I'm working on the website of a client.
They have their contact details as a section in the text body of every single page, with <h1>Contact</h1> tags.
I suppose they did it because they are local and want to stress the importance of serving their local community.
I have a concern: is there any risk Google may treat it as duplicate content and penalize the site?
I would like to suggest the client removing at all the contact section, and instead placing the contact details on the footer and marking them with Schema.
