There are so many criterions that search engines follow to determine a site's rank for certain key or search words. One of these includes links to the site. The page rank of a site is directly related to the number of links it has. The more links you have pointed to your site, with some variation of the key phrase you want to rank high for, the better ranking in the search engines you will receive.
Relationship between directory submissions and search engine rankings
One way links and search engine rankings have a great cause and effect relationship. Think of it as a business referral system. The business with the more referrals is most popular and hence, search engines rank them higher. The reason behind it, as many put it, is that the more links you have, the higher are the chances of a visitor coming to your site through these links!
Again, the search engines send out spiders to the links they find in the directory pages. This will bring the search engine spiders to your site and will get your site pages added to the search engines indexes automatically.
In future, the new search engines will also follow the same procedure. Hence, you won't have to register to them, rather they will find you themselves!
You can also improve your sales!
Again, many people actually do surf these directories to look for the things they want. So they will also act as a medium to bring in your prospective customer to your site.
Thus, directory submission has three major benefits, which makes it the indispensable tool of online marketing.
1. Higher Position In The Search Engine Results
2. Web Site Indexed
3. Click Through Traffic
So that is something one should focus on if they are interested in increasing the rankings and traffic of their site. Many sites who offer submission service, claim to submit your link in more than 75000 directories (mind you, few even claim the figure to be around 7,00,000!). But one should remember that submitting a link and getting it listed in the directory is not the same thing. It is like an auction, you don't win merely by bidding.
