Most internet sites receive about 75% of visitors from search engines like Google, Yahoo or MSN. Google is the worldwide market leader in the search engine market. Because of this fact it is very important for every webmaster in the world to archive good rankings in Google’s search engine result pages (SERPs).
The most efficient way to archive good ranking in search engine result pages is to collect a lot of inbound links from authority sites for a specific niche. For a lot of webmasters selling links was quite a profitable way to make some quick cash. The monthly price of a link is mainly based on the Page Rank of the site selling the link. The Page Rank is assigned by Google and is visible in the Google Toolbar. Recently Google penalized sites that selling too much outgoing links. Many of those sites lost some of their Page Rank. This is the reason why selling links is much more difficult nowadays.
Selling links and excessive link exchanges are against Google’s webmaster guidelines. Though, Google suggests to collect many quality inbound links in order to achieve better rankings in the search engine result pages. But this process of getting inbound links has to be natural. It’s not recommended, for example, to have 100,000 inbound links within 1 day. Getting 100 links per day over 1000 days (3 years) are look more natural to search engines.
Even well known web directories can lost their Page Rank. A lot of directories were penalized because not following Google’s webmaster guidelines, so most of them are useless for link campaigns.
You have to write articles and submit them to a directory. It’s very important that you write unique content; because Google also reduced the Page Rank for many duplicate content pages. It’s more likely to get a good inbound link from an article directory if you submit unique content.
You can automate the process of creating unique articles and distributing it to thousands of article directories, over certain period of time by using Unique Article Wizard.
