Google Web Master Tools: Duplicate Title Tags?

[asc76]

According to Google Web Master Tools it says my site has 910 Duplicate Title Tags. How verbose should title tags be? What's the maximum character length?

For example, let's say I have an image of an iPhone 4S being held in someone's hand. How verbose of a title and how many characters am I allowed to have? Is the goal with title tags to be very specific in describing the image? In the above example, do I need to say something like: "iPhone 4S being held by white caucasian male" or will "iPhone 4S" suffice?

As long as the title is relevant to the image, iPhone 4S would be fine..

Try and keep your titles below 70 characters...

If you have a URL that have multiple pages then you should have a look at this..
