Since a relaunch of our website we noticed a vast drop in visits almost overnight. My concern is that we used white text (CSS) on a white background with a dark graphic (background CSS). This has now been fixed and the visits have increased slightly although no where near back to where they were.
Would Google have penalised us for this? and now that we have fixed this should we now use the re-inclusion in web master tools?
I am just checking to see if anyone knows how to tell if a site has been excluded and whether Google penalises you for re-submitting the site if the problem has not been fixed (assuming that it was the white on white).
