Search for "Google ranking factors" and you will find lists claiming 200 signals, complete with weights and percentages. None of those lists come from Google. Google has never published a full list of its signals, let alone how much each one counts, and many popular "factors" are guesses, correlations or myths repeated until they sound official.
What Google has done is document a lot: the named ranking systems it uses, what it means by relevance and quality, which page experience signals its systems use, and a long list of things that do not matter. That is enough to build a strategy on solid ground rather than rumours.
This guide separates the evidence into three groups: factors Google has confirmed, factors that are widely believed but unconfirmed or speculative, and things Google has said are not ranking factors. It finishes with how to prioritise your SEO work in 2026 based on what we actually know.
Key Takeaways
- Google uses many automated ranking systems and signals; it does not publish a complete list or any weightings.
- Confirmed factors include relevance to the query (including keywords), links (PageRank), content quality and helpfulness, freshness for some queries, page experience signals such as Core Web Vitals, HTTPS, mobile usability and user context like location.
- Correlation studies and leaks suggest other influences, but treat them as speculative until Google confirms them.
- Google has said several popular "factors" do not matter: meta keywords, word count by itself, heading order and keywords in domain names.
- Relevance and helpful content come first. Technical signals rarely outrank a page that answers the query better.
How Google Describes Ranking
Google's How Search Works site explains ranking in five broad areas: the meaning of the query, the relevance of content, the quality of content, the usability of pages and the context of the searcher. Its developer documentation adds a guide to named ranking systems, such as BERT, RankBrain, neural matching, PageRank, freshness, reviews and spam detection systems.
“The most basic signal that information is relevant is when content contains the same keywords as your search query.”

Two points from that documentation are worth remembering. First, systems work mainly at the page level, though site-wide signals also inform how pages are understood. Second, no single signal decides the outcome; many signals are combined. That is why chasing one metric rarely changes rankings on its own.
Confirmed Ranking Factors
These are factors Google has stated publicly, in its documentation or official announcements, that its systems use.
| Factor | What Google has said | What to do |
|---|---|---|
| Relevance and keywords | Matching words between query and page is the most basic relevance signal; systems also understand synonyms and concepts | Match search intent and use your audience's vocabulary |
| Content quality and helpfulness | Core systems aim to reward helpful, reliable, people-first content; helpful content signals became part of core ranking in March 2024 | Follow Google's helpful content guidelines |
| Links and PageRank | Link analysis systems, including PageRank, help understand what pages are about and which may be most helpful | Earn high-quality backlinks; build sensible internal links |
| Freshness | Freshness systems show fresher content for queries where it is expected | Update time-sensitive content properly |
| Original content | Original content systems help show original reporting ahead of those who only cite it | Publish first-hand data and research |
| Reviews quality | The reviews system rewards high-quality reviews with insightful analysis and original research | Show hands-on testing and evidence |
| Page experience and Core Web Vitals | Core Web Vitals are used by ranking systems, but there is no single page experience signal | Meet good Core Web Vitals thresholds |
| HTTPS, mobile usability, no intrusive interstitials | Listed by Google as aspects of page experience that align with what its systems reward | Use HTTPS, responsive design and restrained pop-ups |
| Spam signals | Spam detection systems, including SpamBrain, demote or remove content that violates spam policies | Follow Google's spam policies |
| Context (location, language, settings) | Location, past Search history and settings help personalise results | Optimise local signals and language targeting |
| Site diversity and deduplication | Usually no more than two results from the same site in top results; near-duplicates are filtered | Avoid near-duplicate pages chasing one query |
“Core Web Vitals are used by our ranking systems.”

