Passive Index



The Passive Index is a readability score. That is, it is a measure of how easy or difficult it is to read a particular text. In fact, the Passive Index is simply the percentage of sentences in a particular text that contains passive verb forms.

There are 16 sentences on the page entitled Easy-To-Understand Writing. Only two of these sentences contain a passive verb form. Consequently, that page has a Passive Index of 2/16 or 0.125.

In contrast, there are only four sentences on the page entitled Privacy Policy and none contain passive verb forms. Therefore, that page's Passive Index is 0.00.

Try to keep the Passive Index of your writing well below 0.20.
