Wikidata for Local SEO Agencies: April 2026 Data Snapshot

If you run local SEO for clinics, law firms, or real estate brands, this is the plain value:

• Most competitors are not in Wikidata yet.
• If you add a client to Wikidata, they have a better chance to be mentioned by AI assistants.
• This is a service you can package, sell, and report on.

This post uses live data from the Wikidata Query Service, queried on April 23, 2026.

Key numbers (live data, April 23, 2026)

These counts come from our internal coverage queries and are also saved in reports/wikidata-multi-industry-coverage.json.

Why this matters for SEO agencies

Agencies can turn this into a simple offer:

• Step 1: Check whether the client has a usable Wikidata entity.
• Step 2: Publish or improve the entity with core business facts.
• Step 3: Track whether the client starts appearing in AI answers.
• Step 4: Show before/after results in monthly reporting.

The data supports the pitch: there are still very few entities in key local-business categories, so clients can gain early visibility.

Methodology (high-level)

We use a consistent internal ruleset on Wikidata data:

• Count US entities in each segment with an official website field.
• Use one standardized definition per segment (law firms, medical clinics, real estate companies).
• Keep hospitals as a comparison segment to show relative coverage.
• Run the same logic each refresh cycle so changes are comparable over time.

This keeps reporting consistent while avoiding one-off query drift.

Practical takeaways you can use this month

1. Use one sentence in proposals: "If your business is missing from Wikidata, AI assistants are less likely to recommend you."
2. Sell one fixed package: Audit -> publish -> validate -> monthly visibility check.
3. Start with medical clinics: The gap is easiest to explain (44 clinics vs 3,348 hospitals in the US).
4. Repeat on a cadence: Refresh these counts monthly or quarterly and reuse them in sales decks and QBRs.
