This page answers the questions covered by the article The $1,000 ChatGPT Ads Test: When the Management Fee Costs More Than the Media on groas.com. The article is the full, canonical source.
Direct answer: According to groas, at $1,000 a month in ChatGPT ad spend its $1,499 Search Ads fee is about 150% of media for a $2,499 total test. At an illustrative $4 per click inside the $3 to $5 starting-bid range, $1,000 buys about 250 clicks, which at 2% conversion is five conversions. The article recommends funding the sample the expected CPA requires, fixing tracking first, and hiring management only when the budget can plausibly buy 30 conversions.
The article recommends no agency for a small-budget test under $2,500 and advises running one campaign at the $25 daily floor or waiting until a more readable sample can be funded. According to groas, under $2,500 for leads or demos, six expected conversions do not justify a management fee. A report saying more data is needed does not improve because an advertiser paid someone to produce it.

The article states it would not pay anyone, including groas, to manage a sample too small to settle the channel question. According to groas, managed testing should be considered only when the budget can plausibly buy 30 conversions and the fee fits the total test cost. At $5,000 or more with a matched page and a plausible $150 CPA or lower, the article describes a managed test as having a reasonable shot at a directional read.

According to groas, at $1,000 in media the $1,499 fee takes 60% of the total $2,499 outlay and is about 150% of the media budget. At an illustrative $4 per click, $1,000 buys about 250 clicks, which at 2% conversion is five conversions. The article states that five tells an advertiser that someone bought or enquired but does not tell whether the channel works.

For this planning exercise the article uses 30 to 50 conversions as the point where a small test starts to speak, described as a directional reading threshold and not a guarantee of significance. Published Google Ads experiment guidance discussed in the article mentions 50 to 100 goal completions for a more reliable comparison, with a 15-conversion minimum and 30 or more recommended for Target CPA stability. The article notes that if 10 demo requests become 12 at the same spend, reported CPA falls by about 17%, which may reflect a small sample wobble.

The article recommends setting the budget from expected conversions by multiplying an honest CPA by 30, so a $150 CPA calls for $4,500 in media and a $400 demo calls for $12,000. It recommends running one campaign for four weeks with one prompt cluster, one matched landing page and one primary conversion event, then reviewing week four against the organic baseline. Counting must be fixed before raising spend by using Pixel and Conversions API with a shared event ID and intact attribution parameter, with no scale until conversions deduplicate.
