The 10 Google Patents Behind Local Rankings
Google can hide its algorithm, but it can't hide a patent. Here are the ten granted filings that describe how local businesses get ranked — and what each one rewards.

Most of what gets sold as "local SEO" is opinion. Patents are different. They're public filings, granted by the U.S. Patent and Trademark Office, and they describe the inputs a system is designed to consume.
Google can hide the algorithm. It can't hide a patent.
When we built Rank Local, we pulled every granted Google filing we could find that covers local ranking, listed the signals each one names, and built one automation per signal. Here are the ten that matter most.
1. Location Prominence Score — US8046371B2
How well known and active a business is. Fresh content, mentions and activity across the places Google looks all feed prominence. A business that posts after every job looks very different from one that posted once in 2019.
2. User Interaction Signals — US8312010B1
How real people search for, click on and engage with a listing. Interaction that Google can observe — a search, then a click on the result — carries weight that a direct link click never does.
3. Entity Attribute Understanding — US11762933B2
How Google works out what a business is, what it does and where. Consistent descriptions of services and locations make the entity clearer.
4. Multi-Faceted Review Analysis — US8046371B2
Not just star ratings: the volume, recency and content of reviews.
5. Dynamic Context & Intent — US9460401B2
Matching a business to what someone means right now, where they are.
6. Content Quality & Topical Authority — US9195944B1
Depth and consistency of content that proves expertise in a service.
7. Link & Mention Velocity — US8407231B2
The rate at which new links and mentions appear. Steady, ongoing growth reads differently from a one-time burst.
8. Image Semantic Analysis — US20230409653
What a business's photos actually show, and how that connects to its services.
9. Geographic Signal Integrity — US8156099B2
Consistent, verifiable location data that shows where a business really works.
10. Machine Learning & Predictive Ranking — US9460401B2
Models that weigh all of the above together.
What this means for agencies
Read side by side, the filings point at one pattern: ongoing, real-world activity, documented consistently. That's hard to fake and expensive to produce by hand — which is exactly why we tied every signal to a single trigger: the completed job.
