Hi @xaviermi,
Is that URL of a regular post or a custom post type? If you are using any plugins to create ads and it saves them as custom post types, then you can noindex them by going to SEO → Search Appearance → Content Types, as in this guide.
What is the error that Google has reported in Google Search Console for that URL? Your screenshot does not contain the error/warning message.
We are looking forward to hearing from you.
I don’t know, the plugin used for ads is “Advanced Ads” (by Thomas Maier).
The error on Google Search Console: “Indexed but blocked by robots.txt”
“Indexed but blocked by robots.txt”
This warning means that Google found the URL, added it to the index but blocked it from being included in search results because the robots.txt file says to exclude the wp-admin URLs.
First, this is acceptable and you do not necessarily need to do anything. That being said, if you would like to resolve the issue, you would need to locate where Google found the URL. This is most likely a link on your site that mistakenly links to the edit page for the ad instead of the ad URL.
