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.

Here's what we found.

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.

Session isolation may be a factor as well. JetOctopus stores more than one session in IndexedDB local storage.

Today at 3pm (GMT), join our SEO engineering webinar. It's a deep dive into how businesses should set up session isolation correctly for web crawlers.

🗞️Research article: merj.com/blog/validating-ses…
🗞️Does your business rely on data from web crawlers for campaigns, decision making and machine-learning inputs? In this research, @giacomozecchini shared 6 tests that were performed across 14 popular crawling providers.
merj.com/blog/validating-ses…
The tests were for...
Storage Isolation:
1. Cookie
2. IndexedDB
3. LocalStorage
4. SessionStorage
Cross-tab communication:
5. Broadcast Channel
6. Shared Worker
We provide a Docker container which contains the full crawl testing framework so that all web crawling providers can benefit from the research

Does your company rely on a web crawling platform as a data source to make business decisions, machine learning, or manage risk?
@giacomozecchini will deep dive into how web crawlers should be isolating sessions correctly and the effects of not doing it.

After yesterday's @webperfwg discussion about exposing bfCache eligibility/issues through an API, waiting for that to be spec and implemented, I've written this thing to automate the bfcache eligibility test: gist.github.com/giacomozecch…
I can think of few things as marvelous as a shout out in the Year in Search Central 2021 recap from the magical @g33konaut alongside @giacomozecchini, @davewsmart, @bart_goralewicz, and @TomekRudzki
