Getting Listed in Google Search

Day before yesterday I was damn thrilled since my blog was getting listed in google search. I searched using various combinations and some or the other posts on my blog would be shown as the result of the google search. However, today mysteriously google has decided not to list my blog. I tried using the same words for which my blog was listed only day before yesterday but invain. I somehow need to understand how the search engine behaves.

I had used the first technique of the below mentioned 3, around a few weeks back to get listed on google searches.

1. Submit Direct To Google
The first method is to submit your web site via Google's free submit your site form. Just submit your home page and Google's crawler, Googlebot, will crawl the rest.
However, Google does not add all submitted URLs to their index, and there is no guarantee as to when, or if, your site will be indexed.
2. Get Linked From A Site That Google Crawls
The second method is to get a site that Google already crawls to link to your site. So when Google recrawls the web site, it will find the link to your site and crawl and index it as well.
This is Google's preferred method of finding sites to index.
To get another site to link to yours, simply look for a site that links to your competitors and ask them to link to yours. You may have to offer a link back to their site in exchange.

3. Submit Your Site To The Yahoo! Directory & The Open Directory Project Index
The third method is to submit your web site to the Yahoo! Directory and/or Open Directory Project index, which is owned by Netscape.
As far as I know, this is the only guaranteed method of getting into the Google index.
Google has agreements with Yahoo! and Netscape to include the sites indexed in their directories in the Google index. So submit your site to either, or both (recommended), of these directories.
For more information, visit Yahoo!'s How to Suggest Your Site page and the Open Directory Project's How to add a site to the Open Directory page.
Once your site is included in either of these directories, it will appear in the Google index in about 4 to 8 weeks.
