You cannot afford to go left! Directory submission must be done right in order to rip the benefit form this crucial link building method. There are thousands and thousands of link directories out there where you can submit your site or blog to. But out of that many thousands of directories, only a fraction actually offers the real backlink and some PR benefit.

There was time when directory submission would work like magic when it comes to link building. It still does work to some extent but not as much as it used to be before. Extreme competition pretty much exhausted all the traditional link building methods and to stay competitive in the game, one needs to do more than what others doing; both in terms of quality and quantity. Some might say it's the quality of backlinks that matter and not the quantity, I would say they both matter. If I have only few good quality links and my competition has more good quality links than me along with a lot of OK quality links, I'm the one who is behind in the game. So even with good quality backlinks, one needs as many of them as possible till the competition is beaten. . 
 
First most important step in directory submission would be to find as many niche blogs as possible and submit the site to them. Niche directories are a new trend and by now, there are niche specific directories in almost all major niches. Submitting the site to those directories will give you relevant backlinks which will be more valued for ranking purpose.
 
Once you are done submitting to as many niche directories as you can, next step would be trying to put together a list of all high ranking directories with as many backlinks as possible. More backlinks a directory has, more frequent Googlebot visits the directory and better chance you have for quick indexing of your link. High ranking directories also pass higher value link juice.
 
If you are reading this far and still wondering what is the world is being talked on this article or what do the terms directory submission and link building mean, the you should know that a site needs to be properly optimized with as many backlinks as possible being pointed to the site to rank high in search engines. Higher the site ranks, better flow of traffic there will be meaning more viewers/readers and more revenue for money making webmasters.
 
One last thing I would like to touch up on is deeplink directory submissions. Aside from niche directory and general directories, there are deeplink directories that accept deeplink submissions with some only accepting deeplink submissions. It would be beneficial to spend some time finding as many directories as possible and put together a large deeplink directory list. Once the list is made, you can start submitting your inner pages and/or social media pages to these directories.

So if you want to get good benefit out of directory submissions, spend a lot of time on the web searching for as many directories as possible, sort them out by priority, and keep submitting. Take a slow and steady approach and don't go overboard by submitting to 4,000 directories in a month and nothing on the second month. It is more advisable that you submit to 1,000 or 2,000 directories over the course of 2-3 months. This way the link building campaign would look lot more natural and organic in the eyes of search engines.
