1. Investigación de palabras clave
Ahrefs: The Ahrefs Keywords Explorer lets you generate keyword ideas with search volume, keyword difficulty scores, and traffic potential estimates. You can research keywords across ten search engines including Google, YouTube, and Amazon. The explorer tool also shows search intent and SERP features for each target keyword, helping you conduct keyword research more efficiently.
SpyFu: SpyFu’s keyword research tool focuses on competitor keyword analysis. You can do a keyword search on any domain to see every keyword a competitor ranks for, along with search volume and keyword difficulty. The SpyFu keyword overview automatically groups keywords into topics for easier content planning, helping you find lucrative keywords and related keywords fast.
2. Análisis de backlinks
Ahrefs: The Ahrefs backlink profile tool displays all links pointing to any domain. It tracks referring domains, daily backlink growth, and lost links. The Ahrefs backlink data updates hourly, giving you current information for link building strategies. You can also check how much traffic competitor backlinks send through the Ahrefs Site Explorer tool.
SpyFu: SpyFu includes backlink analysis, but its database is smaller compared to Ahrefs. The Backlink Kombat feature shows links pointing to multiple competitors but not to you. This is useful for finding link building opportunities, though you may need another tool for deep backlink research.
⚠️ Advertencia: SpyFu’s backlink data updates weekly, while Ahrefs updates hourly. If real-time backlink monitoring matters to your SEO campaign, Ahrefs has a clear advantage here.
3. Análisis de la competencia
Ahrefs: The Ahrefs Site Explorer shows any competitor’s organic keywords, top ranking pages, and backlink profile. You can also compare keyword gap data for up to 10 competitors at once. The content explorer helps find what content performs best in any niche, providing actionable SEO data for your SEO campaign.
SpyFu: Competitor research is where SpyFu shines. The Kombat tool uses a Venn diagram to visualize keyword overlaps and gaps between your domain and competitor sites. You can see every keyword competitors target in both organic search and Google Ads campaigns.
4. PPC and Paid Search Research
Ahrefs: Ahrefs provides basic paid search data through its Site Explorer. You can see paid keywords and estimated traffic value. However, its PPC research is not as deep as its organic SEO tools.
SpyFu: PPC analysis is SpyFu’s specialty. It shows every keyword a competitor has bought on Google Ads, their ad copy variations, estimated ad spend, and ad history going back years. The Google Ads Advisor even recommends profitable keywords based on competitor bidding patterns. SpyFu PPC research covers competitors’ PPC campaigns and competitors’ PPC strategies in full detail.
5. Auditoría del sitio y SEO técnico
Ahrefs: The Ahrefs site audit feature crawls your site for broken links, duplicate content, slow pages, and missing meta descriptions. It produces a health score and prioritizes issues by impacto. This makes fixing on-page SEO and page SEO problems straightforward. It is also a valuable keyword tool for reviewing your own website’s SEO performance.
SpyFu: SpyFu does not include a built-in site audit tool. If you need technical SEO crawling and page-level health checks, you’ll need to pair SpyFu with another tool. This is a gap for users who want complete SEO software in one subscription.
6. Seguimiento de clasificación
Ahrefs: The rank tracker monitors organic keyword rankings across different locations. The Lite plan allows tracking up to 750 keywords. Ahrefs lacks device-level tracking, which means you can’t separate mobile from desktop rankings.
SpyFu: SpyFu lets you track keyword rankings over time for both organic and paid keywords. The daily performance tracker monitors weekly ranking changes across major search engines. The Team plan supports up to 40,000 tracked keywords.
7. Reporting and Data Exports
Ahrefs: Ahrefs provides an SEO reporting tool with customizable dashboards. Reports can be exported in various formats. However, the credit-based system means heavy report generation may eat through your monthly allowance faster.
SpyFu: SpyFu generates client-ready reports that combine SEO, PPC, and competitive data in one document. All paid plans include unlimited data exports and unlimited domain overview PDFs on the Professional plan. The SpyFu API gives developers access to raw SEO data for custom reporting. No credit limits apply.

| Nivel medio | $208/mes (Estándar) | 89 $/mes (Pro + IA) |
| Nivel superior | $374/mes (Avanzado) | $187/mes (Equipo/Agencia) |
