Content Gap Analysis

TF-IDF cosine similarity analysis across 6 high-value keywords. 25 competitor pages scraped and vectorized. Proving content weakness — not authority weakness.

March 13, 2026

Executive Summary

The problem is content,
not authority.

Synthesia.io has every signal of a high-authority domain: DR 75+, Fortune 100 customers, strong branded search. Yet they rank for only 1 of 6 core product keywords.

Two target pages don't exist — "script to video" and "AI voice cloning" return 404
Three existing pages are thin — Interactive app UIs with minimal indexable text. TF-IDF shows 0.058 avg cosine similarity to ranking content
Lower-authority competitors outrank consistently — Pictory (DR ~40), Crreo (DR ~15), notegpt.io (DR ~25)

The fix: Create the two missing pages, add substantial indexable content to the three existing ones. A content operations problem AirOps is built to solve.

The Evidence

Content gap,
not authority gap.

✅ Authority Signals (Strong)

DR 75+ — strong backlink profile
Trusted by 90% of Fortune 100
1M+ users, 50K+ companies
Ranks #3 for "AI avatars" — Google trusts this domain
High branded search volume, $156M+ funding

❌ Content Signals (Weak)

2 of 6 target pages return 404
Live pages are JS app shells — minimal indexable text
0.058 avg cosine similarity to SERP content
Missing critical topical terms competitors cover
No FAQ sections, no comparison tables, no how-to content

Recommendations

Action plan
to close content gaps.

🔴 Priority 1 — Create Missing Pages (Week 1)

"script to video" — Create /features/script-to-video

Currently 404. Canva (#1, 1,901 words), Pictory (#2, 1,790 words) dominate
Target: 1,500-2,000 words with how-to, use cases, comparison, FAQ

"AI voice cloning" — Create /features/ai-voice-cloning

Currently 404. ElevenLabs dominates (#1, 2,073 words)
Synthesia HAS this feature — just no landing page

🟡 Priority 2 — Enrich Existing Pages (Weeks 2-3)

"text to video" — Page exists, not ranking

App shell UI with minimal indexable text. Add 1,500+ words below the tool

"explainer video maker" — Page exists, not ranking

Same issue. Adobe (#1), Videoscribe (#2, 5,066 words) have rich content

"AI avatars" — Ranking #3, vulnerable

0.058 cosine similarity — ranking on authority, not content quality. At risk.

🔵 Priority 3 — Listicle Strategy (Ongoing)

"best AI video generators" — Editorial keyword. Zapier (9,256 words!), Reddit, CNET dominate. Pursue listicle inclusion + create /compare pages for long-tail.
