Google To Open The AdSense Gates To Other Ad Networks — That They Approve Of
That They Approve Of — In what looks to be an effort to be the one overall ad network that rules them all, Google sent out an email to AdSense publishers today letting them know that they would soon be opening up their accounts …
Context & Ripple Effects
AdSense has been a walled garden since launch, and Google's recent moves all pushed in the direction of extending its reach rather than opening it: YouTube videos entered the AdSense inventory pool in October 2007, followed days later by AdSense placements inside Facebook apps. The pattern was consistent — Google using its publisher base to place more kinds of ads, not to admit rivals.
This announcement reverses the exclusivity half of that equation while keeping the control half intact: third-party ad networks will be able to compete for AdSense publishers' inventory, but only after passing Google's approval process. The gate stays shut; Google just starts deciding who gets through.
First-order effects
- Third-party ad networks gain a path into one of the web's largest publisher inventories — provided they clear Google's vetting, which turns an application decision into a competitive filter.
- AdSense publishers get additional demand sources bidding for their ad space, with Google still operating the account relationship and taking its position in the flow.
Second-order effects
- Rival networks now have to optimize for two audiences at once — advertisers and Google's approvers — meaning Google's quality bar effectively becomes an industry standard set unilaterally by its largest competitor.
- Networks that fail or decline approval are pushed back onto smaller publisher bases, concentrating premium long-tail inventory further under Google's roof even as it admits rivals onto it.
Third-order effects
- If the model holds, dominant platforms shift from excluding competitors outright to charging them admission in kind — control over standards, data visibility, and approval criteria replaces ownership of the whole pipeline as the source of leverage.
- An intermediary that hosts its own rivals becomes harder to displace and, over time, a likelier target for scrutiny from publishers and regulators asking who benefits from the rules of the gate.
The trend: Distribution gatekeepers are learning that controlled openness — admitting rivals under your own approval regime — defends dominance better than closing the gates ever did.
