I have a website (It's not a real website, but it's used here as an example). I have 10 pages on my website. 1 page no search engines can index (deep web) - it's basically "no-index" for all search engines. 9 pages can only be indexed by 75% of search engines (6 out of 8 major search engines) or these 9 pages on my website can only be indexed by these search engines. - saying there's only 8 search engines (had to find some number) 1 page - 0% can index - 100% can't 9 pages - 75% can index - 25% can't 10 pages 1 page 0% of search engines can index and 9 pages 75% of search engines can index. 1 page 0% 9 pages 75% 67.5% regular web and 32.5% deep web. ----- Now to be one of the greatest tech villians of my time... You can then throw in the loony leftism and my website now self identifies as the "dark web". As well as a "non-binary - dark web".
