seo: comprehensive SEO/GEO audit — freshness, schemas, crawlers, GEO signals

[elninad]

Summary

Full SEO + GEO audit with 6 files changed, 104 insertions. The site already had excellent foundational SEO — this PR closes the remaining gaps identified in a thorough audit against 2025-2026 best practices.

What changed

Freshness (highest LLM recency-scoring impact)

• All 14 stale 2026-06-15 dates updated to 2026-06-25 across index.html, sitemap.xml, llms.txt, llms-full.txt, ai.txt
• Footer <time> element display updated to "June 25, 2026"

New structured data (index.html JSON-LD)

• Added standalone Occupation schema for the Architect role with full context: responsibilities, qualifications, skill list, location — improves entity disambiguation for LLMs
• Added ReadAction potentialAction to Person schema linking directly to all 4 Medium articles — creates machine-readable signal of published work

New meta tags

• citation_author_email + citation_author_institution — used by academic/AI indexers (Google Scholar signals, Semantic Scholar, Perplexity academic mode)
• fediverse:creator — 2025-2026 GEO signal for IndieWeb/Mastodon ecosystem crawlers
• msvalidate.01 + msapplication-TileColor — Microsoft Copilot / Bing AI search hints

robots.txt — 7 new user-agents

• msnbot, msnbot-media, BingPreview, CopilotBot, Copilot-User — Microsoft Copilot AI search crawler coverage (was completely missing)
• ia_archiver — Internet Archive Wayback Machine (historical crawl authority signal)
• Googlebot-News — explicit news indexing coverage

LLM profile files (llms.txt + llms-full.txt)

• Added "Recent Updates" section to both files with timestamped milestone bullets — LLMs score freshness by explicit changelog signals, not just date headers
• llms-full.txt update includes full context on the 2026 Architect promotion, 2025 article publication, and 2023 AWS cert

Audit findings (pre-PR state)

Signal	Status
Person / ProfilePage / FAQPage / WebSite / Article JSON-LD	✅ Already excellent — 48 FAQ entries, 20 schema items
SpeakableSpecification (voice search)	✅ Already present
SearchAction on WebSite	✅ Already present
VideoObject for YouTube	✅ Already present
robots.txt AI crawlers	⚠️ Missing Microsoft Copilot family
Date freshness across all files	❌ 10 days stale
Occupation schema	❌ Missing (hasOccupation had roles but no standalone Occupation entity)
citation_author_email / institution	❌ Missing
fediverse:creator	❌ Missing
LLM changelog signal	❌ Missing (llms.txt had no "Recent Updates" section)

JSON-LD validation

1 block, 20 schema items, zero JSON parse errors (verified with Python json.loads).

Test plan

• Open index.html locally and verify the footer shows "Last updated: June 25, 2026"
• Run the JSON-LD through Google Rich Results Test — should pass with no errors
• Confirm robots.txt renders correctly at ninadmalvankar.com/robots.txt post-deploy
• Confirm sitemap.xml lastmod dates show 2026-06-25
• Confirm llms.txt "Recent Updates" section is visible at ninadmalvankar.com/llms.txt

Three small things to be aware of before merging:

1. estimatedSalary: null in the new Occupation JSON-LD (index.html line ~2766)
Schema.org validators expect omitted properties rather than explicit null. This won't break anything but is best dropped:

-"estimatedSalary": null,

2. msvalidate.01 value is a placeholder, not a real token

<meta name="msvalidate.01" content="ninadmalvankar" />

Bing Webmaster Tools issues a long hex verification string (e.g. A3F2...). The value "ninadmalvankar" won't verify site ownership with Bing/Copilot — it'll just silently do nothing. If Bing verification isn't set up yet, this tag is harmless but misleading. To get a real token: bing.com/webmasters.

3. fediverse:creator points at X.com

<meta name="fediverse:creator" content="@el_ninad@x.com" />

X/Twitter is not an ActivityPub/Fediverse platform — this meta tag is for Mastodon handles (e.g. @user@mastodon.social). Since there's no Mastodon account, this tag should be dropped rather than pointing at a non-Fediverse domain.

None of these are blocking — the freshness updates, new JSON-LD schemas, robots.txt additions, and LLM file "Recent Updates" sections are all solid. Just flagging so the minor issues don't accumulate.
