SEO has a new vocabulary in 2026.
A few years ago, the conversation was mostly rankings, links, CTR, technical SEO.
Now we’re also talking about:
AI Overviews.
AI visibility.
Fan-out queries.
Retrieval.
Grounding.
Entity recognition.
Corroboration.
Brand authority.
And the challenge is that all of these now sit inside the same search ecosystem.
So we mapped the terms we think matter most into one SEO Periodic Table for 2026
A quick way to see how modern search is actually being built:
🔴SEO Foundations
SEO → Search Engine Optimization
SERP → Search Results
CTR → Click-Through Rate
URL → URL Structure
🔵Technical SEO
XML → XML Sitemap
IL → Internal Linking
CWV → Core Web Vitals
CRL → Crawlability
IDX → Indexation
SCHEMA → Structured Data
🟣 Content & Optimization
EEAT → Experience, Expertise, Authority, Trust
IG → Information Gain
RAG → Retrieval-Augmented Generation
QFO → Query Fan-Out
CIT → Citation
RET → Retrieval
ENT → Entity Recognition
🩷Authority & Brand

BL → Backlinks
TR → Topical Relevance
SRC → Trusted Sources
COR → Corroboration
BA → Brand Authority

🟢Metrics & Reputation

🩵Emerging AI Concepts
AGT → AI Agents
ZC → Zero-Click Search
MSO → Multi-Surface Optimization
LLM → Large Language Model

The bigger takeaway?
SEO isn’t being replaced. It’s being layered.
Rankings still matter.
Technical foundations still matter.
Links still matter.
But now retrieval, citations, third-party authority, entity recognition and AI visibility sit on top of them.
Save this one for the next time someone throws another SEO acronym into the meeting.
