为什么信任本指南

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 客户关系管理 tools sitting unused.

This guide shows you how to use all nine, step by step.

B12教程

This How to Use B12 tutorial walks through every B12 feature in order, from your first login to the 自动化 most people never switch on.

Describe your 商业 in one sentence and get a full website draft in about 60 seconds. B12 bundles blogging, on-page SEO, an AI agent, email automation, invoicing, and a built-in 客户关系管理 into one dashboard. Build and preview your site before you pay anything.

B12入门

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

大约需要三分钟。

第一步：创建您的帐户

前往 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.

✓ 检查点： 检查你的 收件箱 用于确认邮件。

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:

✓ 检查点： 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.

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.

这就是它的样子：

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

步骤三：编辑并发布

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

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

B12 避免的常见错误

Mistake #1: Publishing the First Draft Untouched

Mistake #2: Ignoring Page-Level SEO

Mistake #3: Treating the CRM as an Address Book

B12故障排除

Problem: Your Custom Domain Won’t Connect

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

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

Problem: The Generated Copy Sounds Generic

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

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

Problem: Contact Form Submissions Never Arrive

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

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

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