Semrush edges out Frase on user ratings (4.6 vs 4.3 out of 5), though both remain solid choices depending on your priorities. Neither tool has a free tier — Frase starts at Free trial / $15/mo and Semrush starts at $139–$499/mo, so factor trial periods into your evaluation. Frase tends to be favoured by content-creators, while Semrush is more popular with seo and agencies.
Put Frase next to Semrush and the differences surface fast — Frase is built around seo tools while Semrush leans toward marketing tools. Frase is best known for serp research, whereas Semrush stands out for keyword research. On aggregate user ratings Semrush holds a slight edge (4.3/5 vs 4.6/5), though that gap rarely decides the match on its own.
Where Frase pulls clearly ahead is generating SEO content briefs from SERP analysis in one click. A frequent plus in reviews: Cheapest full-stack SEO writing tool ($15/mo). Semrush, by contrast, is the stronger choice for running full competitor analysis across SEO, PPC, and content simultaneously. In its favour: Most comprehensive SEO data — especially for keyword research workflows where Semrush consistently outperforms manual approaches. The feature checklists overlap, but the day-to-day experience does not.
Frase combines what Surfer SEO and an AI writer do separately into one tool — for teams that want a unified workflow, it removes significant context switching. Semrush is the right choice for agencies managing multiple marketing channels — the breadth of PPC, social, content, and SEO tools justifies the premium. For most teams the deciding factor is existing workflow and budget, not a marginal feature gap.
Choose Frase if you are focused on content writers and SEO agencies producing long-form content who want keyword research, brief creation, and AI writing all in one workflow — without switching between multiple tools, or if a big part of your week goes to using AI to write content sections guided by top-ranking competitor analysis. It rewards teams ready to commit to a paid plan from the start.
Choose Semrush if your priority is digital marketing agencies and in-house teams who need a single platform covering SEO, paid search, content strategy, and competitor intelligence across all digital channels — not just organic search, especially for finding keyword gaps — terms competitors rank for that you're missing. Note there is no free plan, so plan for a paid tier from day one.
On reliability and output quality, both are dependable, but Frase shines at generating SEO content briefs from SERP analysis in one click and Semrush at running full competitor analysis across SEO, PPC, and content simultaneously.
Learning curve is worth weighing. Frase has a known trade-off — AI writing quality below dedicated tools like Jasper. On Semrush's side: $139–$499/mo puts it out of reach for individual users and very small teams on tight budgets. Factor in the integrations you already rely on — that usually settles which one sticks after the trial.
Neither leads with a free plan, so expect to evaluate on a paid tier or a trial. Paid plans start at $14.99/mo for Frase (Solo) and $119/mo for Semrush (Pro), making Frase the cheaper entry point at $14.99/mo versus $119/mo. The extra spend on Semrush only pays off if you need what its higher tier unlocks.
