SEO Plugin performance

Hi There,

I am using SEO ultimate and I have seen good reports about it. It was installed when I took the site over. To be honest it is like the does not exist in google search at the moment. The some searches coming through but really nothing for the keyphrases. I have been very successful with other sites. Sites are coming up from other countries before this one. But if do a site: search in google – all indexed and looks fine.
Does anyone else use this and what is the performance like.

Sorry I cannot add link as this will come up in search and probably will before the site and I am being asked to SEO on this site but I have set all the right keyphrases in etc. It does seem to use OG as well ie

<meta name=”description” content=”
<meta property=”og:description” content=”

Do you think that is a problem?
To me something is not right…

Thanks
Rusty
