Marketers sometimes worry that shortening a link to a blog post or product page will tank its search ranking. It won't — as long as the shortener uses the right kind of redirect. Here's what's actually happening under the hood.
A 301 redirect means "moved permanently." Search engines treat the destination page as the real, canonical URL and pass ranking signals to it. A 302 means "moved temporarily," which search engines treat more cautiously and may not pass full ranking value. Always check that your shortener uses 301s — yxl does, by default, on every link.
Usually it's not the redirect type — it's chaining. If a link goes through three or four shorteners stacked on top of each other, each hop adds latency and risk of a broken link. Stick to one shortener per link.
Don't use expiring short links for anything you want ranked long-term. If the link dies, so does the traffic and the SEO value tied to it. Use permanent redirects for evergreen content.
