Recommendations Wanted For Websites Suitable For Our Advertisements

We have previously advertised in the Canadian newspaper Druthers which has bought in hundreds of new users.

We would now like to bring in more unvaccinated users from the USA and possibly Europe. From social media and search engines, we get a trickle of a few new users every day. We would like to speed that up.

Please tell us if you know of any good websites with a decent sized audience who would display our adverts. At the time of writing, our website is mostly free to use and so our budget is limited.

Some websites accept advertisements but charge for impressions (each time an advert is displayed on a web page viewed by a user) rather than actual clicks on adverts. We would like to avoid these websites.
