An E-Commerce site has PDF coupons that expire after a certain date. What is the best way to handle them? I've heard allowing 404's aren't great for SEO and 301 redirects can clog up the .htaccess.
There is already a landing page generated through internal links if a coupon is expired, so ideally I would like a way to capture requests to expired assets and redirect to that page.
I'm curious, what ways are there to handle this?
