I had an application on a domain while it was in development, for around one year. During that time content grew steadily but the application was buggy and google found plenty of errors.
Four months ago I moved the complete application to a new domain but I did not use google webmaster tools to change the address. Recently I have started to do well for my main keyword and decided that I would 'move' the old domain to the new, in order to give the site increased age.
Today I find myself dropped from position 18 to 34 for my keyword which is rather disappointing to say the least.
Not having changed anything else, can anyone envisage my being penalised for this change of address. Should I cancel the request or might it fix itself?
Advice is appreciated.
