What I believe

GEO is the new SEO. The shift from traditional search engine optimisation to Generative Engine Optimisation is the defining transition in digital marketing. As AI reshapes how consumers discover products and information, brands must optimise for AI-generated answers — not just blue links.

Retail media is strategy, not a line item. Retail media must be treated as a strategic channel integrated across the media plan — not a checkbox. The brands that win are those embedding retail media into their overall commerce strategy.

Social commerce is mainstream. Platforms like TikTok Shop are genuine commerce channels for mainstream and FMCG brands. Lidl's success on TikTok shows this isn't niche — it's the future of how consumers buy.

AI is rewriting discovery. Artificial intelligence is fundamentally changing how consumers find and choose products. The traffic decline from traditional search isn't alarming — it's a signal that the entire discovery layer is being rebuilt. Brands that adapt their content for this new landscape will capture disproportionate value.
