Ads Lighthouse vs SpyFu in 2026: brand-search evidence vs historical PPC and SEO intelligence

Ads Lighthouse is built around a deliberately small unit of proof: a paid result that appeared for a configured keyword, engine, location, device, and time. A project stores a brand, its domains, markets, devices, keywords, and schedule, then checks Google and Bing text ads. The saved record can include advertiser domain, ad copy, and destination. Growth and higher plans also monitor sponsored Google Shopping product listings. This makes it a practical tool for questions that must be answered with context rather than an aggregate competitive estimate.

The surrounding workflow suits brand protection and affiliate administration. A team can upload known affiliate IDs, match them in saved Google ad links, trace eligible destinations, filter advertiser history, and open policy cases around copy, position, links, or prohibited terms. New and returning advertisers can create email, Slack, or webhook alerts. Observed visibility is carefully bounded as the share of saved monitored searches where a domain appeared. It does not represent Google impression share, purchased-keyword proof, spend, trademark infringement, or a competitor’s commercial outcome.

Starter is $49 monthly for one project, 20 keywords, two locations, 7,500 scheduled checks, and 100 on-demand checks. Growth at $99 adds Google Shopping; Scale at $299 introduces REST API keys and client-branded reports. All plans include exports, roles, alerts, and an MCP server. Ads Lighthouse is compelling when a current external paid-search appearance needs a repeatable record and response path, not when a team needs backlink analysis or an organic keyword gap.

SpyFu begins with a competing domain rather than a configured observation. Its PPC research helps a marketer see ads a domain has run, keywords it targeted, historical campaign patterns, and estimated spend. The SEO side reveals organic keywords, overlap and gaps with a competitor, ranking history, and backlinks. That combination makes SpyFu useful for planning a search strategy, entering a market, or preparing a client landscape analysis, especially when the team needs both paid and organic evidence in one workspace.

The platform adds its own rank tracking, with weekly updates on Basic and 15-minute updates on Pro + AI and Team/Agency. Higher plans also include API access, white-label reports, and AI-powered recommendations. Those features create a clear upgrade path for an agency, though they do not create the Ads Lighthouse compliance layer. SpyFu does not publish configured Google/Bing checks that save a specific location, device, timestamp, destination trace, affiliate ID, and policy case for each observed search appearance.

Basic costs $39 per month and is the low-cost entry for competitive keyword work. Pro + AI costs $119 and Team/Agency costs $249; both add API access, white-label reports, and 15-minute rank updates. SpyFu’s historical ad data and estimated spend should be used as strategic clues, not as verified advertiser economics. Buy it for domain-level research across PPC and SEO. Do not buy it when a current brand-search event requires a dated evidence pack or a documented affiliate-compliance process.
