Replace the [...] more link with custom text for each post, creating a specific call-to-action.

For example, here's a post about interior design, the more link reads "See our top tips for cosification"
Turn your “More” links into a bespoke call-to-action for each post. Rather than have “Read more” or “[…]” after your excerpt, you could have “See Bob’s garden up close” in a post about a beautiful garden, or “Try our tasty sauce” in a bolognese sauce recipe.
