Good luck !!! and also I can add some types for Bing Optimization blog.e-works.am/en/bing-search-engine-optimization-seo-tips/
I knew about all these but reading your post I decided to check all the info they offer. The strange things is that I get almost no traffic from bing.
Recently I got more search from bing search engines. Some how I like bing more than google. I have one adsense site that convert well from bing organic search. I'm using wordpress platform and unique content, playing with low competition keywords and keep the density, also the keywords is in the domain name make me 100++ from adsense alone from one site (per month0. That site is just 2 months old.
seo guru actually said that you must first concentrate your seo first in bing and yahoo for google will definitely index all unlike msn and yahoo. thanks for the link
also I think it'll be useful for You to use bing webmaster tools: http://www.bing.com/webmaster It works fine, not as google webmaster, but we shouldn't forget that it is growing and developing. The webmaster tool's information helps to optimize Your site correctly and get info about it. It also cashes links from approved directories I think it is the time to concentrate about bing too. Good luck
The Bing URL submitter is work but only for a single page index. I've been using this (formerly MSN submitter) for a long time, but around 70% of the websites you submit will be indexed by Bing. Normally they take around 24 to 72 hours to crawl your web. If more than that period, your site may not be index any more and so you have to resubmit. Hope help. Anyway thanks for the link.
