This week I had 50 plus sites that got deindexed. I have another group of 200 sites that I'm worried will suffer a similar fate, in that they all have adsense on them. ( Everything about those sites is white hat, but I don't trust Google at all). I plan on selling the domains on Sedo. Figure the easiest thing to do is change the DNS on all those sites to go to SEDO parking, as removing adsense on each site is too time consuming. However, I'm concerned that I may get deindexed by the mere fact that they are on a SEDO adsense page. What do you think is the best parking strategy? Should I leave the nameserver info blank?
