YouTube Comments Scraper

Collect public YouTube comments with commenter, engagement, video, and channel context from one or more video URLs.

概要

Turn public YouTube conversations into a structured dataset without manually opening each video and copying comments one by one. For every available top-level comment, the result keeps the comment text together with its public author handle, engagement signals, and the video and channel context needed to interpret it.

This combination is useful when a research, marketing, support, or content team needs more than an isolated quote. It lets analysts connect what viewers said with the video they reacted to, distinguish creator participation from audience participation, and retain visible engagement snapshots for later comparison.

Data notes

The data comes from publicly accessible YouTube video pages and their visible comment sections. Each record represents one top-level comment. Comment ID identifies the comment, while Video ID and Video URL identify the video that received it. Reply Count reports the number of replies shown for that comment, but reply messages are not separate records in this dataset.

Comment Time preserves YouTube's displayed text and may be relative, such as “10 years ago,” rather than a normalized timestamp. Comment Like Count, Video Like Count, Video View Count, Video Comment Count, and Channel Subscribers are text snapshots observed at collection time and can change later. Channel-owner Comment, Creator Heart, and Comments Disabled are also supplied as source text rather than converted booleans. Private, removed, restricted, or comment-disabled videos may not provide comment records.

What the results look like

Each record represents one public top-level YouTube comment and its video context.

Comment ID	Comment text	Comment time	Comment like count	Video title	Channel name
UgiH2bCFcyVmAHgCoAEC	Want to try it out :)	10 years ago	1	What is web scraping - Octoparse, your first web scraper!	Octoparse
UgxExampleComment002	This walkthrough answered my setup question.	2 years ago	3	What is web scraping - Octoparse, your first web scraper!	Octoparse

Other available fields include Commenter Handle, Commenter Avatar URL, Reply Count, Creator Heart, Video ID, Video URL, Video Description, Video View Count, Video Like Count, Video Comment Count, Video Thumbnail URL, Channel Handle, Channel URL, Channel Avatar URL, and Channel Subscribers.

Use cases

For audience feedback analysis, group Comment Text by Video Title to identify recurring questions, objections, praise, and requests around each video.
For engagement review, compare Comment Like Count and Reply Count to find comments that generated the strongest visible reaction from other viewers.
For creator-community analysis, use Channel-owner Comment and Creator Heart to distinguish direct creator participation from ordinary audience discussion.
For channel research, combine Channel Name, Channel Subscribers, Video View Count, and Video Like Count to retain the public context surrounding each collected comment.

適用範囲と境界

Each run accepts 1 to 10,000 public YouTube video URLs; an optional limit can request 20 to 5,000 comments per video, while unavailable, private, restricted, or comment-disabled videos may return no comment records.

適している用途
Use it when you need public comment text and engagement details for one or more YouTube videos.
Use it to study audience questions, reactions, recurring topics, or creator interaction around public videos.

適さない用途
Do not use it for private, removed, age-restricted, region-restricted, or otherwise inaccessible videos.
Do not use it when you need reply-thread records rather than top-level comment records.

失敗時の処理

作者が宣言した失敗時と再試行の動作です。連携時にはシステムプロンプトに含めることをおすすめします。

1If a run fails, retry the same small URL set once; if it fails again, split a large batch into smaller groups.
2If no records are returned, confirm that the video is public, still available, and has comments enabled before retrying.
