404 Error on Spider Emulators

[beeneeb]

Hi Zack,

Looking at your robots.txt file, you have several errors.  I would replace your current robots.txt file with the following:

User-Agent: *
Disallow:

Sitemap: http://www.uncommongoods.com/sitemap.xml

(not sure why the message truncated your sitemap file, but you get the picture)

Hi Zack,

Actually, when I use this http header tool and that I input http://www.uncommongoods.com/ I see that the header returned is in fact a 500 Internal Server Error.

The HTTP Header is returned by the server even before the browser can kow that their is javascript on that page so it has nothing to do with javascript.

You'll have to look at the server side as an Internal Server Error and the HTTP Header are returned by the server in opposite to the javascript that is executed client send.

Hi Zack,

Quick followup : Your website will always return 500 to HTTP/1.0 queries.  With HTTP/1.1, homepage returns 404 and subpages returns 200.

I saw the website was running on a Resin server rather than a Apache server, then, you might want to look into your Resin server's configuration.

Hi Beeneeb,

Thank you for your insight. I think this makes sense as I see there is some redundancy in robots.txt as it is now. I'm curious however, why do you think that changing robots.txt will resolve the 404 error?

Hi Zack,

To be honest with you, it was just a guess.  I used a robots.txt syntax checker and saw several issues.  You can check out that same tool here & run your current robots.txt file through it:

I hope that gets you pushed in the right direction.  I'm very new to SEO, but I've worked in the technical support world forever.  So, my suggestion is only worth what you paid for it.

Hi Beneeb,

That tool is awesome! It definitely helps, thanks! I'm going to show that report to my IT guys today. I think your guess is a very good one. Hopefully I can persuade them to make the changes and we'll see if it resolves the error.

Best Regards,

Hi Zack,

The 404 error has nothing to do with the robots.txt file, it has to do with your server configuration as I said in my answers bellow.

About the robots.txt file, I would remove the Disallow: line if you don't need to block anything.

Best regards,

Hi Guillaume,

Your comments about Javascript on the client side make complete sense to me now and I will examine our Resin config w/ my IT team. Thanks for explaining. Also, as per Beneeb's advice above, I'm going to try making some changes to robots.txt.

From a bigger picture perspective though, do you think this 404 Error is even that big of a deal? Are we likely to be penalized for this in terms of Page Rank, Domain Authority, etc..??

Thanks for your help!

Hi Zack,

Yes, having the home page return a 404 error is a HUGE problem.  It actually tells the engines that the page doesn't exist so they will stop crawling it and eventualy drop it from their index even if it returns content.

You should solve this problem ASAP!

Hey Zack,

It seems your website is now returning a 200 so you apparently managed to fix the problem.

Was the problem coming from the server configuration as I suggested?

Best regards,
