subject: Indexing With SEO Services [print this page] Some of the most used search engines including BING, Yahoo! And Google use a function called crawler to get the web pages for the results of their algorithms. The pages these crawlers go to appear on the results of the search engine. However, if the crawler cannot find the web page of your website then it would not appear on the result page at all. Some engines, such as Yahoo! guarantee that the crawling is done for cost per click or for a set price. However, this doesn't ensure that top ranking would be acquired. In order to do so, the SEO Service provider indexes the pages (for example by using Google webmaster tools for Google) which ensure that all the pages of the site would be found easily.In order to do so, the SEO Service provider indexes the pages (for example by using Google webmaster tools for Google) which ensure that all the pages of the site would be found easily.
