READING THE NUMBERS: - 12,400 impressions: The video was shown many times, so these numbers are fairly steady to read. - CTR 3.1%: Click-through rate is the share of people who clicked after seeing the video. Yours is lower than your usual 5.5%. - Average view duration 2:10 of 9:00: People watched about 24% of the video. Your usual is about 38%, so this is lower too. - Biggest drop at 0:40: Many viewers left in the first minute. THE MAIN THING: Both numbers are below your own usual, but the click-through rate suggests the title or thumbnail is pulling less than it normally does, and the 0:40 drop suggests the opening loses people. With 12,400 impressions, this pattern is probably real and not random. TEST THIS NEXT: Change only the thumbnail text on this video, since you can do it without re-uploading. Then compare click-through rate over the next 7 days with the 3.1% you have now. Leave the opening for your next video so you can tell which change did what. DON'T CONCLUDE THIS YET: Don't conclude the topic is the problem. Your numbers show the packaging and the opening, not whether people want bookshelf videos. Also don't assume the 0:40 drop is the opening itself until you watch what happens right there. PASTE THIS NEXT TIME: Traffic sources (search, browse, suggested) and the click-through rate for two or three of your best videos, so I can tell if this video reached a different audience than usual.
