What do you mean wrong? Blogspot is SEO friendly I guess It will be indexed faster compared to other sites
I'm not sure about automatic but I don't think it's possible unless you ping the posts and build some links.... Try building links, sitemap, ping the new posts and use social networking sites to get indexed quickly.
yes they will index your site automaticly because blogger is a part from google but it will take some time
The answer is yes. The blogger (blogpsot) do have 2 advantage 1. Automatic get indexed by google 2. Easy to get approved by adsense
I've had my blog indexed in a couple of days with backlinks from just my sig here at DP and some of the blog networking sites (BlogCatalog, MyBlogLog, Technorati). I waited until I had 4-5 posts before doing that though. I also claimed my blog in Google Webmaster Tools, which certainly didn't hurt. Also, be sure in your Settings you have "Let search engines find your blog?" set to "Yes"
Well in my case study back in July 2007, I made a blog did around 50 post on it, make no backlinks or any inbound links and till today July 3, 2008. it is still not indexed!!!! on the contrary, I made a single page blog, did sprinkle a few backlinks here and there and within 8 hours it got indexed and the following day it's already ranking on the main keywords I am targeting it for. SO there's your proof
blogspot... is better than any other blog hosting since it will be indexed fast than any other blog hosting sites.
