Expired .net domains in education and courses

Originally and for most of its life (2017–2023), the site was dedicated to photographing high school football matches in Fukuoka Prefecture (Japan). After the drop and auction (since 2024), the niche changed to an undefined one ("D-FB582F"), which most likely does not match the niche of the football photo blog that built the links.

The site existed steadily from 2011 to 2018 as a Japanese resource for finding and comparing schools/after-school classes for children ("子供のお稽古事"). No niche change was recorded; the final niche before the long downtime fully matches the period of backlink growth.

Originally (2003–2008) the site was dedicated to aviation training (“unusual attitudes require unusual training”). From 2010 to 2026 there was no content (empty page titles, likely domain parking), and the final title “Elevate Your Brand” indicates a shift to marketing/branding.

Stable niche of the East Lake High School school newspaper ("The Talon") from 2011 to 2022. Since mid-2023, the niche shifted to parking with German-language content ("Informationen zum Thema D-6ABFB8"), then to an empty placeholder.

From 2002 to 2020, the site consistently represented a high school cross country team (Palatine High School Cross Country). After a period of parking on BlueHost (2020–2022), the domain was hijacked and filled with Chinese gambling content (2023–2024).

Stable niche of music production and training (Sound Producer) from 2019 to 2022. After 2022, the site degraded: page titles became empty or incomplete, and content likely disappeared.

Initial niche not identified (parking, empty page titles); in 2017 — a Persian site about online learning («معلم آنلاین»); since 2020 — a Japanese site that shifted from a personal/business blog («結～ITOYOSHI～») to D-E5376Ees on traditional culture («伝統文化 オンラインクラス»). The final niche only partially matches the domain's niche (D-E5376E).

Originally a site about books and publishing (2005-2007), then abruptly shifted to a resource for preparing for entrance exams to Japanese universities (2007-2019). The final niche before the drop was educational, which likely attracted the bulk of the backlinks.

From 2005 until approximately 2017, the site was dedicated to a personal practice of "healing" and meditation (I am Healing / フルフィルメント瞑想), after which it shifted to a commercial meditation school site in Tokyo ("瞑想スペースSOMA"), which remained active until 2022.

Stable Japanese niche focused on job placement for graduates of vocational schools (D-3F9B67) from 2018 to 2023, with no niche changes.

From 2006 to 2016, the domain consistently operated as the website of the Chinese language school "ハンズアカデミー" in Shibuya (Tokyo). After 2017, the niche shifted to a personal blog "Snow Mail -Kyoko's Blog-", then to an article about an aesthetics salon in Sendai, and by 2020 — to a Chinese store; in 2025 — an empty page/redirect.

No obvious niche changes detected (0 times). From 2021 to 2022, the site was positioned as "D-26FBFE – The Exceptional Education Technicians" (education-tech/recruiting niche). From December 2023 to May 2024, the page title was simply "D-26FBFE.net" (likely domain parking), and from July 2024 to 2026, it was "D-26FBFE -" (brand without a descriptive part). The final niche, based on the title, remained within the brand, but relevance to the historical link profile is not confirmed.

From 2013 to 2021 — the site of a language school in Rennes (courses in English, German, Spanish). The niche is stable, with no changes. Since 2022, the page title has changed to just "D-0587A6.net", indicating domain parking or an empty placeholder after the drop.

Originally (2005–2014) a stable educational site (Region 4 Education Service Center). Since 2014, the niche disappeared, the site turned into a content-free placeholder with the domain as the page title, and then (from 2017) showed empty page titles and load errors, indicating a complete loss of content and functionality. The final niche before the drop was parking/blank page, which does not match the niche that built the link profile.
