火车头采集伪原创插件PHP版实现

luoye 2022年03月07日编程设计 277 0

很多码农都有自己的个人博客，平时谢谢笔记什么的，今天我不是谈如何做博客，而是谈如何做搜索引擎优化，结合自己多年的PHP经验来实现网站自动优化。

做一个原始网站或伪原创不仅仅是整合文本。SEO优化的原始文章与添加或删除内容无关。我喜欢用火车头来实现内容爬取，然后自己写一个伪原创插件，有兴趣大家可以自己实践下。

准备撰写文章时，请务必在撰写之前考虑本文的标题和布局。本文的标题可能基于哪个标题，并且由优化程序撰写的文章也考虑添加““锚文本”或“软链接”，因为在写文章之前，这些是要注意的事情。

伪原创或原始文章必须引起用户的注意，而不是假冒作品来欺骗搜索蜘蛛。因此，高质量的文章应具有清晰的结构，清晰的主题选择，清晰的布局并根据主题撰写文章。还可以为优化人员提供时间，并为网站带来良好的优化结果。

下面是火车头伪原创插件PHP代码：
