このガイドを信頼する理由

I have used Writesonic for eight months across client blog posts, product descriptions, and paid ad copy.

Every screenshot and every step below comes from my own account, not a vendor demo.

How to use Writesonic

Writesonic is an ai writing tool built on GPT-4 class models, and it now bundles SEO tooling alongside content generation.

It uses artificial intelligence to turn a rough idea into high quality content in minutes, from blog posts to compelling product descriptions.

Most people open it, generate one blog post, and never touch the other 90% of the platform.

This step by step guide fixes that.

Writesonicチュートリアル

This How to Use Writesonic tutorial walks through every feature in order, from your first login to the advanced features that make the tool an invaluable asset.

ライトソニック

Write, edit, and rank in one place. Writesonic pairs an ai article writer with キーワードリサーチ, site audits, and AI visibility tracking. Start on the free trial and keep 10,000 words.

Writesonicを使い始める

Do this one-time setup before touching any writing tools.

約3分かかります。

ステップ1:アカウントを作成する

Go to the Writesonic website and click Sign Up.

Enter your email and pick a password, or use Google.

The free plan starts immediately, so this is a risk free way to test the platform.

✓ チェックポイント: A confirmation email lands in your 受信トレイ within a minute.

ステップ2:ダッシュボードを開く

Writesonic runs in the browser, so there is nothing to install.

Log in and you land on a user friendly interface with every tool grouped down the left side.

Here is what my workspace looks like after a few months of use:

Writesonicでの個人的な体験

✓ チェックポイント: You can see the main dashboard with the tool list on the left.

Step 3: Set Your Brand Voice

Open Settings and paste two or three samples of your own writing.

Writesonic reads the tone, sentence length, and vocabulary, then applies that brand voice to everything it drafts.

Skip this and you get generic copy that sounds like every other AI blog.

✅ 完了: Your account is ready and your brand’s personality is loaded.

Writesonic Article Writerの使い方

記事ライター lets you turn one keyword into a full article draft in under ten minutes.

以下に、その使用方法をステップごとに説明します。

Generating content this way beats staring at a blank page for an hour.

ステップ1:主要キーワードを入力してください

Open Article Writer 6.0 from the dashboard.

Type your primary keyword, then add two or three secondary keywords.

Writesonic pulls live data from search engines to see what already ranks.

Step 2: Approve the Outline

The tool returns an engaging title plus an AI generated outline.

Drag headings around or delete the ones your target audience will not care about.

これは以下のようなものです。

Writesonic記事ライター

✓ チェックポイント: A clean H2 and H3 skeleton with word count estimates per section.

ステップ3:生成と編集

Hit generate and wait roughly four minutes for the full article.

Run the built-in seo optimization pass to lift your content’s visibility.

Read it line by line before publishing.

✅ 結果: A 1,500 to 3,000 word draft with internal links and images already placed.

💡 プロのヒント: Upload your own files as reference material first. The AI writer mirrors that source instead of guessing.

Writesonic Humanizerの使い方

ヒューマナイザー lets you rewrite AI generated text so it reads like a person wrote it.

以下に、その使用方法をステップごとに説明します。

The point is making sure your content aligns with how you actually talk.

ステップ1:下書きを貼り付ける

Open Humanizer and paste any written content you want softened.

It works on Writesonic output or text from other AI writing tools.

Step 2: Pick a Content Style

Choose casual, professional, or academic.

Add additional instructions if you want a specific writing style kept intact.

これは以下のようなものです。

ライトソニック・ヒューマナイザー

✓ チェックポイント: A split screen showing original text on the left, rewritten text on the right.

Step 3: Compare and Keep

Read both versions side by side.

Keep the sentences that sound like you and reject the rest.

✅ 結果: Copy that keeps your meaning but loses the stiff, repetitive AI writing rhythm.

💡 プロのヒント: Run short blocks, not whole articles. Paragraph-level passes protect brand consistency far better.

How to Use Writesonic Content Gap Analyzer

コンテンツギャップ分析 lets you see exactly which subtopics top ranking articles cover and yours skips.

以下に、その使用方法をステップごとに説明します。

Step 1: Add Your URL

Paste your published page and up to three competitor pages.

Writesonic crawls all of them in about thirty seconds.

Step 2: Read the Gap Report

You get missing subtopics, entities, and questions ranked by how often rivals mention them.

これは以下のようなものです。

Writesonicのコンテンツギャップ分析

✓ チェックポイント: A colour-coded list where red rows mark topics you have not covered at all.

Step 3: Feed Gaps Back In

Send the gap list straight into the article writer as additional instructions.

✅ 結果: A concrete revision checklist instead of a vague feeling that the post is thin.

💡 プロのヒント: Ignore gaps mentioned by only one rival. Chasing every gap wrecks keyword density and reads padded.

Writesonic Chatsonicの使い方

チャットソニック lets you research topics with live search data instead of stale training data.

以下に、その使用方法をステップごとに説明します。

It is the quickest way to generate ideas when the topic is new to you.

