Google Webmaster Tools is being plagued by a bug since July 2011, wherein it is not possible to find missing data in the "Download all sources of errors on this site" report.
Michael Martinez came up with a new Google Webmaster Help thread, where he presented a summary of all the complaints on the download.
While elaborating the problem, Martinez said that while looking at Crawl Errors/Not Found for *ANY* Website, he found these three options at the bottom-
- Download this table
- Download all errors on this site
- Download all sources of errors on this site.
Martinez said that on selecting the third option he downloaded a CSV file that included an EMPTY COLUMN labeled "Linked From".
He provided several links which shows this issue being discussed by many other people, and also highlighted that Google was not being responsive. This at last generated a response from Google, with its Webmaster Trends Analyst Jonathan Simon coming up with the following reply-
First of all thanks for the extra detail you've provided. This is an issue that we're aware of and we're working on restoring the "Download all sources of errors on this site" functionality so that the .csv file it produces includes all the available "Linked From" sources as it did previously.”
Let's hope that Google will be able to rectify the problem soon.
