luckily, I don't take anyones advice on anything lol
where do I start? errr...
doorway pages, cloaking scripts, hidden text, 100 lines of rubbish keywords at the bottom of each page (still see this occasionally), bunch of 1x1 pix img tricks, FFA farms, link farms, seen it all pretty much!
The SEO industry is a f'kin joke nowadays.
I've posted my Yak fur coat example too many times, so I'll leave it at that.