Notice how Google qualifies technical signals. The same page experience documentation says Google always seeks to show the most relevant content, even if the page experience is sub-par. Speed and stability help, but they are rarely a reason a weak page outranks a strong one.
Unconfirmed and Speculative Factors
Many factors discussed in the SEO industry come from correlation studies, patents, experiments or third-party metrics. Some may reflect real signals; others may only correlate with success. Treat them as hypotheses.
| Claimed factor | Status | Sensible view |
|---|---|---|
| Click-through rate and user engagement | Debated; Google has not confirmed CTR as a direct ranking factor | Improve titles and content for users anyway |
| Domain authority scores | Third-party metrics, not Google signals | Useful for comparison only; see domain authority explained |
| Brand mentions without links | Unconfirmed as a direct factor | Brand building helps in many indirect ways |
| E-E-A-T as a score | Google says E-E-A-T itself is not a specific ranking factor; systems use a mix of signals that align with it | Show real expertise and clear authorship |
| Content length | Google says length alone does not matter | Cover the topic fully, no padding |
| Domain age | No confirmation that age itself helps | Focus on history and reputation, not age |
| Author reputation | Google asks creators to show who wrote content; direct use as a signal not confirmed | Build credible author pages |
Be especially careful with any list that assigns percentages to factors. Without access to Google's systems, such numbers are opinions.
Things Google Says Are Not Ranking Factors
- Meta keywords tag: Google Search does not use it.
- Word count alone: Google says the length of content alone does not matter for ranking.
- Heading order: from a Search perspective it does not matter if headings are used out of order (although order matters for accessibility).
- Keywords in domain names: they have hardly any effect beyond breadcrumbs, and the exact match domain system limits credit for query-matching domains.
- Google Ads spend: Google has long stated that advertising does not influence organic rankings.

How to Prioritise Ranking Factors: A Step-by-Step Approach
- Fix eligibility. Make sure important pages can be crawled and indexed, and are not blocked by robots.txt or noindex.
- Nail relevance. One clear topic per page, matched to search intent and phrased in your audience's words.
- Raise quality. Add first-hand experience, evidence, clear authorship and better answers than the current results.
- Strengthen internal links. Connect related pages so link signals and context flow through the site.
- Earn external links and mentions. Create assets worth citing and promote them.
- Clean up technical friction. Core Web Vitals, HTTPS, mobile layout, intrusive interstitials.
- Stay within the rules. Avoid anything that breaches spam policies; a demotion can undo all of the above.
- Monitor updates. Watch the Search Status Dashboard and read our guide to Google core updates before reacting to volatility.
Local and Specialised Factors
Some searches use additional systems. Local results lean on relevance, distance and prominence through Google Business Profile data; read local SEO ranking factors for that list. News queries can trigger local news and freshness systems, and health or finance topics are held to higher standards of reliability because Google's reliable information systems prioritise authoritative sources.
Common Mistakes
- Trusting "200 factors" lists as fact. They mix confirmed signals with speculation.
- Optimising one signal in isolation. Perfect Core Web Vitals will not rescue thin or off-intent content.
- Confusing correlation with causation. Pages with many backlinks also tend to be better resourced in every other way.
- Treating third-party scores as Google metrics. Authority scores are estimates from tool vendors.
- Chasing word counts. Length is not a factor by itself.
- Ignoring the spam policies. Manipulative tactics can cause demotions that outweigh any gains.

Frequently Asked Questions
How many ranking factors does Google use?
Google says it uses many factors and signals but has never published a number or a complete list. Figures like "200 factors" are not official.
Are backlinks still a ranking factor?
Yes. Google documents link analysis systems, including PageRank, as part of how it understands pages and their importance.
Is E-E-A-T a ranking factor?
Google says E-E-A-T itself is not a specific ranking factor, but its systems use a mix of signals that align with experience, expertise, authoritativeness and trust.
Do Core Web Vitals affect rankings?
Yes, Google confirms its ranking systems use Core Web Vitals, but relevance usually matters more.
Is click-through rate a ranking factor?
Google has not confirmed CTR as a direct ranking factor. Treat it as speculative and improve titles for users regardless.
Conclusion
The honest answer to "what are Google's ranking factors?" is that we know the broad categories, several confirmed systems and a handful of confirmed signals, but not the weights. That is enough to act on: match intent, create genuinely helpful content, earn links, keep the site technically sound and stay inside the rules.
