I made a mistake with one of my website and a whole bunch of data got picked up by Google before I caught it. I need to fix this relatively fast by asking Google to drop the index pages. The URL would be something like: domain.com/index.html?action=Abcd Does anyone know if I can submit: domain.com/index.html?action=* as a single request through webmaster tools? If not, what are my other alternatives?
Submit a new sitemap and 301 the old thing to the new page or the main domain. It's dirty but it does the job (did it on a few sites already).
