the crawl request of my company site: https://www.dhgate.com/ has dropped nearly over 95%, from daily 6463599 requests to 476493 requests at 12:00am on 9th, Oct (GMT+8). This dramatic dropping trend not only showed in our GSC crawl stats report but also our company's own log report. We have no idea what’s going on.
We want to know whether there is an update of google about crawlling, or is this the issue of our own site? If something is wrong with our site, in what aspects would you recommend us to check, analyze and accordingly optimize?
