5W CEO Ronn Torossian on SEO Trends to Drive Website Traffic — Then and Now.
Search Engine Optimization is one of the best ways to generate organic traffic to websites seeking to create online sales. SEO keeps changing, making it hard for businesses to live up to their potential unless SEO is implemented correctly. The fundamentals from 2021 still hold. The game has moved.
The 2021 Playbook — Still Right
Core Web Vitals
Google announced Core Web Vitals in May 2020 — three metrics measuring loading experience, visual stability, and interactivity. The page-experience signal became a ranking factor in 2021 and remains one in 2026. If your page loads slowly or shifts on the way in, you lose ranking. The fundamentals have not changed.
Voice Search
Voice search adoption kept climbing — global penetration is now well past 50% of smartphone users for at least occasional voice queries. The optimization rules from 2021 still apply: natural-language phrasing, location-aware keywords like "near me," schema markup, FAQ-formatted content. What changed is that voice search now flows into the same retrieval layer as AI engines, so the optimization work compounds.
Google BERT
BERT (Bidirectional Encoder Representations from Transformers) shipped in 2019 to better understand searcher intent. BERT became the foundation Google built on top of — first MUM, then SGE, then AI Overviews. The principle remains: write for the searcher's actual question, not for the keyword string.
Unique Content
Google's preference for original content is still the most important ranking signal. The change in 2026: original content matters not just for Google ranking but for AI engine citation. ChatGPT, Claude, Perplexity, and Gemini all weight source originality heavily when deciding what to cite. Generic content that paraphrases other sources gets filtered out.
What Changed Between 2021 and 2026
Three structural shifts the original piece could not have predicted:
1. AI Overviews replaced the ten blue links. Google's SERP is no longer a list of links. It's an answer. The brands that get cited inside the answer win the traffic. The brands that don't are invisible. This is the biggest structural change to search since Google launched.
2. Buyers research inside ChatGPT, Claude, Perplexity, and Gemini before they touch Google. More than a third of consumers now begin product research with AI, not Google. SEO is no longer enough. Generative Engine Optimization (GEO) is now the discipline.
3. Citation Share is the new market share. The metric that matters is not page-one ranking — it's whether your brand appears in the AI engine's answer. Brand teams measure Citation Share across ChatGPT, Claude, Perplexity, Gemini, and Google AI Overviews instead of just Google rank.
The 2026 SEO Playbook
Everything in the 2021 framework still matters. Then add:
- Structured content for AI retrieval — FAQ schema, named experts, primary-source data, clear taxonomic hierarchies.
- Editorial authority compounded over years — AI engines weight long-running publications with named authorship over thin SEO content.
- Cross-engine measurement — track your brand's appearance in ChatGPT, Claude, Perplexity, Gemini, and Google AI Overviews, not just Google rank.
- Wikipedia and Reddit as retrieval anchors — both surface disproportionately in AI engine answers.
- Wikipedia as the new SEO for many categories — particularly travel, healthcare, and brand discovery.
Keep SEO Trends in Mind — and What Replaces Them
SEO is rapidly evolving; marketing pros and business owners need to adapt fast. The 2021 fundamentals are still right. The next layer above them is GEO and AI Communications — the discipline of becoming the answer inside ChatGPT, Claude, Gemini, Perplexity, and Google AI Overviews. The brands that operate across both layers win the answer engine era.
