Given helpful suggestions from discussion group, Google has improved feedback for sitemaps in Webmaster Tools. Now, minor problems in a sitemap will be reported as "warnings," and will appear instead of, or in addition to, more serious "errors." (Previously all problems were listed as errors.) Warnings allow us to provide feedback on portions of your sitemap that may be confusing or inaccurate, while saving the real "error" alarm for problems that make your sitemap completely unreadable. Google hope the additional information makes it even easier to share your sitemaps with Google.

The new set of warnings includes many problems that Google had previously classified as errors, including the "incorrect namespace" and "invalid date" examples shown in the screenshot above. Google also crawl a sample of the URLs listed in your sitemap and report warnings if the Googlebot runs into any trouble with them. These warnings might suggest a widespread problem with your site that warrants further investigation, such as a stale sitemap or a misconfigured robots.txt file.

Please let Google know how you like this new feedback. Tell them what you think via the comments: http://googlewebmastercentral.blogspot.com/2007/07/new-warnings-feedback.ht
ml, or in the discussion group (http://groups.google.com/group/Google_Webmaster_Help). Google also appreciate suggestions for additional warnings that you would find useful.

A faster way to find what you're looking for. Introducing Search Suggest on Yahoo.com

It works like this: When you do a search on Yahoo!, you'll automatically be given suggestions based on what you have typed - as you're typing. So, not only does this limit the number of words you need to type into a query, it may also present similar queries to shorten your searching time and get to what you're looking for quicker. Search Suggest isn't new, just new to Yahoo.com. Yahoo launched this feature in its Yahoo! Toolbar in Firefox a while back and you can get it directly from the Firefox 2 search box when you select Yahoo! as your search engine.

The nice thing about the suggestions is that they're not obtrusive, so if you already know what you're searching for, you can overlook the suggestions without them getting in your way. But, when you experience those brain dead moments like we all do, it's the type of feature that just might get things moving again. If you don't like change, you can turn it off altogether by simply selecting "disable" in the bottom right corner of the drop down menu. And, if you're having regrets, you can reinstall it by selecting "more" above the search box.

Try it out and let Yahoo! know what you think here: http://www.ysearchblog.com/archives/000469.html
