Semrush One is built for tracking, and the limits show it. Plans cap tracked keywords and prompts: the SEO plan allows 500 keywords, Pro+ allows 1,500 keywords and 100 prompts, and Advanced allows 5,000 keywords and 200 prompts. Historical data and multi-location tracking sit on the upper tiers, and paid access only starts after the 7-day trial. The pricing page we fetched showed euros (EUR 112.52 for SEO, billed annually, up to EUR 436.99 for Advanced), so USD buyers have to convert, and extra users start from EUR 43 per month. Prices checked on 2026-10-02.
Perplexity is an answer engine that replies with cited sources; it has a free tier, and its listed starting price is Education Pro at $10 per month, which requires student or faculty verification. ChatGPT also has a free tier, and Plus is $20 per month. Neither is described in our data as a keyword or AI-visibility tracker, so they suit ad hoc research rather than ongoing rank monitoring. Semrush One itself offers a free account with 10 reports per day.
"Better suited" below is based on documented features and pricing from our verified profiles, not on a head-to-head test. Prices are USD as published by each vendor.
Taken from the documented limitations in our Semrush One profile.
| Tool | Starting price | Free tier | Platforms | Main limitation |
|---|---|---|---|---|
| Semrush One (this page) | Not published | Yes | — | Plans cap tracked keywords and prompts, and the pricing page showed euros so USD prices are not confirmed. |
| Perplexity | $10/mo (Education Pro (consumer, verified students/faculty)) | Yes | Web, API | The consumer pricing page is blocked to automated checks, so the Pro price could not be confirmed here, and free-tier Pro Search and Research access are described only as 'very limited' / 'limited'. |
| ChatGPT | $20/mo (Plus (consumer)) | Yes | Web, Desktop, Mobile, API | Almost every tool (uploads, images, voice, deep research, Codex) has plan-dependent usage caps that OpenAI states can change over time, and the API is billed separately from every ChatGPT subscription. |
