## 説明

**– This plugin has been adopted! Please review the description below. –**

A 404 page is what a user sees when they try to reach a non-existent page on your
site (because they’ve clicked on a broken link, the page has been deleted or they’ve
mistyped a URL).

While the standard 404 page can vary depending on your web host, it doesn’t usually
provide the user with much useful information and users may just surf away from 
your site. Therefore, Google recommend creating a custom 404 page that provides 
the user with more information about your site and its content.

The Google 404 widget is a quick and easy way to embed a search box on your custom
404 page and provide users with useful information designed to help them find the
information they need. Where it can, the Google widget will also suggest other ways
for the user to find the information they need, thus increasing the likelihood that
they’ll continue to explore your site.

For best results, you should set up a [Google webmaster account](http://www.google.com/webmasters/)
and submit an XML sitemap of your blog to ensure the Google 404 widget works effectively.

#### Features

Currently the plugin outputs the Google 404 widget in US English by default, or 
tries to use the current WordPress language.
 You can use the `google_404_language`
filter to specify a different language code.

Also looking to add the possibility to [change the appearance](https://support.google.com/webmasters/answer/100044)
of the widget.

#### Please note

The Google 404 widget plugin is NOT a WordPress widget.
 It is simply the term Google
use to describe their enhanced 404 page script.

#### Adoption Story

This plugin was originally developed by [Ben Huson](https://profiles.wordpress.org/husobj/)
and was adopted in September 2014 thanks to the [adopt-me](https://wordpress.org/plugins/tags/adopt-me)
tag.

#### Coming Soon!

The ability to customize the CSS from an options page within the WordPress Admin
area, attempt to dynamically inject the Google search box without needing to modify
your template files, and more!

## インストール

You should first set up a [Google webmaster account](http://www.google.com/webmasters/)
and submit an XML sitemap of your site to ensure the Google 404 widget works effectively.

 1. Download the archive file and uncompress it.
 2. Put the “google-404” folder in “wp-content/plugins”
 3. Enable in WordPress by visiting the “Plugins” menu and activating it.
 4. Add the `google404()` function call to your 404.php template.
 5. if ( function_exists( ‘google404’ ) ) { google404(); }

You could also add this code to your theme’s index.php, single.php, image.php, archive.
php and search.php below the HTML that is displayed if no posts are present (where
you insert this may vary from theme to theme).

You may also use the `google_404_styles` and `google_404_language` filters for manually
overriding the CSS values or language used by the Google 404 widget.

### 󠀁[Recommended As A Replacement to WordPress 404](https://wordpress.org/support/topic/recommended-as-a-replacement-to-wordpress-404/)󠁿

 [](https://profiles.wordpress.org/gegan249/) 2016年9月3日

I’m using Virtue and after creating a child theme, moved 404.php to my child theme(
so it wouldn’t be overwritten at a core update.) In place of Wordpresses `<?php 
get_search_form(); ?>’ I replaced the plugin’s Google 404 search bar and it worked
perfectly. It’s a better user experience.
