I have a recipe site that make dynamic urls for each page. Like this: site.com/view_recipe.php?id=7226&recipe_title=Pork_with_chili_ Now, I want to transfer the site to Wordpress and will get new urls like site.com/pork-with-chili. I got tons of deep inlinks from to the current pages. How should I keep the link juice while changing urls? There are about 6000 pages on the site.
