Three platforms, three different histories

Each history has a vertical timeline. Every milestone opens a separate page explaining the change and what it means when you compare subscriptions.

  1. Semrush History:
    From One Tool to Adobe

    Semrush began in 2008 and became an Adobe company in 2026. Follow the changes that explain its broader product range and the subscription decisions buyers face today.

  2. Ahrefs History:
    From Web Data to AI Visibility

    Ahrefs began in 2010 and expanded from web research into free site tools and AI-mention reporting. Follow the dates that changed what buyers could do with an account.

  3. Moz History:
    From SEOmoz to AI Visibility Partnerships

    Moz began as SEOmoz in 2004. Its history explains the name change and authority scores, then follows the company into its 2026 data partnership with Profound.

The company story can change the buying decision

A subscription can outlive the reason you first bought it. The platform grows and the team keeps renewing, even when nobody has revisited which parts are doing real work.

These histories give that review a starting point. Semrush's Adobe acquisition raises ownership and agreement questions. Ahrefs' free-access milestone helps separate work on your own site from broader research. Moz's metric changes explain why a score can move without a matching change in the business.

The stories stay connected to the purchase: Ahrefs versus Semrush, pricing and team costs and Moz Pro alternatives.
