Google Webmaster Tools Downloading More Than 1000 Crawl Errors
After switching from our old eCommerce host we noticed the we had over 16,000 website crawl errors indicated on Google Webmaster Tools almost all of them related to the way our old eCommerce host formed unique tracking urls.
We wanted to eliminate these with 301 redirects. Unfortunately, Google Webmaster Tools only allows downloading 1,000 crawl errors at a time. We found this CrawlError resource at GitHub and using this we downloaded all the crawl errors, formatted the .csv file for our current website and uploaded all the 301 redirect information.
