I just read a blog (i'm sorry i forgot the link) but anyway in that blog it stated that when you never optimized to bing you will miss atleast 10 to 20% of traffic. Is that true? On the other hand I also read some forum thread saying that "You dont have to concentrate with Bing because once you've indexed in google all other search engine sites will follow". So which is the true behind these? Hope to get a feedback. Thanks in advance.
