What counts as YouTube metadata?

YouTube metadata includes your title, description, tags, chapters, language, captions, category, thumbnail, and basic file info. Algorithmically, the title + thumbnail combo drives CTR, while description, chapters, and captions help relevance.

Signal vs. noise
Tags, filenames, and minor fields can help discovery, but don’t compensate for a weak title/thumbnail or poor retention.

Do / Don’t

Quick checklist

  • Do match the promise in first 10s of the video.
  • Do keep ~60–70 chars; front-load keywords.
  • Don’t clickbait — retention will tank.

Descriptions that drive CTR & search

Template (first 3 lines visible)

Hook in 1 sentence + primary keywords.
Value statement + who this is for + timeframe (2025).
Chapters below ↓  Links after chapters ↓
Chapters tip
Put chapters right after your hook. Avoid link walls above them; keep the top clean for search snippets.

Tags & filename value

Tags help with synonyms and misspellings (minor ranking weight). A readable filename is fine but not a ranking lever. Focus on title/thumbnail/retention first; use tags for variants like “yt metadata”, “youtube seo metadata”.

Benefits

UX & search

Better retention, scannability, and eligibility for “key moments” in Google results.

Thumbnails: specs & privacy

Specs that age well

Safe defaults

  • 1280×720 (min), 16:9, <2 MB, JPG/PNG
  • High contrast; readable at 2–3 cm on phone
  • Face + verb or outcome word often lifts CTR

Privacy hygiene

EXIF/GPS clean

Strip GPS and device metadata from your thumbnail files before upload.

# CLI fallback if needed
exiftool -overwrite_original -GPS*= -Artist= -SerialNumber= "thumbs/*.jpg"
Prefer a privacy-first, browser-only cleaner MetaRemover.com. Local processing, no uploads.

Captions, languages, and search

Upload accurate captions (SRT) to improve accessibility, search coverage, and viewer satisfaction. Translate popular languages for regional discovery; set your video language and title/description translations where possible.

Shorts-specific notes

  • Think “headline thumbnail” in the first second; the frame is your thumbnail.
  • Keep titles punchy; hashtags optional and situational.
  • Chapters not used; rely on on-screen text cues.

Upload presets & templates

Description templates

Speed + consistency

Create channel-level defaults: hook placeholder, chapter scaffold, social links at the bottom, and a disclosure line when needed.

Checklists

Upload routine

  • Title ≤70 chars, outcome-specific
  • Hook + chapters in first 3 lines
  • Thumbnail contrast checked on mobile
  • Captions uploaded; language set

Verify with ffprobe/ExifTool

ffprobe (video/container)

Before upload

# Inspect video/audio streams & container tags
ffprobe -hide_banner -v error -show_format -show_streams "video.mp4"

Confirm codec, bitrate, and that no odd private tags remain.

ExifTool (thumbnails)

Privacy sanity check

exiftool -G -a -s "thumbs/*.jpg"
exiftool -overwrite_original -GPS*= -Artist= -SerialNumber= "thumbs/*.jpg"
