Things advertisers often ask
Practical notes from OpenAI's own Help Center.
What maximum bid should I start with? Official
For CPC campaigns, OpenAI recommends starting with a maximum bid of US$3 to 5 per click. This is OpenAI's figure in US dollars, shown here as stated and not converted to baht.
Why does Ads Manager show zero spend when I think I was charged? Official
Spend in Ads Manager can lag by 7 to 8 hours, so a displayed spend of zero does not mean there are no charges. Impressions, clicks and CTR refresh about every 15 minutes.
Do ad-review crawler visits count as clicks? Official
No. Ad-review crawlers may visit your landing page with tracking parameters, and those visits are not billable clicks.
Do UTM parameters survive the ad click? Official
Yes. UTM parameters on your landing URLs persist on ad clicks, so your own analytics can tell ChatGPT Ads traffic apart.
What does this mean for advertisers in Thailand?
The channel is new in Thailand, so rules, features and credits are still changing. Read the entries above for what was reported and when, then check OpenAI's own pages before you commit budget.
