Do Google Quality Raters Affect Your Rankings?

This misunderstanding causes a surprising amount of wasted worry. Site owners hear that humans grade websites and assume one of them graded theirs badly.

The reality is less personal and more useful. Raters do not judge your site. They judge Google.

Who the raters are

• Around 16,000 people, according to Google’s own overview of the programme.
• Contractors employed through outside vendors, not Google staff.
• Spread across many regions and languages, so results can be judged by people who live where the searches happen.
• Trained and tested on a long public document called the Search Quality Rater Guidelines.

What they actually do

Raters are given searches and asked how well the results serve the person searching. Often they compare two versions of a results page side by side: the current one and one produced by a proposed change.

Their combined judgements tell Google whether a change makes results better or worse. Ratings are one input among several, alongside live experiments with real users, before Google decides to launch anything.

So the effect on your site is indirect. Raters help shape systems that later rank every site. They never set the position of yours.

What they cannot do

• Change your rankings. Google states that their ratings do not directly influence ranking.
• Apply a penalty. Raters have no access to ranking systems and no way to demote anything.
• Act on a complaint about you. Spam reports go to Google’s spam teams, not to raters.

Raters and manual reviewers are different people

This is the distinction most people miss.

	Quality raters	Manual reviewers
Who	External contractors	Google’s internal spam teams
What they look at	Sample search results	Specific sites and patterns
Can they affect your site?	Not directly	Yes, through a manual action
Will you know?	No, and it does not matter	Yes, a message in Search Console

If a human has acted against your site, the Manual Actions report says so. If it is empty, no person demoted you. How a manual review works is covered in can a competitor report my site to Google.

Why the guidelines still matter to you

The guidelines describe the target Google’s automated systems are tuned toward. That makes them the clearest public description of what Google considers a good page.

• Experience, expertise, authoritativeness and trust, with trust weighted most heavily.
• A higher standard for YMYL topics, where bad information could harm someone’s health, money or safety.
• Reputation research beyond your own site. Raters are told to look at what others say about you, not just what you say about yourself.
• Who is responsible for the site, and whether that is clear to a visitor.

Google’s October 2026 update to its guidance on AI content drew directly on the rater guidelines, which shows how closely the two are connected. Turning the guidelines into a self-assessment is covered in the E-E-A-T scoring rubric.

How to use them

1. Search your own brand the way a rater would, on review sites and forums. Note what a stranger would conclude.
2. Check your About and author pages answer who runs the site and why they are qualified.
3. Read your main pages as a sceptical searcher. Would you trust this answer with your money or health?
4. Fix what a rater would flag, knowing the systems are tuned to flag it too.

Four myths worth dropping

• Raters can see your analytics or Search Console. They cannot. They work from search results and public pages, like any visitor.
• A rater visit means you are in trouble. Raters judge broad samples of searches. A visit says nothing about your standing.
• Following the guidelines guarantees rankings. They describe a target, not a checklist that an algorithm scores line by line.
• Raters mark pages down for using AI. The guidelines say the use of generative AI tools alone does not decide a rating. Effort, originality and accuracy do.

How the guidelines have changed

Google revises the guidelines every year or two, and each revision is worth reading for what it signals.

• November 2023: simpler rating scales, and more guidance on forums and newer formats such as short video.
• January 2025: guidance on content made with generative AI and on several spam patterns.
• October 2026: Google drew on the guidelines when it updated its own advice on AI content.

The pattern is consistent. What appears in the rater guidelines tends to show up later in Google’s public advice to site owners, which makes them an early signal worth watching.

This is not your cause if

• You think a rater visited and marked you down. Their ratings do not move individual sites.
• Your drop matches a core update. That is an automated reassessment, covered in core update vs spam update.
• Your Manual Actions report is empty. No person took action against your site.
