ChatGPT competitor ad research: a 6-step workflow

ChatGPT competitor ad research is the process of identifying which brands advertise inside ChatGPT in your niche, what prompts trigger their placements, and where the channel is still open. The advertiser library is the fastest starting point: it catalogs every brand we have observed buying placements inside ChatGPT, filterable by niche, placement volume, and triggering prompt. The rest of this guide walks through a six-step workflow using real data from the advertisers and prompts we track.

What is ChatGPT ad research, and why does it matter?

ChatGPT ads are sponsored placements that appear inside ChatGPT's conversational answers when a user asks a question related to a brand's product or service. They look different from Google search ads. Instead of bidding on a keyword, advertisers buy against the intent behind a natural language prompt. That makes competitor research both more useful and more opaque than a traditional keyword sweep like the ones you would run in SEMrush or Google Ads reports. You cannot see a competitor's bid strategy, but you can see exactly when their ad appears and what question triggered it, which is a richer signal than a keyword report.

Step 1: Browse the advertiser library

The fastest way to map the competitive landscape is the advertiser library. It lists every brand we have observed buying ChatGPT ads, sorted by total placements. Skim the top of the list first: those are the brands with the largest commitment to the channel. Then narrow down to the advertisers active in your category, because a fintech giant showing up for SaaS prompts is interesting, but a SaaS rival showing up for your exact prompts is actionable.

Step 2: Identify the top spenders

Placement count is the best proxy we have for spend, because there is no public auction or pricing data from the channel. A brand running 3,000 placements a month is clearly more committed than one running 300. Use the advertiser directory to see who is dominating the channel overall, then check each one's dedicated profile, like Mastercard's, for the niche breakdown and prompt history.

Step 3: Map your niche

Each niche has its own competitive set, and the niche directory tells you how crowded yours is. Enterprise & Fintech leads the channel with 2,562 placements split across 895 advertisers. SaaS & Productivity is close behind at 2,126 placements across 786 advertisers. The mix of placements and advertisers tells you whether your niche is concentrated or fragmented, and that changes your strategy.

Read the rightmost column as a concentration signal. A high number means a small set of advertisers splits most of the placements, which is a concentrated market. Eyewear & Glasses has just 6 advertisers sharing 38 placements, an average of 6.3 per brand, so the top players have already locked in the channel. Real Estate is the opposite: 617 advertisers chasing 1,288 placements averages 2.1 per brand, which means the niche is fragmented and a focused new entrant can still grab share.

Step 4: Reverse-engineer the triggering prompts

This is the part most competitor research misses. ChatGPT ads are matched to the intent behind a prompt, so if you can see which prompts trigger a competitor, you can infer which user questions they care about. The mechanism is concrete: every advertiser profile lists the specific prompts we have observed triggering that brand's ads, and the niche-level prompt feed aggregates those prompts across every advertiser in the category. Run the prompts that trigger your top three competitors in a fresh ChatGPT session, and you will see the same ads appear, which confirms the targeting and reveals the language your customers actually use.

Step 5: Drill into advertiser profiles

Every advertiser in the library has a profile page that shows their niche footprint, monthly placement volume, and the prompts we have observed triggering their ads. For example, Mastercard leads the channel with 3,490 tracked placements, while Cloudflare follows at 2,633 placements. Monday.com and Salesforce rank third and fourth at 2,368 and 1,757 placements respectively. Clicking through reveals exactly which questions each competitor is paying to answer, and which ones they are leaving on the table.

Step 5b: Read the three signals in a profile

Three signals matter most. First, commitment level. A competitor at the top of the placement leaderboard, like Cloudflare at 2,633 placements or Aikido Security at 1,478, has clearly committed to the channel and is likely defending their position. Lower-volume advertisers are easier to displace. Second, prompt diversity. A competitor running ads against many distinct prompts is casting a wide net across a category, while one running ads against a handful of specific prompts has narrowed in on a clear use case. Third, recency. A competitor that appeared in our logs last week is new to the channel, and new entrants are usually testing before scaling. Catching a test is cheaper than catching a scale-up.

Step 6: Monitor over time

ChatGPT advertising is moving fast. New advertisers enter the channel every week, and incumbents shift their niche mix as their strategy evolves. A snapshot from last month is already stale. The paid intelligence tier tracks these changes continuously, flagging new entrants in your niche and shifts in any competitor's placement volume. If you are serious about competing in ChatGPT ads, you need a feed, not a one-time pull.

Cadence and ownership

The full workflow takes about 30 minutes per week if you own it inside your growth or SEO team. Assign one owner, schedule a recurring slot, and store findings in a shared doc with the prompt, the competitor, and the date you observed the ad. The brands winning ChatGPT ads today are the ones who started watching six months ago, not the ones who just started.
