One way links and search engine rankings have a great cause and effect relationship. Think of it as a business referral scheme. The business with the more referrals is most popular and hence, search engines place them higher. The reason behind it, as many place it, is that the more links you have, higher are the chances of a visitor coming to your site over these links!

Again, the search engines send out spiders to the links they find in the directory pages. This will take the search engine spiders to your site and will make your web site pages added to the search engines indexes automatically.

In those initial days, the easiest way to get several incoming links is directory submission. In fact, if you are attentive to the details, you can get some good quality one way links for free from niche directories. These links will definitely help you to make some page rank along with visitors. But you must think that all directories may not be good for your web site. You must skeptically select the best directories from millions of online directories.

However, there are some primary criterions for proper directory submission to get links from good quality and SEO friendly directories. When we say SEO friendly links, we mean that the incoming links should not have attributes and should not be java script links. The incoming links with noindex or nofollow attributes and java script links will not pass PR juice to your website.

1. Most of the great quality directories do not take sites that are under construction..

2. Good directories do not let orphan pages or gateway pages..

3. Some directories will not let deep linking

4. Good directory only allow you to submit your page under the most relevant category or the webmasters may reject your link.

5. Good directory will reject website with duplicate content issues.

6.Good directories do not allow URLs that redirect to another web site.

Not all free directories are bad. If you don't submit it won't hurt you, but you could miss a prospective chance. On the other hand, if directories really present as results for the terms you are optimizing for, submitting to the directories is the same as submitting to the "niche directories".

So if you're considering submitting but time holds you back, you can outsource the directory submission job to a group of people or company somewhere else in the earth where labor is smaller.

If you do a quick search in Google, you can find a lot of directory submission service providers who do an excellent, efficient job. All you have to do pay a small amount and the job will usually be finished in a number of days.
