Being a webmaster, I am sure you are aware of the fact that the more number of links you get from other websites, the more amount of visitors you get, the higher your website appears in Google (and other search engines) and higher goes your PR (Page Rank).
Submitting your website to directories is an excellent way to achieve all of this. This directory submission not only provides you with excellent one-way links but also provides you some traffic. Within a day or two, your website is popular amongst the search engine spiders and there you go, increased ranking in SERPs (Search Engine Result Pages). With this you get targeted purely organic traffic to your website.
Now, submitting to hundreds of directories can be boring, and tedious too, especially when you have many websites. Getting someone to do your directory submission solves your problems. Directory submission services are fairly cheap and are worth every penny you spend on them. The standard rates are 15$ for 100 websites, and any company which can offer you good quality reports at any price lower than 15$ is a steal. It would be better if you take slow directory submission service, because this way the number of backlinks to your site appears natural. Make sure that the directories you are submitting to are ones, which have “do follow” tags (i.e. no “no follow” tags).
While hiring someone, you should always ensure that your site would be submitted to the category which is most relevant to your website. You can get people who offer directory submission services in almost every Webmaster forum like Digitalpoint, Warrior forums, etc. If any service provider can guarantee a high acceptance rate [above 75%] in the submitted directories, the better it is for you.
Be sure not to overdo directory submissions, as it will result in a sudden increase in the backlinks of your site, which would appear suspicious.
May the Google be with you!
