Client error 404

[mato]

I have got a lot (100+) of 404´s. I got more the last time, so I rearranged the whole site. I even changed it from .php to .html. I have went to the web hotel to delete all of the .php files from the main server. Still, I got after yesterdays crawl 404´s on my (deleted) .php sites.

There is also other links that has an error, but aren't there. Maybe those pages were there before the sites remodelling, but I don't think so because .html sites is also affected.

How can this be happening?

I am using SEOMoz crawler and I am using Dreamwaever. it was Dreamwaever that didn´t do its job. It was supposed to change in all of the documents but of some reason jumped over, not all, but some files.

In other words. All ok with me.

Sorry.

Hi Tobias - how are you checking 404s, are you using SEOMoz crawl diagnostics?

If so, export the CSV! Many people dont do this yet there is a plethora of info there.

1. Open the csv, and sort by the "4xx" column so that all of the 'TRUE' cell values are at the top.
2. Delete / Hide / Move all columns except: URL, 4xx, TIME CRAWLED and REFERRER

Now you can see which URLs are 404,'ing, how the crawl found them (where the link is that sent the crawler there) and what time it crawled (in case youve fixed it since.

Its easy and its thorough.
