What our research says

Ahrefs

Ahrefs is the backlink index most SEO teams treat as the reference, and the rest of the suite — keywords, rank tracking, audits — is strong enough that it usually replaces two or three cheaper tools. The entry prices mislead: Starter at $29 is a taster, and Lite at $129 is a single seat with credit limits, so a small agency lands at Standard plus extra users before it feels unconstrained. Buy it for the data; price it on your real seat count.

Pros

  • Backlink index built on Ahrefs' own crawler, with trillions of links and years of history
  • Keyword research, rank tracking, site audit and AI-answer visibility in one subscription
  • API and MCP access included from the Lite plan, not sold as a separate product
  • Free tier for your own verified sites and a $29 Starter for light use

Cons

  • Lite caps usage at 1,000 credits per user and six months of history
  • Every plan includes one user; additional seats are a per-month surcharge
  • Enterprise at $1,499 requires an annual commitment
  • Brand Radar AI and prompt-check packages are paid add-ons on top of the plan

Similarweb

Similarweb is the incumbent in traffic estimation, and the AI-visibility tracking is a real extension rather than a badge: it measures how often the major chatbots surface your brand, which is becoming its own channel. The pricing is the friction — nothing is self-serve, so you talk to sales before you know the number.

Pros

  • Coverage across websites, apps and retail SKUs
  • AI Search Intelligence tracks citations across six chatbots
  • Documented data API alongside the dashboards
  • Named company with a real headquarters

Cons

  • No published pricing at any tier
  • Traffic figures are modelled estimates, not measured truth
  • Founding year is not stated on the site
