Content Optimization
Surfer: what it does, what it costs
Content scored against what already ranks, with AI-answer tracking attached.
Surfer at a glance
Every row is a verified field or an honest absence. A row is dropped rather than filled with an em dash, so the length of this table says how complete the record is.

What Surfer is
Surfer analyses the pages currently ranking for a query, extracts the terms and structure they share, and scores a draft against that model. Content Score is the most widely adopted metric of its kind, which matters practically: a freelance writer briefed on "hit 70 in Surfer" understands the instruction without training.
The design decision that makes it work is where it runs. Optimisation happens inside Google Docs and WordPress rather than in a separate app, so writers are not asked to draft in one place and grade in another, the step most content workflows quietly skip.
Two things to read carefully before buying. The pricing page quotes annual billing by default, so the monthly rates are not the numbers on the page. And AI-visibility tracking is tiered aggressively: 25 prompts on ChatGPT only, refreshed weekly, on the $99 plan, against 50 prompts daily across five surfaces on the $182 one.
Surfer in context
Surfer built its reputation on the Content Score, and the Content Score is both the product’s strongest asset and its most misunderstood feature. A high score means a draft covers the same terms as the pages currently ranking. It does not mean the draft is good, or that it will rank. The gap list underneath the score — the specific terms the draft is missing — is where the actual value lives, and most users never scroll past the number.
The Google Docs and WordPress integrations are what make Surfer practical for content teams. Writers draft where they already work, and the optimisation feedback appears in real time without a copy-paste step. That workflow integration is the reason teams pick Surfer over alternatives with comparable scoring: the best brief in the world is useless if the writer has to leave their editor to read it.
AI search visibility tracking is now part of the product, but the allowances vary dramatically by plan. Standard covers ChatGPT only at 25 prompts refreshed weekly. Getting daily refresh across ChatGPT, Perplexity, Google AI Overviews and Gemini means paying for Pro at $182 a month, or buying the standalone tracker at $158. For a team already paying for Surfer, bundling this avoids a second subscription. For a team that only wants AI tracking, a dedicated tool covers more engines for less.
The pricing structure deserves attention. The headline rates are annual billing — Discovery at $49 a month and Standard at $99. Paying monthly costs meaningfully more, and the savings advertised on the pricing page ($120 on Discovery, $240 on Standard) are the difference. Plan against the annual commitment or plan against the real monthly cost; the number in between does not exist.
What you can use it for
- Score a draft against the pages currently ranking, and see the coverage gaps before publishing
- Brief a freelance writer against a target Content Score rather than a vague outline
- Plan a content cluster from a topical map instead of a keyword list
- Track whether AI assistants cite your pages, on the Pro tier or as a standalone add-on
The features that matter for SEO
Each one says what it does and the SEO job it serves. A vendor feature list without that second half tells you nothing you could not read on their own site.
Content Score
Grades a draft from 0 to 100 against the terms, structure and depth of the pages currently ranking for the target query.
A shared number a writer, an editor and a client can all work to, which is most of why it became the category default.
A score is a model of the current SERP, not a ranking prediction. Chasing 100 produces prose that reads as machine-written.
Content Editor in Google Docs and WordPress
Runs the brief, outline and term coverage inside the tools writers already use.
Removes the copy-paste step between drafting and grading, the step that gets skipped, which is when optimisation stops happening.
Topical map
Generates a cluster of related topics around a subject, with suggested structure.
Turns one commercial term into a planned cluster, which is how a SaaS category page earns supporting coverage.
AI visibility tracking
Tracks prompts across ChatGPT, Perplexity, Google, AI Overviews and Gemini, with mention gap, sentiment and share of voice.
Measures whether the content work is producing citations rather than only rankings.
Standard covers ChatGPT alone at 25 prompts refreshed weekly. Daily refresh across five surfaces starts on Pro at $182 a month.
Cannibalisation and rank-drop reporting
Flags pages competing for the same query and alerts on ranking decay.
On a site with years of content, cannibalisation is a more common cause of stalled growth than a lack of coverage.
One-click internal linking
Suggests and inserts contextual internal links across the site.
The cheapest ranking gain on an established site, and the job nobody does by hand past a few hundred pages.
Pro and above.
Surfy and Humanizer
Drafts and rewrites content inside the editor.
Useful for a first pass on a structured section. Everything it produces still needs an editor who knows the subject.

Alternatives to Surfer
Each one answers when it is the better choice, which is the only thing a list of competitors is useful for.
- Clearscope Choose it when the team is large, because every plan carries unlimited users and the price is set by pages rather than headcount.
- Frase Choose it when you want research, drafting, publishing and decay monitoring in one product at the lowest entry price.
- Semrush Choose it when content optimisation is one job among many and you would rather have it inside a suite you already pay for.

Questions
How much does Surfer cost per month?
The pricing page quotes annual billing, where Discovery is $49 a month and Standard is $99 a month as of 18 August 2026. Paying monthly costs more, the page advertises annual savings of $120 on Discovery and $240 on Standard, which is the difference.
Does Surfer track AI search visibility?
Yes, but the allowance matters. Standard covers ChatGPT only, at 25 prompts refreshed weekly. Daily refresh across ChatGPT, Perplexity, Google, AI Overviews and Gemini starts on Pro at $182 a month, and the tracking can also be bought on its own for $158 a month.
Is a high Content Score enough to rank?
No. The score measures how closely a draft resembles the pages currently ranking, which is a useful check on coverage and a poor proxy for quality. Use the gap list; ignore the last ten points.
