Advertising is not placed on these articles today. The pages are the notes. If advertising is approved and added later, the ads will be third-party placements, including Google advertising, and they will not be written as part of the article.
An ad, once added, may sit above, beside, or inside the article area. It should be distinguishable from the text. Clicking an ad leaves this site and opens the advertiser’s page. Spare Key Hook does not control what that page says or what it asks you to submit.
How advertising cookies would work is described on the Privacy page. You can limit Google ad personalization at Google ad settings. An ad next to a page about a key is not a locksmith and is not an offer to open your door.
