I study the system that produces them.** Most search advice is recycled opinion. I would rather test it on real products, at real scale, and publish what holds up, including what does not. Google and AI assistants like ChatGPT are changing how people find things. The teams that understand how they work early will own the next decade of discovery. ## Contact - Book a 30-min call: https://calendly.com/tanuj-marketingpal/30min - Email: tanuj@marketingpal.co - LinkedIn: https://www.linkedin.com/in/tanuj-sharma-a7430037/ - MarketingPal: https://marketingpal.co
