I was just experiences then reading about recent issues with Yahoo’s Site Explorer not reporting the correct amount of backlinks (as if that exists lol). I still use it quite a bit, especially with a quick SEO Quake fix, so it’s good to know that the Yahoo team is working with the Bing team to bring it all back to working order. The good folks at Webmaster World definitely have a thread going, and Vanessa Fox already blogged about it so I won’t go into too much detail.
Basically, you can bet that Bing is working on integrating the data into their Webmaster center, and hopefully it gets a sprucing up. We all know Google’s tool is garbage for the most part…no surprise there though really. For now I always recommend Link Diagnosis to pull Yahoo’s data since the API version is still working normal. You can of course try out SEOmoz’s Open Site Explorer or try out Majestic SEO. Here’s what the Yahoo team had to say officially;
We are working with the Microsoft team to ensure that webmasters can continue to use Yahoo! Site Explorer to view inlinks (a.k.a backlinks) to a given webpage or a website and to further be able to export them as CSV if desired.
Please note that this functionality will be available only through the Site Explorer UI and not through the Webservices API.
