A new case study published by Search Engine Journal examines how entity linking — connecting a business to recognized entities across the web — can support visibility in local search results.

The case study format matters here. Rather than offering general theory, the piece walks through a practical implementation of entity-based optimization for a local business, testing whether strengthening the connections between a brand, its locations, and authoritative third-party references produces measurable movement in local rankings and presence.

What is entity linking in a local context?

Entity linking refers to the process of associating a business — its name, its people, its locations, its services — with unambiguous, machine-readable identities that search engines already recognize. For local businesses, this typically means aligning signals across:

• The company's own site and its structured data
• Google Business Profile information
• Third-party mentions, citations, and profiles
• Knowledge graph and Wikidata-style references

Search engines increasingly evaluate local relevance not only through traditional ranking factors but through how confidently they can resolve a business as a distinct, verified entity. The case study explores how deliberate entity linking supports that resolution.

How does the case study frame the impact?

The published piece presents the work as a case study — that is, the publisher's framing rests on a specific implementation rather than a broad industry dataset. Readers should treat the findings as evidence from one documented scenario, not as a controlled study with statistical power.

Search Engine Journal's decision to publish the material as a case study signals that the techniques described are practical and replicable, but the outcomes described are specific to the business examined. Google has not made any official statement about entity linking as a confirmed ranking mechanism, so any ranking effect described in the piece should be understood as practitioner observation rather than an engine-confirmed factor.

Why does this matter for local SEO now?

Local search results have absorbed repeated changes over the past two years, including tighter integration of business information into AI-generated summaries and continued evolution of Google Business Profile features. In that environment, businesses that search engines can confidently identify — with consistent, interlinked references across the web — are better positioned to appear in enhanced surfaces, from map packs to AI Overviews that cite local providers.

Entity-level consistency also reduces ambiguity. When two similarly named businesses operate in the same market, strong entity linking helps the search engine attribute reviews, locations, and mentions to the correct one — a failure point that can quietly erode local visibility.

What should practitioners take from it?

The actionable takeaway from the case study is that entity linking is an optimization surface local businesses can work on directly: auditing how the business is described across its own site, its profiles, and third-party references, and tightening those connections so search engines resolve the brand cleanly.

For multi-location businesses, franchises, and brands with rebrands or legacy citations, the exercise is particularly relevant, because fragmented identity signals tend to accumulate exactly in those scenarios.

What to watch next

Monitor whether subsequent case studies or tool-provider data quantify the ranking effect of entity linking across a larger sample of local businesses — and whether Google ever acknowledges entity resolution as a formal local ranking input.
