Ah, I remember doorways pages from when I started out in SEO way back in 2004. Back then they were invisible, but that’s another story.
Google’s latest announcement regarding doorway pages is intriguing. I hope that the aim will be to demote the bad boys in the SERPs – i.e. those that scrape and mash together bits of syndicated content in a bid to dupe Google into thinking that what lies in front of them is fresh, unique content.
