How it helps in SEO?
For the most part registering a webpage/website on a search engine is a simple task. All Google requires is a link from a site already indexed and the web crawlers will visit the site and begin to spider its contents. Normally a few days after registering on the search engine the main search engine spiders will begin to index the website.
