Most studio work is paid once, at launch, and most client blogs stop there too. With Rankbox Studio, each client site gets its own research, its own brand voice and up to 30 scored, source-backed articles a month, delivered to the CMS you built under the client's name.
The trial covers one site. Client sites open in Studio with the first paid invoice.

In short
Rankbox is an AI search content engine that web design studios run as the monthly content retainer on sites they have built. One Studio account holds a site per client, each with its own research into the questions buyers ask ChatGPT, Perplexity, Gemini and Google AI Overviews, its own brand voice, and up to 30 scored, source-backed articles a month, delivered to the client's CMS under the client's name for $49.50 a site a month. It has no client logins, branded reports or citation tracking, so the client relationship, the review and the monthly report stay with the studio.
What it doesn't do
Client logins or branded reports
Team seats: one login per account
Citation, ranking or AI-mention tracking
Technical audits, speed or rendering fixes
Local listings, reviews or outreach link building
Keep the tools and partners you use for these. Rankbox covers research, articles and delivery.
The launch problem
Why the work stops at launch
A studio is paid to build. Once the site ships, the invoices stop, and the blog you designed usually stops with them.
Why retainers matter to a studio
58.3%
of WordPress agencies with no recurring revenue said they were rarely or never profitable in 2025.
Among those whose recurring revenue reached a quarter of the total, that share stayed under 10%.
The survey itself notes the link may run both ways: stronger agencies tend to move to retainers. Recurring revenue there means care plans, hosting and retainers, not content alone.
A content retainer bills every month on sites you have already built. Studio adds each one at $49.50 a month, on one invoice you pay and one price you set.
02
The blog template launches with three placeholder posts and never gets a fourth.
Articles arrive as items in the collection you designed, with title, slug, description, tags and body filled in, laid out by your template.
03
Clients ask whether they'll show up in ChatGPT, and you build sites, not SEO programs.
Rankbox researches the questions buyers ask AI engines and scores each article for being quoted. It doesn't report whether a client is cited, so the pitch can say so up front.
04
Hiring a writer who can sound like five different clients doesn't add up.
Each client site keeps its own brand voice, set once from that site: tone, audience and product details, applied to every draft.

A sample map for Brindlework, a fictional furniture workshop a studio might have built on Webflow. Each client's map is built from their own site, and nothing is written until you have reviewed the plan.
The questions each client's buyers ask AI engines and search, found from that client's own site.
1.2
Drafts in each client's voice
Long, source-backed articles written to the tone, audience and product details set for that site.
1.3
A score before it ships
Every article is scored for search and for being quoted in AI answers.
1.4
Delivery to the CMS
Finished articles handed to each site on the schedule you set, through that site's API key.
Your studio keeps this
2.1
The client
The proposal, the retainer price, every call and every invoice. Rankbox never contacts them.
2.2
The review
Reading and editing before anything goes live under the client's name, with a qualified reviewer for legal, medical or financial topics.
2.3
The monthly report
Built your way. Rankbox lists each site's articles and live links, with no branded reports or client logins.
2.4
The build
Templates, speed, technical SEO and listings. Rankbox doesn't audit or fix sites.
In the project
Where it fits in a project
Four moments in work you already run, from the proposal to every month after launch.
Proposal
Scope the retainer
Add a monthly content line to the proposal at a price you set. Rankbox never sees or bills the client.
Build
Design the collection
Build the blog collection and its template with the fields Rankbox fills: title, slug, description, tags and body.
Launch week
Add the site to Studio
Enter the site's address, check the brand Rankbox reads from it, pick the searches to win and review the first month of articles. Then connect the site with its own API key.
Every month
Review, publish, report
Articles arrive on the pace you set, held as drafts if you want a read first. You edit, publish and send the client your own report with the live links.
Features
The four features a retainer runs on
Rankbox does more than these. These are the four a studio leans on when the work goes out under a client's name.
The usual way a studio staffs content for its clients, line by line. No prices beside them: they vary too much to quote fairly.
A freelance writer per clientBriefed on each client's trade and voice, one at a time
Question and keyword researchA separate tool, or an afternoon in one, for every client
An editorial calendarA spreadsheet per client that drifts a month after launch
Pasting posts into the CMSCopying drafts into collection fields by hand
A pre-publish checklistHeadings, metadata and sources, checked by eye before each post
Rankbox covers the content side only. Technical SEO, site speed, local listings, outreach link building and the client report stay with your studio or the tools you already use.
Pricing
What a client site costs you
One price per site, on one invoice. What you charge the client is yours to set.
Your plan
Covers your first site: your studio's own, or a client's.
$49.50/mo
Each site in Studio
Its own research, voice, plan and 30 articles a month.
Not in the work. Articles carry no Rankbox badge, link or credit, in the text or in the structured data, and Rankbox never emails, calls or bills your clients. The name shows up in one place: the API key and the rankbox.xyz address in the site's code or integration settings, or an app named Rankbox once the Shopify and Webflow apps are approved.
Can clients log in to see their articles or a report?
No. There are no client logins and no branded reports, and an account has one login, with no team seats yet. You send the report. Rankbox lists every article for each site, with its live address once the site reports it, so building your own monthly summary takes the links straight from there.
Does it show whether a client appears in ChatGPT or Google's AI answers?
No. Rankbox doesn't track citations, rankings or AI mentions. It researches the questions buyers ask and scores every article for being quoted. To report on results, use the client's Google Search Console and GA4, plus a fixed set of prompts you check by hand each month.
How do articles get into a Webflow, Framer, WordPress or Shopify site?
Today articles reach every site through the Rankbox REST API, set up once per site with that site's own key. The Shopify and Webflow apps are built and waiting on store approval. Since your studio built the site, you're usually the developer that setup asks for: map the fields to the collection once, and finished articles keep arriving on that site's schedule.
Can I read articles before they go live on a client's site?
Yes. Rankbox has no separate approve step, because a finished article is ready to publish, so hold them at the destination instead: drafts in Webflow, hidden posts in Shopify, or a draft status in your own code. Edit anything in the editor first. Google's guidance on AI-assisted content asks publishers to fact-check and review it before it goes out, and a legal, medical or financial client needs a qualified person to sign off.
What does it cost the studio, and what do I charge?
Your plan is $49.50 a month and covers one site. Each client site in Studio is $49.50 a month on the same invoice, with its own 30 articles a month. What you charge the client is your decision; Rankbox never bills them. The 7-day trial covers one site, and Studio opens with your first paid invoice.
What happens when a client ends the retainer?
Remove their site from Studio. It keeps running to the end of the period you've paid for, then it's archived with its articles, keywords and settings kept, and you stop paying for it from the next invoice. The current period isn't refunded. Everything already published stays on the client's site.
Can my client sites link to each other?
Not through Rankbox. Each site's plan includes a backlink exchange allowance, still rolling out, and the exchange never trades links between sites one owner runs, because links between them would form a private link network. Link between client sites only where it helps a reader.
Does it handle technical SEO, speed or local listings?
No. Rankbox doesn't audit sites, fix rendering or speed, manage Google Business Profiles or reviews, or do outreach link building. That's build and care-plan work your studio already does, or keeps the tools for.
