Above xml tag explain search engines the URL to be indexed, its last modified data, how frequently this page changes and what is the priority of this webpage to be indexed again.
Meta Robots Tag
When search engine visit any webpage they look for this meta robot tag. This tag directs them if they are allowed to index this webpage or not. Below is a sample that how meta robots tag looks like.
<meta name=”robots” content=”noindex, nofollow” />
Above tag will revoke all visiting search engines from indexing that webpage where it presents.
Note: If a webpage does not have a meta robot tag, that page will be treated as “inde, follow” by default.
Robots.txt, located in root directory of website, is a powerful method to allow or disallow search engines from indexing website at massive levels.
