Drhooba,

Based on what you wrote it doesn't appear that you were doing anything that would have gotten you de-indexed. Have you looked at any other error reporting in webmaster tools? For instance is there malware detected on your site? If so this can cause a drop in traffic because visitors will be warned in SERP's that the site is infected. Are you blocked in SERP's? Try typing in site:www.yourdomain.com into a search bar and see what comes up. If you don't see any results for your website there is a good chance you were removed from the index.

Perhaps you could find some tips here,

Hope that helps,

Hey I forgot to mention, you can skip adding a keyword meta tag. Google does not use this meta tag as a ranking factor. In fact, Bing supposedly uses it to identify spam sites.
