Audience means the kind of reader or listener the text was intended for. As this is unlikely to be you, you need to attempt the near impossible and 'become' the intended reader. Always consider a text in this way or you will run the risk of 'misreading' it. Also, avoid being overly specific or informal when describing an audience’s likely characteristics: 'this writing is suitable for clever so and so’s of about 23 and over' sounds rather less impressive than, 'the style of this text seems geared towards an educated and sophisticated adult audience'.
