Downsides of fluct
A Downsides analysis of fluct based on its services and positioning in the digital advertising industry:
1. Primarily Japan-Centric Presence
• Though fluct serves over 5,000 publishers, its core operations and client base are concentrated in Japan and East Asia, limiting global reach compared to major global SSPs, e.g. Google Ad Manager, Magnite, PubMatic.
2. Dependence on Google Ecosystem
• Heavy reliance on Google’s ad-tech ecosystem like AdMob, GCPP certifications, might pose challenges if Google policy changes impact partner programs.
3. Smaller Scale Compared to Global AdTech Giants
• In terms of resources, fluct operates on a smaller scale than global SSP leaders, which may limit its ability to offer ultra-large enterprise-level infrastructure or global demand pool diversity.
4. Limited Visibility in Open Exchange Bidding
• Compared to large global exchanges, fluct’s open exchange bidding presence might be limited, making it more suitable for premium/private marketplace deals rather than broad-scale open RTB.
5. Engineering-Heavy Solutions May Require Strong Publisher Tech Teams
• While fluct offers robust technical support, the depth of their solutions, e.g. Prebid header bidding, may require publishers to have competent in-house tech teams for optimal implementation.
