Thanks for getting back to me Patrick - I have managed to implement however paragraphs for the category archive pages as I wanted to utilize these also for example :
Chicken Breast Recipes
Chicken breast information and details on cooking with chicken
Therefore - when optimising for "chicken breast recipes" I wanted to optimise the category archive itself.
Is this not a good idea then? As I have a fair few categories I would like to add information too? Also I was under the impression it may help me to have the categories such like this www.domain.com/chicken-breast-recipes/chickenpost.
I have looked at the Yoast set up - would I have to go into each post/recipe and add the direct canonical url within the SEO page info at the bottom ?
Thank you for your time.
