Tags are used in HTML website code primarily to mark website code with metadata.

Title Tag

An HTML meta tag (Title Tag) that acts as the title of a web . Typically, the title tag is the title that search engines use when displaying search listings, including strategic and relevant keywords

The title tag should also be written to make sense to people and attract as many clicks as possible. Typically, title tags should be fewer than 65 characters.

Meta tag for robots or robots.txt

The robots meta tag, or robots, is a code that provides instructions to crawlers to crawl or index the content of a web page. A robots.txt file suggests which parts of your website search engines should or should not crawl.

The robots exclusion protocol (or standard) is a text file, accessible in the root directory of a website, that tells search engine crawlers which areas of the site should be ignored.
