Direct answer
Lead generation ads are ads that collect a prospect's contact details inside the ad itself, using a form that opens in the feed rather than sending the click to a landing page. Meta calls them instant forms, LinkedIn calls them Lead Gen Forms, and Google calls them lead form assets. All three pair a form with a standard image ad, and the creative specs differ: Meta uses its normal feed image, now recommended at 4:5 and 1440 x 1800, Google's lead form background is 1200 x 628, and LinkedIn adds a separate 552 x 200 image inside the form itself. The headline limits differ too, at 40 characters on Meta, 60 on LinkedIn, and 30 on Google. Adscreator takes one product URL and produces the image in every required crop plus copy written to each platform's limit, so one asset run covers all three.
The problem
Lead ads fail in a specific and repeatable way. The form removes the landing page, which removes the step where a prospect reads enough to decide they are genuinely interested, so volume goes up and quality goes down. Advertisers respond by adding questions until the form is a chore, which kills volume without much improving quality, because the questions ask about budget rather than about fit. The second failure is quieter: the creative is a recycled feed image that was never designed for a format where a form panel covers part of the frame and where the picture is the only thing doing any qualifying.
How Adscreator handles it
Paste a product URL or describe the offer, and Adscreator produces the lead ad set for whichever platforms you run. You get the 4:5 feed image at 1440 x 1800 that Meta now recommends, the 1.91:1 crop at 1200 x 628 that Google's lead form background and LinkedIn single image ads take, the square card at 1440 x 1440 for carousels, and the 552 x 200 form image LinkedIn shows inside the form, all on brand and composed so the subject survives the crop and the form overlay. Copy comes written to each platform's ceiling rather than to one generic length: 40 character headlines for Meta, 60 for LinkedIn, 30 for Google, with descriptions inside 200, 160, and 200 characters respectively. You get several variants per platform so an expensive B2B channel is not riding on one untested line. Pricing is flat monthly with no per-asset credits. You download the files and build the forms in your own Ads Manager, Campaign Manager, or Google Ads account. Adscreator never connects to your ad account.
specs
Meta, LinkedIn, and Google lead forms, side by side.
Every spec sheet on the web covers one of these three systems. Almost none put them next to each other, which is a problem if you run lead ads on more than one platform, because the limits are close enough to look interchangeable and different enough to truncate your copy. Figures below come from Meta's lead ad design specifications, LinkedIn's own Lead Gen Form specifications page, and Google Ads lead form asset documentation, checked in August 2026. Note the pattern: LinkedIn gives you the most room to write and the least room to ask, Google gives you the least room to write and no custom questions at all, and Meta is the permissive one on both counts.
| Field | Meta instant form | LinkedIn Lead Gen Form | Google lead form asset |
|---|---|---|---|
| Ad image | Standard feed image, 4:5 at 1440 x 1800 recommended, 1.91:1 still accepted | 1200 x 628 single image, 1080 x 1080 carousel cards | Background image at 1200 x 628 |
| Image inside the form | None, the form overlays the ad | 552 x 200 | None |
| Headline | 40 characters | 60 characters | 30 characters |
| Description or offer detail | 200 characters | 160 characters | 200 characters |
| Maximum questions | Up to 15 | 12 profile fields plus 3 custom | Chosen from Google's question library |
| Custom questions | Yes | Yes, 3, up to 100 characters each | No |
| Confirmation message | Yes | Up to 300 characters | Up to 200 characters |
| Consent and privacy | Custom disclaimers supported | Privacy policy text up to 2,000 characters, up to 5 checkboxes at 500 characters each | Your privacy policy URL, Google supplies the rest |
| Hidden fields | Supported | Up to 20 additional fields | Not supported |
Three figures here catch people out. Meta's lead ad creative is just its feed image, and Meta now recommends 4:5 at 1440 x 1800 rather than the 1200 x 628 landscape that almost every lead ad spec sheet still prints; the older size is accepted but it is no longer what Meta asks for. The 552 x 200 LinkedIn form image is a second, separate asset from the ad creative, and if you skip it the form renders with a blank space where a logo lockup should be. And Google's lead form asset takes questions only from a fixed library organized by industry, so a qualifying question you consider essential may simply not exist there. That is the strongest practical argument for running the same offer as a Meta instant form or a LinkedIn Lead Gen Form when qualification matters more than volume.
The cheapest platform for your industry is probably not the cheapest platform overall
Across all industries, published US benchmarks put a lead from Meta at roughly $27.66 and a lead from Google Search at $66.69, which reads like a settled argument for Meta. Per industry, the ranking scrambles. Attorneys and legal services are the most expensive vertical on Google Search at $131.63 per lead and one of the cheapest on Meta at $18.17, a gap of more than seven times. Real estate runs $102.51 on Google against $16.61 on Meta. Restaurants and food, $30.57 against $3.16. Then dentists invert the whole pattern: $72.97 on Google and $76.71 on Meta, the one vertical in the set where Meta costs more. The reason is intent versus interruption. A person typing a lawyer query into Google has a legal problem right now and every firm in the county is bidding on that moment, which is what makes the click expensive. The same person scrolling a feed is cheap to reach and mostly not in trouble yet, which is what makes the lead cheap and the close rate lower. Dentists break the pattern because the search intent is often routine rather than urgent, so the auction is calmer, while feed audiences for dental are heavily worked. The practical takeaway is that a cost per lead comparison across platforms is meaningless without the close rate behind it, and that the right platform is a vertical-level question rather than a general one.
