We are in the process of moving our blog to a new provider. It was previously hosted on Wordpress and individual blog posts used the format :
On our blog listing page
mysite.com/blog, all of the links to individual posts followed this format.
Our new site has a different url structure for individual posts
mysite.com/slug. We have built an add on so that if the old url is requested, the page will still show the post, so it is not a broken link, however our listings page does not retain the old URLs and shows the new format.
So the old listing page had something like:
<a href="mysite.com/2019/08/20/tariners.html">Best Trainers</a> <a href="mysite.com/2019/04/20/shirts.html">Best Shirts</a>
but the new site has
<a href="mysite.com/tariners.html">Best Trainers</a> <a href="mysite.com/shirts.html">Best Shirts</a>
Will this change to the listings page have a negative affect on the individual posts SEO ranking?
