since when a black hat SEO technique considered good to use? IMO, if you didn't get notice using that, then its good, and if they notice it, of course its bad.
as far as i know, more believe that this a black seo thing,, but in some manner its not. its depend on how you used it, but. for assurance and site safety dont do it.
There's a difference beween IP Delivery, and Cloaking. IP Delivery- One IP sees something that only it needs to see. A specific version that gives nothing misleading, and has tiny differences. Note: Google does this. It redirects you based on the country of your IP. Cloaking - Hiding keywords and the like. Makes you show up in SE results where you would not otherwise.
Cloaking is out there for quite some time. Just a few webmasters can use it right & gain profit. It is not efficient only for a short period of time. Takes a lot of effort to cloak the right way & fly under the SE radars. Content is a major factor in cloaking. Automatic generated content will get u poor results in long terms. SE getting smarter but cloaking community is one step beyond. No magic formulas for black hatters through, the good ones worked really hard before the happy ending. xmcp123 is Fantomas your tool? Too expensive i think
No, but Fantomaster's tool is truly exceptional. I wrote my own though, so of course I believe it's better . I'll put some hints out there. Keep in mind, this is for a site that link spams and cloaks, so it doesn't WANT a lot of traffic(from message boards, blogs, etc). It's meant to have only SE traffic. I wrote a blog about it Cloaking Techniques. Consider it a gift.
This is a textbook straw man argument. You're the only person to mention low bandwidth visitors, mobile phones, or "search engine friendly URLs." The definition you posted is very broad, and even then that last example is more like exposing a different calling convention to the inside vs outside world ... for all visitors. Nobody ( except you ) has suggested the idea that serving a different CSS file for IE versus FireFox will get you banned. That silly, easily refuted argument that nobody made doesn't change the fact that serving different content to GoogleBot versus Internet Explorer will get most sites banned, and just isn't worth the webmasters' time. It's been said that GoogleBot sets its UA to match IE or FF occasionally, to compare the results against what it sees when it announces itself.
