How to find viral videos in your niche (a weekly 30-minute routine)

1of10 draws the line like this for YouTube: a spike is one video, usually tied to news, that is gone within about 72 hours; a trend is several channels rising on one topic over weeks; a format is a packaging pattern that outlives any single topic. The clock on TikTok and Reels is usually shorter, but the three kinds hold up, and each asks for a different move:

The three-creator line is our working rule, not a platform fact. It stops one account’s series from looking like a movement, and it is cheap to check: open the sound or hashtag page and count the different handles. Expect most of what you find to be spikes. That is fine. The spikes tell you what the audience reacts to; the formats tell you what you can repeat.

TikTok’s search lets you sort results by “Most liked” and narrow them by date posted (a walkthrough of the filter). It is the obvious way to look for viral videos, and it points you the wrong way for four reasons:

• It rewards age. Likes keep piling up for as long as a video is live. With a wide date range, the top of the list fills with videos that worked months ago.
• It rewards audience size. A big account’s ordinary video can out-like a small account’s breakout. TikTok says neither follower count nor a history of high-performing videos is a direct factor in what its For You feed recommends (TikTok newsroom), so small accounts break out all the time, and their breakouts are the easiest kind to learn from. Sorting by likes buries them.
• Likes are one reaction of several. A tutorial people save for later can collect fewer likes than a joke with the same reach. The sort ranks the joke higher.
• It only sees your words. The search matches your keyword against what TikTok can read from a video, such as the caption, hashtags and on-screen text. A niche hit with a vague caption can be missing from the results.

Views per day fixes the age problem:

It is a lifetime average, so it slowly falls as a video ages. A two-day-old video at 40,000 a day will not hold that pace for three weeks. That tilt toward young videos is the one you want when the question is what to film this week. The one-day minimum stops a six-hour-old video at 20,000 views from counting as 80,000 a day.

Then set each video against the niche, not against a fixed number:

Use the median, not the average. One video at 2 million views drags an average up and makes everything else look slow; with 30–50 videos, the median barely moves when one of them explodes. The audience-size problem is handled one step later in the routine, when you check each fast video against its own creator’s usual views.

Read each window on its own scale. Views per day swing hard in the first two days, so compare a young video with other young videos, never with a three-week-old one. The 30-day window is for structure, not timing: by the time an idea has topped your niche for a month, the topic is crowded, but the format behind it usually still has room.

Shortimize’s guide uses a 7–14 day window for current trends and 60–90 days for repeatable formats. We keep the windows shorter because a weekly routine needs a list short enough to open in ten minutes. If your niche posts slowly, stretch the long window to 60 days.

All 33 videos under 48 hours old were already at or above the sample’s median pace of 1.8K views a day. Those are the ones to look at again the next day.

1. Minutes 0–10: collect 30–50 recent videos. Search two or three keywords or hashtags you would use yourself, limited to the last month. Log the link, the creator, the date posted and the views. On Instagram, views show on each Reel in a profile’s Reels tab. When you later count hashtags, leave out the ones you searched for: every video carries them.
2. Minutes 10–15: work out the pace. Views per day for each video, the median of that column, and each video’s multiple. In Google Sheets, with the date posted in column C and views in D: =D2/MAX(1,TODAY()-C2) in E, =MEDIAN(E2:E51) in H1, and =E2/$H$1 in F.
3. Minutes 15–25: open the shortlist. Everything at 3× the niche pace or more, fastest first, 15 videos at most. For each, write one line: spike, trend or format, plus the mechanic. That means the hook in the first second, the structure, the length, and whether the sound carries the idea. Open the creator’s profile too: a video far above its creator’s own usual is an outlier worth studying. Small accounts behind fast videos belong on your competitor list.
4. Minutes 25–30: pick two bets. One rising video you can answer within 48 hours or a trend you can join this week, and one format to test over the next two weeks. Write the first line of each now, while the examples are open.
5. Three days after you post: score yourself. Compare your video with your own median, not with the video that inspired it. The outlier guide explains the 3× rule and why to wait three days.

Keep the same keywords from week to week. After a month, the niche pace column becomes your baseline, and you will see when the whole niche speeds up or slows down. That is worth knowing before you blame a slow week on your own video.

The free trend finder covers the first two steps for TikTok and Reels: search a keyword and the results come back ranked by views per day, with the median pace of the matches.

Beauty Reels 377 videos · median 1.8K views a day

Beauty TikTok 145 videos · median 18K views a day

Fitness Reels 128 videos · median 3.2K views a day

Food Reels 120 videos · median 3K views a day

Travel Reels 119 videos · median 1.9K views a day

Tech Reels 107 videos · median 3.4K views a day

• TikTok search. Search a niche keyword, open the filters and limit the date posted to recent weeks. Skip the “Most liked” sort for the reasons above, and remember that the search only finds videos that use your words.
• Sound and hashtag pages. Tap the sound on a fast video to see who else used it. It is the quickest way to count creators for the trend check. On Instagram, a Reel’s audio page lists other Reels that use the same audio.
• The creator’s own profile. A fast video from a creator who is always fast tells you about the creator. A fast video from a creator who is usually slow tells you about the idea. The free outlier finder checks a public account’s recent videos against its own median.
• TikTok Creative Center. TikTok’s free trend pages for advertisers list trending hashtags you can filter by industry and time frame (TikTok help). Good for broad context, but an industry is much wider than a creator niche.
• Our free pages. The trend finder searches recent TikToks and Reels from our niche samples by keyword, hashtag or sound. The trend pages list each niche’s fastest videos with sample sizes: Beauty Reels, Beauty TikTok, Fitness Reels, Food Reels, Travel Reels.

• Copying the topic instead of the mechanic. The hook, the structure, the length and the role of the sound carry over to your account. The topic and the script belong to someone else.
• Chasing a spike days late. A spike whose newest copies have stopped picking up speed is finished. If you can’t post within 48 hours, take the format instead.
• Counting videos instead of creators. One creator posting the same idea five times is a series. Three unrelated creators posting it in one week is a trend.
• Mixing platforms in one median. TikTok and Reels paces in the same niche can sit far apart, so a mixed list ranks one platform above the other. Keep a niche pace for each.
• Judging your own test on day one. Give it three days, then compare it with your own median. One flat test says little; two or three tries of the same format say a lot more.
