Google Webmaster Tools: BOGUS 404 ERRORS!

I have been getting hundreds of bogus 404 not found errors in my google webmaster dashboard. I have NO idea what to do. Does anyone know:

1. where these references are coming from?
2. how to get rid of them?
3. how to prevent them?
4. what problems they may cause?

some examples:

mydomain.com/alabama.php
mydomain.com/arkansas.php
mydomain.com/alltell.com
mydomain.com/home.do
mydomain.com/dobson.com
mydomain.com/ci/content/url/226337.html
mydomain.com/db/ARCHIVE/WORLD_CUPS/WC2007/
mydomain.com/columns/content/story/genre.html?genre=114
mydomain.com/mydomain.com/Board/Board.asp?BoardID=1
mydomain.com/Boards.asp?Assort=1

It may be a coincidence, but one of my pages that has slowly been climbing in google rank suddenly dropped way down again after these errors started compiling.

Any help would be greatly appreciated

 

Well, I guess they aren't bogus 404's if the pages don't exist.....!

Is this just an example of referer spam or something more malicious?

 

I had one of these in my list. That tool is the most difficult thing to understand. One week, you'll get 7 URLs listed there, the next week, 0. The week after that, 1.

 

I would report this to Google..

 

Interesting.... I assumed this was something that other people experience as well, but I guess not? I will definitely report it to google asap.

 

This is something strange ... Better email to google.

 

Yeah, because google are going to do something about it!!!

 

i think i too noticed this, maybe that happens on shared hosting or something?

 

I'm on a dedicated server. It's so ridiculous. God forbid your site is being updated or goes down for an hour, Googlebot never seems to miss being there at that exact moment...then you'll get 200+ links listed as "not found" in google webmaster for a week or two

 

Here is the answers:
1- Google indexed those pages because the is links pointing to them
2- Go to the webmaster tools and use the url removal request tool
3- Use robots.txt file on your server to allow google bot to index specific pages
4- Double content - deindexing - banning.

Hope it's helpful.

 

I did a search for my problem and found someone else who had the EXACT same problem with the EXACT same bogus URLs (mysite.com/bogusphrase/bogusphrase.bogusextension). After reading that I have a hard time believing that someone is indeed linking to these ridiculous URL strings. I have come to the conclusion that it is either:

A. Googlebot being nuts
B. Some kind of spam with malicious intent

I emailed google about it a few weeks ago and of course I have not heard back from them. Any other ideas?

 

Anyone ever find an answer for this thread???

 

A lot of times people copy and paste some text into their website without knowing that they are also copying hyperlinks with the text... With some site CSS you cannot tell the difference between text and links... I would almost be willing to bet that your site is linking to those sites (obviously on accident)... I would scan your source code very carefully.
