Make sure you place the meta information Google gives you in the index.html of the skin you are using. Place it BEFORE the meta title in that file. Example below.
{config_load file=$skin_color_scheme}
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" lang="en" xml:lang="en">
<head>
<meta name="verify-v1" content="xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx=" />
<title>{$meta_title|htmlspecialchars}</title>
<meta name="description" content="{$meta_description|htmlspecialchars}"/>
<meta name="keywords" content="{$meta_keywords|htmlspecialchars}"/>
