YouTube likes

A YouTube like is a thumbs-up on a video. The dislike count was hidden from public view in late 2021 — creators still see it in Studio, but viewers only see the like number.

Likes are a positive confirmation signal in YouTube's ranking. They are meaningfully less important than watch time and retention, but high like-to-view ratios (typically 3–5% on a healthy channel) contribute to suggested-video placement.

Likes also do two softer things:

• Anchor social proof under the title, where a low like count on a high-view video signals weak content.
• Trigger the "Liked videos" playlist on a viewer's profile, which drives a small but real repeat-view loop.

Paid like services are most often used at launch to clear the first-impression threshold — a few hundred likes on a new upload normalizes the look of the video and smooths the early signal curve.
