Claude just merged Chat and Cowork — the decision that disappeared, and the caveat that didn't

Chat and Cowork are now one conversation with a full agent runtime underneath. What changes for operators: no more routing, deliverables inside the chat — and the local-tasks caveat most coverage skips.

Cloudflare now lets you block AI training on your website — without disappearing from AI answers

Cloudflare's new AI Crawl Control splits one blunt setting into three switches: search, AI training, and AI agents. What the Sept 15 update changes for anyone publishing content.

Nineteen days of ad spend with no measurement: the Google Tag Manager snippet was gone from the page, not broken in the console

A purchase conversion sat at zero for nineteen days. The container was fine - the snippet had been removed by a deploy. How to pin the hour without backend access, why you must tell Smart Bidding its data is wrong, and the fourteen-day cap that makes fast detection worth money.

How to read a competitor's channel mix from the outside: the low-cost stack I use before trusting an internal narrative

Someone will tell you a competitor is outspending you. Ask how they know. Most of what a competitor does in advertising is now public by law. Here is the low cost stack, the spend triangulation and the error bars that make an outside-in read defensible.

I built a client performance dashboard in a day with Claude Code — the hard part was not calling enquiries revenue

A lead-generation business that takes no payment online. Four APIs disagreed with their own documentation, but the decision that mattered was what to call the biggest number on the page.

The channel filter on my dashboard silently broke ROAS: how to attribute ad spend across sales channels

Revenue filtered, ad spend didn't, and the ROAS card sat there unchanged looking authoritative. Ad spend is tracked per advertising channel, revenue per sales channel — here is the attribution rule and the invariant that catches it.

My scheduled Meta CAPI consent audit found a missing cookie banner, not a tracking bug

A weekly Claude Code routine flagged one market at 0% of orders reaching Meta. The consent banner had never rendered there at all — so the pixel fired on every visitor with no way to refuse.

Three ways in, none of them a funnel. We were counting like there was only one.

A retailer reported one enquiry type and had three. Counting all of them cut cost per enquiry by a third without changing a thing — and the ripest route turned out to be the one least dependent on ads.

I named the cookie the obvious thing. So had the script that was already there.

My attribution cookie collided with the one the site already had — and it overwrote it precisely on paid clicks. A postmortem on naming, namespacing, and being your own first suspect.

The lead went out to a company. It had been struck off the register two years earlier.

One undeliverable lead led me to sweep 830 directory listings against the commercial register. Sixty-eight of the companies were deleted or in liquidation.
