It is a well known fact that your regular visitors don’t click on your ads. In order to monetize your blog without annoying your loyal readers, what about displaying ads only when posts are older than 15 days?

To achieve this recipe, simply open your functions.php file and paste the following code in it:

function is_old_post($post_id=null){
   $days = 15;
   global $wp_query;
   if(is_single() || is_page()) {
      if(!$post_id) {
         $post_id = $wp_query->post->ID;
      $current_date = time();
      $offset = $days *60*60*24;
      $post_id = get_post($post_id);
      $post_date = mysql2date('U',$post_id->post_date);
      $cunning_math = $post_date + $offset;
      $test = $current_date - $cunning_math;
      if($test > 0){
         $return = true;
         $return = false;
      $return = false;
   return $return;

Once done, you are now ready to call the functions in your single.php template as shown below:

<?php if(is_old_post()){ ?>
<?php } ?>

That’s all, you’re done. By default, ads will be displayed on post older than 15 days. To change this value, simply edit the $days variable on line 2.
