Mayday Mayday !!! My SEO plane just crashed and burned…

[SAB]

This is the story

I was on page 2 (Google) for my keyword At the time I had 2 websites ( 1 of them RAW html with "on page seo" the whole 9 yards) and then off that website you could click to go to the online shop hosted on a ecommerce site.


My back links at the time:

V7n
Aviva
hub.roi.com.au
www.internationalwebdirectory.com
linkcentre.com

Recently because I had a high exit rate on my index page I uploaded oscommerce on to my site (site has over 800 pages now) to entice user to purchase or view products more.

Then I submitted to 3 more directories

botw.org
www.2yi.net
www.alivedirectory.com

Now I’m ranked (on Google) page 3 at the bottom.

I think everyone will say I lost my rank because of my site now being oscommerce because there is nothing SEO about it but I would like some feed back as to what I could have done wrong here.

PS: I must Note Google after 3 weeks still is yet to see that I am listed on botw and alive directories.

Thanks
