Search Engine Optimization (SEO), has only been in existence since the late 1990s. In the years since, SEO followed a familiar and easily repeatable playbook: keywords, backlinks, metadata. Today, discovery is no longer limited to links and Google Searches.

In 2020, Google’s market share was well above 90% globally, and the vast majority of all online queries happened there. Today, in 2026, some estimates say that as many as 37% of people use AI primarily for searches instead of traditional search engines.

AI systems summarize, recommend, and answer directly. The question isn’t “How do I rank?” anymore. It’s “How do I become the source AI trusts and cites?”


Old SEO: Optimizing for the Algorithm

Old SEO was built around gaming pleasing the ranking system.

What mattered most:

  • Exact-match keywords
  • Backlinks at scale
  • Meta titles, slugs, and descriptions
  • Page speed and Google's ability to crawl the site

Success meant appearing on page one of Google and capturing clicks. Content was often written for search engines first, humans second. That era rewarded volume and repetition.


New SEO: Optimizing for Understanding

AI-driven discovery has changed the rules.

Search engines now behave more like research assistants. Platforms such as Gemini, Perplexity, and ChatGPT don’t just index pages; they interpret them.

What matters now:

  • Topical authority, not keyword density
  • Clear explanations and structured thinking
  • Demonstrated expertise and real-world insight
  • Consistency across content, platforms, and formats

AI looks for sources that sound confident, specific, and experienced.


The New Visibility Stack

Being “found” now happens across multiple layers:

  1. Search results (traditional SEO still matters, but less on its own)
  2. AI summaries (your content becomes a cited source)
  3. Content recall (AI remembers who is consistently covering a topic well)

If your site explains something better than most, AI will recommend or reference you, even if you’re not #1 on Google.


Write For Humans

It may be AI systems scrolling for answers, but they are being presented to a human audience.

  1. Use clear sentence structure.
  2. Use fact tables, data charts, and visuals. But be sure to keep them machine-readable.
  3. Keep answers succinct but not over-simplified.

Focus on:

  • Writing like you’re teaching a peer
  • Covering topics fully, not just answering one query
  • Showing judgment, not just information
  • Building a recognizable point of view

Aim For Reputable Mentions

If you can earn editorial links, citations from credible institutions or individuals, or references to trusted directories, you are more likely to be ranked as a viable resource by AI.


E-E-A-T

Publish less often, with deeper pages that show Experience, Expertise, Authority, and Trust.


The Bottom Line

Old SEO asked: “How do I rank?”
New SEO asks: “How do I become the answer?”

If your content:

  • Explains things cleanly
  • Reflects lived experience
  • Anticipates follow-up questions

You won’t just be searchable, you’ll be referenced.
