Hi,

My question is, Is it necessary to use Robots.txt?

[Jennifer Martin]

Yes, every website need to have either Robots.txt file or use robots tag in each and every individual page. It is used to tell search engine, which all pages of the website need to be crawled.

Also it is advisable to include XML sitemap URL at the end of robots file.

It is not important use robots. txt file but it is advisable to use it, if there is any page on your websites which you don't want search engine to crawl. Robots.txt also improves better indexing for the website.
