The objective of discovering new URLs from links is to help web surfers locate new content in Google search results as soon as they “go” on-line. Very recently, Google has introduced a new feature that implements RSS and Atom Feeds for content publication and facilitates checking of new content from publishers. The traditional crawlers have become outdated in the face of such updated “feeds” which allow users to index web pages more quickly. There are numerous sources that Google uses to find new pages from the link provided by the URLs on the web. These potential sources are used to access updates from “feeds” including readers or direct crawls or “feeds”. However, it should be remembered that RSS / Atom Feeds also allow crawling those files by Robot.txt. To discover whether Google Bot can crawl the “feed” and find pages quickly, it is best to test the “feed” URLs with Robot.txt tester available in Google Webmaster tools.
Once the client adds the URL on Google search engine, they can share their place on the Internet. Each time Google crawls the web they update new sites and add these to their index. However, they are unable to enlist all the submitted URLs in their index and do not guarantee their appearance on the search results page. Clients desirous of getting preference by Google to appear on their search results should enter the full URL including http://prefix. The web client is advised to add comments and keywords as well as give a descriptive account of the web content. Such indices are utilized for information and have no relation to whether the page is being indexed or used by Google. Generally, the top level page of the content from host is required. But there is no need to submit individual pages. Crawling of the remaining pages is achieved by the crawler Google Bot. As Google frequently updates the index sites, it minimizes clients’ responsibilities of updating and removal of outdated links.
The links which are of no value to users would automatically “fade out” from Google index while updating the entire index. Google has many guidelines to assist the web clients. To categorize those sites submitted by individuals and those entered automatically by the software “robots”, it is important for surfers to type few letters as shown in Google pages. If the web client is interested in removing their content inclusive of pages and images, etc. from Google index, they should incorporate some alterations on the site and wait for Google to crawl the site again. The whole process could be expedited by using the URL removal tool available in Google Webmaster tools. However, if the client wants its users to be directed to a particular URL in the site then the removal tools should not be used.
To prevent search engines from crawling any content of a site the Robot.txt file or “no index” Meta Tag tool has to be used. The former tool has the ability to restrict access to the site while the other tool is a “no index” Meta Tag and restricts the content from being indexed.
