Top 5 current black-hat SEO techniques

The underword of black hat SEO in usually in a state of flux. Current blackhat SEO focuses on getting lots of back-links. Here's my top 5 list of popular blackhat SEO technqiues.

1. Duplicate content.
This is my favorite black-hat SEO technique. I say "favorite" not because it works, but because it's the one I've seen most of as of late. With this technique, people create 1,000 domains, and then post the same content on each domain. I'm not sure what they're thinking. This technique is probably the biggest waste of time and money that I've see for quite some time.. I did SEO on a site that fell victim to this game. They purchased a turnkey website. The website looked really cool. The only problem is that it was the exact replica of an existing website. I did a search and turned up 400 versions of the same website. Needless to say any SEO that we did for this site had exactly no effect whatsoever. It took us two months to figure out what why nothing was working. So trust me on this, it's impossible to get a website ranked in Google if your website is a carbon copy of someone else's.

2. Spamming people with link swapping requests.
I still chuckle when I receive automated link requests. These were very popular in the past, and still are to some extent. This technique involves using software to spam people and ask them to swap links. As far as techniques go, this is more annoying to regular people than anything else. It probably won't get you black-listed by Google. You may however, get in trouble for spamming people. Also, this technique doesn't really work.

This software makes it easy for two companies to bury reciprocal links to each others websites. I have to make a confession - I used this software 4 years ago. It was when I was young an naive. It worked back then. I was able to create backlinks to over 100 sites in about 10 minutes. Of course, all the back-links were worthless. Even back then, this was really an exercise in futility.  If you do it now, it will also get you blacklisted from Google.

4. Invisible Text.
Don't use invisible text - ever. People who still advocate the use of invisible text deserve a good poke in the eye. There are more recent variations of the invisible text trick – notably one using CSS to hide text – which might still work. I know of one example where someone got a number 1 ranking on Google using invisible text. I’d share it with you, only the site is no longer listed at Google. Nuff said.

5. Cloaking, sneaky Javascript redirects, and doorway pages - These techniques round out the top 5.

Cloaking refers to the practice of presenting different content or URLs to users and search engines. Serving up different results based on user agent may cause your site to be perceived as deceptive and removed from the Google index.
Some examples of cloaking include:
  Serving a page of HTML text to search engines, while showing a page of images or Flash to users.
  Serving different content to search engines than to users.
I don't know why you would want to do this. But, if you do, Google will find you, and delete you from your index.

Javascript Redirects

When Googlebot indexes a page containing JavaScript, it will index that page but it cannot follow or index any links hidden in the JavaScript itself. As such, it's possible to direct users to one page, and Google to another. This lets you show one thing to actual visitor, and another thing to Google. This is a great idea, until Google does a wget of your page while pretending to be Microsoft Internet Explorer. Can you say "caught"?

Doorway pages

Doorway pages are typically large sets of poor-quality pages where each page is optimized for a specific keyword or phrase. In many cases, doorway pages are written to rank for a particular phrase and then funnel users to a single destination. Whether deployed across many domains or established within one domain, doorway pages tend to frustrate users, and are in violation of Google's webmaster guidelines. Google's aim is to give users the most valuable and relevant search results. Therefore, they get upset when people manipulate search engines and deceive users by directing them to sites other than the ones they selected.
