The sitemaps protocol allows you to notify the search engine of the URLs available for crawling on your website. The easiest way is to use the sitemaps protocol to list XML files with all the URLs of a website. This Protocol is highly scalable and therefore applicable to websites of all sizes. It also enables the website administrator to provide other information about each website (the last update time, the frequency of changes, and its importance compared with other websites) so that the search engine can capture the website more intelligently.
Sitemaps is particularly useful when users cannot access all the regions of the website through a browser interface. (Generally, a user cannot access a specific page or area of a website through a tracking Link .) For example, any website that can only access some of its pages through a search form will benefit from creating sitemaps and submitting it to the search engine.
This file describes the format of the sitemaps file and explains the location where you post the sitemaps file so that the search engine can retrieve it.
Pay attention to adding the sitemaps protocol instead of replacing the crawling mechanism that the search engine has used to discover websites. By submitting a sitemaps (or multiple sitemaps) to the search engine, the engine can better capture your website.
Use this protocol andNoMake sure that the search index contains your webpage. (Please note that using this protocol will not affect Google's ranking of Your webpage .)
