April has been a particularly active month in the search landscape, with continued volatility following multiple Google updates and increasing pressure from AI-driven search experiences. The biggest theme? Authority, trust, and multi-surface visibility (Search, Discover, AI Overviews, and LLMs) are now firmly at the centre of SEO strategy.
Below are five of the most important articles from the past month that highlight where SEO, GEO, and AEO are heading.
Google March 2026 Core Update: What Changed and Why It Matters
Google’s March core update rolled out shortly after February’s Discover update – an unusually tight sequence that caused widespread ranking volatility. The update reinforces a long-standing trend: content quality and E-E-A-T signals are becoming even more decisive ranking factors, with stronger rewards for genuinely authoritative websites and noticeable drops for thin or unhelpful content.
Google’s February 2026 Discover Core Update Explained
For the first time, Google released a Discover-only core update, signalling how important discovery-based traffic has become. Early insights suggest fewer domains dominating visibility, with a stronger emphasis on local expertise and trustworthy content, a clear shift toward entity-level authority rather than just page-level optimisation.
SEO News Roundup: AI Summaries & Search Evolution
AI-driven search continues to expand rapidly, with AI summaries (Overviews) and multimedia search formats gaining prominence. This is changing how users interact with search results, reducing reliance on traditional blue links and increasing the importance of structured, easily extractable content that can surface in AI-generated answers.
Google AI Overviews Are Reshaping Search Visibility
AI Overviews are now appearing in a significant portion of search results, fundamentally shifting SEO dynamics. Success increasingly depends on natural language optimisation, topical authority, and credibility signals, rather than purely ranking for keywords. Brands that structure content for conversational queries are seeing improved visibility in these AI-driven environments.
The Rise of AI-Driven SEO & Generative Engine Optimisation (GEO)
As AI tools like ChatGPT and Google’s AI Mode become primary sources of answers, the SEO industry is evolving rapidly. Marketers are now focusing on visibility across AI ecosystems (not just Google Search), with growing emphasis on third-party mentions, community content, and structured information that AI systems can cite. Traditional ranking signals are still relevant, but no longer sufficient on their own.
If there’s one clear takeaway from April, it’s this: SEO is no longer just about ranking pages – it’s about being understood, trusted, and surfaced across multiple search experiences.
Between core updates, Discover shifts, and the continued rise of AI Overviews, the direction is obvious:
- Build real authority, not just content volume
- Optimise for entities, not just keywords
- Structure content for both humans and machines
Those who adapt to this broader view of search-combining SEO, AEO, and GEO-will be best positioned for what comes next.
