Does anyone here know many keywords/ campaigns / adgroups are allowed in Adwords, Yahoo & MSN? The reason why I am asking is because I plan on creating a lot of campaigns and adgroups in Adwords and then importing or copying them over to my MSN Adcenter and Yahoo accounts. I know Google allows something like 50,000 keywords, 200 campaigns and lord knows how many adgroups, but does Yahoo and MSN have high limits like this or are they lower? Also what would be the best way to import from Google to MSN and Yahoo? Thanks
