Both, I'm using these method for a year and in comparison. I can say that Blackhat brings me traffic that more that i expected.

Do you thinks guys Blackhat is better that Organic SEO?

Organic SEO, of course, is better than Blackhat. Unethical SEO tactics will get you banned on search engines.

black hat is easily detected.i love grey hat..where i use methods which are not black hat yet...

When Google discovers your black hat tactics on your site, your site may not appear on SERPS which is a very high price to pay. Just remember that!

Black Hat SEO is always considered to be unethical way of Optimizing a website.It may attract high traffic,no doubt about that, but in the later days to come you may see a negative impact on the site rankings in different search engines result pages. Whereas if you take efforts in an ethical way,long terms benefits can be seen.Though, it takes sometime for the results to be seen using White Hat SEO techniques, but you can be rest assured about the results.

Blackhat methods are good for instant traffic but can harm your websites credibility. You may get banned by major search engines like google and yahoo. Using organic SEO can ensure you that your site will last longer on internet and will receive benefits from search engines for long term.

I have a very simple way of explaining SEO. Basically the internet is made up of three groups, white hats, grey hats, and black hats. I didn't make these terms up they actually come from western tv shows\movies. White hat SEO takes more time to learn than black hat SEO but black hat SEO is taboo. When I first started out trying Search Optimization I accidentaly made some black hat moves. I'm thankful that some folks here at Daniweb pointed that out to me or my Website would more than likely have been banned from search engines.

White hat SEO isn't that hard, I have actually written a lot about it on one particular thread along with other DaniWeb users. http://www.daniweb.com/forums/thread163359.html
that thread helped save a guy $1000 that he didn't have to pay a company to white hat optimize his site. I strongly encourage you to read that thread and several others on the SEO forum.

Thanks for sharing that thread. Black Hat SEO may provide good short term results but in the long run, it is like making a deal with an unethical agent. Think of it as steroids. It may give you fast results but it is not good at all.

I totally agree!! Lets take something that has nothing to do with programming, oh let's use sports for example. Okay let's say you just hit a home run and the baseball hit the hubble telescope (yeah that's impossible, this is just an example). Well, later a few reporters get suspicious on how you could hit a ball so hard and make it go so far and they find out you are using steriods that say in fine print "Made on Mars, may have unwanted side effects for human beings". Well, I'm sure you've already figure out that you would be kicked out of the league and probably would be questioned about your communication with Martians. Now back to reality, Black Hat SEO is the same way you get great results and you make your way up the search charts until a google official notices your using black hat techniques and "strike three your out!" of googles search engine and most likely all other search engines.

I hope someone got a kick out of my space humor.

Well Tiger, I did smile with your martian remark. Imagine a martian on steroids. Well I think that is what Black Hat SEO. It will make it obvious to the powers that it was not legit.
