What Is Indexing?
Search Engines are these websites that help people find search results on the internet. Without Search Engines, it would be really hard to find the right site with the right info that you are looking for. You would have to type in the exact domain for the site you wanted, every time.
Search Engines have these little crawlers that crawl all over the internet, looking for new content to "Index." When a crawler ends up at your website, either because you told it to go there or it just dropped by for its weekly check up (Depending on your site age and how often you post) it will look for SEO content you wrote.
When a crawler finds some new content on your site, it will do its thing (I'm not 100% sure on its thing, but it does it) and report back to the boss. When a crawler takes your content back to the base, it gets put through an algorithm that looks at a whole bunch of things.
Your content has been indexed if it makes it back to the boss!
