Do Google Search Results Change with Location?
Introduction
Question: If we type the same query into Google from different locations, do we get the same answers?
Short answer: No. Search Engine Result Pages (SERPs) vary by many factors — location is a major one. For example, "best food" searched in Mumbai will return different results than the same query from Tokyo.
In this post I describe a small experiment: I ran the same queries from five countries, compared results using Jaccard similarity, and visualized the differences with heatmaps.
Experiment setup
I tested 5 countries and 9 queries grouped into three categories:
- Countries: United States, India, Japan, Brazil, Germany
- Query categories (3 each):
- Neutral: climate change facts, latest AI research, mathematicians
- Cultural: best food, cultural values, nationalist
- Commercial: best laptop, study abroad programs, buy electronics online
All searches were performed on Google using SerpAPI. Each query-location pair used the top 10 organic results. The experiment metadata (timestamps, location, search IDs) is available here: metadata.csv.
Jaccard = (A ∩ B) / (A ∪ B)
The result is a 5×5 symmetric matrix (locations × locations) for each query.
Results (high level)
Overall, the data shows location affects search results. The effect is strongest for Commercial and Cultural queries and weaker for Neutral queries.
Cultural queries — example: cultural values
Below is the heatmap of Jaccard similarity for the query cultural values. Higher values mean more overlap in the top-10 results between two countries.
Commercial queries — example: best laptop
Commercial queries like "best laptop" show much less overlap between countries — many results differ because country-specific retailers, local review sites, and regionally-preferred brands appear.
Notes: Results above are computed from only the top 10 results per location. Expanding to top-50 would give a fuller picture, but is slower and requires more careful de-duplication.
Conclusion
This simple experiment supports the common belief: Google SERPs vary significantly by location, especially for queries influenced by culture and commerce.
Next question: can location-based results introduce bias? I plan a follow-up experiment to explore that — stay tuned.
