I’ve been searching the forum and found any info about this question. From what can tell, Google penalizes organic rankings for duplicate content. Our main site is being designed for SEO (we use index/follow tags). But we have several AdWords minisites that we use that have duplicate content of the main site (landing pages are modified a bit according to AdWords keywords). For these types of AdWords minsites, I’m wondering what would be the best index/follow tag to use? I don’t want the duplicate content on the minisites to compete/pentalize our main website, but I also want the AdWords spiders to make full use of them (to keep my AdWords Landing page quality score up, etc). Is it suggested to use noindex/follow on these minisites so that the AdWords will index them, but the Search Engines won’t try to index them and see them as duplicate content? Or is it safe to use noindex/nofollow so that the engines will see that we are not trying to create duplicate sites, but will this tag still be safe to use with AdWords. Any suggestions would be greatly appreciated.
