Some of the tactics include link farms, keyword stuffing and hidden text:

- A link farm: is a group of web sites that all link to each other without any regard to quality or relevance. People create websites and the sites are then cross-linked to other sites in the same network, and would also include one-way links to the primary site with varying anchor text. Once the visitor has arrived to the website, the owner of the website will often use some kind of cloaking or redirect to show the visitor a sales page of the products, that is the really goal of the Black Hat SEO technique.

- Doorway or Gateway Pages: These are very simple and poorly designed web pages that act as doorways or gateways to another but just as poorly designed web page. Doorway pages often contain a link you’re asked to click if you wish to obtain more information about a given topic. Clicking on the link, however, will lead you to a useless page, but as far as black hat SEO marketers are concerned, they’ve done their job because they’ve got you to visit and search engine spiders will count that in their favor.

- Keyword Stuffing: is one of the most popular Black Hat methods. In this method, the website is ’stuffed’ full of any given keyword; content and readability of the text is severely compromised. The text is often pushed to the bottom of the page and put in a small font, the hope is that the search engine will see the keyword is used many times and rank it well.

- Hidden Text: is a similar method where a keyword is written repeatedly in the same color as the background; this usually gets the site reported by its competitors quickly and results in the site being blacklisted.

- Page Hijacking: these are websites containing very similar content to popular and original websites. They hijack the content of other websites as a deceptive means of gaining traffic.

- Results (rankings and traffic) start slowly. You will normally see results within 3-4 months.

- The fact that Search Engines algorithms change, what causes lack of guarantees and certainty, confuses many online marketers. Many online marketers consider it as one of the SEO’s worst down points. They assume that a business that relies heavily on search engine traffic can suffer major losses if the search engines stop sending visitors and it is better to liberate yourself from dependence on search engine traffic and instead make the technique of having links from other websites (with its various shapes) your main sources of traffic.

- There are some old search engine optimization techniques that were deemed to be spamming the search engines and can actually get your website blacklisted.

Another important rule to consider while using SEO is that never try to repeat keywords, focusing on keywords does not mean repeating them over and over at all.

Remember that Google considers websites with repetitive keywords as “spam”

Keyword density has increasingly become less important to search engine robots as it can be viewed as spam if over used. Try to be very light with the density (no more than 12%)

Finally, here is the ultimate fact; you can really make a lot of money through search engine optimization, you can help the other websites in their promotional activities. If you help them by placing their links or their banner ads, you can earn a lot by charging them for this favor.
