SEO brief + AI draft, agency-shaped
Xt4b vs GrowthBar.
GrowthBar and Xt4b look the closest on shape — both per-site, both brief + draft. The difference is in how the brief is built (keyword-driven vs gap-driven) and what runs after the draft ships.
Where each one wins.
Two honest lists — the competitor first, because pretending otherwise is how comparison pages lose trust.
Where GrowthBar is the right pick
- Mature keyword research tooling with a strong keyword database and competitive analysis, useful as a standalone research step.
- Tight integration with WordPress and a couple of popular page builders, for teams already in that ecosystem.
- A more polished AI-writer experience, for teams whose bottleneck is the writing step specifically.
Where Xt4b is
- The brief is gap-driven, not just keyword-driven — every entry knows which page on your site is already trying to rank for that query, and skips it instead of competing with it.
- Per-language calendars — each language runs its own plan and cadence on the same site, no extra setup.
- Publishing to a custom subdomain or apex with sitemap and canonical handled, so the plan lands as live URLs.
Compare like for like.
The same dimensions, asked of both tools. Empty cells mean the tool does not have that capability — not that we forgot a tick.
| Model | GrowthBar | Xt4b |
|---|---|---|
| Plans against your existing sitemap | Keyword-driven | Built in |
| Drafts the post | Built in | End to end |
| Per-language calendar | Separate per language | Built in |
| Publishes on a schedule | Built in | Built in |
| Pricing | Per site, fewer languages included | €10 / site / language |
What the comparison actually is.
GrowthBar and Xt4b overlap the most in shape: both sell per-site subscriptions, both generate a brief, both write a draft, both post to a calendar. The difference is in how the brief is built. GrowthBar's brief is keyword-driven, Xt4b's brief is gap-driven — every entry knows which page on your site is already trying to rank for that query, and skips it instead of competing with it.
- 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
GrowthBar is the right tool when the keyword list is the deliverable. Xt4b is the right tool when the page itself is the deliverable — dated posts on a real domain.
Fit checklist
Pick GrowthBar over Xt4b if any of these describes your team.
- A team whose bottleneck is keyword research and who wants a standalone research step.
- A team on WordPress or a page builder where GrowthBar's integrations fit cleanly into an existing setup.
- A team that does not need a per-language plan and prefers a flat per-site subscription.
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 GrowthBar customers keep one seat open for keyword research, while the publishing cadence moves to Xt4b. After two months the keyword lists overlap enough that GrowthBar is the easier retirement.
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.
Live SERP-driven editor + audit
Surfer SEO
Surfer and Xt4b share a philosophy: the post should look like the page already ranking, and both run on the same SERP data. Xt4b moves the grading step into the brief so it happens once, before writing, and also publishes the post.
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.
Questions about the switch.
The ones that come up after the verdict has landed, before the budget conversation starts.
Does Xt4b include keyword research?
The gap report lists the queries your site is missing, which is what most teams use keyword research for. Xt4b does not include a standalone keyword database like GrowthBar's — for that, GrowthBar or a dedicated keyword tool is still the better fit.
Which is better for an agency running 30 client sites?
Xt4b, because the per-site pricing scales linearly without per-seat fees and the per-language plan lets a single client with three markets run as three lines instead of three seats of a per-user product.
Does Xt4b have competitive SERP analysis?
No. Xt4b plans against your existing site, not against competitors' SERPs. For a standalone competitive SERP report, GrowthBar or Surfer is still the better fit.
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.
