However, starting November 2020, Googlebot may crawl sites that may benefit from it over HTTP\/2 if it&#8217;s supported by the site. This may save computing resources (for example, CPU, RAM) for the site and Googlebot, but otherwise it doesn&#8217;t affect indexing or ranking of your site.<\/p>\n<p>To opt out from crawling over HTTP\/2, instruct the server that&#8217;s hosting your site to respond with a 421 HTTP status code when Googlebot attempts to crawl your site over HTTP\/2. If that&#8217;s not feasible, you can send a message to the Googlebot team (however this solution is temporary).<\/p>\n<\/blockquote>\n<blockquote>\n<p>\u307b\u3068\u3093\u3069\u306e\u5834\u5408\u3001Googlebot \u306f HTTP\/1.1 \u7d4c\u7531\u3067\u30af\u30ed\u30fc\u30eb\u3057\u307e\u3059\u3002\u3057\u304b\u3057\u306a\u304c\u3089\u30012020 \u5e74 11 \u6708\u304b\u3089\u306f\u3001\u30b5\u30a4\u30c8\u304c HTTP\/2 \u3092\u30b5\u30dd\u30fc\u30c8\u3057\u3066\u304a\u308a\u3001\u5229\u70b9\u304c\u3042\u308b\u304b\u3082\u3057\u308c\u306a\u3044\u5834\u5408\u306f\u3001Googlebot \u306f HTTP\/2 \u3067\u30af\u30ed\u30fc\u30eb\u3059\u308b\u3053\u3068\u304c\u3042\u308a\u307e\u3059\u3002\u30b5\u30a4\u30c8\u3068 Googlebot \u306e\u30b3\u30f3\u30d4\u30e5\u30fc\u30c6\u30a3\u30f3\u30b0\u30ea\u30bd\u30fc\u30b9\uff08\u305f\u3068\u3048\u3070\u3001CPU \u3084 RAM\uff09\u3092 HTTP\/2 \u30af\u30ed\u30fc\u30eb\u306f\u7bc0\u7d04\u3067\u304d\u308b\u304b\u3082\u3057\u308c\u307e\u305b\u3093\u3002\u3057\u304b\u3057\u3001\u305d\u308c\u4ee5\u5916\u306e\u70b9\u3067\u306f\u3001HTTP\/2 \u30af\u30ed\u30fc\u30eb\u306f\u30a4\u30f3\u30c7\u30c3\u30af\u30b9\u3084\u30e9\u30f3\u30ad\u30f3\u30b0\u306b\u306f\u5f71\u97ff\u3057\u307e\u305b\u3093\u3002<\/p>\n<p>HTTP\/2 \u3067\u306e\u30af\u30ed\u30fc\u30eb\u304b\u3089\u30aa\u30d7\u30c8\u30a2\u30a6\u30c8\u3059\u308b\u306b\u306f\u3001HTTP\/2 \u3067\u30af\u30ed\u30fc\u30eb\u3057\u3088\u3046\u3068Googlebot \u304c\u8a66\u307f\u305f\u969b\u306b\u3001421 \u306e HTTP \u30b9\u30c6\u30fc\u30bf\u30b9\u30b3\u30fc\u30c9\u3092\u8fd4\u3059\u3088\u3046\u306b\u3001\u30b5\u30a4\u30c8\u3092\u904b\u7528\u3057\u3066\u3044\u308b\u30b5\u30fc\u30d0\u30fc\u306b\u6307\u793a\u3057\u307e\u3059\u3002<br \/>\u3082\u3057\u3053\u308c\u304c\u5b9f\u884c\u3067\u304d\u306a\u3044\u5834\u5408\u306f\u3001<a href=\"https:\/\/www.google.com\/webmasters\/tools\/googlebot-report\">Googlebot \u30c1\u30fc\u30e0\u306b\u5831\u544a<\/a>\u3067\u304d\u307e\u3059\uff08\u305f\u3060\u3057\u3053\u306e\u89e3\u6c7a\u6cd5\u306f\u4e00\u6642\u7684\u3067\u3059\uff09\u3002<\/p>\n<\/blockquote>\n<p class=\"p30-t\">HTTP\/2 \u3067\u306e\u30af\u30ed\u30fc\u30eb\u306f\u3001\u30da\u30fc\u30b8\u6570\u304c\u591a\u304f\u3001\u914d\u4fe1\u3059\u308b\u30ea\u30bd\u30fc\u30b9\u306e\u6570\u3082\u591a\u3044\u5927\u898f\u6a21\u30b5\u30a4\u30c8\u304b\u3089\u59cb\u307e\u308b\u3068\u4e88\u60f3\u3057\u3066\u3044\u307e\u3057\u305f\u3002<br \/>\u305d\u3046\u3057\u305f\u30b5\u30a4\u30c8\u306b\u6069\u6075\u304c\u3042\u308b\u3060\u308d\u3046\u3068\u671f\u5f85\u3067\u304d\u308b\u304b\u3089\u3067\u3059\u3002<\/p>\n<p>\u306a\u306e\u3067\u3001\u50d5\u306e\u30d6\u30ed\u30b0\u7528\u306e\u3088\u3046\u306a\u898f\u6a21\u304c\u5c0f\u3055\u304f\u9759\u7684\u306a\u30b5\u30a4\u30c8\u306b\u306f\u3001\u5c11\u306a\u304f\u3068\u3082\u521d\u3081\u306e\u3046\u3061\u306f HTTP\/2 \u3067\u306f\u30af\u30ed\u30fc\u30eb\u3057\u306a\u3044\u3060\u308d\u3046\u3068\u8003\u3048\u3066\u3044\u307e\u3057\u305f\u3002<br \/>\u3068\u3053\u308d\u304c\u3001\u3044\u3056\u84cb\u3092\u958b\u3051\u3066\u307f\u308b\u3068 HTTP\/2 \u30af\u30ed\u30fc\u30eb\u3092\u767a\u898b\u3067\u304d\u305f\u306e\u3067\u3001\u6b63\u76f4\u9a5a\u3044\u3066\u3044\u307e\u3059\uff08Googlebot \u3092\u507d\u88c5\u3057\u305f\u30af\u30ed\u30fc\u30e9\u3068\u3044\u3046\u53ef\u80fd\u6027\u3082\u30bc\u30ed\u3067\u306f\u306a\u3044\u3067\u3059\u304c\uff09\u3002<br \/>\u3082\u3063\u3068\u3082\u3001\u3069\u308c\u3060\u3051\u30e1\u30ea\u30c3\u30c8\u304c\u3042\u308b\u306e\u304b\u306f\u4e0d\u78ba\u304b\u3067\u3059\u3002<br \/>\u305d\u308c\u3067\u3082\u3001HTTP\/2 \u30af\u30ed\u30fc\u30eb\u306b\u60aa\u3044\u3053\u3068\u306f\u307e\u3063\u305f\u304f\u3042\u308a\u307e\u305b\u3093\u3002<\/p>\n<p>\u7ba1\u7406\u30b5\u30a4\u30c8\u306e\u30b5\u30fc\u30d0\u30fc\u30ed\u30b0\u3092\u3042\u306a\u305f\u3082\u78ba\u8a8d\u3057\u3066\u304f\u3060\u3055\u3044\u3002<br \/>HTTP\/2 \u30af\u30ed\u30fc\u30eb\u306e\u75d5\u8de1\u3092\u898b\u3064\u3051\u3089\u308c\u308b\u304b\u3082\u3057\u308c\u307e\u305b\u3093\u3002<\/p>\n<p class=\"p40-b\">\u5927\u898f\u6a21\u30b5\u30a4\u30c8\u3067\u306f\u3001\u30b3\u30f3\u30d4\u30e5\u30fc\u30c6\u30a3\u30f3\u30b0\u30ea\u30bd\u30fc\u30b9\u306e\u6d88\u8cbb\u3092\u6291\u3048\u3089\u308c\u305f\u308a\u30af\u30ed\u30fc\u30eb\u52b9\u7387\u304c\u3088\u304f\u306a\u3063\u3066\u3044\u305f\u308a\u3059\u308c\u3070\u3001Googlebot \u306e HTTP\/2 \u30af\u30ed\u30fc\u30eb\u306f\u304b\u306a\u308a\u5b09\u3057\u3044\u6539\u826f\u306b\u306a\u308b\u3067\u306f\u306a\u3044\u3067\u3057\u3087\u3046\u304b\u3002<\/p>\n<h2>\u3053\u306e\u8a18\u4e8b\u306e\u95a2\u9023\u52d5\u753b<\/h2>\n<div itemprop=\"video\" itemscope itemtype=\"https:\/\/schema.org\/VideoObject\">\n<iframe loading=\"lazy\" importance=\"low\" width=\"800\" height=\"450\" src=\"https:\/\/www.youtube.com\/embed\/jFfnpLEW4eg\" title=\"YouTube video player\" frameborder=\"0\" allow=\"accelerometer;
