Semrush vs SpyFu in 2026: Full-suite platform vs affordable PPC and SEO competitor intelligence
Semrush covers keyword research, technical audits, AI visibility, and agency reporting in one large subscription. SpyFu does one thing narrower and cheaper: uncover exactly what competitors rank for and advertise on, going back years.
Semrush
SpyFu- Semrush tracks AI visibility across ChatGPT, Gemini, Perplexity, Google AI Overviews, and Google AI Mode. SpyFu has no AI model tracking of any kind.
- SpyFu's signature feature is historical PPC ad data going back years, letting teams see how competitor ad campaigns have evolved. Semrush does not offer this level of historical ad intelligence.
- SpyFu updates rank tracking as frequently as every 15 minutes on Pro + AI and above. Semrush does not publish a comparable update frequency.
- Semrush starts at $139.95/mo for Pro with no AI tracking, rising to $249.95/mo for Guru to unlock it. SpyFu starts at $39/mo and its AI-assisted recommendations arrive at $119/mo.
- Semrush has a genuinely usable free tier (10 searches/day, 10 tracked keywords). SpyFu has no free tier; Basic at $39/mo is the entry point.
- Both platforms offer white-label reporting and API access, but Semrush reserves both for its top Business tier at $499.95/mo, while SpyFu unlocks both starting at $119/mo on Pro + AI.
- Semrush's keyword and backlink databases are larger than SpyFu's, making it the stronger choice for broad or long-tail keyword discovery.
Semrush and SpyFu both start from competitor keyword data, but they diverge fast from there. Semrush wraps that data into a full SEO suite: technical audits, backlink analysis, content tools, and AI visibility tracking across five engines, at a price that climbs quickly once you need the AI or white-label layers. SpyFu stays narrow and cheap, leaning hard into historical PPC intelligence and 15-minute rank updates, without ever adding AI model tracking or deep technical auditing. If your team needs one platform to run the entire SEO and AI visibility programme, Semrush is built for that. If your priority is fast, affordable competitive research for both SEO and paid search, SpyFu gets you there for a fraction of the cost.
The tools at a glance
Semrush
All-in-one SEO and AI visibility platform with keyword research, technical audits, and brand monitoring across five LLM engines
Semrush covers keyword research, technical site audits, backlink analysis, and AI visibility tracking across five engines in a single subscription. Its keyword database spans billions of terms across 140 countries, and the technical audit surfaces more than 140 issue types on a recurring schedule.
The AI visibility module, covering ChatGPT, Gemini, Perplexity, Google AI Overviews, and Google AI Mode, requires the Guru plan at $249.95/mo or above. White-label reporting and API access are reserved for Business at $499.95/mo, meaning a full-featured setup with AI tracking, white-label delivery, and API access costs meaningfully more than SpyFu's top tier.
What Semrush does not offer is SpyFu's depth of historical PPC ad intelligence. Semrush's paid search data exists, but SpyFu's multi-year ad history and 15-minute rank refresh are not something Semrush competes on directly.

SpyFu
Competitive intelligence for SEO and PPC with 15-minute rank updates and historical ad data
SpyFu specializes in competitive intelligence: seeing exactly which keywords a competitor ranks for, which ads they run, how long they have run them, and their estimated spend, with historical records going back years. This depth is what sets it apart from general-purpose SEO suites.
Rank tracking updates as frequently as every 15 minutes on Pro + AI and above, considerably faster than most competitors that refresh daily or weekly. The Pro + AI plan also adds a ChatGPT integration for AI-powered recommendations layered on top of the raw ranking and keyword data.
SpyFu does not track AI model visibility at all, and its keyword database is smaller than Semrush's. There is also no deep technical site audit comparable to Semrush's 140-plus issue-type crawler. For teams whose core need is competitive PPC and SEO research rather than a full platform, this narrower scope is a deliberate trade-off that keeps the price down.
| Feature | Basic $39/month | Pro + AI $119/month | Team/Agency $249/month |
|---|---|---|---|
| API access | ✗ | ✓ | ✓ |
| White-label reports | ✗ | ✓ | ✓ |
| Rank tracking updates | Weekly | 15 min | 15 min |
| AI-powered recommendations | ✗ | ✓ | ✓ |

Considering AI Peekaboo alongside Semrush and SpyFu?
Semrush gates AI visibility tracking behind its $249.95/mo Guru plan, and SpyFu has no AI model tracking at any tier. AI Peekaboo tracks AI visibility across major LLM engines starting at $50 per month, with a read and write API and white-label reporting included from the entry plan. For teams whose priority is AI search monitoring rather than PPC intelligence or a broad SEO suite, it is a more direct and affordable route than upgrading Semrush to Guru.

SemrushSpyFuSemrushSpyFuSpyFuSemrushThe decision mostly comes down to budget and scope, not feature parity. Semrush is priced for teams that want one platform to cover keyword research, technical health, backlinks, and AI visibility, and are willing to pay for the breadth. SpyFu is priced for teams whose real need is fast, deep competitive intelligence on both SEO and PPC, and who would rather pair it with a specialist AI visibility tool than pay Semrush's Guru premium for a feature they may use lightly.
Bottom line
Choose Semrush if you need a single subscription covering SEO, technical audits, backlinks, and AI visibility tracking, and your budget supports Guru pricing or above. Choose SpyFu if your work is centered on competitive PPC and SEO research and you want fast rank updates and deep historical ad data at a fraction of Semrush's cost. Teams that need both AI visibility and SpyFu-grade competitive depth will likely end up running SpyFu alongside a dedicated AI visibility tool rather than upgrading to Semrush Guru for that one feature.
Frequently asked questions
Does SpyFu track AI visibility the way Semrush does?
No. SpyFu has no AI model or LLM visibility tracking at any plan tier. Semrush tracks brand visibility across ChatGPT, Gemini, Perplexity, Google AI Overviews, and Google AI Mode, but only on its Guru plan ($249.95/mo) and above.
Is SpyFu cheaper than Semrush for competitive research?
Yes, considerably. SpyFu's Basic plan starts at $39/month and its Pro + AI plan with API access and white-label reports is $119/month. Semrush's equivalent capability, including AI visibility tracking, requires Guru at $249.95/month, and white-label reporting is reserved for Business at $499.95/month.
Which tool has better historical PPC ad data, Semrush or SpyFu?
SpyFu. Its historical PPC ad database going back years is the platform's signature feature, showing exactly which ads a competitor has run and how campaigns evolved over time. Semrush covers paid search intelligence as part of its broader platform but does not compete on this specific historical depth.
Can SpyFu replace Semrush for technical SEO audits?
No. SpyFu does not include a dedicated technical site audit tool, while Semrush crawls sites for more than 140 issue types including broken links, duplicate content, and crawlability problems. Teams needing technical audits alongside competitive research will need Semrush or a separate audit tool.
Is SpyFu worth it for a freelance SEO consultant in 2026?
Yes, for most freelance consultants doing competitive keyword and PPC research, SpyFu's $39/month Basic plan covers the core workflow at a fraction of Semrush's Pro price. Consultants who also need AI visibility reporting for clients will need to add a dedicated AI tracking tool, since SpyFu does not offer it at any tier.
