Dorking: the use of search engines to find very specific data
There's a related thing you can do. If you have web pages somewhere, create a bunch of blank web pages with just one random word on them (something like "ristordshest") and then create an index page that links to them all.<p>Then link to that index page somewhere where noone except web crawlers will notice it. Then wait a few weeks.<p>Now when you<p>a) sell something on eBay where you are not allowed to link to the product support page page or some other stupid restriction like that<p>b) want to promote something on Instagram where you can't link to it<p>Ask people to google for the search term. There will be only one result: Yours.
