Why Trust This Guide

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.

Getting Started with B12

Before touching any feature, finish this one-time setup.

It takes about three minutes.

Step 1: Create Your Account

Go to 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.

✓ Checkpoint: Check your inbox for the confirmation email.

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:

✓ Checkpoint: 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.

How to Use B12 AI Website Builder

AI Website Builder turns one plain description of your business into a working multi-page website.

Here’s how to use it step by step.

Step 1: Describe Your Business

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.

Here’s what this looks like:

✓ Checkpoint: You should see a draft site with a home page, services page, and contact form.

Step 3: Edit and Publish

Swap any text or image in the editor, then hit Publish.

Fix the homepage headline first. It carries more weight than anything below it.

How to Use B12 Blogging Tool

Blogging lets you write and ship blog posts inside the same dashboard as your site.

Here’s how to use it step by step.

Step 1: Open the Blog Tab

Click Blog in the left sidebar, then New Post.

Pick a topic your customers actually search for.

Step 2: Draft Your Post

Enter a title and let the AI build an outline you can edit.

Here’s what this looks like:

✓ Checkpoint: Your draft should appear in the post list marked Draft.

Step 3: Schedule or Publish

Set a publish date, or push it live straight away.

Scheduling two posts ahead keeps the blog alive during busy weeks.

How to Use B12 Third-Party Integrations

Third-Party Integrations connects your site to the outside tools you already pay for.

Here’s how to use it step by step.

Step 1: Open Integrations

Go to Settings, then Integrations.

The list is grouped by payments, scheduling, and analytics.

How to Use B12 On-Page SEO

On-Page SEO walks you through the title tags, meta descriptions, and headings on every page.

Here’s how to use it step by step.

Step 1: Open Page Settings

Select a page, then click the SEO tab.

Add a title tag and a meta description for that exact page.

Here’s what this looks like:

✓ Checkpoint: The preview snippet should show your title without a cut-off ellipsis.

Step 3: Run the Page Check

Missing alt text and duplicate H1 tags are the two most common flags.

How to Use B12 AI Agent

AI Agent answers visitor questions on your site and collects contact details while you sleep.

Here’s how to use it step by step.

Step 1: Enable the Agent

Go to AI Agent and toggle it on.

Choose which pages it appears on.

Step 2: Train It on Your Business

Paste your service list and your most common questions.

Here’s what this looks like:

✓ Checkpoint: A chat bubble should appear on your published site.

Step 3: Set the Handoff Rule

Send anything it cannot answer to your email.

Pricing questions are worth handling yourself. Let the agent pass those straight through.

How to Use B12 Email Marketer & Automation

Email Marketing & Automation sends campaigns and automatic follow-ups to the contacts already stored in your account.

Here’s how to use it step by step.

Step 1: Pick Your Audience

Open Email, then select a contact tag or your full list.

Step 2: Build the Campaign

Choose a template and edit the subject line and body.

Here’s what this looks like:

✓ Checkpoint: The campaign should show a recipient count before you send.

Step 3: Set the Trigger

Send now, or fire it when someone submits your contact form.

A same-day reply beats a polished one sent three days later.

How to Use B12 Customizable AI Website Prompts

Customizable AI Website Prompts rewrites any block on your page based on an instruction you type yourself.

Here’s how to use it step by step.

Step 1: Select a Section

Click any block, then choose Edit with AI.

Step 2: Write Your Prompt

Say what you want changed in one direct sentence.

Here’s what this looks like:

✓ Checkpoint: The section should update in place while the rest of the page stays untouched.

Step 3: Accept or Regenerate

Keep the new version, or run it again with a tighter prompt.

Two rounds is usually enough. Past that, edit the text by hand.

How to Use B12 Contact Manager

Contact Management keeps every lead, note, invoice, and booking on one contact record.

Here’s how to use it step by step.

Step 1: Open Contacts

Click Contacts to see everyone who filled in a form.

Step 2: Tag and Annotate

Add a tag and a short note after every conversation.

Here’s what this looks like:

✓ Checkpoint: Each contact should show its source page and the date it arrived.

Step 3: Take Action from the Record

Send an invoice or book a meeting without leaving the page.

Every action logs to the timeline, so nothing gets chased twice.

How to Use B12 Website Generator GPT

Website Generator GPT lets you build a starter site from inside ChatGPT, then bring it into your account.

Here’s how to use it step by step.

Step 1: Open the GPT

Find the B12 Website Generator in the ChatGPT store.

Step 2: Describe Your Site

Give it your business type, your city, and your main service.

Here’s what this looks like:

✓ Checkpoint: ChatGPT should hand back a live preview link to a draft site.

Open the link it returns and finish the site in B12.

Treat the GPT output as a rough draft. The real editing happens in the dashboard.

B12 Pro Tips and Shortcuts

After eight months inside the editor, these are the tips worth passing on.

Keyboard Shortcuts

Hidden Features Most People Miss

• Duplicate any page: Right-click a page in the sidebar to clone its layout for a new service.
• Invoicing from a contact: Open any contact record and bill them without opening a separate tool.
• Draft versions: Publish changes only when you’re ready. The live site stays untouched while you edit.

Here are the benefits that showed up fastest for me:

The time saved on setup was the one I felt immediately.

B12 Common Mistakes to Avoid

Mistake #1: Publishing the First Draft Untouched

Mistake #2: Ignoring Page-Level SEO

Mistake #3: Treating the CRM as an Address Book

B12 Troubleshooting

Problem: Your Custom Domain Won’t Connect

Cause: DNS records point somewhere else, or they haven’t propagated yet.

Fix: Copy the exact records from Settings into your registrar. Then wait up to 48 hours before retrying.

Problem: The Generated Copy Sounds Generic

Cause: Your original business description was too short or too vague.

Fix: Use the AI prompt tool on each section. Name your customer and your city in the instruction.

Problem: Contact Form Submissions Never Arrive

Cause: Notification emails are landing in spam, or the form is missing a recipient.

Fix: Set a recipient address under form settings. Then submit a test and whitelist the sender.

📌 Note: If none of these fix your issue, contact B12 support from the dashboard.
