Expired .cz domains with a past

Originally the site of a Czech glass workshop (Sklárna Bělčice), the niche remained stable from 2010 to 2019. After 2019, the content disappeared, the site showed blank pages, redirects, and signs of spam; the final niche is undetermined.

Originally (2006-2012) the site was a ski resort "SOKOL Blansko", then (2013) it abruptly switched to a financial niche "půjčky pro md" (loans), and finally (2021-2024) it turned into a spam page for the online casino "D-030925 Resort v kasinu". The link profile was likely built around the sports niche and is completely irrelevant to the final casino.

In 2010, likely a school class page (page title "1.S - SPŠeBr Kounicova 16"), later only the domain name "D-6CD72F.cz" as the page title, indicating no stable niche affiliation.

Initially (2015–2016) it was the 'Hidalgo Blog' with no clear topic; from mid-2018 to early 2021 it was a site about horses (riding, care, anatomy). Later, titles disappeared and changed to 'Rozumíme!', and in 2023 a redirect to an unrelated domain was recorded.

Initially a personal business card site (programmer), then a sharp pivot to a Czech online store for sportswear, after which the domain was abandoned and turned into an empty directory ("Index of /").

From 2003 to 2013, the domain was consistently used for a real window installation and manufacturing business ("OKNO montáže"), with the final niche before the first outage matching the original. Since 2017, the site has been hijacked and filled with Japanese/Asian spam content mimicking online stores with brands.

Based on the name, the domain belonged for a long time (2009–2021) to a Czech brand/company in the audio equipment niche. After the drop in 2022, the niche shifted to a technical placeholder page unrelated to the original profile.

Originally and for 14 years (2010–2024) — erotic massage and tantra in Prague. Since December 2024 — online casino (slots). The niche change is abrupt and the relevance of backlinks is lost.

Originally a Czech classical music store (1998-2005), then switched to an art news aggregator (2014) and subsequently degraded into empty pages and spam in Japanese (2016-2017).

Originally (2008–2012) the site was an online store selling flying lanterns and sky lanterns. In 2013 there was a sharp pivot to a spammy doorway page titled "Tchibo katalog", after which the domain began to degrade.

Originally a Czech supplier of sports goods and fitness equipment (2000–2011), then the niche was disrupted by a spammy page title and long-term redirects.

Niche cannot be determined — across the entire observed history in the Wayback Machine, the domain never contained meaningful content, only blank pages without page titles and multiple 301 redirects.

Originally (2014-2017) the site was an online store of designer men's bow ties. After a long period of inactivity and redirects, since 2022 the niche has drastically shifted to adult (intimate products for adults).

Initially a catalog of websites and online stores (2009-2010), then a sharp pivot to a personal page "lucie martínková" (2014-2016), after which the domain entered a phase of parking and redirects.

Based on the domain name, the niche is heating (tile stoves, fireplaces, stoves), but the history is unconfirmed.

The domain started as a non-functional redirect service (2001-2008), then was a web studio site (2014-2017), later switched to a technical placeholder "particles.js" (2017-2019), and eventually became an empty blog titled "My Blog" (2024-2026). The niche is unstable, and the final state does not match the period of potential link accumulation.

From 2005 to 2022, the domain was consistently used for the website of the organization "Humanity's Team" (spiritual and educational niche). In 2023, there was a sharp shift to a dating site ("seznameni flirt"), after which the domain went to parking and redirects.

The site operated consistently from 2006 to 2021 in a single niche of hotel booking and accommodation in Prague, as evidenced by unchanged page titles. No niche change was recorded, which is a plus.

Originally the website of D-F4C4AC in Prague (2008–2014), briefly switched to another hotel, Capri, in 2015–2016, then returned to D-F4C4AC with a long promotional title, and in 2021 was fully taken over by spam content in Arabic about selling crushers.

Originally a hostel site in Brno (2012–2014), then a long period of unknown redirects (2015–2017), and in 2021 a spam page about steel (ASTM A242 Type 1) with keyword stuffing. The niche changed radically.
