changed to wordpress and lost ranking

Hi,

i was ranked for my main keywords between page 2 and page 3 with my little one page site.

3 days ago i changed from standart html template to wordpress cms and added 7 pages of content and completely lost all the rankings.

is that normal ???

I could be wrong, but it happens sometimes. Just because your site was a change of poorly indexed. Wait a bit. Ideally, it should not be

I think its because of the site redesign plus the 7 pages of new content is a lot for Google to process. If it was me, I would remove the new content for right now and make sure that all of navigation is all the same. Whenever you change your site Google is going to have to re-index you so always anticipate it.
