Yahoo has upgraded Site Explorer with some much desired features.
My favorite is the ability to authenticate a site using a metatag, rather than requiring the upload of a text file. This was an issue for me because a client has an e-commerce platform that is totally database driven and really doesn't have a root directory to speak of. Worse, although it allows file uploads, for security reasons it only allows certain files - like images. Stupidly, txt isn't in that list. Even if it was, the upload area isn't root. So we were screwed.
Now (just like with Google) I can just go in and edit a metatag. Nice. And about time, frankly.
Some other features:
- More detailed errors
- Delete URL's
- Site Explorer Badge
- More than 25 Sitemaps
- Better labels for TSV files
- Secure (https/ssl) site support
- Change authentication speed (ie wait one day)
