Expired domains in construction and renovation

Initially (2012-2014) — a Chinese site about mobile marketing and app development (单仁合强). Then (2016) — a site for an internet marketing training company (单仁资讯). After 2018 — chaotic niche changes: refrigeration equipment, apartment renovation, casino/gambling (百事, 意昂2, HONE-杏宇). Final niche — online casino/gambling platform.

Multiple niche changes: from a corporate site (2016) to watch repair (2016-2018), then to wholesale watch movements (2019), and finally to headphone manufacturing (2022-2026). The final niche does not match the original one, for which the link profile was likely built.

The domain has gone through several niche changes: initially an empty placeholder, then a page titled "16 - Haunted House", later the website of the construction company "D-30A7EBelopers", and since August 2024 it has turned into a porn-spam doorway page with Chinese keywords.

Initially (2010–2017) the domain hosted the D-31AED1 project — a JavaScript template engine. In 2018 the niche shifted to a Japanese site about exterior finishing/painting, in 2019 — to a Japanese adult/dating site, then to the Chinese gambling portal «民彩网» (2019–2020), and before the drop — to a review of the online casino Jet Casino (2021–2022). The final niche does not match the original one for which the links were acquired.

Originally the site was about kitchen door replacement (2013–2014), then shifted to painting and finishing (2022), and by 2025–2026 it turned into Chinese gambling spam (爱体育). The final niche is completely irrelevant to the original and likely built up most of the link profile.

The domain started with technical content (PC repair, router setup), then from 2015 to 2019 was used as a spam doorway in the gambling niche (casinos, betting), and after a series of redirects since 2024 it became a novel-reading site (“万书吧”). The niche changed drastically three times, and the final one is unrelated to the link profile.

From 2011 to 2016, the site consistently existed in the construction and finishing services niche (Chinese company '哈尔滨明朗建筑装饰工程有限公司'). In 2023, an empty page with no page title is recorded, after which, since 2025, the domain has been turned into a Chinese spam resource with casino/betting page titles ('999全讯白菜网', '白菜网站注册大全', '黑黑论坛白菜彩金').

Until 2023-10 — a stable Indonesian business site 'PT D-953352' (importer of generators, construction and agricultural equipment). From 2024-04 the theme sharply changed to Chinese-language gambling/betting brands ('b体育', '乐动'), and in 2025-07 a fake job portal appeared sporadically.

Originally (2018-2020) the domain was used for a stable brand "D-FE7830" without a clear niche focus. Since 2023 the niche changed twice to outright spam: first to a Chinese doorway page (construction materials), then to porn spam with keywords. Relevance to the original link profile is completely lost.

Originally a construction company site (Franklin → Brentwood Construction, remodeling/decks), renamed in 2019 but kept the same industry. After the drop (from 2025), the niche was completely changed to Chinese spam content (gambling/online casino).

Originally (2010–2014) — an English-language site about space, climate change, and financial bubbles. From 2014 — a Japanese site about renovation and remodeling. From 2016 — a Japanese site about mattresses. From 2019 — a Chinese site for a gaming platform (casino). From 2020 — a Chinese site for an online cinema.

Original niche was building materials/trading (D-8C8520 Construction Supplies Trading), but in late 2023 content about essay writing services appeared, and since 2025 the site has fully switched to Chinese VPN/accelerators («雷霆加速器», «火烧云加速器»). The final niche radically mismatches the original backlink base.

Originally a guitar repair site (Mikaleno's Guitar Repair), but since 2025 it has completely switched to a Chinese gambling landing page (sports betting). The topic change is radical, and the final topic is irrelevant to the niche that built the link profile.

From 2008 to 2016 — a stable Hungarian website about website creation ("weboldal készítés"), then a sharp shift to an English-language home remodeling blog ("Home Remodel and Repair Blog") in 2017–2018, after which the domain went through redirects and stopped responding.
