In-Subtitle Advertising

In-subtitle advertising places a short brand message at the beginning and end of eligible subtitle files delivered through supported media-player APIs. It offers broad multilingual distribution outside conventional search and social advertising auctions.

The public economics are simple: $0.50 CPM and a $5,000 minimum. At that rate, the minimum campaign purchases 10 million delivered insertions. An insertion is recorded when an eligible subtitle file containing the message is returned through the API; it is not a verified human view.

The format is best for memorable awareness. Subtitle text is not natively clickable, so a short URL, memorable domain, promo code or dedicated destination is required when the campaign needs attributable response. Inventory depends on language, geography, content and device criteria.

A measurable destination can be produced through Web3 landing pages. Broader evidence and attribution rules can be planned through marketing analytics and attribution.

This engagement is useful when the team has a defined decision to make and the following conditions are present.

• Broad awareness matters: the campaign needs large-scale brand exposure at a known delivery price.
• Conventional auctions are saturated: the team wants an additional reach layer rather than another social placement.
• International testing is useful: language and geography filters can explore available markets.
• The message is simple: the product can express one memorable idea within two short lines.
• A launch needs frequency: repeated beginning-and-end placement can reinforce an approved campaign message.
• Attribution can be designed: the campaign can use a dedicated destination, domain or promo code.

This is not suitable when the only objective is immediate click-through, verified attention or last-click acquisition. The message is visible in subtitle text but is not a native clickable ad unit.

Suitability check: determine whether awareness, format and attribution constraints match the objective.
Inventory estimate: review available volume by language, geography, content and supported device criteria.

Message design: reduce the offer to a clear, compliant two-line message.
Campaign configuration: set targeting, beginning-and-end placement, frequency and delivery limits where available.

Attribution setup: prepare a memorable URL, landing page, promo code or campaign identifier when appropriate.
Delivery control: monitor the campaign dashboard and report insertions separately from attributable response.

The managed campaign includes the agreed combination of:

Core working files.
Channel-suitability and campaign brief.
Inventory estimate for selected filters.
Targeting and delivery configuration.

Execution and governance.
Subtitle-ready message variants.
Campaign setup and launch.
Frequency and daily-limit settings where supported.

Measurement and handoff.
Dashboard delivery report.
Dedicated URL or promo-code measurement when scoped.
Post-campaign findings and recommendation.

The report keeps three numbers separate: purchased insertions, delivered insertions and attributable actions. None is renamed as verified attention.

1. Confirm channel fit. Define the objective, audience, message, budget and acceptable attribution limits.
2. Estimate inventory. Review available scale across requested languages, geographies, content and devices.
3. Design the message. Create concise variants that remain understandable within the subtitle format.
4. Prepare attribution. Configure a dedicated destination, memorable identifier or promo code when response measurement is required.
5. Launch and control delivery. Apply approved targeting, placement, frequency and delivery limits.
6. Report the evidence. Separate API-delivered insertions from visits, registrations or sales measured through the campaign setup.

Crynet has worked in crypto and Web3 marketing since 2016 and understands why unconventional inventory needs more—not less—clarity about what is being counted.

We publish the customer economics and state the limitation directly: delivery is an eligible subtitle API response, not guaranteed attention. This lets the buyer compare the channel honestly with other awareness options.

Crynet also connects the placement to message, destination and measurement, so low CPM is not presented as a complete strategy by itself.

Commercial baseline. The public rate is $0.50 CPM with a $5,000 minimum. The calculation is therefore: 10,000,000 insertions ÷ 1,000 × $0.50 = $5,000.

Campaign evidence is reported in layers:

Planned: approved budget, targeting and estimated inventory.
Delivered: eligible subtitle files returned with the campaign message.

Attributable response: visits or actions recorded through dedicated campaign mechanics.
Unknown: human attention and influence not established by the delivery event.

Final inventory varies with filters and campaign period. Supplier economics remain private and are not presented as the public Crynet price.

Useful first brief. Send the current URL or materials, target audience and markets, deadline, available evidence and the decision the work must support. Crynet will identify the smallest sensible first scope and the inputs still missing. Send the brief.

What counts as a subtitle insertion?
An insertion is recorded when an eligible subtitle file containing the campaign message is delivered through the supported API. It is not a verified human impression.

Where does the message appear?
It can be placed at the beginning and end of the eligible subtitle file.

What does the minimum campaign deliver?
At $0.50 CPM, the $5,000 minimum purchases 10 million delivered insertions.

Can the campaign target specific audiences?
Available criteria may include geography, subtitle language, genre, keywords, specific titles, release year and supported devices. Volume varies by filter.

Can viewers click the message?
No. Subtitle text is not natively clickable. A short URL, memorable domain or promo code can be included.

How is response measured?
The dashboard reports delivery. Dedicated destinations, URLs or promo codes can measure attributable visits and actions where the setup supports them.

Which language has the most inventory?
English currently provides the largest available volume, while scale in other languages and markets varies.

Can Crynet guarantee attention or conversion?
No. Crynet can report eligible delivery and attributable response, but not guarantee that every delivered subtitle was read or influenced a decision.

What should we send for an estimate?
Send the product, target geographies, languages, content preferences, campaign period, budget and the message or action the campaign should support.
