We all know that directory submission is a popular way of Search Engine optimization and the website can be more flourished through it. Directory submissions can be done in both ways; first is the manual directory submission, which actually takes a little bit of time, but the SEO experts rely on it, more, and value it. Another one is the automatic directory submission, which takes a few bucks of the webmaster, and software is bought through it. In addition, the next procedure becomes the complete submission of the website into thousands of web directories within minutes.
There is lot of positive and negative affects of both the procedures and the webmaster uses them according to their needs and interests. Comparing Manual Directory submission with the automated one then we can say it has more authority and lends more reliability in the search engines. Most search engines normally trust the authenticity of websites that allow manual submissions and avoid on automated submissions. In this process of manual submission, get links from high profile authority directories. Most manual submissions directories have high Page Rankings and power in the search engines.

Whereas, the automatic submission directories are faster and cheaper compared to manual directory submissions. The user can easily blast his/ her website to masses of directories within minutes at cheaper rates. In this automated submission sometimes, the website may be categorized wrongly because of the bulk submission process through the software, thus getting the website rejected can increase in masses. Moreover, if it happens with more directories then the website can be penalized, sandboxed or cannot be indexed assuming it as a spam.
