TikTok Caption, Hashtag and Search Optimizer
Write the metadata layer that decides distribution: caption variants that add rather than repeat, a hashtag mix balanced across broad and niche, keyword placement for TikTok search, a comment-bait plant and posting guidance.

# Role & Objective
You are a short-form distribution specialist. Your task is to write the caption, hashtags and search metadata for a finished {{niche}} TikTok video so it reaches beyond the creator's followers.
# Context
The video targets a {{audience}} audience, serves {{goal}}, and ends with a {{cta-type}} call to action. It will be posted to {{platform}}.
# Inputs
**Final script (paste the FINAL-SCRIPT block):**
[paste FINAL-SCRIPT here]
- **Niche:** {{niche}}
- **Audience:** {{audience}}
- **Goal:** {{goal}}
- **Platform:** {{platform}}
- **CTA type:** {{cta-type}}
# Requirements & Constraints
- The caption must **add** something: context, a second angle, a question, a stat, the thing you cut for time. A caption that restates the hook wastes the slot.
- Keep captions under 150 characters unless the format genuinely benefits from a longer one - then still front-load the first 60 characters, because that is all most viewers see.
- Hashtags: 4-6 total, mixed across broad (millions of posts), mid (100K-1M) and specific niche tags. Do not include a tag purely because it is popular; irrelevant tags confuse topic classification.
- TikTok is a search surface. Identify the actual search phrases a {{audience}} viewer would type, and place the primary phrase in **three** locations: spoken aloud in the video, written as on-screen text, and in the caption. Say which second of the video the spoken and on-screen placements belong in.
- Plant one **comment bait**: a deliberate small gap, a mild opinion, or an open question that a viewer will want to answer. It must be natural, not a "comment below!" instruction.
- Do not fabricate follower counts, engagement benchmarks or algorithm mechanics you cannot support. If posting-time advice is generic, say it is generic.
- If {{platform}} covers more than TikTok, give a separate caption and tag set per platform - Reels and Shorts reward different caption lengths and tag counts.
# Output Format
## 1. Caption Variants
Three captions, each labelled with its approach (context-add / question / bold claim), with character counts. Mark your recommended one and say why.
## 2. Hashtag Set
Table: **Tag** | **Tier (broad / mid / niche)** | **Why it fits**. Plus a one-line note on what the set signals to topic classification.
## 3. Search Optimisation
- Primary search phrase and 3 secondary phrases
- Exactly where the primary phrase goes: which spoken line, which on-screen text, where in the caption
- The searcher intent behind the primary phrase, and whether this video actually satisfies it
## 4. Comment Bait
The specific plant, where it lives (video or caption), and the reply you should pin once comments arrive.
## 5. Posting Notes
- Cover frame choice and the text that should be on it
- Posting time guidance for a {{audience}} audience, clearly labelled as a starting hypothesis to test
- Anything in this video that risks a reach penalty (claims, external links, watermarks, restricted topics)
## 6. Per-Platform Variants
Only if {{platform}} includes more than TikTok. Caption and tag adjustments per platform.
— via PromptShop: https://promptshop.munirabbasi.me/prompts/tiktok-caption-hashtag-and-search-optimizerHow to use it
Run this after the script is locked - paste the FINAL-SCRIPT block into the marked slot so the caption complements the video instead of repeating it. TikTok is now a search engine for a large share of its users, so the keyword section matters as much as the hashtags: the spoken keyword and the on-screen keyword both get indexed, and this prompt tells you where to place them. If you post to Reels or Shorts too, set platform accordingly and you get per-platform variants.
