Guides & resources

Learn SEO

Six topic hubs: structured data, ecommerce and Merchant Center, technical SEO, international SEO, AI search, and original research. Each one collects the guides, notes and tools for that subject. Written at various hours of the night by someone who's been in the validator, in the Search Console, and in the meeting where someone asked 'so why didn't we just run ads?'
