I continue to have certain keywords that SEO Panel shows no results for. If I check the log for the keyword it shows success and if I then search using the search query string SEO panel uses it indeed has no results. If I use the same keywords in a search on Google I get results.
So the search query SEO Panel is using has a bug in it. I have noticed this in a various sites now. One site with 15 keywords never showed any results but all were in the top 15 if I searched the same exact keywords in a Google search.
