I'm going to create a website mostly containing YouTube videos. How Google looks at indexing such a page?
Google and other search engines, taking care of the search results, want to adjust them to the expectations of Internet users. They pay attention to the content – whether what the page contains is of value to users. If this is the case, then there is nothing to be afraid of. In case of, when the content we present is very similar to this, which are presented by other websites, we are dealing with the so-called. Duplicate Content (duplicate content).
In such a situation, the search engine tries to select a page, which is the prototype, however, other pages may not be displayed. It is not a punishment of any kind. Simply, the search engine algorithm tries not to display the same content several times in the results.
