Major changes to your website can impact your serps. Keyword density, long tailed keywords, etc. that got you the good results will change. In time, hopefully you will regain your positions in the serps and then some. I don't know the specifics about your site (large, small, dynamic fed pages, etc.), so I give you these general tips... Make sure you have a sitemap and point to it with your robots.txt file. Any pages that were dropped, 301 them to the new. That will help to carry page rank over while delisting the old page in the search engines. On any major overhaul, I always suggest bumping up your link building efforts. Since you may have new pages, likely with new URL's, the added backlinks will help to stabalize your site in the serps. Of course it is always best to retain the same URL structure if possible, but I don't know if you did that. Good luck. I'm sure others will point out more tips as well.
HI Carl, with my New Zealand based search engine, your changing your sites data and structure would be found the next time our webspider did a refresh crawl of your website and from what I understand most other search engines are the same, so I would doubt if you need to do anything because the next visit of a search engines webspider would update your sites details automatically. We crawl every website in our index every seven days to keep our data base fresh and accurate. I hope this helps you out my friend. Dave Andrews from the LinkNZ search engine
