Reviews, testimonials, comments on your ads, and quotes from sales calls give you hooks that sound like a real person, because a real person said them first. - A Meta ad has three text fields: primary text above the image, a headline below it, and an optional description. Meta's ads guide recommends 50 to 150 characters of primary text and about 27 characters for the headline, and the feed hides everything after the first line or two, so the hook belongs in the first sentence. - Meta mixes the text options you give it and learns which combination works, so every primary text has to read well beside every headline. - Kite finds your customer evidence, chooses three to five angles, writes a full set of primary texts and headlines for each ad, notes the source behind every line, and checks every line's length before you see it. - Your team uploads the copy in Meta Ads Manager. With your Meta Ads account connected, Kite reads how each ad performed and writes the next round from the angles that won. ## How do you write Facebook and Instagram ad copy with AI? Facebook and Instagram ads appear in a feed full of posts from friends, creators, and other brands. Your copy has about one sentence to make the right person stop scrolling and a few more to give them a reason to click. That's why most of the work happens before anyone writes a line: deciding who the ad is for, what that person cares about, and which reason to click is strong enough to lead with. If you ask a general AI chatbot for "ten Facebook ads for my product," you'll usually get ten lines that could belong to any company in your category. The chatbot doesn't know what your customers say about you, which of your past ads worked, or what your competitors are already running. The result reads like every other ad in the feed. Good AI-written ad copy follows the same process a skilled paid social marketer uses: - Collect what customers say about the problem and about your product, in their own words. - Check what competitors are running so your ads take a different angle. - Choose a few distinct angles, each a different reason to click. - Write the primary text, headlines, and descriptions for each angle within Meta's recommended lengths. - Upload the ads, let them run, and use the results to write the next round. That process is a good fit for an AI agent. It can read hundreds of reviews and comments in minutes, keep track of where each phrase came from, count characters exactly, and come back to the results after the ads have run. Kite is an AI marketer. It researches your business, builds a growth strategy, and ships the work that brings you new customers. Here's how it writes your Facebook and Instagram ads. ## How Kite writes your Facebook and Instagram ads Kite starts with what it already knows about your business from its research: your products, your customers, your positioning, and your brand voice. It then gathers the customer evidence the copy will be built from and looks at what your competitors are running on Facebook and Instagram. From that material, it chooses three to five angles and writes a complete set of text for each ad. Every line notes the source it came from, and a checker counts every line against Meta's recommended lengths. You get the batch to review in the conversation, along with a file your team can paste from in Ads Manager. Once the ads have run, Kite reads their results through your connected Meta Ads account and writes the next round: new wording for the angles that worked, a replacement for the ones that didn't, and one or two new angles to test. ### Start with what your customers actually say Kite builds every ad from customer evidence, because the words a customer chose are more specific and more believable than anything a copywriter invents. A review that says "I stopped dreading Sunday nights" makes a better hook than "Save time on bookkeeping," and a skeptical question in your ad comments often points to the objection your next ad should answer. Before writing, Kite looks for that evidence in several places: - reviews and testimonials, in your team's knowledge base or pasted into the conversation - comments people left on your past ads - quotes from sales calls and customer surveys - your own past ads that performed well, read through your connected Meta Ads account - measured results your customers have reported Kite also checks what your competitors are running. Its built-in ad research can find a competitor's current Facebook and Instagram ads from its website address, or search Meta's Ad Library by keyword to show what your whole market is saying. That tells Kite which angles are crowded and where your ads can say something different. Your competitors' claims stay theirs; Kite uses them to find contrast, not to borrow lines. When Kite can't find any customer evidence, it tells you what it searched and what would help, such as a few reviews pasted into the conversation or approval to research what customers say about you in public. If you ask it to write from your positioning alone, it will, and it marks every line so you know no customer evidence backs the batch. ### Choose the angles worth testing An angle is a reason to click, and Kite picks three to five of them before it writes any copy. Each angle comes from a different insight in the evidence, so the ads test different ideas rather than different synonyms for the same one. The angles Kite chooses from include: - the problem your customer was living with - the outcome they got - proof, such as a customer result or a specific number a customer reported - a comparison with the usual way of doing things or with an alternative - who the product is built for - an objection answered - a contrarian view your customers share An offer or deadline angle only appears when you have a real, dated offer. Kite also considers how much the reader already knows. Someone seeing your brand for the first time needs to recognize their own problem in the first line. Someone you're retargeting after a visit to your pricing page already knows the product and needs a reason to act now. ### What makes good Facebook ad copy? Good Facebook ad copy names one specific reader, gives them one reason to care in the first sentence, and keeps the promise the hook makes. Kite writes each Meta ad as a package because that's how Meta uses it. One ad can carry up to five primary texts and five headlines, and Meta shows different combinations to different people while it learns which ones work. For each ad, Kite writes: - **Two to five primary texts.** Each one makes the same argument from a different opening. One might start with the reader's problem or a customer's situation, and another with the outcome or a plain promise. - **Two headlines that do different jobs.** One states the value, and the other names the action or a specific detail. - **A description, only when it adds something.