Manual directory submission is the process of manually submitting a website to searchable online directories. This process is an integral part of link building for Off-page Optimization as it helps search engines find the submitted website and identify it as more important than other non directory indexed websites. Because there are thousands of page results for any given keyword, search engines evaluate these results to determine which are more valuable and accordingly give them a higher rank. Websites that are properly indexed and categorized in online directories are perceived by search engines to be more valuable and deserve a higher rank. Now, the reason Manual directory submission is the preferred submission choice verses automated software tools is that these tools are often used by spammers which is why link directories don’t accept this method of submission. The directories want to ensure keeping themselves clean and that is why Manual directory submission is the only practice which guarantees that the website submissions will be approved.
