Google SERP Preview Tool
This tool will display Google ads country-wise for any keyword or website. Google Ads can also be filtered by the geographic location ( or country ) of the visitor. If this tool fails to display ads for a particular keyword or web domain, chances are that it is a restricted keyword or the domain is not part of the AdSense program. Google ads can be restricted on domains and web pages that include adult or mature, gambling-related, copyrighted, violent, or hateful content.
