Content & Marketing Prompt Builder

14: Ad copy, Blog outline, Case study, Cold email, FAQ generator, LinkedIn post, Newsletter, Podcast outline, Press release, Reel script, SEO article, Storytelling, X (Twitter) thread, YouTube script. Pick one at the top of the tool; the page link updates (for example ?v=ad-copy) so you can bookmark or share that exact view.

Google Ads responsive search ads allow up to 15 headlines of 30 characters each and up to 4 descriptions of 90 characters each. Because Google mixes and matches assets, every headline must make sense on its own — the prompts generated here instruct the AI to write standalone headlines and to report the character count of each one.

A workable range is roughly 120 to 500 words per H2 section: below about 120 words a section cannot develop a point, and above about 500 readers lose the thread. This tool divides your body word budget evenly across sections and warns when the result falls outside that range.

The most common structure is Problem–Solution–Result: client background, the problem and its business cost, the approach step by step, then quantified results. Two well-known alternatives are STAR (Situation, Task, Action, Result), popular in consulting and interviewing, and Challenge–Solution–Impact, common in B2B marketing decks. This builder outputs a section-by-section outline for whichever you pick.

Roughly 50 to 125 words. Boomerang's analysis of millions of email threads found response rates peaked in that band and fell off on both sides, and 100 words is about 25 seconds of reading at the average adult silent reading rate of 238 words per minute. This builder budgets the opener, value section and ask inside whatever total you set and warns you when you leave the band.

Around 40 to 60 words if you want the answer to be quotable as a featured snippet, and up to about 120 words when the question genuinely needs detail. Lead with the direct answer in the first sentence — the supporting explanation after it is what gets truncated, and that is fine.

A standard LinkedIn feed post is capped at 3,000 characters; LinkedIn articles are a separate, much longer format. This tool sizes the whole hook-story-takeaway structure to a target you choose between 200 and 3,000 characters.

Keep it to about 40 characters. Mobile mail clients — where most opens happen — truncate subject lines around 30 to 40 characters, with iPhone Mail in portrait being the usual worst case. This tool writes that 40-character ceiling directly into the drafting prompt.

Around 10 to 15. A substantive answer plus a follow-up runs 2-3 minutes, and a 60-minute episode has roughly 55 minutes of segment time after the open, intro and outro. This tool does that arithmetic for your exact runtime and warns when the plan gives each question less than 2 minutes.

300 to 500 words — the one-page convention wire services and newsrooms have used for decades, which reads in about 75 to 125 seconds at the average silent reading rate of 238 words per minute. This builder accepts 200 to 800 words and warns you when you fall outside the 300-500 range, because past 500 words a release stops being something a journalist skims.

About 3 seconds or less. Creator guidance from Meta and TikTok consistently reports that viewers decide whether to keep watching within the first ~3 seconds, so the hook line and its visual must land inside that window — this tool locks the hook beat to a maximum of 3 seconds regardless of total runtime.
