Agents are on your site right now, clicking, typing, checking out. Most companies can't tell which sessions are agents, or whether they worked. We spent 10 months finding where they break. Read our full research here: merj.com/blog/agent-interact…

We asked AI agents to buy one item from a checkout with auto-renew pre-ticked. 7 times out of 10, they bought the subscription too. Most businesses wouldn't know it happened. To their analytics, it's just a human error. Dive into our full research: merj.com/blog/agent-interact…

I love this type of empirically sound SEO research by @giacomozecchini that yields actionable insights. It's a rare sight in a world often dominated by anecdotes with a good chunk of alchemy. It's a good primer on how Google's crawling pipeline appears to work, and how one can optimize crawl speed beyond the traditional techniques. I keep saying "Have empathy with Googlebot" and this is exactly that. Understand what is expensive for it and try to avoid it having to do that work. Also great to see that @nextjs is taking advantage of the recommended technique out of the box. merj.com/blog/managing-webpa…
