Keyword Linking is a flexible component that helps you easily add links to keywords and phrases in Joomla, K2, Zoo content, and link them to corresponding urls. Joomla originally supports links in its content but setting links for same keywords in many contents is very time-consuming. That’s why you need a stronger and more dynamic autolink extension.
Joomla provides a function for including links in articles but Joomla users always have to deal with setting and typing in the links. The second word function isn't linked because the first word was linked (Links Limit).
