Our website - ycnonline.com - used to be at the top of the table when it came to searches, particularly for just the key word ‘ycn’ (no surprises), yet only a week or two since the new site went live (using CI, obv), any trace of ycnonline.com has completely vanished.
Has anyone experienced this before, and could anyone have a shot at what the reason could be?
Google had indexed a while bunch of now invalid links, but I thought the majority of these were dealt with using htaccess redirects, so I wouldn’t have thought that’d be the issue.
Secondly, while my doctype is XHTML 1.0 Transitional, there are a great many non-XHTML compliant tags (simply haven’t had time to tweak them): would this cause any issues with Google?
