Automatically insert the page title into post as a keyword

I’m looking for a plugin, ideally, that would automatically insert the page title into the page/post content in a specified place.

So, for example, if the page title was “Dog Training”, I could specify a shortcode or a merge tag like %page_title% and it would appear where I want into the page/post’s content.

The use case – I’m generating hundreds of landing pages on an automated basis with keyword-targeted page titles and would love to include the keyword on the page.

Any ideas? Thanks in advance for your response!