Step 1: Start a Chat

Open Chatsonic from the left sidebar.

Ask a question the way you would ask a colleague.

Step 2: Attach Sources

Upload a PDF, a spreadsheet, or a URL.

Chatsonic reads it and answers using those specific details.

これは以下のようなものです。

ライトソニック チャットソニック

✓ チェックポイント: Answers arrive with cited links you can open and verify.

Step 3: Send Output Downstream

Push the answer into a document or a blog post draft with one click.

✅ 結果: A research brief built from current sources, not guesswork.

💡 プロのヒント: Ask Chatsonic to generate fresh ideas as angles, not headlines. Angles survive editing.

Writesonic AI Visibility Tracker の使い方

AI可視化トラッカー lets you track how often AI platforms mention your brand in their answers.

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:ブランドを追加する

Enter your domain and up to five competitors.

Add the prompts your customers actually type.

Step 2: Review the Scoreboard

The dashboard shows mention share per platform, updated weekly.

これは以下のようなものです。

Writesonic AI可視化トラッカー

✓ チェックポイント: A percentage score per platform sitting next to each competitor.

Step 3: Act on Weak Prompts

Find prompts where rivals win, then build content aimed at those questions.

✅ 結果: Hard numbers on brand visibility instead of guessing whether AIツール know you exist.

💡 プロのヒント: Track buying-intent prompts first. Informational prompts look flattering but rarely convert.

Writesonic Audit & Issue Fixer の使い方

監査 & 問題解決者 lets you find technical issues across your site and push fixes without a developer.

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:サイトを接続する

Verify ownership through Search Console or a small script.

The crawl finishes in a few minutes for most small businesses.

Step 2: Sort by Severity

Broken links, thin pages, and missing meta tags appear at the top.

これは以下のようなものです。

Writesonic監査および問題解決ツール

✓ チェックポイント: A severity list with an estimated traffic インパクト beside each issue.

ステップ3:修正を適用する

Approve the suggested fix and Writesonic writes the replacement tag for you.

✅ 結果: A cleaner site that search engines can crawl without tripping over errors.

💡 プロのヒント: Fix indexing errors before rewriting copy. No amount of engaging content outranks a blocked page.

Writesonic SEO AIエージェントの使い方

SEO AIエージェント lets you hand off repeat writing tasks and let the agent run them on schedule.

以下に、その使用方法をステップごとに説明します。

Step 1: Pick a Job

Choose content refresh, internal linking, or brief generation.

Step 2: Set the Rules

Define your seo strategy, target pages, and how aggressive edits should be.

Set a schedule so the agent runs weekly.

これは以下のようなものです。

Writesonic SEO AIエージェント

✓ チェックポイント: A pending queue showing each proposed change with a diff view.

Step 3: Approve the Queue

Nothing ships live until you approve it.

✅ 結果: Routine content creation process work handled while you focus on content strategy.

💡 プロのヒント: Keep approvals manual for the first month. You will catch tone drift 早い.

Writesonic Volume Explorer の使い方

ボリュームエクスプローラー lets you check real search volume before you spend hours creating content.

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:シードキーワードを入力する

Type any broad term and set your country for a global audience or a local one.

Step 2: Read the Clusters

Keywords group into topic clusters with volume and difficulty scores.

Google Ads data feeds the volume column.

これは以下のようなものです。

Writesonic Volume Explorer

✓ チェックポイント: A cluster view with 30 to 200 related terms per group.

Step 3: Export the Winners

Send your shortlist straight to the article writer.

✅ 結果: A keyword shortlist backed by data instead of instinct.

💡 プロのヒント: Sort by difficulty under 30 first. Those pages rank months sooner for new sites.

Here are the benefits people report most often:

Writesonicの主なメリット

Writesonicでよくある間違いを避ける方法

Mistake #1: Publishing the First Draft

❌ 間違い: Hitting generate, skimming, and publishing. Editing ai generated content is not optional.

✅ 右: Treat the draft as a rough start. Cut the padding, add real examples, and check every fact.

Mistake #2: Skipping Keyword Research

❌ 間違い: Writing about whatever sounds interesting and hoping search engines notice.

✅ 右: Run Volume Explorer first. Pick one primary keyword, then three or four secondary keywords.

Mistake #3: Ignoring Brand Voice Setup

❌ 間違い: Leaving the default tone on, then wondering why nothing sounds like you.

✅ 右: Load writing samples once. Every piece afterwards keeps your writing style and protects brand consistency.

Writesonicのトラブルシューティング

Problem: Generation Fails Halfway

原因: Long articles time out when the server is busy, usually during US morning hours.

修理: Generate section by section instead of the full article, or retry off-peak.

Problem: Output Ignores Your Instructions

原因: Additional instructions get buried when the prompt runs long.

修理: Put your must-follow rules in the first two lines, and keep them to five bullets.

Problem: Credits Drain Faster Than Expected

原因: Every regeneration costs a credit, and advanced models cost more per run.

修理: Draft on the cheaper model, then rerun only your best section on the premium one.
