How to place ads on specific posts or pages

I want to put some affiliate banner ads on blog posts with relative content, but they all show up on the front page instead of on the specific post where I want them. I am cutting and pasting clickbank codes. So, if I have a post on travels in France, how would I place a French language course image ad on that specific post?

Hi @chicotito1,

I hope you are well today and thank you for your question.

You can try achieving this using any of the following plugins.

Best Regards,
