Where the Amazon disclosure appears
EverySqueeze adds an affiliate disclosure on YouTube, Pinterest, Auto DM and Facebook posts with an affiliate link (#ad). You choose the Auto DM wording.
Amazon's program and the FTC both require a clear disclosure on a post carrying an affiliate link. EverySqueeze handles this differently by surface.
YouTube
Every description EverySqueeze writes with an Amazon link includes the line "As an Amazon Associate I earn from qualifying purchases." This is guaranteed — even a description template that leaves out the disclosure token still gets the line added. When the video goes out with your own link that is not an Amazon one (for example ShopMy, LTK or a brand's site, set with Use my own link), the description gets "I may earn a commission from purchases made through this link." instead, because the Amazon line would not be true next to that link. The line goes in the block with your link, near the top. A #ad, "affiliate" or "sponsored" in your caption does not replace it. Only a caption that already has the Associates sentence (or, with your own link, a commission sentence such as "I may earn a commission") skips ours, so it is never there twice.
Pins EverySqueeze posts carry the same "As an Amazon Associate I earn from qualifying purchases." line in their description, with your caption hook and hashtags, and it is never the part that is cut when a long caption is shortened. A Pin that links to your own non-Amazon link carries "I may earn a commission from purchases made through this link." instead.
Auto DM
Under Disclosure on the Facebook card in Settings → Auto DM, you choose one of four disclosures that ends every DM: #ad (recommended, the shortest and named as clear by both the FTC and Amazon), (paid link) (Amazon's own example), (I may earn a commission) (plain wording close to the FTC's suggestion), or #afiliado (the word Spanish-speaking creators use, for a Spanish-speaking audience).
Facebook captions
A Facebook post that carries an affiliate link ends its caption with #ad, just before the link, unless your caption already discloses (it says #ad, affiliate, afiliado, commission, Amazon Associate, paid link or sponsored). That is your Amazon link, and also your own link set with Use my own link (for example ShopMy, LTK, TikTok Shop, Walmart or a brand's site), because it earns you a commission the same way. A plain link to one of your TikTok videos is not an affiliate link and gets no #ad. It is on by default. Turn it off with the Add #ad to Facebook posts with an Amazon link switch (it covers your own links too): on the desktop in the Links & disclosure group of Settings → Accounts & platforms → Facebook, and on the phone in the Facebook settings under Where to put your Amazon affiliate links. It applies while Amazon link in the caption is on, and the post preview shows the #ad. See Where your Amazon link goes on Facebook.
In the caption box
When you post a video yourself, the Composer's caption box (and the phone app's Posts tab) starts with #ad at the end only for a video that sells something: a TikTok Shop product, an Amazon product or your own link. A video with nothing to sell starts with its caption only, and with adding #ad turned off (the switch above) the box never adds it. You can always type your own. A post you schedule from that box keeps its #ad on Facebook, Instagram and YouTube when it goes out, the same as Post now, even when the link goes in the first comment or isn't an Amazon link (unless you turn adding #ad off before it posts).
The YouTube title
A YouTube post EverySqueeze makes automatically takes its title from your TikTok caption and adds no #ad to it. When you post or schedule a video to YouTube yourself on a computer, the YouTube window starts its Title from the beginning of the post's caption box, up to about 90 characters. That box ends with #ad for a video that sells something (see In the caption box above), so a short caption gives a title that ends in #ad too. Keeping it there is your choice: the description already carries the disclosure line when it has your link (see YouTube above). To leave it out, delete it from the Title before you post or schedule. In the phone app, the YouTube title box on the video's card starts from your TikTok caption without #ad, and what's in that box is the title (left empty, the caption is used).
Instagram captions
Instagram captions don't carry an Amazon link, and the caption template doesn't offer a disclosure token (only YouTube's editor does). If you want a disclosure in an Instagram caption, add your own wording, such as #ad, to your caption text.
Instagram also has its own Paid partnership label. Where it is on for your account, EverySqueeze can ask Instagram to add it to posts that carry a product: see how the label setting works. The label is Instagram's; your caption wording is still yours to decide.
Who can change these switches
Add #ad to Facebook posts with an Amazon link, the Paid partnership label switch for Instagram and YouTube's paid promotion switch belong to the account owner. An assistant sees them locked with Only the account owner can change this.; a try anyway changes nothing and shows in the owner's activity list. Caption wording and templates stay open to an assistant.