Lead ad creative has a job that feed creative does not
On a traffic ad the image sells the click and the landing page does the qualifying. On a lead ad there is no landing page, so the image and the two lines above it are the entire qualifying step, and they are competing against a form that is one tap away. That changes what a good lead ad image looks like in two specific ways. First, composition has to account for the overlay. On Meta the form panel slides over the creative, so a layout with the subject or any text near the lower third gets covered at the exact moment the prospect is deciding whether to continue. Keep the subject centered and high, and treat the bottom third as expendable. Second, and less obvious, the creative should be doing some of the disqualifying. The instinct with lead ads is to widen the top of the funnel with a soft, friendly image and a generic offer, which reliably produces a lot of leads that go nowhere. Naming the buyer or the constraint in the creative itself, a price band, a company size, a specific situation, costs you volume and improves everything downstream. An ad that says commercial roofing for buildings over 20,000 square feet gets fewer form fills than one that says free roof inspection, and the people who fill it in are the ones you wanted. LinkedIn adds a third consideration, the 552 x 200 image that appears inside the form. It is small and wide, it sits at the moment of highest intent, and a logo with a short reassurance line does more there than a photograph, which at that ratio reduces to a stripe.
The 20 percent text rule has not applied since 2021 and people still design around it
Search for lead ad specs and a good share of the results still report that no more than 20 percent of a Meta ad image may be covered by text. Meta retired that rule in 2021. It no longer blocks an ad, no longer reduces delivery, and the grid tool that used to check it is gone. The rule persists in spec sheets because those sheets copy each other rather than the source, which is the same reason you will find LinkedIn vertical crops quoted as 1080 x 1350 when LinkedIn publishes 720 x 900. It matters here more than on most formats. Lead ads sell an offer rather than a product, and offers are made of words: what you get, who it is for, what it costs. Designing that headline out of the image to stay under a limit that no longer exists means giving up the one element that qualifies traffic before it reaches the form. Set the offer in the image, large enough to read at feed size on a phone, and let the primary text carry the detail. The genuine constraints on the image are the ones in the table above: the frame each platform asks for, the JPG or PNG requirement, and the fact that the form panel is going to cover part of what you made.

The features behind lead generation ads.
questions
Lead generation ads: the questions people ask.
What are lead generation ads?
Lead generation ads collect a prospect's contact details in a form that opens inside the ad, instead of sending the click to a landing page. Meta calls them instant forms, LinkedIn calls them Lead Gen Forms, and Google calls them lead form assets. Fields like name and email pre-fill from the platform profile, which is why they convert well and why lead quality needs watching.
How do I create lead generation ads on Facebook?
In Meta Ads Manager, create a campaign with the Leads objective, choose Instant forms as the conversion location, then build the ad with a standard feed image, 4:5 at 1440 x 1800, and a headline inside 40 characters. Create the instant form at the ad level, adding up to 15 questions, your privacy policy URL, and a thank you screen. Prospects submit without ever leaving Facebook.
What size should a lead generation ad image be?
It differs by platform. Meta uses its standard feed image, now recommended at 4:5 and 1440 x 1800, not the 1200 x 628 most lead ad spec sheets still list. LinkedIn single image lead ads and Google lead form backgrounds both take 1200 x 628. LinkedIn additionally needs a separate 552 x 200 image inside the form, which is a different asset from the ad creative.
How much do lead generation ads cost?
Published US benchmarks put the all industry average at about $27.66 per lead on Meta and $66.69 on Google Search. The spread by vertical is far wider than that gap suggests: legal runs $18.17 on Meta against $131.63 on Google, while dentists cost more on Meta at $76.71 than on Google at $72.97. Your own close rate decides which number is actually cheaper.
Are lead generation ads worth it?
They are worth it when your sales process can follow up quickly and qualify by phone or email, and a poor fit when you need the prospect educated before they talk to you. Removing the landing page raises form fills and lowers average intent. Businesses with a fast, staffed follow up motion win with them. Businesses relying on the lead to arrive pre sold usually do better sending traffic to a page.
How many questions should a lead generation form have?
Three to four fields is the usual recommendation, and LinkedIn states it directly in its own guidance even though it permits 12 profile fields plus 3 custom questions. Every added field cuts completion. The better lever is which questions you ask: one specific qualifying question about the prospect's situation filters more effectively than four demographic fields the platform already knows.
What is the difference between lead generation ads and traffic ads?
A lead generation ad opens a form inside the platform and the prospect never leaves the feed. A traffic ad sends the click to your website, where a landing page does the explaining and your own form collects the details. Lead ads produce more submissions at lower average intent and cost. Traffic ads produce fewer, better qualified leads and let you retarget everyone who visited.
