Before getting into the nuts and bolds of this article I want to make perfectly clear that I don't encourage the use of blackhat SEO alternatives. Still, what if there are some "unofficial" schemes that actually deliver results with a minimum of risk assumed.

This subject must be clarified because there are armies of internet marketers that use SEO without any results. For the most part they remain reluctant to using blackhat methods for fear of not loosing existing rankings - a commodity that's not easily found in the average SEO campaign.

1. Link exchange - this stopped being an efficient offsite optimization practice unless is backed up by one way back links. Google has no problem detecting reciprocal linking patterns. When this happens, they generally exclude them from its index.

The probability of this happening is dictated by your linking partner's value and the frequency of your link reciprocation acts. For a solid website, in a white hat environment, this practice is considered to be legitimate and is an expression of what the web community is all about - inter-connectivity.

For those sites that build links only through this method and in addition they also partner with dodgy webmaster, the improvements in raking power are always short lived. Instead of investing time and effort in tracking down reciprocal linking opportunities, focus on crafting valuable content that's easily promoted and willingly linked to.

2. Page Onload Redirects - this works pretty well when first employed but once discovered could trigger some harsh penalties; the sever one is permanent exclusion from the SE's index. These days, the major SEs have become even more competent on discovering JavaScript redirects.

If you plan on moving content whether it's an entire website or just a single page use the 301 redirect. 301 Redirects enable you to retain the PR value and transfer it new online properties. Before moving, verify that the domain is not expired and/or the page handles the exact same subject line.

3. Investing your money in links - very profitable indeed but must be carried out with unexploited back link sources and in a well camouflaged manner. Without doubt this generates one of the hottest debates among search engine marketers. And the reason is obvious - it can get you solid results.

But there's a trick. In order to work effectively for you, search engines must not discover these transactions. A sound strategy would be to place your money in quality articles that come with relevant backlinks pointing to your webpages. The best paid links acquisition are those that are 1) hard to spot or 2) difficult to duplicate by competing marketers; especially true if they're cloth in highly relevant content.

Keep a low profile on your link purchases. That way, they won't be so accessible for your competition which makes them even more beneficial both in Pagerank conservation and domain exclusivity.

4. Link building Networks - if the relevancy factor isn't carefully monitored these can trigger ranking droppings. Search engines have no difficulty detecting such networks all the more so if these have a thin portfolio of third party backlinks being pored into them.

Google tracks down link farm networks via the C block IP range. The way around this is to open multiple hosting accounts with different services and as suggested above continue to build inbound links to the various sites - segments in your linking network.

This approach could prove being a valuable reservoir of backlinks to the degree that you can supply enough content for your future, interconnected sites.

5. Hidden Text - there are other legit ways of keyword optimizing your web pages.

There are other more effective means of influencing rankings than this and it's not worth the risk. Currently, Google finds this task somehow hard to accomplish, but in competitive niches there are always marketers ready to draw attention upon your "optimized" web pages.

6. Cloaking - can be efficient but for a website to be properly indexed it requires link equity.

Namely, preparing two versions of the same content. One for the search engine spider and one for the human surfer. If done correctly this practice is hard to discover by search engines. And there are some programs to use one being Fantomaster. I don't recommend it though, because your website becomes outdated as the web continually evolves.

7. Automated Content Generation - if your intentions are clean, it can't be considered a risky SEO practice. In my opinion this practice is totally outdated since Google has already improved their ranking algorithm and duplicate content isn't capable of ranking effectively. To be more exact there are specific duplicate content filters that filter out the SE's index of web pages.

From all these questionable off-site SEO practices, I would suggest learning the art of link scouting and ultimately link brokerage. Refrain from investing into SEO services provided by specialized firms. The majority of link acquisition will go into website directories and backlinking networks. Alternatively, learn to scout linking opportunities on your own.
