How we estimate this

Assumptions

  • Free → paid conversion. 0.5%–2% of active installs pay for the pro tier. Typical for freemium WordPress plugins; the real rate varies a lot by product. Past 1M installs we taper the rate down: a giant free plugin’s long tail converts far worse.
  • Annual price per customer. $99–$199 a year, typical for Security plugins rather than this plugin's own pricing.
  • Acquisition multiple. 2x–4x annual revenue, the going range for small WordPress-plugin businesses, the typical range for a steady plugin.
  • Install base. 5M–6M active installs, from our install estimate (wp.org only publishes the floor).

Revenue is installs × conversion × price; value is revenue × a typical acquisition multiple. Every factor is an assumption band, so the output is a wide range on purpose. If you're buying or selling, treat this as a starting point for due diligence.

Reviewers say Akismet blocks spam automatically with barely any setup, though a few flag pricing and unclear free-tier limits.

    Blocks thousands of fake comments daily. It’s a lifesaver cz my site stays clean without any effort. Setup is super easy too. Only 4 stars coz the pricing for biz sites is a bit high, but thx for the peace of mind!

    It blocks many spam comments, which is helpful. But a few still pass through, and sometimes real comments look suspicious too. Good plugin, just not perfect.

    It catches many spam comments, so my comment section stays cleaner. But sometimes I still need to check things manually. Good support, just not fully hands-free.

    It catches most spam comments for me, which saves time. Setup was simple too. A few things can still slip in, but overall it does the job well.
