I have created a blog http://howspeeduppc.blogspot.com 10 days ago. I have done submissions for it... & also ping it in blog directories..But it's not caching... let me knw how can it cached by google.
submit your blog in google webmaster tool also submit your blog ion digg, reddit this type of high popular and high PR website your website can crawl in one day
Submitting in Google webmasters is also not that useful these days. I have submitted my website in webmasters but it is too slow. My website was previously indexed but the link information and caching power even after submitting to that tool is the same. Its not of much help i would say!!
I've had the same problem with one of my blogs and am about to start a link building campaign to different pages.
i'd say do pingomatic then add it in webmaster tools and blogger will submit an automatic sitemap for you. then you have to wait and cross your fingers. also make sure you add a description to your blog. blooger is really good at providing what google wants to see from a structure standpoint so you are on the right track. you can also search your blog url in google to see if it exists, then your site is being reported jsut ranking low.
