Double check the section labeled, “For each article in a feed, show”. You want to make sure this is set to Summary. Once you do that, make sure you click on the “Save Changes” button.
Now, some of you might ask, “Isn’t this what excepts are for?”. The excerpts are more about having an optional hand-crafted summary of your content in the post. Inserting the “Read More” tag simply says to tease your post with the first paragraph.
Another downside of using excerpts is that not all WordPress themes support them being used. The Read More tag is much more widely supported due to the fact that it is easier to work with and code for when designing a WordPress theme.
