What is the Google Possum Update?
The Google Possum Update was a local search algorithm change in September 2016 that made local results more sensitive to the searcher’s exact location and added filters to prevent businesses sharing an address from both appearing in the same local pack.
Named “Possum” by the SEO community (because some listings appeared to “play dead” — disappearing from results), this update dramatically changed local rankings. Results started varying significantly based on where exactly a person searched from. A search from north Dallas produced different local pack results than the same search from south Dallas.
The update also introduced address-based filtering. If two law firms shared an office building, Possum might only show one in the local pack for the same query. This impacted coworking spaces, shared office buildings, and businesses using virtual addresses.
Why Does the Google Possum Update Matter?
Possum fundamentally changed how businesses experience and track local rankings.
- Rankings vary by location — checking your rank from your office gives a different result than what customers across town see
- Suburban businesses gained visibility — searches from suburban areas started favoring nearby suburban businesses over distant downtown competitors
- Shared addresses became a liability — businesses in the same building got filtered against each other for identical queries
- Made geo-grid rank tracking essential — checking rankings from one location became meaningless; you need grid-based tracking
Post-Possum, local SEO tracking requires tools that check rankings from multiple geographic points, not just one.
How the Google Possum Update Works
Location-Based Variation
Before Possum, local results were relatively static across a metro area. After Possum, results change significantly based on the searcher’s exact position. A search from 2 miles east produces different results than from 2 miles west. Google weights distance from the searcher’s precise coordinates, not just the city center.
Address Filtering
When multiple businesses at the same physical address target similar keywords, Possum often filters all but one from the local pack for a given query. This doesn’t affect organic results — only the local pack. Businesses in shared office buildings or co-working spaces are most affected.
Impact on Strategy
Track rankings from multiple locations using geo-grid tools. Focus on building strong prominence signals (reviews, citations, content) to win when distance is equal. If you share an address with a competitor, differentiate through your primary category and services. Publishing consistent content through theStacc builds the authority signals that help you survive Possum filtering.
Google Possum Update Examples
A chiropractor in a medical office building shares the address with a physical therapist. Both target “back pain treatment near me.” After Possum, only the chiropractor appears in the local pack for that query because they have more reviews and a more specific GBP category. The physical therapist’s listing isn’t penalized — it’s just filtered for overlapping queries.
A dentist 5 miles from downtown notices their local pack rankings vary wildly. From their office location: position #1. From the city center: not appearing. Geo-grid tracking reveals they dominate a 4-mile radius around their office but are invisible beyond that. Targeted content for neighborhoods on the edge of their visibility helps expand their local footprint.
Common Mistakes to Avoid
Local SEO mistakes are surprisingly common — even among businesses that invest in marketing.
Inconsistent NAP information. Your business name, address, and phone number listed differently across directories. Google treats inconsistency as a trust signal — a negative one. Audit your citations and fix mismatches before doing anything else.
Ignoring Google reviews. Not asking for reviews, not responding to reviews, or worse — buying fake ones. Reviews are a direct ranking factor in the Local Pack. A steady stream of real reviews from real customers beats everything else.
Generic location pages. Creating 50 city pages with identical content except the city name swapped out. Google recognizes this pattern instantly. Each local landing page needs genuinely unique content.

Frequently Asked Questions
Is the Possum Update still active?
Yes. Possum’s address filtering and location-based variation are permanent features of Google’s local algorithm. Every subsequent update builds on these mechanics.
How do I check my real local rankings after Possum?
Use geo-grid rank tracking tools like Local Falcon, Local Viking, or BrightLocal’s grid tracker. These check your ranking from dozens of points across your service area, giving you an accurate picture of your local visibility.
Can I recover a filtered listing?
If your listing is being filtered due to a shared address, differentiate your GBP categories, build stronger review signals, and ensure your services don’t overlap with co-located businesses. Moving to a unique address eliminates the filter entirely.
