When buyers search for a horse, they describe their wishes to the Horse Agent in their own words. Your description text is therefore crucial for the matching engine to understand whether your horse is a good fit.
Make sure to include:
Temperament and personality: How is the horse in daily handling and under saddle?
What it's used to: Is it traffic-safe, easy to load, used to hacking alone or in groups, clipping, etc?
Rider and context: What type of rider or home would the horse thrive best with?
Be completely honest about both the horse's strengths and its challenges. This saves time for both you and the buyer and leads to a safer deal. See the guide: How to attract the right buyers through the Horse Agent.
