Ranking on Google.com not listed in Google.co.in

Hi,

I am running a small business and am trying to get my website to rank on certain keywords. But I find that while I have some presence on Google.com search I do not list on Google.co.in ( India Search )

I used to rank on India seach engine earlier : about a month back

This is essential for me as the keywords are of the format :
keyword cityname

My current ranking for keywords are :
Keyword Google.com Google.In KW1 68,144,328,329 NONE KW2 69,210,346,347 NONE
Ranking checked on : www(dot)seoserp(dot)com/web_tools/google_top_1000_serps_checker(dot)asp

I know it is not a high rank but I am not sure if I should even move forward with off site seo if my site does not list on the search engine I want it to.
Getting a Google.com listing for my keyword is virtually useless for me. Google.co.in is what matters as most Indian users are automatically redirected to Google.co.in when they type Google.com

I am running the website on wordpress,taking pains to ensure good onsite seo, did some directory submissions, use SENuke to do a few blasts.


My theories :
1) I thought may be the SENUKE blast was affecting the ranking of my website as I was doing it once or twice a month. But I guess if it were to effect my ranking I should have been kicked out of google.com first
2) The recent change I did to the website about 2 weeks back was adding geo tags to my website. To mark the location of my city. This appears on all pages of the website.
3) Google dance ? Why would Google dance only on India search
4) My website does list on India search for my domain name.
I have the top 5 spots on India search for my domain name. So the site is not blacklisted from the Google India search.
5) I am runnning Adwords Campaign on these Keywords.I thought while I gain ranking it makes sense to tap visitors. And the response to Adwords made me feel that I should really go for the top ranking. But I am not sure if this should in any ways be responsible.
6) The content is original. There is no duplicate content on my website.

How can country listing be so different from Google.com Listing.

I am really at my wits end. I hope some Expert warriors can guide me regarding this issue.
