Open Directory Project-Supplementary information
The submission of your site to open directory project can bring positive outcomes for you sites. Let us discuss how this takes place. The search engine sends out a spider (a computer program) to different websites to surf and search the web and, thus, listing the matching results after creating an index whereas the searches in directories are done manually by human editors who review and categorize the websites and does the listing and indexing in the directory databases.
The above mentioned methods are not applicable for every search engines and directories. Few search engine sites share a common search engine. Both search engines and directories offer paid placement viz. the websites had to pay for their listings into the search engine sites and directories.
Some search engine sites and directories display the paid websites at the top of the listings and some provides a special pace to them. Hiring several editors is too expensive for the directories.
