For advertisers
Buy the word, not the audience. When proofreading appears in an article on a site you chose, your bubble is the one that opens, and for that calendar month nobody else can buy that word on that site.
One advertiser per word, per site, per month
Exclusivity is the rule the whole system rests on. A word taken on a site is shown to other advertisers as taken, with the next free month. There is no rotation and no auction against another bidder for the same slot.
Targeting is the whole network, one category, or the sites you name.
You see the inventory before you pay
Before payment the campaign builder shows, for each word you enter, how many sites carry it and the estimated monthly page views behind it. Those counts come from the inventory index: a crawl of each verified site's sitemap that records which words appear and how often the pages holding them are read.
What a bubble contains
A headline of at most 40 characters, a body of at most 90, your display domain, and one link. The "Ad" label and the "Ads by AdBubbles" mark are fixed and cannot be changed or moved. There is no image.
Creative rules: no all-capitals, no emoji, one link, and a category from a fixed list. Prohibited categories are gambling, adult, weapons, cryptocurrency, supplements, and political.
A person reads every creative
Nothing goes live without human review. A campaign rejected in review is refunded in full. A destination URL is checked when the campaign is saved and re-checked weekly. The ad policy is the page readers reach from every bubble.
The limits of what this does
AdBubbles matches a word on a page to the advertiser who bought that word. It does not choose which people see an ad, does not follow readers between pages or sites, and does not promise a result. AdBubbles sets no cookie, stores no identifier, and collects no personal data from readers, so there is no audience segment to buy and none to be wrong about.
Your dashboard reports views, opens, clicks, open rate, and click rate, per keyword per site per day, and exports to CSV.
Building a campaign costs nothing
An account and the campaign builder are free. Enter the words, see which sites carry them and which months are free, and decide from there.
