There are many factors that influence a website’s placement on Google. The exact algorithms used by the world’s top search engine are a company secret, and Google does not guarantee the time it takes for a site to be indexed. It is not uncommon for a new website to appear on Google after several days. Some sites, however, may take weeks to be discovered, or may be rejected by Google.
Basics of Google Crawling
A website does not instantly appear on Google as soon as it is built. First, Google must discover and index your website. The most common way for the search engine to find a site is with a “Googlebot,” also known as a spider. You can think of a Googlebot as a virtual robot, which wanders the Internet automatically. Spiders are programmed to quickly moved from page to page, recording what they find. They follow nearly every web link they encounter, and are constantly on the search for new content.
