For SEO content the draft is the easy part. What ranks is the data layer underneath it: SERP analysis, term coverage, and a score that tells you when a page is actually competitive. We reweighted the rubric around the optimization engine and ranked the five tools by cost per ranked article, not per word.
For SEO content we weight the optimization engine highest, because a fluent draft with no SERP data behind it is just words. The tools that win pair generation with real term-coverage scoring; the ones that do not make you pay twice. See the full rubric →

Surfer SEO
Best optimization engine
The category standard for a reason: the Content Editor scores your draft against live SERP term coverage in real time, so you write to a target instead of guessing. Essential is $99/mo for 30 Content Editor articles, which pencils out around $3.30 per optimized article. Watch the add-ons, the AI Tracker is another $95/mo.
The value play. It pulls the SERP, builds the brief and scores your draft for a lower entry price than Surfer, so a solo SEO or small team gets most of the workflow for less. Starter is $49/mo but caps you at 10 articles; the cost per article climbs fast at volume, which is where Surfer overtakes it.
The best pure writer here, with the cleanest long-form prose and brand voice. But native SEO scoring is not its job; it leans on a Surfer integration to optimize, which means you are buying two tools. Pick it when draft quality matters more than the data layer, and budget for the SEO tool alongside.
Bulk generation with some SEO features at a low headline price, which is the appeal for content farms. The pricing tiers shift and the strongest optimization sits on pricier plans, so the cheap number rarely survives contact with the workflow you actually need. Good for volume drafts, weaker for ranking precision.
Strong at ads, emails and workflow automation, with no real SEO data layer for long-form. If your job is ranking blog pages, this is the wrong tool; if it is producing volumes of short marketing copy, it is excellent. Free to start, $49/mo Starter, $249/mo for the workflow tier.

Common questions
What is the one feature that decides an SEO writing tool?
The optimization engine: live SERP analysis and a term-coverage score you write toward. That is the difference between content that ranks and content that merely reads well, which is why we weighted it at 35%. Surfer and Frase have it natively; pure generators do not.
Surfer or Frase for a small content team?
Frase if budget is tight and you publish a handful of articles a month, since it bundles research, briefs and scoring at a lower entry price. Surfer once you scale, because its per-article cost on the 30-article Essential plan beats Frase as volume rises, and its Content Editor is the more precise optimizer.
Can I just use Jasper or ChatGPT for SEO content?
You can draft with them, but you will not know if the page is competitive without a SERP data layer, so most teams bolt on Surfer or Frase anyway and pay twice. If ranking is the goal, buy the optimization tool first and add a generator second, not the reverse.
How should I compare cost, per seat or per article?
Per article. SEO content is a volume game, so the number that matters is cost per optimized article at your real monthly output. Surfer Essential at $99 for 30 articles is roughly $3.30 each; Frase Starter at $49 for 10 is closer to $4.90 and rises faster once you exceed the cap.
