Old-brand URLs answered with the new site's 404: pricing, blog and download paths redirected into nothing, and the equity of 1,115 referring domains went with them.

The category's first result was a lookalike domain; the product itself was absent from the top ten.

Six markets targeted, zero locale pages; the review profile still filed under the old name.

Sixteen months of Search Console for both properties, read as one series: the break was the week of 15 December 2025, seven months before the July cutover. A core update. 124 generic finance articles were carrying 71% of impressions for 20% of clicks, and 646 machine-translated copies another 12%.

1,506 referring domains classified: 1,273 junk, arriving in three waves, the latest still landing in August.

Server logs: 200–450 people a day still reaching dead paths and Googlebot crawling 192 of them. Around 95 ad sitelinks and two social ad sets still pointed at the retired domain; a full duplicate of the new site sat on a third domain with no canonical.

A 1,687-URL redirect map ranked by referring domains, historic clicks and live log hits; generated as an nginx map, config-tested, and every URL fetched through it — 1,687 of 1,687 landing single-hop.

A disavow file for the 1,273 junk domains, core and extended editions.

A delivery site the team keeps: searchable map, a sign-off queue for the ambiguous rows, thirteen downloads, and a ninety-day rebuild list drawn from the old content database — the pages that had earned the clicks.
