The conditions that have to be met before a link will be placed are:
A maximum of 1 link per sentence wil be placed
A maximum of 2 link per paragraph wil be placed
Sentences that already contain a link will not receive a SmartWord
Links are only placed within paragraph(<p>) which in turn is in an <article> tag, this is to make sure SmartWords are only inserted into actual content
Links are not added on images, bold text, italic text or other text that has an HTML entity around it such as H1 and H2
Content can be excluded for SmartWord insertion by adding class="pzz-ignore" to the containing element.
