What is the direct effect on search ranking when a video consistently gets 'likes'?

The direct effect on search ranking when a video consistently gets 'likes' is an increase in the video's perceived relevance and quality by the YouTube algorithm, leading to a higher ranking in search results for relevant keywords. 'Likes' serve as a positive signal to the algorithm, indicating that viewers appreciate and approve of the video's content. This positive feedback contributes to the video's overall engagement score, which is a key factor in determining its search ranking. A higher engagement score signals that the video is valuable and relevant to viewers, making it more likely to be shown in search results and recommended to other users. The algorithm interprets a consistent stream of 'likes' as evidence that the video is meeting the needs of its target audience and deserves greater visibility.
