Why does the browser need metadata about the page?


There exists different categorizations of metadata but most generally metadata is “data about data”. While the browser doesn’t need most metadata it does often use metadata to enhance the user experience in some way. Metadata not displayed on a page but behind the scenes it can be used by other software (web crawlers, search engines, browsers, etc.) to process, encode, extract or index all sorts of interesting information (geographic coordinates, calendar events, contact info, etc.). What’s more, businesses are often interested in using metadata to improve SEO or Search Engine Optimization.


Does it make a difference whether metadata come before or after it?


HTML is read by the browser from the top of the document to bottom of the document. Important data (language, characters, frameworks, etc.) is stored in the section and should be as close to the top of the document as possible so the browser knows how the page should be displayed.


I just started to learn about HDML, it is very interesting stuff to learn. This is going to take a long time to learn, from what I can see is going on, there is a lot of cross references to learn. For example, after I learn about the elements reference, they are input, link, too many to mentions here.


try bookmarking all the references. I know it feels really overwhelming! I found that putting everything in a smart bookmarking list can help a lot! and take your time learning and reading those things you bookmarked :wink:


Meta tags allow the browser to display the HTML page correctly, and for search robots to correctly index and rank sites. Thus, using meta tags, webmaster reports metadata (that is, additional data that is not visible to the user) about each specific page of the site. That is why the use of meta tags for the site is so necessary. This data is only needed by crawlers https://sitechecker.pro/website-crawler/ of search engines. Users do not see them. They contain additional information that allows for automatic processing and systematization of the page in the general flow of information on the Internet.
