Is it possible to add an advertisement to the city in the permalinks?
meaning
add an ad
When adding a city
The advertisement is linked to the city and address
http://localhost/newyork
The address appears in the name of the city
I hope you understand what I mean
Thanks

Not clear if you want to create city URL or add coty to item url

I want to add ads in a specific city
private page
But without using custom pages
The URL is associated with the same city name

If you search only for city, you get city specific URL, like:
https://plugins.abprofitrade.eu/sergeantsville-c439046

You didn't understand what I mean
1 - URL
http://localhost/newyork
For example, according to the name of the city
http://localhost/texas
2 - This page appears without the search page
Only city-specific as a major feature.
3 - When you add an advertisement, a button is allocated
Do you want to be a separate page?
thank you

If you search only for city, you get city specific URL, like:
https://plugins.abprofitrade.eu/sergeantsville-c439046

I can see city name in URL 

Yes you can see the city here
https://plugins.abprofitrade.eu/sergeantsville-c439046
What do you mean the city appears without
-c439046
thus
https://plugins.abprofitrade.eu/sergeantsville
But it is not linked to the search page
what i mean
A private page that is different from the search page
I mean, each city has its own page

Osclass require ID in URL, as there is usually many cities with same name.

But better question is, why would anyone care if there is ID in URL?

• human does not care, will never "remember" url based on city. anyone that thinks single person will do it is wrong.
• crawling bots does not care if there is ID or no, they just care if URL is friendly or no. Non-friendly URL contains &, ? chars
