Por que confiar neste guia?
I’ve run B12 for eight months and tested every feature covered here. This tutorial comes from real hands-on use, not vendor screenshots.
B12 is one of the fastest AI website builders available today.
But most users stop after generating their first draft.
That leaves the blogging, SEO, email, and CRM tools sitting unused.
This guide shows you how to use all nine, step by step.
Tutorial B12
This How to Use B12 tutorial walks through every B12 feature in order, from your first login to the automação most people never switch on.
Primeiros passos com a vitamina B12
Before touching any feature, finish this one-time setup.
Leva cerca de três minutos.
Passo 1: Crie sua conta
Vá para b12.io and click Get Started.
Enter your email address and a password.
You’ll be asked what your business does before you reach the dashboard.
✓ Ponto de verificação: Verifique o seu caixa de entrada para o e-mail de confirmação.
Step 2: Open Your Draft Site
B12 runs in the browser, so there is nothing to download.
Log in and your generated draft loads automatically.
Here’s what my own first draft looked like:
✓ Ponto de verificação: You should land on the dashboard with a draft site listed.
Step 3: Finish Initial Setup
Upload your logo and set your brand colours under Design.
Add your business address, phone number, and working hours.
Connect a custom domain now if you already own one.
✅ Concluído: Você está pronto para usar qualquer recurso abaixo.

Open the builder and type what your business does.
Keep it to one or two plain sentences. Skip the buzzwords.
Step 2: Generate Your Draft
Click Generate and wait about 60 seconds.
Eis como isso se parece:
✓ Ponto de verificação: You should see a draft site with a home page, services page, and contact form.
Etapa 3: Editar e Publicar
Swap any text or image in the editor, then hit Publish.
Fix the homepage headline first. It carries more weight than anything below it.
✅ Resultado: You have a live, editable website built from one sentence.
💡 Dica profissional: Generate two drafts using slightly different descriptions. Keep whichever layout reads better.

Set a publish date, or push it live straight away.
Scheduling two posts ahead keeps the blog alive during busy weeks.

Click Check and clear anything flagged in red.
Missing alt text and duplicate H1 tags are the two most common flags.
✅ Resultado: Every page carries its own title, description, and clean heading order.
💡 Dica profissional: Keep title tags under 60 characters. Anything longer gets trimmed in search results.

Erros comuns a evitar em relação à vitamina B12
Mistake #1: Publishing the First Draft Untouched
❌ Errado: Generating a site and hitting Publish within five minutes.

❌ Errado: Leaving every page with the same default title tag.
✅ Direita: Give each page its own title and meta description before you announce the site.
Mistake #3: Treating the CRM as an Address Book

✅ Direita: Tag every lead by source, then trigger an automatic follow-up email the same day.
Solução de problemas da vitamina B12
Problem: Your Custom Domain Won’t Connect
Causa: DNS records point somewhere else, or they haven’t propagated yet.
Consertar: Copy the exact records from Settings into your registrar. Then wait up to 48 hours before retrying.
Problem: The Generated Copy Sounds Generic
Causa: Your original business description was too short or too vague.
Consertar: Use the AI prompt tool on each section. Name your customer and your city in the instruction.
Problem: Contact Form Submissions Never Arrive
Causa: Notification emails are landing in spam, or the form is missing a recipient.
Consertar: Set a recipient address under form settings. Then submit a test and whitelist the sender.
📌 Observação: If none of these fix your issue, contact B12 support from the dashboard.
