Make AI video ads discoverable: demand on-screen text, transcripts and VideoObject metadata in your creative brief to boost organic reach.

Beat low organic visibility: craft SEO-friendly creative briefs for AI video ads

Agencies and in-house teams are producing more AI video ads than ever — but most briefs stop at creative direction. The result: visually strong ads that never surface in organic search, fail accessibility checks, or underperform on discovery platforms. This brief shows how to instruct AI tools and production partners to include on-screen text, rich metadata and deliberate asset variations so your AI video ads are both discoverable and accessible in 2026.

Why this matters now (2026 context)

By late 2025 nearly 90% of advertisers were using generative AI for video creative. Adoption is commoditised — performance now depends on the inputs, measurement and how videos are indexed by search and AI answer engines. Search engines and AI assistants increasingly rely on transcripts, on-screen text and structured metadata to surface video answers (Answer Engine Optimization or AEO). If your brief doesn't mandate these elements, your ads may be invisible to the very discovery systems that drive organic traffic.

Practical takeaway: Treat video creative as content that needs SEO engineering as much as design — include on-screen text, transcripts, and schema in the brief.

What an SEO-friendly AI video brief must specify

The creative brief acts like a contract between strategy, production and the AI tooling. Below are non-negotiable sections that ensure videos are indexable and accessible.

1. Primary objective and target KPIs

Primary goal: e.g. Increase organic assisted conversions from video by X% in 6 months.
Discovery KPIs: organic impressions, branded and non-branded search CTR, video SERP appearances, watch time, engagement rate.
Accessibility KPIs: caption accuracy & WCAG compliance score, audio description availability.

2. Target audience & search intent

Specify commercial intent keywords and questions the video must answer (for AEO). Include short list of high-value UK queries and intent anchors — e.g. "best small business accounting software UK", "how to install X", or brand + value proposition. These phrases should appear as spoken lines, captions and in video metadata.

3. On-screen text (OST) and transcription rules — mandatory

On-screen text is now one of the strongest signals for indexing short-form video content. Your brief should instruct AI systems to produce OST in tandem with spoken copy and transcripts.

Text variants: Include the full headline, short punchline and key benefits as OST. Use variants for 16:9, 9:16 and 1:1 crops.
Consistency: OST must exactly match the transcript for primary keyword phrases to reduce mismatch signals.
Burned-in versus selectable captions: Provide both — burned-in OST for discovery (some scrapers parse pixels) and separate VTT/SRT captions for accessibility and indexing.
Searchable overlays: If you use dynamic scene metadata (time-coded keywords), include a JSON sidecar with scene-level captions and keywords.

4. Metadata & structured data — required deliverables

Metadata is how search engines and AI agents find and present video content. The brief must require specific deliverables:

Transcript (plain text) and SRT/VTT files.
JSON-LD VideoObject snippet with title, description, uploadDate, duration, thumbnailUrl, contentUrl, embedUrl, publisher and keywords. Include sceneStartTimes if possible. See notes on structured data and indexing.
Descriptive filename and alt text for thumbnails and posters (use target keywords).
Open Graph & Twitter/X tags — og:video, og:image, og:description, twitter:player if embedding.
Video sitemap entry or inclusion in existing sitemap.xml with lastmod and platform tags — include a canonical video sitemap entry for each publish page.

5. Accessibility requirements

Accessibility is not optional — it affects indexing and is legally required for many public-facing sites in the UK. The brief should demand:

Accurate captions (99%+ word accuracy target) with speaker labels and sound cues.
Audio descriptions for videos longer than 60 seconds or where visual info is core to meaning.
Contrast and font-size standards to meet WCAG AA (minimum contrast ratios, 14–16px visual text on mobile).
Keyboard-accessible player controls and visible focus states.

Asset variations: how to brief AI for discoverability across platforms

One master video is not enough. Your brief must produce asset variations purpose-built for SEO, platform discovery and reuse.

