What is Indexability?
Indexability is the ability of a webpage to be indexed by search engines.
Indexing is the process of including a webpage in a database. For example, search engines frequently crawl webpages on the internet. If they find a webpage interesting enough, they add it to their index.
Webpages and contents that get indexed can then be displayed in search results. Similarly, contents that are considered unindexable cannot be displayed in search results.