** Kite writes one when it has a specific detail or a real guarantee from your sources to add. Otherwise it leaves the field empty, because the description often doesn't show. Since Meta mixes the options, Kite checks that every primary text reads well with every headline. It drafts each hook together with the sentences that follow it, so the opening leads somewhere the rest of the ad can deliver. When you supply the image or video, Kite reads the words alongside it. The picture already shows the product, so the copy can spend its few words on what the picture can't say. Here's what a package might look like for a bookkeeping service for restaurant owners, built from a review that said, "I used to spend Sunday nights on receipts. Now I don't open the shoebox at all." - **Primary text, problem opening:** "Still spending Sunday nights sorting receipts? Our bookkeepers handle your restaurant's books every week, so your Sunday is yours again." - **Primary text, outcome opening:** "Your books, closed every Friday. We reconcile sales, payroll, and supplier bills for restaurants and send you one clear report." - **Headline that states the value:** "Your Sunday nights back" - **Headline that names the action:** "Talk to a bookkeeper" Either headline works under either primary text, and both primary texts put the hook in the first sentence. In a real batch, each line would also name the review, comment, or past ad it came from. ### How long should Facebook and Instagram ad text be? Keep primary text short enough that the hook lands before the feed cuts it off. Meta's ads guide recommends 50 to 150 characters of primary text and about 27 characters for a headline in Facebook Feed image ads. It doesn't state a hard maximum for either field, but the feed shows only the first line or two of primary text before a "more" link, and that applies on Instagram too. Whatever sits after the cut-off only reaches people who were already interested. Kite doesn't count by eye. Every line goes through a checker that counts its characters against the recommended length for its field and flags lines that run long, repeat another line in the same ad, or are missing a source. Kite fixes what the checker finds and runs it again before you see the batch. It writes every line in sentence case with straight quotation marks, which matches how most brands write and reads as a person talking rather than a billboard. ### Review the batch and launch in Ads Manager Kite delivers the copy for your team to review, choose from, and launch. The batch arrives in the conversation in the Kite web app or Slack, with the angles explained, every line and its source listed, and the checker's results attached. The same lines come in a file your team can paste from in Ads Manager. Kite doesn't create or launch ads in your Meta account. Your team picks the lines it likes, adds the landing page link, and launches in Ads Manager. If you'd rather upload in bulk, give Kite your campaign names, ad set names, and landing page URL, and it prepares a copy of the batch in the layout your import needs. Meta's own text features can rewrite your ad text after you upload it. Kite points this out with every batch, because if you want to learn which of your angles actually works, you need to turn Meta's text changes off for that test. Kite can also make the visuals. It creates and edits ad images in your brand's colors and fonts, and it produces short vertical videos for Reels and Stories using your own site's images and footage before generating anything new. ### Write the next round from your results Ad copy wears out. The same people see the same ad again and again, and the clicks fall off. With your Meta Ads account connected, Kite reads each ad's text and results over a period you choose, then uses them to write the next round. Kite sorts your current ads into the angles that earned results and the ones that didn't, judging by the measure you care about, such as cost per lead or cost per purchase. The winning angles get fresh wording. The losing ones are retired. One or two new angles go in to test. Lines that haven't had enough delivery to judge stay marked as untested, so a small sample doesn't kill a good idea. Kite never describes a line as tested when there's no performance data behind it. Kite records each round in your team's knowledge base: the period it looked at, which angles won, which it retired, and which are now being tested. Each new batch starts from everything the earlier ones taught it, instead of from a blank page. ## What you get - **A set of angles with their evidence.** Three to five reasons to click, each with the customer insight behind it and where that insight came from. - **Complete ad packages.** Two to five primary texts, two headlines, and a description where it helps, for each ad, written so every combination reads well. - **A source beside every line.** The review, comment, sales call quote, or past ad each line came from, so your team can check any claim before it runs. - **A length check.** The checker's results for every line against Meta's recommended lengths, with anything it flagged already fixed. - **Images and videos, when you ask.** Ad images in your brand's colors and fonts, and vertical videos for Reels and Stories. - **The next round.** Once your ads have run, a fresh batch built from the angles that won, with the round recorded in your knowledge base. ## How to get started Tell Kite what you're advertising and who the ad is for. You might say, "Write Facebook and Instagram ads for our spring cleaning service, aimed at busy parents," or "Give me five new Meta ad variations for our free trial." Kite tells you which customer evidence it found and which angles it plans to use. You can add reviews, point it to a past ad you liked, or change an angle before it writes. Then it delivers the batch with every line's source and length check. You don't need to connect anything for the first batch. Kite can write from your reviews and testimonials, and its built-in ad research covers your competitors' Facebook and Instagram ads. Connect your Meta Ads account when you want Kite to build on your own results, so each new batch starts from the ads that already earn customers. ## Integrations used for Facebook and Instagram ad copy Kite writes the copy, researches competitors' ads, and makes images and videos with its own built-in tools. Your Meta Ads account adds what only your account knows: how your own ads have performed. ### Learn from your own ads - [Meta Ads + Kite](/integrations/meta-ads.md): Kite reads the text, images, and results of each ad in your account, so it can tell which angles earn results and write the next round from them. Your team launches the new ads in Ads Manager. ## Common questions ### Can Kite publish the ads to Facebook and Instagram for me? No. Kite writes the copy and makes the visuals, and your team uploads and launches the ads in Meta Ads Manager. A live ad spends your money in public under your name, so the person who controls the budget makes that call. Kite reads your connected Meta Ads account for results, and it can prepare the batch in the layout your bulk import needs. ### Should I use Meta's built-in AI text tools instead? Meta's Advantage+ creative features can generate and rewrite ad text inside Ads Manager, working from the text and assets you've already given Meta. Kite starts earlier in the process. It finds what your customers say, checks what your competitors are running, chooses the angles, and writes the text Meta's tools would otherwise start from. If you use both, test Kite's angles with Meta's text changes turned off first, so you know which angle won before Meta starts rewriting it. ### Can Kite write ads in my brand voice? Yes. Kite learns your brand voice during its research of your business and keeps it in your team's knowledge base. When you correct a line or tell Kite you love one, it records that and applies it to later work. Because the hooks come from your customers' own words and the rest of the ad follows your voice, the copy sounds like your company talking to someone it understands. ### Can Kite write other ad formats too? Yes. Kite also writes Google search ads, LinkedIn ads, TikTok ad text, and X ads, each within its platform's limits.