Essential variations to request

Aspect ratios: 16:9 (YouTube/website), 9:16 (TikTok/Reels/Shorts), 1:1 (feed), 4:5 (Instagram feed).
Lengths: 6s (bumpers), 15s (ads), 30s, 60s, full version.
Text-first versions: Videos where OST appears immediately and persists for the first 3–5 seconds for mute autoplay environments.
Audio-only assets: Podcast-friendly cuts and full transcript for republishing.
Textless masters: Clean master without text for localised edits and A/B creative tests.
Language/localisation: English (UK) primary, plus translated OST and subtitles for key markets.

Why variations drive organic reach

Different platforms and search features prefer different signals. Google Discover and AI answer engines often use short, caption-first clips and thumbnails with readable text. Creating these variations upfront reduces post-production time and ensures each asset includes the SEO signals needed to be surfaced.

Practical checks and validation — include a QA checklist in the brief

Make validation part of delivery. Add a checklist vendors must complete before handover.

Transcripts and SRT/VTT attached and timecodes aligned with OST.
JSON-LD VideoObject present on the landing page and validated with Schema Markup Validator.
Open Graph and Twitter tags present and tested with the social card debugger tools.
Video thumbnail uses keyword-rich filename and alt text; still image is 1280x720 or higher for YouTube.
Accessibility pass: captions accuracy, audio description file present if required, contrast checks passed.
Page performance: video does not block LCP and is served via CDN or lazy-loaded; Core Web Vitals assessed.

Tools to use in QA

Google Rich Results Test & Schema Markup Validator for structured data.
Lighthouse / PageSpeed Insights for page performance and accessibility checks.
VTT/SRT editors (Subtitle Edit, Aegisub) for caption verification.
Social card debuggers: Facebook Sharing Debugger, Twitter Card Validator.
Automated transcript services (with human QC) — e.g. Descript, AWS Transcribe + human review.

WordPress and CMS implementation checklist (SEO tools & plugins)

Most agency clients host landing pages or blog posts on WordPress. Include these CMS-specific instructions in the brief.

Required WP setup

Host video files on a performant CDN or use a streaming provider (ensure CORS and embed compatibility).
Use a schema plugin (Rank Math, Yoast, or Schema & Structured Data for WP) and paste the JSON-LD VideoObject on the page template.
Generate and submit a video sitemap (plugins exist or generate server-side) and list platform-specific tags where needed.
Embed SRT/VTT files via accessible HTML5 player (e.g. Video.js with accessibility plugin).
Ensure thumbnails use responsive srcset, descriptive alt text and filenames with target keywords.
Lazy-load non-critical video embeds; defer heavy JS so LCP isn’t impacted.

Example JSON-LD snippet to request

Please include this kind of JSON-LD in deliverables (adapt content values):

{
  "@context": "https://schema.org",
  "@type": "VideoObject",
  "name": "[Target Keyword Headline]",
  "description": "[Short description with target keywords and user intent].",
  "thumbnailUrl": "https://example.com/thumb.jpg",
  "uploadDate": "2026-01-12",
  "duration": "PT0M30S",
  "contentUrl": "https://cdn.example.com/video-30s.mp4",
  "embedUrl": "https://example.com/embed/video-id",
  "interactionStatistic": [{
    "@type": "InteractionCounter",
    "interactionType": "https://schema.org/WatchAction",
    "userInteractionCount": 3421
  }],
  "publisher": {
    "@type": "Organization",
    "name": "Example Ltd",
    "logo": { "@type": "ImageObject", "url": "https://example.com/logo.png" }
  }
}

Prompting AI tools: exact language for briefs

When briefing AI creative engines (video LLMs or multimodal models), be explicit. Below are prompt fragments you can paste into your brief or vendor form.

Prompt: OST, captions and transcript

"Produce a 30s promotional video in English (UK). Include burned-in on-screen text that matches the final transcript exactly. Export a plain text transcript and VTT file. Key phrases to include verbatim in OST and transcript: [list target keywords]. Ensure captions show speaker labels and sound cues. Deliver 16:9, 9:16, 1:1 crops with OST adapted for each crop."

