TL;DR Shorts are great top-of-funnel, but YouTube explicitly says URLs in Shorts descriptions/comments aren’t clickable. Build a link funnel that uses native clickable surfaces: end screens, info cards (if eligible), related-video links, and channel profile links.
1 Know what’s clickable (official)
YouTube Help explicitly notes:
URLs placed in Shorts comments and Shorts descriptions are non-clickable (anti-spam measure).
In the “clickable links overview”, YouTube marks end screens as clickable, and related videos in Shorts as a clickable link surface.
YouTube also notes: to add clickable external links, you must enable your channel’s access to advanced features.
2 End screens: your default “bottom CTA”
Per YouTube Help:
End screens are added to the last 5–20 seconds of a video.
The video must be at least 25 seconds long.
You can add up to four elements for standard 16:9 (other aspect ratios may have a lower limit).
Instavar tactic: Write your CTA into the script so the end screen isn’t a surprise. Viewers should already know what to click.
3 Info cards: your “mid-video CTA” (and external links)
Per YouTube Help:
Info cards can feature a video, playlist, channel, or link.
YouTube notes you can add up to 5 cards to one video.
For external website links, YouTube states the “Link” card requires being in the YouTube Partner Program, and your linked site must comply with policies (Community Guidelines and Terms).
Instavar tactic: Use one card early (set expectation), and one card late (capture intent).
4 A simple Shorts → Long-form → Lead funnel
Step 1: Shorts as the “hook”
Publish Shorts that earn attention and qualify intent.
Don’t rely on raw URLs in the Short’s description/comments (non-clickable).
Step 2: Use a clickable bridge
Pick one (based on your channel setup):
Related video link in Shorts → send viewers to a long-form “explainer” video.
Channel profile link → send viewers to the canonical landing page.
Step 3: Close with end screens and/or cards
End screen: “watch next” + “subscribe” is a clean baseline.
If eligible, add an external link info card to the offer page.
