I am not able to find this code in xml file. For example - https://www.digitalmarketingmart.com/sitemap.xml Are you finding this code in sitemap.xml file (As this question is under sitemap section) or you are finding this code in analytic code?
It is not the complete path. /wp-content is the key folder that contains your website content, themes and plugins installed on your website. .map files are source map files that are for minified JS, CSS and TS files No, if it was from Google ads then you could be able to see it in your Google Ads account report. BTW, it is an old thread so have you got it where the traffic has come?
