このガイドを信頼する理由
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.
B12チュートリアル
This How to Use B12 tutorial walks through every B12 feature in order, from your first login to the オートメーション most people never switch on.
ビタミンB12の始め方
Before touching any feature, finish this one-time setup.
約3分かかります。
ステップ1：アカウントを作成する
行く 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.
✓ チェックポイント: チェックしてください 受信トレイ 確認メールについて。
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:
✓ チェックポイント: 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.
✅ 完了: これで、以下のすべての機能をご利用いただけます。
B12 AIウェブサイトビルダーの使い方
AIウェブサイトビルダー turns one plain description of your business into a working multi-page website.
以下に、その使用方法をステップごとに説明します。
ステップ1：あなたのビジネスを説明する
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.
これがその様子です。
✓ チェックポイント: You should see a draft site with a home page, services page, and contact form.
ステップ3：編集して公開する
Swap any text or image in the editor, then hit Publish.
Fix the homepage headline first. It carries more weight than anything below it.
✅ 結果: You have a live, editable website built from one sentence.
💡 プロのヒント: Generate two drafts using slightly different descriptions. Keep whichever layout reads better.
How to Use B12 Blogging Tool
ブログ lets you write and ship blog posts inside the same dashboard as your site.
以下に、その使用方法をステップごとに説明します。
Step 1: Open the Blog Tab

Step 2: Draft Your Post
Enter a title and let the AI build an outline you can edit.

ステップ3：スケジュール設定または公開
Set a publish date, or push it live straight away.
Scheduling two posts ahead keeps the blog alive during busy weeks.
✅ 結果: A finished post sits on your site with clean formatting and internal links.
💡 プロのヒント: Write the title before the outline. The AI follows a sharp title far more closely.
B12サードパーティ統合機能の使い方
サードパーティ統合 connects your site to the outside tools you already pay for.
以下に、その使用方法をステップごとに説明します。
ステップ1：統合機能を開く
Go to Settings, then Integrations.

以下に、その使用方法をステップごとに説明します。
ステップ1：ページ設定を開く

Add a title tag and a meta description for that exact page.
これがその様子です。

Step 3: Run the Page Check
Click Check and clear anything flagged in red.
Missing alt text and duplicate H1 tags are the two most common flags.
✅ 結果: Every page carries its own title, description, and clean heading order.
💡 プロのヒント: Keep title tags under 60 characters. Anything longer gets trimmed in search results.
B12 AIエージェントの使い方

Step 1: Enable the Agent
Go to AI Agent and toggle it on.

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

A same-day reply beats a polished one sent three days later.
✅ 結果: New leads get a follow-up email without you touching anything.
💡 プロのヒント: Send yourself a test first. Broken merge tags are obvious in a real inbox.
B12カスタマイズ可能なAIウェブサイトプロンプトの使い方

以下に、その使用方法をステップごとに説明します。
ステップ1：セクションを選択する

ステップ2：プロンプトを作成する
Say what you want changed in one direct sentence.
これがその様子です。
✓ チェックポイント: The section should update in place while the rest of the page stays untouched.

Keep the new version, or run it again with a tighter prompt.
Two rounds is usually enough. Past that, edit the text by hand.
✅ 結果: Your copy sounds like your business instead of a template.
💡 プロのヒント: Name your audience in the prompt. ‘Rewrite for busy dentists’ beats ‘make it better’.

Send an invoice or book a ミーティング without leaving the page.
Every action logs to the timeline, so nothing gets chased twice.

💡 プロのヒント: Tag by source, not by status. Source tags tell you which pages actually earn money.
B12ウェブサイトジェネレーターGPTの使い方
Webサイト ジェネレータ GPT lets you build a starter site from inside ChatGPT, then bring it into your account.
以下に、その使用方法をステップごとに説明します。
ステップ1：GPTファイルを開く
Find the B12 Website Generator in the チャットGPT 店。
Step 2: Describe Your Site
Give it your business type, your city, and your main service.
これがその様子です。
✓ チェックポイント: ChatGPT should hand back a live preview link to a draft site.
Step 3: Import and Refine
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.
✅ 結果: You go from idea to draft site without opening a builder first.
💡 プロのヒント: Ask the GPT for three homepage headline options before you import. Editing later takes longer.

Here are the benefits that showed up fastest for me:
The time saved on setup was the one I felt immediately.
ビタミンB12に関するよくある間違いを避ける
Mistake #1: Publishing the First Draft Untouched
❌ 間違い: Generating a site and hitting Publish within five minutes.
✅ 右: Rewrite the homepage headline and service descriptions first. AI copy is a starting point, not finished text.
Mistake #2: Ignoring Page-Level SEO
❌ 間違い: Leaving every page with the same default title tag.
✅ 右: Give each page its own title and meta description before you announce the site.
Mistake #3: Treating the CRM as an Address Book
❌ 間違い: Collecting form submissions and never tagging or following up on them.
✅ 右: Tag every lead by source, then trigger an automatic follow-up email the same day.
B12のトラブルシューティング
Problem: Your Custom Domain Won’t Connect
原因： DNS records point somewhere else, or they haven’t propagated yet.
修理： 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.
修理： 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.
修理： Set a recipient address under form settings. Then submit a test and whitelist the sender.
📌 注記： If none of these fix your issue, contact B12 support from the dashboard.
