One of the best alternatives is to try and outsource the job to a professional SEO company so you can save your time and money
. Even before selecting any such company it is important that you read a few reviews related to them online so you are sure that you have selected one of the best companies for completing the job effectively. The general rule when doing directory submission is to try and submit to a few directories in a single day so you can get the desired results. In case you are looking for much better results then selecting a delayed submission service is also one good option. Such manual directory submission services complete the job in different steps over a period of time to make the submission more effective. So there are chances that they might even choose to complete nearly 1000 submissions in a period of one month. They certainly might also make use of separate titles for each submission to get better results.
