I was questioned today by a developer who was watching a particular IP address scan his site. The IP was and is registered to Microsoft Corp. located at One Microsoft Way, Redmond, Washington 98052. This visitor was not sending the normal header information associated with a crawler to the web server such as an http robot name or identifying info or even a browser name.
Microsoft search engine. But then within just hours of the visitors exit from the site the new same search at Microsoft's new search engine shows all of the urls in question being fully indexed within its results. My Theory On This Mysterious Microsoft Crawler The old msn required a fee to be crawled by its spider. But a few months back MSN dropped the fee and said they were going to begin crawling the entire web and doing it without charge. However, that's no easy task. So I believe MSN is using the results from Google and possibly even Yahoo to get all of the pages they've indexed on sites that have a relatively low page count in the current msn search engine. First off, that's the fastest way to get the relevant pages from a web site. Sure they could just go to the site directly and start crawling but in doing so they're going to get tons of duplicate urls and urls that seem different but point to the same content. Crawling Google's results will eliminate the bandwidth to some extent but will not completely take care of the duplicate content issue their spider will encounter. Secondly, crawling Google's results can act as a qualitative measure for their new search engine. By creating a baseline number of pages per site when the new Microsoft Search is launched and running a comparison on a regular interval for the next 6 months, they'll be able to determine internally if their engine is finding and indexing the same links and as many links as Google. Call it competitive analysis or whatever you want. So Microsoft's Screen Scraping? Obviously my conclusion should be taken as a grain of salt but it's a definite possibility. Microsoft very well could be screen scraping Google (or maybe even using their API, LOL) and crawling the urls it finds. It makes sense from a business case but I wonder if there are any legal issues there. I doubt it. It's like putting garbage out to the curb. Once it's out there it's fair game but I bet Google's lawyers would have more to say than that on the case. Has anyone out there seen similar behavior on their own sites? Please MarketingShift.com.
