Google, Bing and all of the other search engines out there use bots to crawl the web to build their index. They’re programmed to crawl the web, review what they find and change or update as they find new pages. Recently, there’s been some concern with activity by the Microsoft spider bot.
Web masters who are diligent about visitor stats on their sites have noticed some errant bot activity from Microsofts end of the web. The activity that’s been found strange? The Microsoft web crawler, appears to be coming into websites cloaked. It’s something that’s happened before, that they were able to rectify, but this time calls to correct the problem have gone un-answered. A point which has raised the tiny hairs on webmasters necks, the bot isn’t just bouncing on a site once or twice over the course of a day or two. Some are reporting activity in the 10+ times per day range.
The silence about the activity, the cloaked visits and the multiple pings per day are all very erroneous activity from any spider bot. Let alone a bot owned and controlled by such a large internet property. Some webmasters, are even speculating.. has it perhaps been hacked?
