Pages of your website are indexed by crawler to save in its database. This saving process is called indexing. There may be hundreds of pages in your website. But every page will be indexed, it can’t be assured. To check indexing status we use this command, “site:wpexpertguides.com”. This command is used for even keyword mapping.
Indexing is a key process to get your website ranked. Your website can not get ranked until it indexed. So, you now have came to know that indexing is the first step of search engine optimization.
