Yes, Google personalizes results based on your location because it tries to show you the most relevant answers. If you search for "best electrician" from Lagos, you will see different results than someone searching the same words from London. Even broader searches like "best phone to buy" can show different results because Google considers local availability and popularity. This is why businesses doing SEO need to think about where their customers are located, not just what words they use. Does Google's location-based search results change how you think about keyword research?
