There are two ways a search engine can find a website to add to its listings. The first method is to accept submissions from website designers and optimisers like Cork Web Design. When we complete and launch a website we submit it to the search engines and tell the search engines that your website exists and that we want to list it.
The second, and least obvious method of finding websites is to send a "spider" to follow each and every link on, off, and through a website. New URLs encountered by the spider will be added to the database. In this way, some search engines will grow very rapidly.
It can take a number of weeks for your website to start appearing in Google. This is because there are so many websites on the internet that it takes a bit of time for their automated spiders to come to your website and list your pages.
