How to tell if a TikTok video is an ad: is_ad and other signals

November 8, 2026

If you analyse creator content, you need to separate paid posts from organic ones. A sponsored video with ad spend behind it will have more plays than the creator's normal work, and mixing the two distorts every average. There is no single perfect flag, but there are several signals you can combine.

Signal 1: the is_ad flag

TikTok's own video data includes a true or false field called is_ad. Treat true as the strongest machine-readable sign of paid distribution. It does not tell you about a gifted product or an undisclosed deal, and a creator's post can be organic one week and boosted the next, so record it with a date.

Signal 2: the disclosure label

TikTok has a commercial content disclosure setting. When a creator turns it on, they pick "Your brand" or "Branded content". Branded content shows a "Paid partnership" label, and the setting adds a commercial content label to the post source. This is the creator saying "a brand is involved", which is a different fact from "this is running as an ad".

Signal 3: caption words

Many creators disclose in the caption: #ad, #sponsored, #partner, "paid partnership with", "thanks to @brand", "use my code". These are easy to match with a regular expression. Watch for false positives such as #adhd or #adventure.

Signal 4: a brand tag, a code or a product link

A tagged brand account, a discount code, or a TikTok Shop product link on the video are commercial signals. A product link alone may be affiliate content rather than a paid deal, so record it as "commercial", not "paid".

Signal 5: the ad library

If the video ran as an ad to users in Europe, TikTok's Commercial Content Library should have it, with dates, targeting and reach source. Coverage is the EU, EEA, Switzerland and the UK only source.

A scoring checklist

Signal	Points	Classify as
is_ad is true	3	Paid distribution
Found in the ad library	3	Paid distribution
Paid partnership label	2	Sponsored
#ad, #sponsored or "paid partnership" in caption	2	Sponsored
Discount code or brand thanked in caption	1	Commercial
Product link only	1	Commercial

Score 3 or more: exclude from organic benchmarks. Score 1 to 2: keep, but tag it. Score 0: treat as organic, while knowing some deals go undisclosed.

import re
SPONSOR = re.compile(r"(#ad\b|#sponsored|#partner\b|paid partnership|#gifted)", re.I)
COMMERCIAL = re.compile(r"(use (my )?code|discount code|link in bio|thanks to @)", re.I)

def ad_score(video):
    s, cap = 0, video.get("caption") or ""
    if video.get("is_ad"):
        s += 3
    if SPONSOR.search(cap):
        s += 2
    if COMMERCIAL.search(cap):
        s += 1
    return s

Why the label alone is not enough

The US Federal Trade Commission tells influencers to disclose any financial, employment, personal or family relationship with a brand, including free products. It also says not to assume that a platform's disclosure tool is good enough, and that in videos the disclosure belongs in the video itself source. So a compliant sponsored post may carry the label, a caption tag and a spoken mention, and a non-compliant one may carry none. Your score is a signal, not proof. This is not legal advice.

Practical uses

Clean benchmarks: report a creator's organic median plays separately from sponsored ones.
Competitor deal mapping: list which creators a brand works with by scanning creators' recent videos for that brand's tag and sponsor words.
Rate sanity check: compare a creator's sponsored median plays to their organic median. A big drop means their audience tunes out ads.

Edge cases

Brand accounts. Every post on a brand's own account is commercial. Score creators, not brands.
Affiliates. Creators who earn commission on Shop links may not label posts as paid partnerships. Track them as commercial.
Old posts. A video from last year can be boosted today. Re-check before you report.
