Expired domains in industry and equipment

Originally the site of D-C48E37 Extrusion (industrial extrusion) in 2008–2011, then a long period of blank pages (2014–2019), later switched to a personal blog 'My Wonder World' (2021–2022). The niche changed drastically, and the final one does not match the original, which received the bulk of the link profile.

From 2008 to 2015, the domain was used as the corporate website of "A.K. Co., Ltd" (likely a manufacturing or trading company). After a long period of 301 redirects (2016–2021) and downtime, since 2025 the domain has been taken over and filled with blatant spam adult content in Chinese.

Abrupt niche changes multiple times: industrial alloys (2013-2015) -> Japanese health/beauty blog (2016-2017) -> casino (2018) -> porn (2019) -> casino in Portuguese (2025). The original niche is completely lost; the current one is spam casino.

Originally (2018–2022) the site was for Perkins Automation, likely related to industrial automation. In 2024, the niche abruptly shifted to a Chinese online casino (gambling), after which the domain showed an empty page title and went to a redirect.

Initially a site about metalworking and industrial parts (2011–2013), then repeatedly changed: spam service for fake documents (2014), sports app (2014), again industrial theme with keyword stuffing (2017–2019), redirect to an unknown destination (2021), and finally — Chinese casino/betting (2023).

From 2011 to early 2021, the domain consistently hosted a Czech-language site dedicated to the cultural event 'Husova pouť'. In August 2021, the niche abruptly shifted to an English-language spam doorway page 'New Potash Feldspar Briquette Making Machine Price', after which the domain stopped serving content and began redirecting cyclically to itself.

Originally (2015–2019) the domain was used for the brand of a transport and forwarding company "D-73FB30®". In 2022, the niche was radically changed to industrial spam content (keywords about quarry crushers and drying machines).

Consistent niche of handmade chili sauce production (sečuánský chilli oil) from 2022 to 2024. After the drop (2025), the domain is used as a registrar parking page.

The domain has repeatedly changed niches: from web hosting and IT services (2007) to massage equipment, gifts, private game servers, abortion spam, adult content (2020–2022), and finally to an investment company site (2024). The final niche does not match the bulk of the backlink profile built up over the domain's lifetime.

The site changed its niche twice within Chinese industrial equipment (mesh fencing → construction protective canopies), page titles contain massive keyword stuffing. After 2021, it went into an IIS placeholder state, then to a 301 redirect.

From 2004 to 2015, the site consistently represented a halal meat production business (D-B0AF67, 100% Zabiha Halal). Since 2015, the page titles switched to generic templates, and from late 2019 the niche was destroyed — content disappeared, redirects to archived copies and empty pages began.

Originally the site of a Chinese auto parts manufacturer (2018-2019), then hijacked and turned into a casino doorway (九游会老哥俱乐部 — Jiuyouhui Casino, 2022), after which it went dark with empty page titles, redirects, and placeholder pages.

From 2011 to 2016, a stable site of a Chinese CNC machine manufacturer with over-optimized page titles; after a gap, in January 2022, the domain turned into a one-pager for betting on the 2022 FIFA World Cup.

Originally the site of the Iranian company «جنرال استیل البرز» (General Steel Alborz), later renamed to «تهران آذیه» (Tehran D-E2175D); the niche remained within a corporate/industrial site, with no sharp niche shifts (spam, casino, etc.) recorded.

Originally the site of a local radio station, 'Wilmington's Big Talker FM' (2017–2021). After the drop, the domain was listed for sale, then briefly became a site about personalized nutrition (2024), and since late 2025 has been used for a Chinese industrial resource (auto components). The niche has changed radically and repeatedly.

Initially, the site was dedicated to the production of T-shirts and polos (D-6E81B4, konveksi polo shirt) — an Indonesian light industry niche. In 2023, the domain abruptly shifted to a Chinese online casino (亿电竞平台官网 — 'official website of the esports betting platform').

From 2020 to mid-2025, the domain hosted a manufacturer of industrial equipment (Quanzhou YueLi Automation Equipment) with page titles about drilling/tapping machines. Since September 2025, the final niche shifted to Chinese spam/casino content («极速赛车», racing/lottery gambling), unrelated to the original profile.

Multiple niche changes: adult (2021-2022) → industrial equipment (2022) → blank page (2023) → Macau gambling/lotteries (2024-2025). Final niche is a typical spammy doorway page with keyword stuffing.

Multiple niche changes: initially, likely a Chinese site about climate testing equipment (2008-2013), then casino/gambling (2015), then equipment again (2017), and since 2022 — exclusively pornographic content. The final niche is completely irrelevant to the original one.

Originally a photo gallery (2005–2007), then a sharp pivot to a printing equipment site (2008–2009), followed by years of redirects (2012–2018), and after re-registration, back to a photo gallery (2019–2022). Final niche is photography, but the link profile is likely mixed and irrelevant.
