Ads Lighthouse vs Google Ads Transparency Center in 2026: Scheduled brand monitoring vs Google’s public ad lookup

Ads Lighthouse turns a defined set of brand-search questions into recurring observations. A project holds a brand, domains, keywords, locations, devices, and schedule. Every check is specific to a keyword, location, device, and source at one time, which creates useful context for a later case or client report. Paid Results groups domains found on those checks and keeps advertiser, keyword, copy-change, and destination drilldowns. Observed visibility is the share of saved monitored searches in which a domain appeared, not Google impression share or a measure of spend.

The product has a workflow layer that a public lookup does not. Affiliate URL parameters and known IDs can be added for matching, with unfamiliar IDs left visible. A user can open and track policy cases for forbidden terms, direct linking, promo codes, or unauthorised IDs. Eligible server-side traces save status codes, final pages, affiliate IDs, and a WARC archive when possible. Alerts can go to email, Slack incoming webhook, or webhook JSON POST for new or returning advertisers, brand mentions, and affiliate markers. Tables export to CSV or Excel, and every plan has PDF reports.

Starter begins at $49 per month for one project, 20 keywords, two locations, daily checks, 7,500 scheduled checks, and 100 on-demand checks. Growth starts Shopping monitoring. Scale at $299 adds API keys, REST API access, and agency-branded PDFs, while the hosted MCP server is offered on every plan. It is most valuable when a team will act on a monitored record over time, rather than conduct a single public lookup.

Google Ads Transparency Center is a public Google search surface, not a paid intelligence subscription. It supports advertiser-name and website searches, which is useful when a researcher knows the destination domain but not the account behind it. A website result may reveal multiple advertiser accounts pointing ads at that domain, and Google says users can narrow the result to an individual advertiser. It is the sensible first stop for verifying what Google makes publicly available before treating a third-party collection as a full record.

The coverage has boundaries that should be stated plainly. Google says represented ads were shown at least once across Search, Display, YouTube, and DV360 in supported formats. An observed record is evidence of public availability through Google, not spend, return, audience size, targeting, or commercial success. A platform filter includes only ads shown since September 4, 2023, so it cannot be read as a full history. Europe and Türkiye can expose extra transparency information, while political ads have a dedicated report where election creative remains available for seven years after the last impression.

Google publishes no self-serve plans, team allowances, alert rules, client reporting, saved boards, or API-style research workflow for the Center. That is not a defect in a public transparency product, but it defines the buying boundary: use it for a free first-party lookup and regulatory context, then add monitoring software only when you need scheduled observations, organisation, notification, or a deliverable for a client.
