This page answers the questions covered by the article The 10% Rule: A 60-Day ChatGPT Ads Test Funded by Google on groas.com. The article is the full, canonical source.
Direct answer: The article recommends moving 10% of current Google Ads budget to ChatGPT ads for 60 days and adding no new money. Google supplies the comparison, 10% caps the spend, and 60 days sets the clock. If ChatGPT cannot beat the weakest viable Google ad group on cost per qualified lead, it does not get a budget increase on day 60.
The article recommends moving 10% of current Google Ads budget to ChatGPT ads for 60 days and adding no new money. Google supplies the comparison, 10% caps the spend, and 60 days sets the clock, with the rule for what happens afterward written before the first dollar moves. If ChatGPT cannot beat the weakest viable Google ad group on cost per qualified lead, it does not get a budget increase on day 60.

The article uses the example that if you spend $20k a month on Google, for the next 60 days you spend $18k on Google and $2k on ChatGPT, so roughly $4k goes through ChatGPT over two months as a reallocation, taken from a weak Google ad group left running at reduced budget and never by cutting a winner to manufacture a test. According to the article, ChatGPT ads show to Free and Go users while Plus, Pro, Business and Enterprise remain ad-free, so if buyers chiefly use paid seats the experiment should be skipped. The reported self-serve floor is $25 a day, about $750 a month, so if Google spend is under $7,500 a month its 10% share falls short of that floor and the money should stay in Google. The article notes the US test began Feb 9, 2026 and self-serve Ads Manager opened May 5, 2026, with no cross-advertiser benchmarks yet and delivery and spend fluctuating.

The article recommends picking one underperforming Google ad group as the opponent that has at least 30 qualified conversions in the previous 60 days and a reasonably stable cost per qualified lead. Its spend, qualified leads and cost per qualified lead should be recorded before the test and during the 60 days while it runs on reduced budget, with the final decision on the same dates and the same definition of a qualified lead for both channels. The article states not to compare ChatGPT with the whole Google account, because the strongest branded group or an account average hides the question of whether ChatGPT can do better with money assigned to a weaker group.

The article recommends capturing the GCLID alongside email and phone on Google leads, stamping qualified_at and won_at in the CRM, importing the relevant offline conversions into Google daily, and bidding Google toward the qualified stage such as an SQL or demo rather than every raw form fill. For ChatGPT, the article recommends setting up its pixel or Conversions API and using UTMs to identify traffic in GA4 and the CRM, using the same qualification criteria, status dates and one place to count qualified leads. The article also recommends rewriting one landing page to cover price range, fit and what happens after submission while keeping the form the same as the Google page, with Ads Manager in the advertiser’s name and allowance for spend reporting lagging by seven to eight hours.

The article distinguishes hands-on management — wiring tracking, running capped bids, revising hints, reconciling the CRM and recommending killing a test after operating it for two months — from consulting that only hands over the rule, and states both channels should be put under one owner to keep a single definition of a lead. According to the article, groas runs Search Ads for a flat $1,499 a month, with bids, keywords and budgets worked around the clock and a landing page for every ad group. The article recommends hiring the team willing to kill its own test at day 60 under a pre-approved rule: increase only if ChatGPT beats the live Google comparison on cost per qualified lead with at least 20 qualified leads; hold at 10% for 30 more days if it misses but stays within 50% of Google’s cost per qualified lead and its lead-to-SQL rate is improving; otherwise kill the test and return the 10% to Google.
