Same phone numbers on different sites, why is it bad?
Customers often do not hesitate to have several sites about the same phone numbers. But judging by my many years of experience, I can say that they must be different. Take for example Google maps, if there are several addresses with the same phone, you will be identified as a branch.
Search engines index all the text on the site, the recent case once again convinced one customer that there should not be the same phone number. Some say and what a difference we have sites of completely different subjects. On the example of the cities of the USA, each as a separate country for Google :)
And for a basis I think take contact data, including telephone numbers, which in each region are different.
In a word, two sites - two different phone numbers, and only so!
