HONEST ALTERNATIVE · SEO + AI VISIBILITY
SpyFu is a competitor intelligence platform — it shows which keywords competitors rank for organically, which keywords they buy in Google Ads, and historical PPC ad copy. It's strong for competitive research but isn't a site audit tool. DeepSEOAnalysis covers the other side: a free, no-signup technical and AI-visibility audit of your own site — 80+ checks, real CrUX Core Web Vitals, structured data validation, and a GEO score. No trial, no account, shareable via URL.
At a glance
The useful answer is not “which tool is best?” It is which tool fits the job you need done this week.
| Criterion | Competitor | DeepSEOAnalysis |
|---|---|---|
| Free access | SpyFu offers limited free searches (competitor keyword data and PPC research visible without an account, but download and full history require a paid plan). Site auditing is not a free feature. | Complete site audit is free with no signup, no email gate, no daily limit. All check details, severities, and fixes are visible on every crawl. |
| Primary use case | SpyFu is a competitor intelligence tool: reveals which keywords competitors rank for organically, which keywords they buy in Google Ads, and historical PPC ad copy. Strong for competitive keyword and ad research. | DeepSEOAnalysis is an audit-first tool: 80+ technical and on-page checks, real Core Web Vitals from CrUX field data, structured data validation, internal link graph analysis, and AI visibility scoring. |
| AI visibility / GEO | No AI-citation readiness scoring. SpyFu does not check llms.txt presence, AI crawler access, FAQPage schema, or content structure for LLM retrieval. It's a competitive research tool, not an audit or AI-readiness tool. | GEO score covers all five AI visibility signals: AI crawler access, llms.txt, FAQPage/HowTo schema, question-heading ratio, and content chunkability for LLM retrieval. |
| Core Web Vitals | SpyFu does not provide Core Web Vitals data. Its focus is on keyword and PPC competitive intelligence, not technical site performance. | Real Google CrUX field data (actual Chrome users, 28-day aggregate) — not synthetic lab scores. Shows pass/fail against Good/Needs Improvement/Poor thresholds for LCP, INP, and CLS. |
| Shareable reports | SpyFu reports live in the dashboard. Sharing requires exporting to CSV/PDF or sharing account access. Competitor research reports can be exported. | Every audit has a public shareable URL. Paste into a ticket, email, or Slack — no account required to view the full report. |
| Site audit depth | SpyFu is not a site audit tool. It provides competitive keyword research, PPC analysis, and domain overview data — not a crawl-based technical audit of your own site's health. | 80+ checks across six weighted categories: technical (crawlability, redirects, canonicals, HTTPS), onpage (title tags, meta, headings, content), performance (CWV), structured data (JSON-LD validity), links (orphans, anchor text, crawl depth), and AI visibility. |
| Best fit | PPC teams and SEOs who need competitive keyword intelligence: which keywords competitors rank for, what ads they run, historical ad copy, and organic vs. paid competitive landscape. | Developers, founders, and SEO teams who need a complete ungated technical and AI-visibility audit, shareable via URL, with CMS-specific fix instructions and real field data. |

No. SpyFu is a competitive keyword and PPC research platform. It doesn't check llms.txt, AI crawler access (GPTBot, ClaudeBot, PerplexityBot), FAQPage schema, or content structure for AI answer engine retrieval. DeepSEOAnalysis includes a dedicated GEO score covering all five AI visibility signals.
SpyFu is best when you want to research competitors: which keywords they rank for, what ads they run, and how their organic vs. paid presence compares.
