Microsoft thinks Bing is pretty clever. And Yahoo certainly likes Bing enough to throw its own search engine overboard in favor of Microsoft's newly redesigned one. Yet Bing has a long way to go to become a meaningful challenge to Google.
Bing has earned praise for the smart way it presents certain search results. For instance it breaks down some results by category, giving you an easy way to quickly hone a search for "swine flu" with information on "symptoms" or "causes." It will also helpfully show previous searches you've made in a column to the left of the results.
Yahoo's CEO, Carol Bartz, said last week that such improvements in Bing reflect the way people actually use search engines "instead of just thinking like just the standard blue link."
Even so, Microsoft's share of U.S. Web searches went up only slightly after Bing launched last month -- hitting 8.4 percent in June, after Microsoft recorded 8 percent in May, according to comScore Inc. Microsoft's previous search engine, Live Search, also showed a similar increase when it came out, as Microsoft heavily promoted it.
Never miss a local story.
And Bing's small gain came at the expense of Yahoo, not Google, which maintained its 65 percent share.
I think I can see why. Not only is using Google such an ingrained habit that we talk of "googling" something, but also its technology is better in some key ways. Testing Bing, I found it to be less comprehensive than Google and, surprisingly, Yahoo Search. It simply returns fewer results for a lot of search terms.
With common terms like "cars," all the search engines return oodles of results. Yahoo reports 2.56 billion pages with that term. It doesn't matter so much how many pages they report, as long as they give relevant results, and all do.
Then I tried to hunt for something purposely obscure, like background on the country manor that my sister is interested in buying. Google gave me 46 links, Yahoo 15. Bing supplied just six. The most relevant one turned out to be in Google and Yahoo only. And that turned out to be the case in several other searches that were on the fringes of what you'd expect the Internet to know.
Years ago, search engines competed by citing their "index size" -- basically, how many pages they had collected in their database. Google played this game too. But as Google grew to dominate the scene by presenting better results, Web users lost interest in the statistics. Google doesn't make a big point of them anymore either, but it did say last year that it had more than 1 trillion Web pages catalogued.
Looking at results from Bing, it may be time to care about search index size again. That's especially the case because in other respects, the top three engines are so similar as to be nearly indistinguishable. Nos. 2 and 3 have basically copied Google.
All of them present neat and clean search pages and advertising that's placed through an auction process (advertisers bid for the right to show their ads alongside certain search terms, and pay the search engines when a user clicks on an ad). Search for a common term like "diapers," and they yield nearly identical results.
They do have other little things that set them apart. Google injects a helpful little map when it finds a location among the top results. Yahoo has (or soon we might say "had") a Search Pad application that lets you annotate your results, a useful aid in an extended research or shopping project.
Bing presents a preview of each search result if you hover your mouse cursor over it. And it helps you dig further faster with its links of categories to the left of the main results.
Microsoft has said that it put special attention in Bing to presenting authoritative results in a few areas, like health information, but the effort seems a little superficial. That's why when you search for "swine flu," the Mayo Clinic's presumably more reliable page will appear above Wikipedia's. But if you search for "toddler fever," the results look indistinguishable from those on the other two engines.
Bing is young. It's possible Microsoft can make its index catch up to Yahoo's and even Google's, but doing so won't happen overnight. More likely, it will take years.
That's plenty of time for Yahoo users to discover that Bing -- for all of its niceties in presentation -- lacks depth. If they do, they'll know where to go, and Google would end up being the winner on this deal.
