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.

Then link to that index page somewhere where noone except web crawlers will notice it. Then wait a few weeks.

Now when you

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

b) want to promote something on Instagram where you can't link to it

Ask people to google for the search term. There will be only one result: Yours.
