We've been keeping track of the bots, spiders, OpenAI has been releasing. OpenAI just posted about a new bot for ads, it is named OAI-AdsBot.
It makes sense, now that OpenAI does ads on ChatGPT - it does need a user agent for its ads bot.
OpenAI describes the bot as:
OAI-AdsBot is used to validate the safety of web pages submitted as ads on ChatGPT. When you submit an ad, OpenAI may visit the landing page to ensure it complies with our policies. We may also use content from the landing page to determine when it’s most relevant to show the ad to users. OAI-AdsBot only visits pages submitted as ads, and the data collected by OAI-AdsBot is not used to train generative AI foundation models.
So this bot does:
(1) Validates the safety of the ad's landing page (2) Checks that the landing page complies with its policies (3) Reviews the content of the landing page
Here is the full user-agent string:
Mozilla/5.0 AppleWebKit/537.36 (KHTML, like Gecko); compatible; OAI-AdsBot/1.0; +https://openai.com/adsbot
We've got a new OpenAI crawler and it makes total sense. Meet OAI-Adsbot:
