To effectively promote the website in the search engines (Bing, Google) you have to create certain files for the website.
sitemap.xml: It making sure Google can find and crawl the file that lists a website's important pages. It also helps search engines understand your website structure.
robot. txt: A robot. txt file tells search engine crawlers which URLs the crawler can access on your site. This is used mainly to avoid overloading your site with requests; it is not a mechanism for keeping a web page out of Google
SLL certificate: Websites need SSL certificates to keep user data secure, verify ownership of the website, prevent attackers from creating a fake version of the site, and convey trust to users.
In the end, you'll get correctly configured files which will help you to improve the output and also draw potential costumer’s' attention.
