Dead business websites in Turkey 2026: reachability of 685,343 company web addresses by province and sector

This is the single largest failure class, larger than every HTTP error combined.</li> <li>The rest: 58,025 returned a 4xx status, 32,729 timed out, 7,924 returned 5xx, 3,236 refused the connection, 2,693 redirected without resolving, 911 were malformed URLs.</li> <li>Sector spread is wide. Car dealers (33.5% reachable), real-estate agents (34.8%) and real-estate firms (39.6%) are the worst; ATMs (95.8%), banks and credit unions (95.4%) and mobile phone stores (82.4%) the best.

A regulated balance sheet appears to predict a working website better than being an internet-facing consumer business does.</li> <li>Province spread is narrower than the sector spread but real: Tokat (54.8% reachable), Elâzığ (55.2%) and Van (55.4%) sit at the bottom, well under the 60.4% national average.</li> </ul> <h4>How to read the failure classes</h4> <p><code>dns_missing</code> is the strongest signal: the hostname has no DNS record, so the domain has lapsed. <code>http_4xx</code> mixes genuinely missing pages (404) with bot blocking (403 accounts for 34,778 of them), so it is a weaker indicator of abandonment.

A site counted as reachable answered with a 2xx during the crawl; no judgement is made about its content.</p> <p>Method, province and sector tables and the interactive report: <a href="pinlyx.com/research/dead-business-websites-turkey">English</a> / <a href="pinlyx.com/tr/arastirma/olu-isletme-web-siteleri">Türkçe</a>.</p> <p>Published by Pinlyx (formerly CRM Solid), <a href="pinlyx.com">https://pinlyx.com</a>.
