Simply appending country codes to URLs will not lead to any significant changes in regional ranking.
Such modifications may cause temporary fluctuations, but they won’t have a long-term impact on achieving strong rankings in those regions.

Instead, consider using a ccTLD (country code top-level domain), which is typically reserved for or associated with a specific country, sovereign state, or dependent territory. This approach ensures clear segmentation for each country and section of your website. Merely incorporating country codes into URL structures is not sufficiently distinct or effective.
Regional targeting… It seems straightforward, yet even today, not everyone fully understands it.
