Using Page Title with Node Tags I'm using the following modules


Meta Tags
Page Title


I need to be able to make the sites title work like this:

Use the title set in Meta Tags for each Node first of all, if this isn't set then default to the Page Title module.  

If this isn't set, just use the pages title.

How do I set a precedence for the titles?  Do I have to hook into html_head_alter?

Any help is greatly appreciated,

Cheers
Have you checked the auto nodetitle module with the token Module. Then you can create the node Titles with tokens.
Check also the Automatic Entity Label i think its better for your Usecase
