Key takeaways
  • SpyFu starts at $39 per month for PPC and SEO intelligence; Pro + AI is $119 per month and adds API access, white-label reports, 15-minute rank updates, and AI-powered recommendations.
  • Gauge Chat Growth is listed at $599 per month and is built around AI visibility, workspace prompt runs, content work, and observed ChatGPT placements.
  • SpyFu documents historical competitor PPC ads, targeted keywords, estimated spend, SEO keyword gaps, backlinks, and Google rank tracking. It does not include AI model visibility tracking.
  • Gauge can connect an OpenAI Ads account and report its owner’s budget, spend, impressions, clicks, CTR, and CPC. Competitor ChatGPT observations do not expose private bids, targeting, total spend, clicks, or CTR.
  • SpyFu Pro + AI and Team/Agency list white-label reports, while Gauge Growth lists three users and does not publish that same report-delivery feature in its reviewed pricing table.
  • Gauge and SpyFu can sit together in a search programme: SpyFu for Google search intelligence, Gauge for selected AI-answer and ChatGPT paid questions.

SpyFu is the sensible default for traditional Google PPC and SEO competitor research. Its historic keyword and ad records, rank tracking, and agency-ready reports solve a familiar search-marketing job at a modest price. Gauge earns consideration when the team’s commercial questions have moved into ChatGPT and need to tie observed sponsored placements to AI visibility and owned OpenAI Ads performance. Neither covers the other’s central evidence source. SpyFu does not track brand presence in LLM answers, and Gauge’s ChatGPT observations are not a replacement for SpyFu’s historic Google PPC and keyword intelligence. Treat this as a channel decision first, then a workflow decision, rather than expecting one subscription to answer every search question.

Gauge

AI visibility and observed ChatGPT ad intelligence for prompt-led growth teams

Full review →
Gauge screenshot

Gauge Chat runs selected prompts and records brand mentions, citations, competitors, and sponsored placements it observes in ChatGPT responses. A marketer can see advertiser names, observed copy, appearance counts, and the buyer questions associated with a placement. This lets a team investigate whether a commercial AI-answer problem calls for content, a paid test, or both.

A connected OpenAI Ads key adds first-party campaign, ad-group, and ad metrics such as budget, spend, impressions, clicks, CTR, and CPC. The wider product includes an Action Center, content workflow, and documented connections for Search Console, GA4, Google Ads, Webflow, Framer, Sanity, and GitHub. It is intended to coordinate growth work, not simply return a historical keyword report.

Chat Growth is listed at $599 monthly, with 600 prompts daily, 54,000 answers monthly, 18 articles, and three users. That price only makes sense if its prompt, content, and paid workflow are used. Gauge does not claim to expose competitor Google campaign history, keyword bids, or SEO rank data in the way a classic PPC intelligence product does.

SpyFu

Google PPC and SEO competitive intelligence with historical keyword and ad research

Full review →
SpyFu screenshot

SpyFu focuses on the traditional search-marketing intelligence job. It documents competitor PPC ads, the keywords associated with those campaigns, estimated spend, and campaign history, alongside organic keyword research, keyword-gap analysis, rank tracking, and backlinks. That makes it useful when a team needs to understand a competitor’s Google search strategy rather than its presence in AI-generated answers.

The Pro + AI plan adds a ChatGPT integration that creates recommendations from SpyFu’s keyword and competitor data, but that is not AI model visibility monitoring. SpyFu’s profile explicitly says it does not track brands in ChatGPT or Gemini answers. Its 15-minute rank updates are also a Google search-ranking function, not a measurement of AI-answer placement.

Basic is listed at $39 monthly, Pro + AI at $119, and Team/Agency at $249. API access, white-label reports, and 15-minute updates begin on Pro + AI, while Basic has weekly updates and one user. That makes SpyFu the more accessible commercial choice for agencies and search teams that need historical PPC and SEO research.

SpyFu wins for Google PPC and SEO intelligence because that is its core product and its $39 starting price fits that job. Gauge wins only when the question is about AI-answer visibility and observed ChatGPT placements, particularly if a team also wants its own OpenAI Ads metrics and content follow-up in the same place. Their overlap is commercial research, not their data set. A company operating across Google and ChatGPT can use both without duplicating the central work of either.

Bottom line

Buy SpyFu for competitor keyword history, Google PPC research, rank tracking, and white-label reports from Pro + AI. Buy Gauge when commercial prompt monitoring and ChatGPT advertising form a recurring growth loop worth $599 per month. Do not interpret SpyFu’s ChatGPT recommendations as LLM visibility tracking, and do not interpret Gauge’s observed ChatGPT ads as a historic Google PPC database. They answer different channel questions, and a mixed-channel team can keep both evidence sets distinct.

Frequently asked questions

Should I choose Gauge or SpyFu for competitor Google Ads research in 2026?

SpyFu is the better choice for competitor Google Ads research because it focuses on historical PPC ads, targeted keywords, estimated spend, and campaign evolution. Gauge’s paid-ad evidence concerns sponsored ChatGPT placements observed from its own workspace prompt runs.

Can SpyFu track whether a brand appears in ChatGPT or Gemini answers?

SpyFu cannot track brand visibility in ChatGPT, Gemini, or other AI-model answers according to its reviewed profile. SpyFu’s Pro + AI plan uses a ChatGPT integration for recommendations based on its search data, which is different from monitoring LLM answers.

Which tool gives an agency white-label client reports for PPC and SEO?

SpyFu gives agencies white-label reports on Pro + AI and Team/Agency plans. Gauge’s reviewed Growth pricing lists three users and its AI-search workflow, but it does not publish the same white-label report feature in that table, so SpyFu is the supported choice for that specific client-delivery need.

Does Gauge show a competitor’s ChatGPT ad budget or targeting?

Gauge does not show a competitor’s private ChatGPT ad budget, targeting, total spend, clicks, or CTR. Gauge can show first-party budget, spend, impressions, clicks, CTR, and CPC when the buyer connects its own OpenAI Ads account, which should not be confused with competitor campaign data.

Can a search team use Gauge and SpyFu together without duplicate work?

A search team can use SpyFu and Gauge together because SpyFu handles Google SEO and PPC intelligence while Gauge handles selected AI-answer prompts, observed ChatGPT placements, and related actions. The products are complementary when both channels matter.
