Semrush vs SpyFu: pricing, features and which to choose

Semrush is a brand visibility platform made by Semrush, now an Adobe company. The company says it has spent more than 17 years helping marketers scale and grow, which places its founding around 2008, although the cited product pages do not identify a separate launch year for the product. Its core work covers keyword research, competitor analysis, backlink data, rank tracking, technical site audits, content, paid media, social marketing, local search, and AI search visibility. Adobe completed its acquisition on April 28, 2026. The company says Semrush is used by more than 28 million users globally, ranging from scaling startups to Fortune 500 companies. The acquisition moves Semrush from a standalone public company into Adobe's customer experience portfolio, while the product remains aimed at marketers and agencies.

A typical Semrush workflow begins with a domain, project, or competitor. Users can discover keywords, compare competing sites, crawl technical problems, track positions, generate content guidance, and assemble reports for colleagues or clients. The current plans combine SEO with AI visibility, while specialist toolkits cover traffic and market analysis, local marketing, content, social, advertising, and AI public relations. AI visibility features track brand appearances, sentiment, and competitors across Google Search, ChatGPT, Perplexity, and Gemini. Starter includes MCP access and an AI-ready Site Audit. Pro+ adds historical SEO data, content optimization, keyword cannibalization analysis, multi-location tracking, and device tracking. Advanced adds API access, SEO Share of Voice, and deeper automation. Reports can combine Semrush data with Google Analytics and Google Search Console.

Semrush's breadth comes with quotas, separate toolkit purchases, and a configuration burden that may exceed the needs of a small business seeking a basic rank tracker. Its search and AI visibility figures are measurement products, not first-party analytics, and AI appearances cannot guarantee conversions. Ahrefs is a strong alternative for backlink and keyword analysis, Moz Pro focuses on established SEO workflows, and Similarweb emphasizes traffic, audience, and market estimates. Semrush is the better fit for agencies and marketing teams that need SEO, AI visibility, reporting, and specialist tools in one account. Buyers should pick it when cross-channel visibility matters more than a narrow, lower-cost SEO tool.

SpyFu is a search marketing research tool based in Scottsdale, Arizona, founded by Mike Roberts and built on keyword data he began collecting in 2005. Its long history is the main selling point: SpyFu says it stores more than 10 years of ranking and ad data per domain, and its marketing cites 18-plus years of keyword history. It sits in the same category as Semrush and Ahrefs but costs much less and focuses more on paid search. A user types a competitor's domain and sees the keywords it ranks for organically, the keywords it bids on in Google Ads, the ad copy it has tested over time and estimates of monthly clicks and spend.

Most sessions start with a domain search. The overview shows organic and paid keyword counts, estimated traffic value and top competitors. From there, users drill into the most profitable paid keywords, ad history showing every ad variation a competitor has run, and Kombat, which compares up to three domains to find keywords the others share and you lack. Keyword research covers volume, difficulty, cost per click and related questions. Backlink search, rank tracking, automated reports and a Google Ads Advisor that suggests keywords to buy round out the tool. A Site Audit crawler with AI fixes, added in 2026, checks technical SEO and can publish corrections to connected sites.

SpyFu's data is weakest outside the US and UK, and its backlink index is smaller than Ahrefs'. Technical SEO tools are newer and thinner than Semrush's, and the interface feels dated next to newer tools. Semrush covers more channels, including social and local, but starts around $140 a month. Ahrefs has the strongest backlink data, and Similarweb gives better traffic estimates for large sites. SE Ranking offers broad SEO features at a similar price to SpyFu. Pick SpyFu if your priority is seeing competitors' Google Ads keywords and ad tests over many years for little money; pick Semrush or Ahrefs for full SEO programs.
