Ads Lighthouse vs Metistic in 2026: brand-search monitoring vs ChatGPT ad tracking

Ads Lighthouse is built for a defined brand-search monitoring project. A project combines one brand, its domains, configured keywords, markets, devices, and schedule, then checks Google and Bing paid text ads. Growth and above also capture sponsored Google Shopping listings. Every saved observation belongs to a keyword, location, device, source, and point in time. That structure is valuable when a team needs to answer a concrete compliance question with a record, rather than relying on a one-off search screenshot.

The investigation tools go further than a generic advertiser feed. Paid Results groups observed domains and supports advertiser, keyword, copy-change, and destination drilldowns. Affiliate managers can declare known URL parameters and IDs, surface unfamiliar IDs, and move findings through cases. Policy rules can assess saved copy, position, and destinations, while redirect traces can record status codes, final pages, affiliate identifiers, and an archive when a trace reaches a server. An observation proves an ad appeared in the monitored check, not the keyword bought, spend, or a trademark violation.

Starter is $49 per month for one project, 20 keywords, two locations, daily checks, 7,500 scheduled checks, and 100 on-demand checks. Growth is $99 and adds Shopping and six-hour checks. Scale is $299, adds API keys and agency-branded PDFs, and permits two-hour checks. Every plan includes CSV and Excel exports plus member and admin roles. It is the stronger tool for Google or Bing brand protection, but it does not monitor ChatGPT paid placements or offer a view of paid AI answers.

Metistic is a specialist for a different paid surface. A customer chooses its website, a supported market, and commercial prompts to track; Metistic then runs daily checks and records whether the brand appeared in a paid placement, which advertisers appeared, the creative, and where the brand was absent. The product keeps completed-check counts alongside its percentages. That boundary matters: its figures report a controlled sample of prompts, markets, and dates, not all ChatGPT users or the entire ChatGPT ad market.

Its clearest analytical contribution is separating two forms of absence. An ad gap is a selected tracked result where a competitor appeared and the customer did not, with supporting creative and advertiser context. “No ads seen” means no paid placement was recorded in the selected checks. The product also preserves headline, copy, destination, market, and tracking date for recorded competitors. Starter and Growth expose competitor product ads, the price ChatGPT displayed, and historical changes, which makes it practical for a recurring paid-AI review rather than a single generic score.

Free supports 10 prompts in one market with 30 days of history. Starter is $79 per month for 50 prompts in one of 53 markets, daily tracking, full history, alerts, CSV exports, and competitor product-price visibility. Growth is $299 per month for 200 prompts across any combination of the supported markets and adds scheduled PDFs. Metistic does not run campaigns, monitor Google or Bing brand terms, or file affiliate cases. It is for learning from observed ChatGPT placements, then taking that evidence into a separate advertising workflow.
