Knowledge Graph Checker: Check Your Google Visibility, Knowledge Graph ID & Confidence Score

In today’s AI-driven search landscape, ranking on Google is no longer just about keywords and backlinks. Google now understands entities—people, brands, organisations, products, and places—through its Knowledge Graph. If your brand is recognised as an entity, you have a much better chance of appearing in AI-generated answers, Google’s knowledge panels, and voice search results.

This is where a knowledge graph checker becomes essential. It helps you verify whether Google recognises your brand, discover your Knowledge Graph ID (KGID), and analyse your confidence score, which indicates how strongly Google associates your entity with trusted information across the web.

A powerful free tool is available here:

Knowledge Graph Checker by DGTLmart

This guide explains what the Knowledge Graph is, how the checker works, and how you can improve your Google visibility and brand authority.

What Is Google’s Knowledge Graph?

Google’s Knowledge Graph is a massive database of entities and their relationships. It connects information from trusted sources such as:

  • Official websites

  • Wikipedia and Wikidata

  • Google Business Profiles

  • News publications

  • Social media profiles

  • Author pages and citations

When Google is confident about an entity, it may display a Knowledge Panel on the search results page. This panel can include your logo, website, social profiles, founder information, and other key details.

For businesses, appearing in the Knowledge Graph can improve:

  • Brand credibility

  • Click-through rate (CTR)

  • AI search visibility

  • Voice search presence

  • Local SEO performance

Why You Need a Knowledge Graph Checker

A knowledge graph checker allows you to see whether Google has already created an entity for your brand and how strong that entity is.

Key insights you can get

Metric

What it means

Knowledge Graph ID

Unique identifier assigned by Google

Confidence Score

Google’s confidence in the entity match

Entity Type

Business, Person, Organisation, Product, etc.

Connected Sources

Websites and profiles associated with the entity

Visibility Status

Whether the entity is recognised or not

These insights help you identify gaps in your brand’s online presence and build a stronger entity footprint.

How to Use the DGTLmart Knowledge Graph Checker

Using the tool is simple and completely free.

Step-by-step process

  • Visit the knowledge graph checker tool .

  • Enter your brand name, website, or person name.

  • Click Check Visibility.

  • Review your Knowledge Graph ID and confidence score.

  • Analyse the associated entities and sources.

The tool is useful for businesses, personal brands, agencies, authors, and eCommerce stores.

Understanding the Confidence Score

The confidence score is one of the most important metrics in a knowledge graph checker. It represents how certain Google is that the entity it found is actually your brand.

Confidence score ranges

0–30

Weak entity

31–70

Moderate entity

71–100

Strong entity

A low score means Google has limited or inconsistent information about your brand. A high score indicates strong entity recognition and better eligibility for knowledge panels and AI search features.

How to Improve Your Knowledge Graph Visibility

If your score is low, don’t worry. You can strengthen your entity over time with the following strategies.

1. Add schema markup

Use structured data on your website, especially:

  • Organization

  • Person

  • WebSite

  • LocalBusiness

  • Product

  • Article

Schema helps Google understand who you are and how your content is connected.

2. Keep brand information consistent

Ensure the following details are identical across all platforms:

  • Brand name

  • Website URL

  • Logo

  • Address

  • Phone number

  • Social media handles

Inconsistent information can reduce Google’s confidence in your entity.

3. Create author and about pages

A detailed About Us page and Author Bio pages help establish expertise and trust.

Include:

  • Founder information

  • Experience and credentials

  • Social profile links

  • Organisation details

  • Contact information

4. Build authoritative mentions

Get your brand mentioned on:

  • Industry blogs

  • News websites

  • Business directories

  • Podcast interviews

  • Professional associations

These mentions act as entity validation signals.

Knowledge Graph and AI Search

Google’s AI Overviews and answer engines rely heavily on entity understanding. Brands with strong Knowledge Graph signals are more likely to be cited in AI-generated responses.


A knowledge graph checker helps you measure your readiness for:

  • Google AI Overviews

  • ChatGPT search citations

  • Gemini answers

  • Perplexity AI

  • Voice assistants

Entity SEO is becoming the foundation of Generative Engine Optimization (GEO) and AI SEO.

Common Reasons Your Brand Is Not Found

If the checker cannot find your entity, these are the most common causes:

Issue

Solution

New website

Publish more authoritative content

No schema markup

Add structured data

Few backlinks

Build quality backlinks

Inconsistent brand name

Standardise branding everywhere

No external mentions

Earn PR and directory citations

Entity recognition usually improves as your brand gains authority and consistent references across the web.

Best Practices for Long-Term Entity SEO

Follow these best practices to maintain a strong Knowledge Graph presence:

  • Use the same brand name everywhere.

  • Link all social profiles from your website.

  • Publish expert-level content regularly.

  • Use internal linking to connect related topics.

  • Monitor your Knowledge Graph ID periodically.

  • Update schema markup whenever business details change.

  • Track confidence score improvements over time.

Final Thoughts

Google is moving from a keyword-based search engine to an entity-based search engine. If your brand is not recognised as an entity, you may struggle to gain visibility in AI-powered search experiences.

Using a knowledge graph checker is the fastest way to understand your current entity status, find your Knowledge Graph ID, and evaluate your confidence score. With the insights from the DGTLmart tool, you can take actionable steps to improve your brand authority, increase Google visibility, and prepare for the future of AI search.

A strong Knowledge Graph presence today can become your biggest competitive advantage in tomorrow’s AI-driven search ecosystem.
