Indexing errors divide into two stages, and knowing which stage failed tells you who has to fix it. Download errors<\/strong> mean the robot never got the document. Processing errors<\/strong> mean it got it and could not use it.<\/p>\n

Download errors and their limits<\/h2>\n
    \n
  • Text size limit exceeded<\/strong> \u2014 the document is over 10 MB<\/strong>.<\/li>\n
  • Maximum URL length exceeded<\/strong> \u2014 over 1,024 bytes<\/strong> in the domain name or in the host page address.<\/li>\n
  • Maximum HTTP header length exceeded<\/strong> \u2014 Yandex names the usual cause outright: too many cookies<\/strong>. A tag manager or consent platform stacking cookies can make pages unfetchable while every browser copes fine.<\/li>\n
  • Invalid message length<\/strong> \u2014 check content-length<\/code>; the declared header size must not exceed the actual document size.<\/li>\n
  • Invalid data amount transferred<\/strong> \u2014 transfer ended early or continued past the declared length.<\/li>\n
  • Wrong encoding<\/strong> \u2014 Transfer-Encoding<\/code> set incorrectly or unknown.<\/li>\n
  • Plus the connectivity family: connection failure, connection not established, DNS error, invalid HTTP status code, invalid HTTP header, unsupported document format, invalid document address, and blocked in robots.txt<\/code>.<\/li>\n<\/ul>\n

    Processing errors<\/h2>\n
      \n
    • noindex<\/code> meta tag present<\/strong> \u2014 deliberate, if you meant it.<\/li>\n
    • Wrong encoding<\/strong> \u2014 characters that do not match the declared encoding.<\/li>\n
    • Document recognised as a server log<\/strong> \u2014 an unusual one, and Yandex’s advice is telling: if it is a real page for visitors, change it so it does not resemble a log. Pages that are mostly timestamped rows can fall into this.<\/li>\n
    • Invalid document format<\/strong> \u2014 the file does not match its declared type across HTML, PDF, DOC, RTF, SWF, XLS and PPT.<\/li>\n
    • Encoding not recognised<\/strong> \u2014 possibly no text, or text in mixed encodings.<\/li>\n
    • Language not supported<\/strong> \u2014 the language was not recognised or is not supported.<\/li>\n
    • Document contains no text<\/strong> \u2014 the case behind a large share of “the page looks fine to me” reports.<\/li>\n<\/ul>\n

      How to use this<\/h2>\n

      Read the error, decide which stage it belongs to, and route it accordingly: download errors go to whoever runs the server or the CDN; processing errors go to whoever builds the page. Sending the wrong half to the wrong team is the most common reason these sit unresolved for months.<\/p>\n","protected":false},"excerpt":{"rendered":"
