Business Citation Issue

[urhaiurg]

Hey Experts, I have a website which is providing local business services to US clients. For this purpose, I have created the separate landing pages for each client.

Now my question is that I have done citation for that particular landing page not for the root domain. Now the client has decided to stop working with us and I removed the business name and detail from that landing page but the landing page still exist on dummy business name. But citation of that business page still exists. Then how that business citation can affect that linked page?

I mean it will affect the page ranking or Google trust or relevancy?
