I have noticed that there’s a slight delay Bing News indexing since last week. Sometimes, it’s a 2-day delay, sometimes a 3-day delay. I don’t know what’s the main cause of this delay, because other sites that are indexed long ago in Bing News are not experiencing this delay. Only the sites that are recently added in the Bing News index.
I searched about this problem and I found nothing. It seems that there’s only less than 0.001% of the total world’s population are experiencing this problem. I only found one post at SEOroundtable.com about Bing News, but the information that I’ve read there is not enough to satisfy my query.
Maybe because only a few people care about Bing news right now that’s why the information about its indexing, algorithm and behavior is pretty scarce.
