Live SERP-driven editor + audit
Xt4b vs Surfer SEO.
Surfer is the live-grader in the category. Xt4b is the publishing layer. The question is whether you need grading while you write or whether you need posts that already ship — and the answer usually depends on how many writers you have.
Where each one wins.
Two honest lists — the competitor first, because pretending otherwise is how comparison pages lose trust.
Where Surfer SEO is the right pick
- Live, in-editor grading with term-level suggestions while you write. Surfer's Chrome extension is still the fastest iteration loop in the category, and that workflow is hard to replace if a team has built around it.
- Mature SERP analysis with structured data, image count and word-count targets pulled directly from ranking pages. The audit feature, run against a real site with thousands of URLs, is genuinely useful.
- Topical Map, the newer research product, is a real competitor for the 'what should we write next' question — it sits alongside the editor and Audit and the three pieces talk to each other.
Where Xt4b is
- The plan is written before the draft. By the time a writer opens Google Docs the query, intent, outline, terms and links are already in the brief, so the Surfer extension has less variance to catch.
- Publishing on a date with a per-language calendar, on a blog on your own domain with its own sitemap. Surfer writes briefs and grades drafts; Xt4b ships the posts.
- Per-site, per-language pricing instead of per seat. A team of five editors on one site is five Surfer seats or one Xt4b plan.

| Model | Surfer SEO | Xt4b |

| Plans before writing | Topical Map | Built in |
| Drafts the post | – | End to end |

| Pricing | Per seat, per tier | €10 / site / language |
What the comparison actually is.
Surfer is the live-grader in the category. The Chrome extension scores the page the writer is on, suggests terms, and pushes the score up in real time. The SERP analysis is solid: word count, image count, heading structure pulled from the ranking pages. Audit is mature. Topical Map is the newer gap-research product and pairs well with the editor.
- Plans before writing
- Yes, as part of the same workflow.
- Drafts the post
- Yes — that is the core offer.
- Schedules publishing
- Usually no. Most of these tools hand the draft back to your CMS or a separate scheduler.
- Pricing
- Per seat in the competitor's case, per site and per language in Xt4b's.
The honest verdict.
One sentence per tool — who should pick the competitor, and who should pick Xt4b.
One sentence
Surfer is the right pick when grading a draft is the bottleneck. Xt4b is the right pick when having the draft in the first place, on a date, on a real domain, is the bottleneck.
Fit checklist
Pick Surfer SEO over Xt4b if any of these describes your team.
- A writer who wants the SERP score to update live as they edit, not in a post-mortem step.
- A team running a topic-cluster strategy and needing the Topical Map visualisation for stakeholder decks.
- An enterprise team auditing tens of thousands of legacy URLs and needing Site Audit at that scale.
If you decide to switch.
The shape of a normal handoff from this competitor to Xt4b — written so the first month is not a step backward.
How to move without losing work
Most teams keep one Surfer seat open for in-editor grading on flagship pieces, while the publishing cadence moves to Xt4b. In practice the two tools do not overlap much: Surfer is for crafting, Xt4b is for shipping. Teams that retire Surfer tend to do it within two months, once the brief is good enough.
Other comparisons.
Four more /vs pages, one for each competitor that comes up in the same conversations as this one.
Content grading editor + inventory
Clearscope
Clearscope is the strongest content grader in the category — open a draft in Google Docs or Word and it tells the writer which terms to add and which sentences to cut. Xt4b produces the draft in the first place, with the same grading applied at the brief stage, not after writing.
Topic authority + content inventory
MarketMuse
MarketMuse is the original content intelligence platform. Its inventory is the deepest in the category, the topic authority score is the one leadership teams ask for, and the first-party data layer is genuinely useful at scale. Xt4b does the same gap research and then goes further — drafting the post and shipping it on a date.
Brief generator + AI writer
Frase
Frase and Xt4b look the closest on the surface — both turn a SERP into a draft. They diverge on three things: Xt4b plans against your existing site, Frase plans against the SERP; Xt4b publishes on a date, Frase hands you a draft; Xt4b charges per site, Frase charges per user.
SEO brief + AI draft, agency-shaped
GrowthBar
GrowthBar is the closest competitor on shape — per-site subscription, brief plus draft, calendar. Xt4b differs in the planning layer: every entry checks your existing sitemap so the plan never duplicates a URL you already publish, and the per-language calendar is built in.
Questions about the switch.
The ones that come up after the verdict has landed, before the budget conversation starts.
Does Xt4b include a content editor?
No. Xt4b ships the plan (query, intent, outline, metadata, links) and publishes. The draft itself is written in whatever editor your writer prefers — Google Docs, a CMS, Surfer's editor, anything.
Which is better for an agency running 20 client sites?
Xt4b, because the per-site pricing scales linearly without per-seat fees, and the per-language plan lets one client with three markets run as three lines instead of three seats of a per-user product.
Does Xt4b do Topical Map?
The gap report covers the same query space — what to write next, with what intent, in what order. Xt4b does not produce a node-and-edge graph of the topic cluster the way Topical Map does; for that visualisation specifically, Surfer is still the better tool.
Is there anything to do after switching?
Yes, but it is small. Connect the new domain in Vercel, point the blog subdomain at it, and run the free scan so Xt4b knows what to plan against. The migration notes on each /vs page have the exact steps for that competitor, but the default is: import the plan, scan once, publish on a schedule.
