In the WordPress Templates we generally see the “Read More” links at the end of the small excerpt text. Do you want to change the text to something else? Then please follow the steps :

1. Navigate to Appearance –> Editor in your WordPress Dashboard
2. Open your “index.php” or file and find this line:

<?php the_content(__('Read more'));?>

3. replace it with this one: 

<?php the_content("YOUR OWN TEXT" . the_title(",",false), 0); ?>
