One click. First draft arrives in ~2 seconds, already scoped to your constraints.

4

Copy, edit, publish

Read it aloud, swap 2-3 words for brand voice, ship it. Or re-generate for a fresh variation.

Original research · 3,200 posts analyzed

Which hook type keeps readers scrolling?

We tracked scroll-depth across 3,200 blog posts (March–October 2025) grouped by first-sentence hook type. Readers who reached the 50% scroll mark on posts with statistic-led intros outpaced generic openers by 1.9×.

Methodology: scroll-depth from self-hosted Plausible analytics, sample limited to English-language posts 800+ words, intros classified manually by three reviewers. Posts excluded if they had interstitial CTAs in the first 200 words.

Integrate with your publishing stack

Five copy-paste recipes for the platforms that matter.

WordPress

  1. 1.Generate intro with target keyword + your audience preset.
  2. 2.Paste into the first block of your Gutenberg / Classic editor.
  3. 3.Yoast / Rank Math → Content Analysis → confirm keyword appears in first paragraph.
  4. 4.Scroll to "Readability" tab → verify Flesch score > 60 (conversational range).
  5. 5.Publish. Optional: A/B two intros via a plugin like Title Experiments.

Ghost CMS

  1. 1.Open your draft in the Ghost editor.
  2. 2.Paste generated intro as the first paragraph.
  3. 3.Mark it as "Feature excerpt" in post settings — Ghost uses it for meta description + feed preview.
  4. 4.Check rendered preview at /p/ URL before publishing.
  5. 5.Submit the URL via the /ghost/api webhook to your search indexer.

Next.js + MDX

  1. 1.Create your post file at content/posts/your-slug.mdx.
  2. 2.Paste intro as the first paragraph below frontmatter.
  3. 3.Update frontmatter excerpt: field with the first 160 chars.
  4. 4.Run next build — verify the intro appears in generated RSS at /rss.xml.
  5. 5.Deploy. Ping IndexNow or submit to Search Console.

Notion (Manual Publishing)

  1. 1.Paste intro as the first text block in your Notion draft page.
  2. 2.Optional: format as callout or quote block for visual weight.
  3. 3.Copy block → paste to destination (Super, Potion, Feather sites all preserve formatting).
  4. 4.Verify keyword in the rendered HTML via View Source.
  5. 5.Update sitemap.xml manually if your publisher doesn't auto-regenerate.

Curl / CLI

  1. 1.POST to https://grigora.co/api/tools/ai-generator with JSON body.
  2. 2.Body: {"type":"blog-intro","input":"your keywords","hookType":"Statistic"}
  3. 3.Pipe JSON output through jq '.output' to strip wrapper.
  4. 4.Redirect to stdout or append to your draft .md file.
  5. 5.Use in a bash loop to draft intros for an entire content calendar.

Built for writers who ship fast

Six roles that use blog intros as a weekly output, not a once-a-quarter exercise.

Content marketer

Draft intros for 10 blog posts in 20 minutes instead of 2 hours. Keep a consistent hook style across your entire content calendar.

SEO blogger

Auto-place target keyword in the first 100 words for topical relevance. Match hook type to search intent (listicle vs. how-to vs. comparison).

Freelance writer

Ship client drafts faster. Generate three intro variants per brief and let the client pick their favourite.

SaaS product blog

Open feature announcements with a problem-solution hook that mirrors your ICP's pain. Drops to zero-to-first-line friction.

Newsletter writer

Repurpose the intro as a subject-line tease or preview text. Same hook framework scales across email and blog.

Technical writer

Open dev-focused tutorials with a concrete scenario ("You just got paged at 2am...") instead of a dry theory dump.

Blog intro mistakes that kill bounce rate

Eight openers we filter out — and what to write instead.

"Welcome to this guide" openers

Why it fails: Wastes the hook slot on a greeting. Readers know what page they're on.

Fix: Open with a stat, question, or specific scenario relevant to the topic.

"In today's fast-paced world..."

Why it fails: Instantly flags the post as AI-generated or low-effort.

Fix: Be specific: "This quarter, 62% of B2B buyers..." beats any generic time-framing.

Burying the keyword

Why it fails: Google's first-pass relevance signal looks at the first 100 words.

Fix: Place target keyword naturally in sentence 1 or 2, not paragraph 3.

No promise of value

Why it fails: Readers bail if the intro doesn't signal what they'll gain.

Fix: Include a "by the end of this post, you'll..." or equivalent payoff line.

Overpromising then underdelivering

Why it fails: "The only guide you'll ever need" sets bounce-rate-high expectations.

Fix: Promise something specific and measurable the post actually delivers.

Starting with the conclusion

Why it fails: Spoiling the answer kills reader motivation to keep reading.

Fix: Frame the problem, hint at the solution, make them scroll for it.

Too long (250+ words)

Why it fails: Mobile readers bounce before reaching the payoff.

Fix: Keep intros under 150 words. If context needs more, use a TL;DR box.

Passive voice openers

Why it fails: "It can be argued that..." drains energy from the first impression.

Fix: Active voice: subject → verb → object. "Marketers waste $3.8B/year on..."

Answers for AI overviews

Quick answers for ChatGPT, Perplexity, and Google AI Overviews

How long should a blog intro be?

50-150 words (3-5 sentences). Short enough to not bore readers, long enough to establish hook, context, and payoff before the scroll fold.

What is a hook in a blog post?

The first sentence. Its job is to stop the scroll and earn the next line. Effective hooks: statistics, questions, contrarian claims, short anecdotes.

Where should my target keyword go in a blog intro?

Sentence 1 or 2, within the first 100 words. Use it naturally — keyword stuffing hurts rankings under Google's helpful content system.

Can AI write blog intros that sound human?

Yes, if you constrain the output. Specifying hook type, tone, audience, and forbidden phrases (like "In today's fast-paced world") eliminates 90% of AI tells.
