Definition and effect on reader

A logical structure is a way of identifying a piece that is easy to follow in its progression of ideas or arguments. This can manifest itself in any number of ways but generally allows for the reader to see the arguments behind a particular point of view and then continues on in an attempt to persuade them to adopt that point of view into their own life.

Example

For example: consider if the Australian Red Cross was trying to persuade you to donate blood. A logical structure might look like this:

1. Establishment of why giving blood is a good idea (through evidence and anecdotes)
2. Ask you to give blood (perhaps adding a time frame which adds urgency)
3. Provide you with the means to do so (provide a phone number, email address or address)

This sort of structure can be accommodating because it allows the reader to follow along easily and can position the writer as logical, and therefore more credible.
