What Is Influencer Casting? How It Works and the Request Process [Basics Explained]
This article was automatically translated from the Japanese original. Read the original in Japanese
Influencer casting is the work of selecting influencers who fit a brand or service, negotiating their involvement, and managing the posts through to completion. It's not just about deciding "who should post"—it refers to the entire process, from organizing requirements through to reviewing results.
| Task | Description |
|---|---|
| ① Requirement definition | Aligning with the brand on who they want to reach and what message they want to deliver |
| ② Candidate selection | Identifying candidates that match the requirements and compiling a list after checking engagement and past posts |
| ③ Negotiation and contracting | Aligning on terms and formalizing post content and publication timing as a contract |
| ④ Post direction | Creating a brief and overseeing the post content |
| ⑤ Implementation management | Confirming that posting timing and PR disclosure are appropriate |
| ⑥ Reporting | Organizing post results and sharing them with the brand |
The Scope of Casting Work
When people hear "influencer casting," most imagine a job that involves "finding someone who seems like a good fit and reaching out to them." In reality, candidate selection (②) in the table above is only a small part of the overall process. In requirement definition (①), we align with the brand on who they want to reach and what they want to deliver. This is where we put into words the target age group, interests, the platform they want posts on, and any expressions to avoid. In candidate selection (②), we identify a broad range of candidates that fit the requirements, then compile a list after checking not just follower counts but actual engagement levels and past post content. In negotiation and contracting (③), we align on terms and formalize post content and publication timing as a contract. In post direction (④), we create a brief that conveys the brand's intent and oversee the post content. In implementation management (⑤), we confirm whether posting timing and PR disclosure are appropriate. In reporting (⑥), we organize the post results and share them with the brand.
Of these six tasks, only part of ② is visible from outside the organization. If requirement definition remains vague when candidate selection begins, the brand's intent and the actual post content will diverge further down the line, leading to more back-and-forth revisions. Conversely, the more time spent on initial requirement definition, the more smoothly the later stages proceed. The reason we place such emphasis on hearing out requirements before presenting a candidate list is that any misalignment at this stage directly affects the final quality of the posts.
Moreover, these six tasks are not independent—the results of each stage form the premise for the next. Information missed during candidate selection can become a source of trouble during negotiation, and if post direction remains vague, discrepancies can arise during implementation management that simple PR disclosure checks cannot catch. This is precisely why we value having the same team oversee all six tasks as a continuous flow, rather than dividing them among separate staff.
The Process from Request to Completed Post
From the client's perspective, the standard process consists of the following six steps.
- Consultation — You share your objectives, the product or service, and an image of who you want to reach. It's fine if some details aren't fixed yet—we'll help organize them.
- Requirement organization — Together, we organize the target demographic, the platform you'd like posts on, the aesthetic and tone you'd like to reference, and any expressions to avoid. Sharing past post examples or brand guidelines at this stage helps improve accuracy.
- Candidate list proposal — We present a list of candidates. You review each candidate's profile and past post content and give us feedback.
- Selection and negotiation — You select the final candidates, and we handle the negotiation of terms and the contracting process.
- Execution — We conduct briefings, review content before posting, and check PR disclosure and display status after posting.
- Reporting — We compile the post results and share them as a retrospective.
Steps 2 and 3 place the greatest burden on the client. The resolution of the information shared at this stage directly determines the accuracy of the candidate list. Conversely, if you take the time to properly address these two steps, the subsequent selection, negotiation, and execution will proceed remarkably smoothly.
Step 6 exists to ensure the project doesn't simply end once the post goes live. By reviewing the post-publication response and whether it reached the intended audience together with the brand, requirement organization for the next request becomes more precise. We recommend designing the process with the assumption that it will inform future engagements, rather than treating each effort as a one-off.
Success or Failure Is Largely Determined at the List Stage
Based on our experience across numerous projects, the success or failure of a campaign is largely determined at the candidate list stage. This is because the adjustments possible after a post goes live are limited.
What determines list quality is not follower count. Our performance data shows that engagement rates can vary significantly even among influencers with similar follower counts (for details, see How Much Does Engagement Rate Vary Even Within the Same Follower Band?). Building a list based on follower count alone tends to result in actual engagement falling short of expectations.
Another key factor is the overlap between an influencer's audience and the demographic the brand wants to reach. If followers' interests and age group diverge from the brand's target, the post won't reach the intended audience—even if it looks polished. In addition, whether the influencer's own content aesthetic aligns with the brand's aesthetic affects how natural the post feels. When this alignment is off, a post can be completed successfully yet still fail to drive results. For more on why this kind of mismatch occurs, see When a Sponsored Collaboration's Results Don't Add Up.
Only when requirement definition accuracy and careful candidate assessment are both in place can the subsequent negotiation and post direction function effectively. If either is lacking, no amount of careful contracting or post direction can fully recover the results.
Frequently Asked Questions
What's the minimum follower count to request casting?
There's no fixed minimum. What matters more than follower count is overlap with the target audience and the actual level of day-to-day engagement. A candidate with fewer followers but greater audience overlap can sometimes deliver better results than a candidate with more followers but a mismatched audience.
How long does it take from request to posting?
The timeline depends on the scale of the project and the number of candidates. Candidate selection requires time to carefully refine the list, and after selection, further steps follow—negotiation, briefing, and pre/post-publication checks. The more buffer built into the schedule, the more time available to compare and evaluate candidates, which ultimately reduces the risk of mismatches.
How is this different from gifting?
Gifting involves providing a product or service without requiring a post. Even without a posting obligation, our data shows that posts actually occur in many cases (for details, see What Percentage of Gifting Actually Results in a Post?). Influencer casting, on the other hand, formalizes post content and publication timing as a contract. Which approach to use depends on how much certainty is needed.
Can we request multiple influencers at the same time?
Yes. In fact, combining multiple candidates allows you to reach multiple audiences with different follower demographics. As the number of candidates increases, assessing how well each individual's aesthetic aligns with the brand becomes even more important, meaning the accuracy of requirement definition has a greater impact on the quality of the overall list.