Prompt: Metadata and schema

"Create a JSON-LD VideoObject with unique title and description (use target keywords), supply thumbnail URL and contentUrl, and produce a short SEO-friendly page description (150–160 characters). Provide a canonical filename and alt text for the thumbnail image."

Prompt: Accessibility

"Generate caption files with 99%+ accuracy. Produce an audio-description track where the narrator describes non-verbal visual cues. Confirm OST contrast ratios and readable font size on mobile."

Case study: how a brief lifted organic discovery (real-world format)

Summary: A UK SMB client used AI to produce 30s demo videos but saw zero organic traffic from video search. We rewrote the brief to require OST, scene-level keywords, JSON-LD and VTT captions. Within 90 days the videos appeared in the Google Video carousel for target non-branded queries and organic video-assisted conversions rose 28%.

Actions taken:

Added burnt-in keyphrases + exact-match transcripts to remove signal mismatch.
Implemented VideoObject JSON-LD and added video sitemap entries.
Delivered platform-specific clips with captions and tested social cards.

Results:

Video SERP impressions up 320% for target queries.
Organic video-assisted conversions increased by 28% inside 90 days.
CTR from video-rich results improved by 18%.

Common pitfalls and how to avoid them

Pitfall: OST that contradicts transcript (confuses crawlers). Fix: enforce exact-match requirement in brief.
Pitfall: Relying only on platform closed captions — some scrapers don't access them. Fix: also provide burned-in text and sidecar SRT/VTTs.
Pitfall: No schema or sitemap — search engines miss the cue to index. Fix: require JSON-LD VideoObject and sitemap entry on every publish page.
Pitfall: Single aspect ratio only. Fix: request variations up-front with OST adapted to each crop.

Template: SEO-friendly AI video creative brief (copy this)

Use this template as the body of your brief or a project intake form.

Project name —
Objective & KPIs — Define organic impressions, CTR and conversions targets.
Target queries & user intent — List primary keywords and question-style queries for AEO.
Format & durations — 30s, 15s, 6s; crops required: 16:9, 9:16, 1:1.
On-screen text — Provide headline, subhead and 3 benefit lines. Require exact-match transcript and burned-in OST.
Captions & transcripts — Deliver .srt/.vtt and plain text transcript; caption accuracy target 99%.
Metadata — JSON-LD VideoObject, plain description (150–160 chars), thumbnail filename and alt text.
Accessibility — Audio description, WCAG AA contrast and font size, keyboard controls.
Delivery — CDN links, master files, platform-specific assets and sidecar metadata JSON.
QA — Schema validation, Lighthouse accessibility, social card previews, captions check.

Future-proofing: trends to watch in 2026 and beyond

Expect AI indexing to get more sophisticated: scene-level understanding, optical character recognition (OCR) over video frames and deeper integration of video objects into AEO answers. Governance and hallucination control will also tighten — meaning briefs must include factual verification steps and source attribution for claims shown in video.

Two quick predictions:

Search engines will increasingly use burnt-in text and scene OCR to extract answers from short-form clips — OST will be a primary indexing signal for short videos.
AEO optimisation will require fine-grained, time-coded metadata. Briefs that include scene keywords and timecodes will outperform generic video assets.

Final checklist: what your brief must include (one-page summary)

Objective & target SEO/AEO KPIs
Target queries included in transcript, OST and metadata
Burned-in OST + SRT/VTT captions + plain transcript
JSON-LD VideoObject + video sitemap entry

QA: Schema validation, social card tests, Lighthouse
WordPress/CMS implementation notes: CDN, schema plugin, player config

Conclusion & call to action

AI makes video production faster, but it doesn’t replace structured thinking. The briefs that win in 2026 are the ones that treat video as content engineering: explicit OST, robust metadata, accessibility-first assets and platform-ready variations. Add this discipline and you’ll turn AI video output into a sustained organic traffic channel rather than a short-term ad spend tactic.
