Google has raised the required minimum traffic limit for publishers who wish to use its AdSense API to 100,000 page views per day. The AdSense API was introduced in March as a way for sites with user generated content to share advertising revenue with their members. Says Google, "This policy change will probably result in fewer developers going live and give us a chance to enhance our support resources and processes to more easily support a greater number of developers in the future...we hope to be able to lower it in the future as we become more efficient at supporting our developers!" Meanwhile, some publishers report waiting a month for their API usage to be approved. I take Google at its word for now but worry that small developers could be increasingly squeezed out of the mashup space if this were to become a trend.
