Now automatically put a “Read More” link for each of your WordPress post after the first image and the first paragraph using Auto Read More Generator plugin. In case when the image is not present in the beginning then it will only show the first paragraph and the read more link after that.
So If you are interested in adding Read More link automatically in your posts then first of all install and activate Auto Read More Generator plugin and then replace the_content() with the_content_with_readmore_link() at blog post page. That’s all.
friend do not understand where this helps me how it works the_content() with the_content_with_readmore_link()
The plugin has not been updated since long.
