Google Search Essentials
The Google Search Essentials make up the core parts of what makes your web-based content (web pages, images, videos, or other publicly-available material that Google finds on the web) eligible to appear and perform well on Google Search:
Technical requirements: What Google needs from a web page to show it in Google Search.
Spam policies: The behaviors and tactics that can lead to lower ranking or being completely omitted from Google Search results.
Key best practices: The main things that can help improve how your site appears in Google Search results.
It doesn’t cost any money to appear in Google Search results, no matter what anyone tries to tell you. It’s important to note that just because a page meets all of these requirements and best practices, doesn’t mean that Google will crawl, index, or serve its content. Learn more about How Search Works.
