Serpstat vs SpyFu Comparison 2026
Serpstat runs the full SEO toolkit, keyword research, rank tracking, backlinks, site audits, from $50 a month, or roughly $31 once its annual saving applies. SpyFu answers one narrower question well, what a competitor has ranked for and paid for over more than a decade, from $39 a month, or about $29 annually, and says plainly that site audits and backlink monitoring are the wrong job for it. Serpstat replaces a full SEO platform at a fraction of the market leaders' price. SpyFu goes even narrower and even cheaper, built for competitor research alone.

Serpstat
A full SEO suite at fifty dollars a month
Serpstat does keyword research, rank tracking, backlink analysis and site audits from one account, and prices the entry plan below where the better-known suites start. The data is thinner in some markets than Ahrefs or Semrush, which is the honest trade for the difference. For somebody checking a few hundred keywords a month rather than running an agency, the cheaper tier is not a compromised version of the tool, it is the same tool with lower limits.
Our note
The data is thinner than the market leaders in some regions, and that gap is the whole difference in price. Run the trial against keywords you already know the answer for, because that comparison tells you in an afternoon whether the cheaper tier is enough.
SpyFu
Every keyword a competitor has bought or ranked for
SpyFu is built around one question: what is the other site doing. It keeps more than a decade of history on which keywords a domain ranked for, which ads it ran and what it paid, which is the part the general SEO suites treat as a side feature. For research on a competitor rather than maintenance on your own site, it is the cheaper specialist.
Why people weigh these two
- SpyFu instead of Serpstat
- SpyFu narrows to what a competitor has bought or ranked for specifically, starting at $39 with no free tier, sharper for competitive research than Serpstat's broader audit-to-tracking bundle.
- Serpstat instead of SpyFu
- Serpstat bundles competitor research into a full audit-to-keyword suite for fifty dollars a month by its own tagline, broader than SpyFu's single specialty.
Which one should you pick
Choose Serpstat if the job includes maintaining your own site: audits, rank tracking and backlink checks sit alongside competitor comparison in the same $50-a-month plan. It is not the cheapest option here, but it is the only one of the two that can replace a full SEO platform on its own.
Choose SpyFu if the only real question is what a competitor is doing: $39 a month, or about $29 billed annually, buys more than a decade of their ranked keywords and ad spend, with API access included at that price. It is the cheaper of the two, but it is not a replacement for a full SEO platform, so pair it with a free rank tracker rather than expecting site audits or backlink monitoring from it.
Common questions
- Which is cheaper, Serpstat or SpyFu?
- SpyFu, by a modest margin: $39 a month, or about $29 billed annually, against Serpstat's $50, or roughly $31 annually. The gap narrows once both are billed annually, but SpyFu stays the cheaper of the two either way.
- Can SpyFu run a site audit the way Serpstat can?
- No, it says so directly: anybody needing site audits and backlink monitoring is using the wrong tool. Serpstat covers audits, backlinks, rank tracking and competitor research all in the same subscription.
- How far back does SpyFu's competitor history go, compared with Serpstat's?
- SpyFu keeps more than a decade of history on what a domain ranked for and which ads it ran. Serpstat's competitor comparison is more current-focused, part of a broader toolkit rather than a historical archive going back years.
- Does Serpstat's entry plan include API access?
- No, API credits are unavailable on Serpstat's Individual plan, arriving only on Team and above. SpyFu includes API access on its $39 Basic plan already, which is unusual for the price.
