Cross-Platform Entity Signals
Session 7.4 · ~5 min read
NAP Is Necessary, Not Sufficient
Session 7.3 covered NAP as the primary reconciliation fingerprint. But Google does not rely on NAP alone. When two sources have identical NAP, Google still checks secondary signals to increase confidence. When NAP has minor variations, strong secondary signals can compensate and still allow successful reconciliation.
These secondary signals are cross-platform entity attributes: logo, business description, associated people, industry category, founding date, and website URL. Together with NAP, they form a multi-dimensional identity that Google can match with high confidence.
NAP gets you in the door for reconciliation. Cross-platform signals confirm you belong there and increase Google's confidence score for the match.
The Six Cross-Platform Signals
Beyond NAP, six categories of signals contribute to cross-platform reconciliation.
| Signal Category | What Google Checks | Where It Appears |
|---|---|---|
| Logo / Brand Image | Visual similarity across platforms (Google Vision AI) | Website, GBP, social profiles, directories |
| Business Description | Semantic similarity of entity descriptions | Schema.org description, GBP description, LinkedIn about, social bios |
| Associated People | Person entities linked to organization | Website team page, LinkedIn employees, GBP owner, schema.org founder |
| Industry / Category | Classification consistency | GBP categories, LinkedIn industry, directory categories, schema.org |
| Founding Date | Temporal consistency | Schema.org foundingDate, LinkedIn, Wikidata, Companies House records |
| Website URL | Canonical URL match (including www, https, trailing slash) | All profiles, all directories, all schema |
Visual Matching: Your Logo Across Platforms
Google's image recognition can match logos across platforms. If the same logo appears on your website, your GBP, your LinkedIn page, and your Facebook page, that is a visual reconciliation signal. Variations in logo (different color versions, outdated logos, cropped versions) weaken this signal.
Best practice: use the exact same logo file dimensions and crop across all platforms. Where platforms require different aspect ratios (square for profile photos, landscape for covers), create purpose-built versions of the same core logo rather than stretching or cropping arbitrarily.
Description Consistency
Your business description does not need to be word-for-word identical everywhere. Different platforms have different character limits and contexts. But the core facts should match: what you do, who you serve, where you operate, and what makes you distinct.
Google uses semantic matching, not exact string matching, for descriptions. A description saying "industrial pump supplier serving Jakarta" on your website and "we supply industrial pumps to businesses in the Jakarta metropolitan area" on LinkedIn will reconcile. But "digital marketing agency" on one platform and "pump supplier" on another creates confusion.
Associated People as Reconciliation Anchors
Person entities connected to your organization serve as additional reconciliation anchors. If your website's schema.org lists "John Smith" as founder, your LinkedIn company page shows "John Smith" as CEO, and your GBP is managed by "John Smith," Google has three independent confirmations that the same person is associated with the same organization.
This is especially powerful when the Person entity is itself well-established in the Knowledge Graph. A recognized founder or key executive acts as a bridge between your various platform presences.
The Consistency Matrix
A practical tool for managing cross-platform signals is the consistency matrix: a table with platforms as columns and signals as rows.
| Signal | Website | GBP | Wikidata | ||
|---|---|---|---|---|---|
| Company name | ✓ | ✓ | ✓ | ✗ | ✓ |
| Logo | ✓ | ✓ | ✓ | ✓ | N/A |
| Description | ✓ | ✓ | ✗ | ✗ | ✓ |
| Category/Industry | ✓ | ✓ | ✓ | ✓ | ✓ |
| Founding date | ✓ | ✓ | ✗ | N/A | ✓ |
| Website URL | N/A | ✓ | ✓ | ✗ | ✓ |
Every ✗ in this matrix is a reconciliation risk. The goal is all ✓ marks (or N/A where the platform does not support that field).
Build a consistency matrix for your entity. Every checkmark strengthens reconciliation. Every failure mark is a signal Google may misinterpret or discard.

Assignment
Build your own consistency matrix. Create a spreadsheet with your platforms as columns (website, GBP, LinkedIn, Facebook, Instagram, Wikidata, top 3 directories) and signals as rows (company name, logo, description, category, founding date, website URL, phone, address). Mark each cell as consistent, inconsistent, or not applicable. Fix every inconsistency you find, starting with the highest-traffic platforms.
