Automatic directory submission

Why submit to directories?
Spend a little time researching SEO on the internet and you will soon realise that directory submission is a great way to gain incoming links to your website and increase link popularity. Changes to Google’s algorithms earlier this year meant that reciprocal links no longer bear as much weight/importance as they used to. This means that gaining one way inbound links is now the emphasis when increasing link popularity. Submitting a website to directories to be included in the listings is a great way to achieve one way inbound links.
Automatic submission:
The SE’s use inbounds links as a major part of their algorithms as it is a way to determine the importance of a website. Google’s Page Rank formula is based on the authority of websites, the idea being that the more inbound links a website has the more authority it holds.
However the SE’s do not like efforts made by website owners to artificially increase the link popularity of a website. This is why automatic submission or software generated submissions should not be considered. Submitting your website to thousands of directories in a short amount of time will actually have a detrimental effect on your websites position in the SERP’s (search engine ranking pages).
When embarking on a link building campaign the following must be kept in consideration:

• The process must be done manually.
  
• Do not dramatically increase the number of inbound links in a short period of time.
  
• Remember to use keywords in the anchor text (link title).
