There is an other simple way to replace words by an affiliate link, all you have to add the following code into your function.php file. This is the simple and free way but have limitations and will not give you as much control as the SEO Smart Link plugin. Don’t forget to enter your words/links as shown in the example code.

function replace_text_wps($text){
	$replace = array(
		// 'WORD TO REPLACE' => 'REPLACE WORD WITH THIS'
		'wordpress' => '<a href="#">wordpress</a>',
		'excerpt' => '<a href="#">excerpt</a>',
		'function' => '<a href="#">function</a>'
	);
	$text = str_replace(array_keys($replace), $replace, $text);
	return $text;
}
add_filter('the_content', 'replace_text_wps');
add_filter('the_excerpt', 'replace_text_wps');
