Why is the website indexed by google?

Recently, I found that GOOGLE indexing on my website is not normal and is decreasing every day. I searched for it and found that there were no such cases as online collection, keyword cheating, and group sending. My website was originally edited by professional editors, the external link is also made up at, and its server is very stable. Check IIS logs. Everything is normal. GOOGLE crawls hundreds of pages every day, all 1.1, and there is no problem.

 

Modify the website error page 404.htm to add it to the top of the 404.php page.

<? Php
Header ("HTTP/1.0 404 Not Found ");
?>

In this way, the 404 page returns 404 instead of the 200 normal page!

The GOOGLE website administrator center is indeed very practical. It can identify various problems on your website and solve them one by one. Although GOOGLE does not bring much traffic, it is always better than none! You must be careful when optimizing your website. You may make a big mistake if you make an inconspicuous mistake!

My website Baidu is updated every day, but GOOGLE is not updated for several weeks. There must be something wrong, so I have to go to the Google website administrator Center to see it, because there is a website diagnosis tool. After verifying the website, GOOGLEi prompts that the 404 page of your website returns normal 200, and finally finds the cause! It turns out that the 404 page error outputs 200 normal code. Please change it.
