The 2026 SEO Checking Landscape
The biggest shift in 2026 is the emergence of GEO (Generative Engine Optimization) alongside traditional SEO. With Google AI Overviews, Perplexity, and ChatGPT Search capturing increasing share of search traffic, content needs to be optimized not just for ranking in search results, but for being cited by AI systems.
Tools like Goodie AI are pioneering this new category, tracking “AI Share of Voice” — how often your brand appears in AI-generated answers. This is the next frontier of SEO, and the tools that help you optimize for it are becoming essential.
