4XX (Client Error)

How much will 5 of these errors hurt my search engine ranking for the site itself (ie: the domain) if these 5 pages have this error.

not sure if this is any help to anyone but I have almost the same issue but it's a 500 error and the description says:

Traceback (most recent call last): File "build/bdist.linux-x86_64/egg/downpour/init.py", line 391, in _error failure.raiseException() File "/usr/local/lib/python2.7/site-packages/twisted/python/failure.py", line 370, in raiseException raise self.type, self.value, self.tb Error: 500 Internal Server Error

Talking to my hosting provider they said when the seomoz bot crawled my site it put my cpu usage over 25% causing the errors...  We will see if this happens on Sunday.

One of my crawls has just completed and I see that I have 5 404 : Error messages that display the same error as quoted.  I feel that I am being a little pedantic as 5 does seem petty in comparison to the numbers quoted by the other members, I would just like to know if there is something that I can do to eliminate these.  Please can you advise if this is something only derived by the moz crawl itself or if it may have something to do with an external cause that I can influence?

I greatly appreciate your time.

Thank you!

We do know about the 406 errors, and we uploaded a fix for that on Tuesday. Your next crawl should not show these errors again.

I am experiencing exactly the same thing as alsvik-- I went from 0 406 errors to 681 in one week, having changed nothing on my site.  Like him, it is PDFs and .jpgs that are generating this error, and I get EXACTLY the same error message.

Clearly, SEOmoz has changed a python script such that their bot no longer accepts these MIME types.  Please correct this ASAP.

I just got spammed with 406 errors. Seomoz suddenly found 390 of these on my site (all png, jpg and pdf).

I have changed nothing on my site and GWT shows none of these. So i'm thinking that the Seomoz-crawler maybe doing something wrong ...

It all boils down to trust. I trust GWT (it may be slow though).

it is on a pdf with a link on it.  The error message says:

It's hard to quantify the impact of the 404 pages not knowing the relative size of your site.

Overall, the 404s aren't good for your SEO.  You should work towards fixing the pages that are giving the error or 301 redirecting the bad urls.
