On-site trust signals: what Google's quality raters look for
Complete and accurate business information
A detailed About page with the business's history, team, and mission. A real contact address and phone number. A privacy policy and terms of service. These are the basic legitimacy signals that Google's quality raters check first — their absence is an immediate trust deficit.
Transparent authorship
Every piece of content should have a named author with a verifiable bio. Anonymous content is a trust signal failure — it prevents Google from assessing the author's credentials and prevents readers from verifying who is giving them advice.
Accurate and up-to-date content
Content that contains factual errors, outdated statistics, or broken links signals low quality. Google's systems detect content freshness through last-modified dates and content change frequency. Articles that have not been updated in two or more years on fast-moving topics are a trust risk.
HTTPS
All pages should be served over HTTPS. HTTP sites are flagged as 'Not Secure' in Chrome, which damages user trust and increases bounce rates. HTTPS is a confirmed (minor) Google ranking signal and a basic security requirement.
No deceptive patterns
Clickbait headlines that do not match content, hidden fees, fake urgency, or misleading claims are Trustworthiness failures that Google's quality raters are specifically trained to identify. These patterns damage E-E-A-T regardless of the quality of the underlying content.
Organization schema
Organization schema with address, contactPoint, sameAs (linking to Google Business Profile, Companies House, LinkedIn), and logo makes your business's legitimacy machine-readable for Google. It connects your on-site identity with your verified external profiles.
Off-site trust signals: reputation beyond your own site
Google's quality assessment of your site is not limited to what is on your site. It includes your site's reputation across the web — what other sources say about you, whether your business information is consistent across platforms, and whether authoritative sources in your industry reference your work.
Consistent NAP across all platforms
Your business Name, Address, and Phone number must be identical across your website, Google Business Profile, Companies House, industry directories, and any other platform where your business is listed. Inconsistencies are a trust signal failure that affects both local SEO and E-E-A-T assessment.
Google Business Profile reviews
Consistent positive reviews on Google Business Profile are a strong Trustworthiness signal for local businesses. They also directly influence local SEO rankings. Responding to all reviews — positive and negative — demonstrates active business management and adds to the trust signal.
Third-party review platforms
Trustpilot, Clutch, or industry-specific review platforms provide independent verification of your business's quality. These are particularly important for professional services businesses where Google Business Profile reviews may be limited.
Editorial mentions and backlinks
References to your business in trade publications, industry blogs, or news sources — particularly those that include your business name, URL, and a description of your work — are strong off-site trust signals. These are the Authoritativeness signals that also reinforce Trustworthiness.
From our work
A recurring finding in E-E-A-T audits for professional services businesses: the About page is either absent, minimal (three sentences and a stock photo), or focused on the business's history rather than its credentials. Google's quality raters are specifically instructed to check the About page for evidence of the business's expertise and legitimacy. An About page that clearly states the practitioner's qualifications, years of experience, specific methodology, and verifiable professional affiliations — with Organization schema and sameAs links — consistently improves the site's overall E-E-A-T assessment. It is one of the lowest-cost, highest-impact trust signal improvements available.
Frequently asked questions
What are trust signals in SEO?
Trust signals are on-site and off-site indicators that a website is legitimate, accurate, and safe. In Google's E-E-A-T framework, Trustworthiness is the most important component. Trust signals include: complete business information, accurate content, HTTPS, positive reviews, editorial backlinks, and transparent authorship.
Does HTTPS affect SEO?
Yes. HTTPS is a confirmed Google ranking signal, though a minor one. More importantly, HTTP sites are flagged as 'Not Secure' in Chrome, which damages user trust and increases bounce rates — an indirect SEO impact.
How do reviews affect SEO trust signals?
Reviews affect SEO trust signals in two ways: directly, through Review schema that can produce star ratings in search results; and indirectly, through Google Business Profile reviews that influence local SEO rankings and the site's overall reputation signal.
