完成以后，我们最关心的是网站是否被搜索引擎收录，网站关键词排名是否靠前以及网站的文章被收录了多少。
今天我们介绍一种方法，可以在文章中显示此文章是否被百度收录。如果该篇文章已经被百度搜索收录，则显示”百度已收录”;如果该篇文章没有被百度收录，则显示”百度未收录”，点击链接会进入百度 url 提交页面，帮助该篇文章尽快被百度收录。
1. 切换到主题目录，打开 functions.php 文件，加入以下代码：
';
} else {
echo '';
}
}
?>
Crayon-line Crayon-striped-line" id="Crayon-5c891d282ef99599683481-34">Crayon-h">@H_403_1@Crayon-sy">}@H_403_1@Crayon-h"> @H_403_1@Crayon-st">else@H_403_1@Crayon-h"> @H_403_1@Crayon-sy">{@H_403_1@
Crayon-line" id="Crayon-5c891d282ef99599683481-35">Crayon-h">@H_403_1@Crayon-k ">echo@H_403_1@Crayon-h"> @H_403_1@Crayon-s">''@H_403_1@Crayon-sy">;@H_403_1@
2. 在文章页面 single.PHP 合适的位置上添加如下代码：
Crayon-5c891d282efa8299812164" class="Crayon-Syntax Crayon-theme-classic Crayon-font-monaco Crayon-os-pc print-yes notranslate" data-settings=" minimize scroll-mouSEOver" style=" margin-top: 12px; margin-bottom: 12px; font-size: 12px !important; line-height: 15px !important;">
