[Background] The difficulty of choosing a YouTube advertising agency is increasing year by year
The number of domestic YouTube users in Japan has reached over 73.7 million (as of May 2024), making it the second-largest social media platform in the country after LINE (according to Comnico). While the corporate use of YouTube advertising is rapidly expanding, the number of operation proxy agencies is also surging, resulting in significant variations in quality, pricing, and areas of expertise.
Furthermore, YouTube advertising is an area requiring complex, specialized knowledge, including targeting design, creative production, data analysis, and bidding strategies. Choosing the wrong agency not only wastes advertising budgets but can also risk damaging the brand image.
As a result, failure cases like the following are not uncommon:
- Discovering a lack of skill in the assigned representative after contracting, leading to the contract period ending without achieving results.
- Requesting a major agency, but experiencing slow responses because the company's budget size is given a low priority.
- Requesting video production and ad operation from separate companies, leading to bloated costs due to poor coordination.
- Continuously paying higher-than-market rates due to a lack of knowledge about standard pricing.
- Hiring a company that doesn't fit the firm's challenges due to a lack of understanding of categories (e.g., major comprehensive type / video production specialized type / analytical SaaS linked type).
Many of these failures are caused by a lack of information and comparison before making a request. Therefore, an objective source of information that organizes the characteristics, areas of expertise, and price ranges of agencies prior to requesting is necessary.
▼ Main challenges faced by companies
- Want to start YouTube advertising but cannot determine which company to hire.
- Not seeing results with the currently contracted agency and considering switching.
- Looking for a company that can handle both ad operations and video production in one package.
- Want organized information on differences in market prices and scopes of work.
- Want to know agencies with proven track records tailored to the company's industry and objectives (e.g., brand awareness, CV acquisition, EC).
[Characteristics of the Chaos Map]
This chaos map classifies 38 major companies in YouTube ad operations into the following 6 categories:
1. Major Ad Agencies & Comprehensive Digital Agencies (9 companies)

A category gathering comprehensive digital agencies with top-class scale and track records in Japan, such as CyberAgent, dentsu, DENTSU DIGITAL, Hakuhodo DY ONE, Hakuhodo DY holdings, SEPTENI, ADK, ADWAYS, and Members. Their strengths lie in capabilities for DCG (Dynamic Creative Generation) and full-funnel marketing, but if the monthly budget is small, the priority given by representatives may decrease.
2. Video/SNS Ad Operation Specialists (4 companies)
→ Consider this when valuing expertise in YouTube/SNS ads and focusing on operational quality.
A category of specialized companies focusing on video and SNS ad operations, such as CyberBuzz, Allied Architects, Full Speed, and Trenders. Armed with deep knowledge of specific media and the latest operational know-how, they feature a high likelihood of producing strong results in campaigns aimed at acquiring conversions.
3. MCN & Creator-Based (7 companies)
→ Consider this when planning ad and UGC campaigns utilizing influencers and creators.
A category of companies executing YouTube ad campaigns based on MCN (Multi-Channel Network) and creator management, such as BitStar, Natee, THECOO, #GROVE, Kiii, VAZ, and pamxy. They have strengths in tie-up ads with creators and promotions leveraging natural virality on social media.
4. Video Production x Ad Operation Integration (6 companies)
→ Consider this when wanting to request everything consistently from video production to ad operations.
A category gathering companies that balance creative production capabilities with ad operational capabilities, such as LOCUS, PROOX, RICHKA, VideoBRAIN, Somethingfun!, and AIR Design. They solve issues like 'We can make videos but don't know how to operate them' or 'We can place ads but creative testing is slow.'
