Dealing with Not Found errors

[JohnHuynh]

Hi,

I have a problem with Google Webmaster, it reported that I have many errors 404 Not Found. 
I have detected and found the links are coming from my site, I have fixed them and submit a new sitemap to google again. Then, I wait a few days, google still report errors 404 Not found same as before.

I don't know why? Please help!

For an example about this problem:

Google webmmaster report Not found link: www.vietnamvisa...com/tips/6.html (this is link before update).
and in the tab Linked from: http://www.vietnamvisacorp.com/tips.html, but in this page did not include /tips/6.html

this is not a problem you simply have to take these links that you're finding is 404's and 301 redirect them to relevant pages on your website. What I mean is do not simply take them and put them all to the home page. Spread them around if they have no direct use. I've noticed you are using Nginx along with Apache where you might be just using Nginx in order to make the 301 redirects correctly with engine acts I'm going to need to grab a couple links for you. I will be right back.

sincerely,

Thomas

Hi John

Mark it as fixed in webmaster tools

After that, just leave it alone for a week or so. Once your site is recrawled, youll see that it's not there anymore (as long as it's really fixed)

here is the information I retrieved  regarding how your website is made website

https://builtwith.com/?http%3A%2F%2Fwww.vietnamvisacorp.com%2Ftips.html

http://www.vietnamvisacorp.com/tips.html

http://wiki.nginx.org/LikeApache-htaccess

so let's say you wanted to make it back into the original URL I have above

to fix it and Apache

Permanent URL redirect - generated by www.rapidtables.com

Redirect 301 /tips/6.html http://www.vietnamvisacorp.com/tips.html

now to fix it in Nginx

Use

http://winginx.com/htaccess

or

http://www.anilcetin.com/convert-apache-htaccess-to-nginx/

nginx configuration location /tips/6.html { rewrite ^(.*)$ http://www.vietnamvisacorp.com/tips.html redirect; }

http://winginx.com/htaccess

Hello John & Dennis,

if it is completely gone and there's no 404 you can check this by going to the Google Webmaster tools panel and instead of selecting ignore or anything like that hit fetch as a Google bot this will tell you if the link is still a real link or not. You do not have to wait a set amount of time to find out if one link is in fact okay.

I would be hard-pressed to imagine that it is worth anything meaning it has back links pointing to it however if it does you will want to use open site Explorer to check the link prior to ignoring it or marking it as fixed.

The rule I use is if it shows up as a 404 I 301 redirect it that way you never lose back links. It's a little more complicated using  Nginx but in my opinion it's worth the complication as the improved speed and ability to take incredible amount of traffic make it really worth it.

What Dennis has stated is true if the link is worthless And of course does not exist Anywhere on a webpage.

I hope this has been of help.

considering that your website has both index and archiving on and Google obviously has indexed and archived your website I would strongly suggest you eliminate this is a obstacle in the future and simply 301 redirected the correct path

http://www.vietnamvisacorp.com/tips/6.html

If using Nginx like I think you are simply implement this in your htaccess

nginx configuration location /tips/6.html { rewrite ^(.*)$ http://www.vietnamvisacorp.com/tips.html redirect; }

I used this tool to accomplish this goal http://winginx.com/htaccess you can do the exact same thing using this and it will help you if you already understand how 301 redirect for Apache

http://www.anilcetin.com/convert-apache-htaccess-to-nginx/

if you want to be certain to get the code right which I would I would use an Apache generator then put it into the Nginx generator and properly 301 redirect your 404

simply use the tool below to create the and copy and paste that redirect into one of the 2 tools I have given you above.

I have marked as fix many times, and then the errors still occur. When I check my sitemap and did not see the not found links which are listed in the tab linked from sitempap.

That is why I 301 redirect all of my 404 banks simply because Google has already indexed and archived them as I mentioned. So you need to 301 redirect the links I hope this helps sincerely, Thomas
