't a list of ranking factors.

What are Google's Search Quality Rater Guidelines?

The Search Quality Rater Guidelines are a public document of well over 100 pages, written for the external raters who evaluate Google Search. The current version is dated 11 September 2025. Raters are asked to represent people in their own language and location, and to base ratings on the guidelines rather than their personal opinions.

The document has three main parts:

1. Page Quality rating. How well a page achieves its purpose, including who is responsible for it and their reputation.
2. Understanding search user needs. How to read a query and work out what the person is likely looking for, which is the same idea as search intent.
3. Needs Met rating. How well a result answers a specific search.

Do quality raters affect your rankings?

No, not directly. The guidelines say so in their opening section: no single rating can directly change how a page or site appears in Google Search, or move results up or down. Google adds that using human ratings to position results wouldn't be feasible, because people could never rate every page on the web.

Google's guide to creating helpful content puts it more plainly. Raters "have no control over how pages rank" and rater data "is not used directly in our ranking algorithms". Google compares the ratings to feedback cards a restaurant collects from diners. They tell Google whether its systems seem to be working.

The indirect effect is real, though. Raters help Google decide which algorithm changes launch, and those changes then apply to every site. So if your pages look Low quality by the standards in the guidelines, you're exposed when a core algorithm update rolls out, even though no rater has ever seen your site.

How does Google use the ratings?

Google's page on how it tests changes to Search describes two jobs for raters. They rate the quality of results on an ongoing basis, which Google uses to benchmark Search around the world. They also take part in side-by-side experiments, where they see one set of results with a proposed change and one without, and say which they prefer and why.

Engineers and analysts then review the experiment data and decide whether a change launches. If Google can't show that a change makes results better for people, it doesn't launch it. That's why the guidelines are worth reading. They describe what the people grading Google's changes are told to reward.

What do raters actually rate?

Raters give two main ratings. Page Quality looks at the page on its own, without the search. Needs Met looks at the page as an answer to a particular query, so the same page can rate High for quality but Fails to Meet for a search it doesn't answer.

For Page Quality, the guidelines tell raters to consider:

1. The purpose of the page. Pages with a harmful or deceptive purpose are rated Lowest.
2. How much the topic is YMYL. Higher standards apply to topics that could affect someone's health, money or safety.
3. The quality of the main content. Effort, originality, talent or skill, and how well it achieves its purpose.
4. Reputation. What others say about the website and the people who create its content.
5. E-E-A-T. The experience, expertise, authoritativeness and trust behind the content.

The guidelines also ask raters to find who is responsible for the website and who created the content, and to look for About, contact and customer service information. If you can't tell who runs a site, a rater can't either.

What is E-E-A-T, and why does Trust matter most?

E-E-A-T stands for experience, expertise, authoritativeness and trustworthiness. Google's Search Central blog explained that the extra E for Experience was added in December 2022 to recognise content made by someone with first-hand experience, such as actually using a product or visiting a place.

The guidelines call Trust the most important member of the family, because an untrustworthy page has low E-E-A-T however experienced or expert it seems. Their example is a financial scam: it's untrustworthy even when the person behind it is an expert scammer.

Google is careful to say that E-E-A-T isn't a specific ranking factor. Its systems use a mix of signals that can identify content with good E-E-A-T, and they give those signals even more weight on "Your Money or Your Life" topics. The Academy lesson on helpful content and E-E-A-T covers how to show it on a page.

What gets a page rated Lowest?

The Lowest rating is reserved for pages that are harmful, deceptive, untrustworthy or spammy. The guidelines line up closely with Google's spam policies, so a page that would trip a spam policy will also rate badly with raters. Our guide to Google's spam policies walks through each one, and a confirmed breach can bring a manual action.

What should a business take from the guidelines?

Use them as a self-check, not a ranking manual. Google's own core updates guidance points site owners towards assessing their content rather than chasing fixes, and the guidelines show what that assessment looks like from the outside. Our helpful content self-assessment turns Google's questions into a working list, and our guide to Google core updates explains what to do after traffic drops.

Reputation is the part businesses most often skip. Raters are told to look for what others say about you, so independent reviews matter beyond local search. Our guide to getting more Google reviews covers that side. Google's ranking systems guide also describes a reviews system that rewards insightful analysis and original research from experts or enthusiasts who know the topic well.

How should you judge an agency that talks about E-E-A-T?

Be wary of any agency that promises to "add E-E-A-T" or calls rater scores a ranking factor. Google says neither is how ranking works. A credible proposal talks about real improvements: clearer authorship, stronger helpful content, first-hand experience, and reputation building. The Academy lesson on evaluating proposals and red flags covers what else to check.

Quality rater guidelines checklist

• Every important page has a clear purpose for a real reader.
• Your site shows who owns it, with an About page and real contact details.
• Articles and advice pages name the person or team responsible.
• Content shows first-hand experience where readers would expect it.
• YMYL pages on health, money or legal topics are written or checked by qualified people.
• You have independent reputation signals, such as reviews and press coverage.
• No pages are copied or reworded from elsewhere with nothing added.
• Your agency talks about improving content and reputation, not "adding E-E-A-T".

Bottom line

The quality rater guidelines don't decide your rankings, but they describe the results Google is trying to reward. Raters grade Google's changes, and the changes that pass apply to every site. Read the guidelines as a description of a trustworthy page, check your own site against them, and put your effort into real experience, clear ownership and a good reputation.
