About the Facebook Ad Copy Generator
Facebook Ad Copy Generator writes three different ad variants for Facebook and Instagram from a description of your product or offer. Each variant has primary text with a first sentence under 125 characters, a headline of at most 40 characters and a short description of at most 30 characters. Pick the goal, sales, leads or visits, and a tone. The ads aim to be honest: no false urgency, no before-and-after claims, no medical or income promises and no references to the viewer's personal traits, in line with common ad policies. Your text is sent to our AI service and is not stored.

The three parts of an ad
Primary text is the main message above the image. The headline sits under the image and is often read first on mobile. The description is small supporting text that may not show everywhere. Write each so it works alone, because placements differ.
Match the goal
For sales, show what the buyer gets and a clear price or offer. For leads, explain what they receive for their details, such as a free guide or a quote. For visits, tease the useful content on the page. The call to action should fit the goal and be honest about what happens next.
- Sales: product, benefit, offer
- Leads: what they get, how long it takes
- Visits: the question the page answers
Follow the rules
Advertising policies ban misleading claims, before-and-after images for some products, claims about health or income, and text that implies you know personal facts about the viewer. The copy avoids these, but you remain responsible for every claim. Keep evidence for statements you make.
Test and learn
Run each variant with the same audience and budget for a few days. Compare cost per result, not just clicks, and keep the winner. Use the Headline Generator to try extra headline wordings and the Ad Metrics Calculator to work out cost per click and return on ad spend.
Plan the whole campaign
Combine the ads with a good landing page, organic posts planned in the Content Calendar Generator and a clear product description from the Product Description Generator. Consistent messages across them make the ad more believable.

Frequently asked questions
What are the length limits?
Facebook shows only part of the primary text before a See more link, so the first sentence should be under about 125 characters. Headlines are best under 40 characters and descriptions under 30. The writer aims for those lengths, but always check in Ads Manager.
Why test more than one variant?
You cannot know in advance which wording works best. Running two or three variants against each other shows which gets more clicks or sales at a lower cost.
Will the ads pass Meta's review?
Not guaranteed. The writer avoids common problems, but policies change, and some topics need extra approval. Read the current policies and fix anything that might be flagged.
Does it mention discounts and prices?
Only if you include them in your description. Use real, current offers, and do not claim a discount that does not exist.
Can I use it for Instagram ads?
Yes. Facebook and Instagram ads use the same fields. Instagram shows less text, so lead with the strongest line.
What makes a good ad?
One clear benefit, a specific audience and a simple action. Show something real in the image or video, and make sure the landing page matches the promise in the ad.
Where should the ad send people?
To a page focused on the same offer, such as one written with the Landing Page Copy Generator. A mismatch between ad and page wastes the click.
Is my text stored?
No. It is sent to our AI service to write the ads and is not stored.
