我有一个不到10页的小型网站。

title标签包含站点名称,如下所示:

2018-09-02 16:11:24+0800 [BaseRedisProtocol,client] <twisted.internet.tcp.Connector instance at 0x9951e2c> will retry in 2 seconds

        txredisapi.ConnectionError: Not connected

我正在使用以下代码将页面标题动态地附加到标题标签:

<title><?php echo SITE_NAME; ?></title>

此动态生成的页面标题是否对搜索引擎可见? 标题和站点名称一起显示在SERPS中吗?

尽管大型企业SE可以并且经常提供JS渲染,但是它们不能渲染所有内容,也不会触发任何用户操作。因此,这在很大程度上取决于如何以及何时调用此代码段。另外,至少Google并不总是将源中的标题用作搜索结果中的图块。 但是,强烈建议您不要这样做。恕我直言,这种方法效率极低且无法扩展。另外,大多数爬虫会以这种方式错过您的标题。
