The companies we recommend for WordPress web hosting above usually let users choose their own data center. A specific geographic location and the data center at that location do have an impact on a website.
If your website's target audience is in the United States, you should choose a data center located in the United States. If your target audience is in Europe, you should choose a European data center.
If you're really not sure which data center to choose, you can also choose to use the WordPress CDN service to speed up your website across all geographic locations.
