Lead form assets: capturing leads without a landing page in 2026

Imagine this: a potential customer sees your Google ad, is interested, clicks, and then abandons the journey halfway to your website. The landing page loads too slowly, the form is too long, or the screen on their phone is simply too small for all those fields. The lead is lost. This is one of the most common conversion problems in lead generation campaigns, and lead form assets solve it directly. In 2026, lead form assets are one of the most powerful tools for advertisers who want to generate quality leads quickly and with minimal friction, straight from the ad itself, without the user ever having to navigate to a separate landing page.

What are lead form assets?

• Average 2-3 steps to complete
• Optimised for mobile use
• No page load issues
• Automatic CRM connection via webhook
• Lower CPL due to less friction

Lead form assets (formerly known as "lead form extensions") are interactive forms attached directly to a Google Ads ad. When a user clicks on the call-to-action, a form opens within the Google interface itself. The user never leaves the search environment and never has to navigate to an external website. Google also automatically pre-fills many fields with data the user has already saved in their Google account, such as name, email address and phone number. This pre-fill functionality is one of the biggest drivers of the higher conversion rates that lead form assets achieve compared to traditional forms.

Lead form assets are available across multiple campaign types: Search, Display, Discovery and Video. This makes them highly versatile, whether you want to capture intent-driven queries in the search network or reach a broader audience via YouTube or the display network. The information you collect is configurable: name, email, phone, company name, postcode and even specific qualifying questions are available as input fields. After submission, the user can optionally be redirected to a thank-you page, or simply remain within the Google environment.

Collected lead data is available via the Google Ads interface as a CSV download, but the most powerful integration runs via a webhook or a direct connection with your CRM system through tools like Zapier, HubSpot or a custom integration. This way, new leads land in your sales pipeline within seconds, ready for follow-up.

When do lead form assets work best?

Lead form assets are not the right fit for every situation. There are specific contexts in which they structurally outperform traditional landing pages:

• Mobile campaigns: On smartphones, filling out forms on external landing pages is notoriously difficult. Lead form assets are fully optimised for mobile and combine that with Google pre-fill, making the threshold minimal.
• High-intent searches with a short sales funnel: Services like air conditioning installation, heat pump quotes or similar local services where users want quick contact benefit strongly from the direct form opening.
• Situations without a strong landing page: Not every advertiser has an optimised, fast-loading landing page available. Lead form assets then offer a high-quality alternative without major investment in web development.
• Top-of-funnel lead generation for YouTube or Display: When activating a cold audience via video or banner ads, an in-ad form dramatically lowers the step to conversion.
• Campaigns focused on speed of follow-up: With a direct webhook connection to your CRM, a sales team can call the lead within minutes while intent is still fresh.

A strong example is Clima-Active.nl, an air conditioning and heat pump installer that generates quote requests via Google Ads. In a market where consumers compare multiple quotes, speed is critical. A lead form asset combined with a direct CRM connection ensures that Clima-Active's sales team can contact the lead while the potential customer is still actively comparing options.

Setting up lead form assets: step by step

Creating a lead form asset in Google Ads follows a structured process. Here are the steps to set up an effective form:

1. Choose the right campaign type: Lead form assets work with Search, Video, Display and Performance Max campaigns. Ensure your campaign objective is set to "Leads".
2. Add the asset: In campaign settings, navigate to "Assets" and choose "Lead form". Click the plus button to create a new form.
3. Write a compelling headline and description: The form headline is the first thing users see when the form opens. Make it specific and value-driven, describing what the user receives after submitting.
4. Select the right fields: Keep the form as short as possible. Name, email and phone are sufficient in most cases. Every additional question raises the drop-off threshold.
5. Add a privacy policy URL: This is mandatory. Google requires a valid link to your privacy policy before the form can be approved.
6. Set up the thank-you page: Choose a relevant thank-you message and consider redirecting to your website for further content consumption.
7. Connect a webhook or download leads regularly: Set up a webhook for direct CRM integration, or establish a process to regularly export leads from the Google Ads interface.

A common mistake is adding too many fields. Industry benchmarks consistently show that forms with more than four fields have significantly higher drop-off rates. Keep it minimal and only add qualifying questions when lead quality is a bigger problem than volume.

One of the most frequently cited concerns with lead form assets is lead quality. Because the submission threshold is low, a lead form asset can sometimes attract less qualified enquiries. This is a real consideration, but it is manageable with the right settings and approach.

There are three primary strategies to improve lead quality with lead form assets:

• Add qualifying questions: Google allows you to add custom questions. A question like "When would you like the installation carried out?" or "What is your estimated budget?" quickly filters out non-committed searchers.
• Raise intent through ad copy: Ensure the ad text already sets expectations. Mention a price range or a specific service so that only genuinely interested users open the form. This acts as a pre-qualification step before the form.
• Guide Smart Bidding on lead quality: By feeding lead qualification signals back to Google via conversion adjustment or offline conversion import, Smart Bidding learns which type of user actually converts. Over time, optimisation shifts toward higher-quality leads.

For E-4motion.com, the webshop for new electric folding bikes, monitoring lead quality for test ride requests is essential. By specifying in the ad copy that this is a test ride with a new electric folding bike, the audience is already pre-filtered. People who respond are genuine purchase candidates, not merely curious visitors. A qualifying question like "In which region do you live?" also helps E-4motion's sales team assign leads to the right geographic zone efficiently.

Lead form assets offer enormous opportunities for lead generation, but the value depends heavily on how you manage, test and optimise them. Manual management quickly leads to stagnation: the same form text runs for months, lead quality issues go unnoticed until too late, and the link between Smart Bidding and actual lead value is missing. AdBrains solves this with a layered AI approach specifically tuned to the behaviour and dynamics of lead form assets.

The foundation is the multi-agent verification system: four independent AI agents analyse every optimisation decision before it is executed. For lead form assets, this system checks whether form changes might negatively affect an ongoing Smart Bidding phase, whether a headline update improves Ad Strength, and whether the conversion setup is still correctly configured after a campaign change. This prevents costly errors that occur regularly with manual management.

The RSA improvement system at AdBrains is also applied to analyse the headline and description of lead form assets. When the AI detects that the form text is generic or does not align with the search intent of the best-performing keywords, the system automatically generates improvement proposals. This delivers a better match to user intent and increases the form opening rate.

The automatic tCPA optimisation of AdBrains plays a similarly crucial role. Based on daily incoming leads, qualification status fed back from the CRM, and margin targets per client, the AI continuously adjusts the Target CPA. For Clima-Active.nl, this means the AI raises the target in periods when the sales team reports high lead quality, and corrects course when the share of unqualified leads temporarily increases. This level of precision management is not scalable manually.

The server-side signal enrichment system of AdBrains provides continuous enrichment of conversion signals via its own sGTM infrastructure. Offline conversion imports are automated, so Smart Bidding always has the most current and complete signals about which leads actually converted to customers. This structurally improves the relevance of the bidding model and delivers a lower Target CPA over time at maintained or improved lead quality.

Finally, the automated search term mining of AdBrains monitors which search terms lead to form openings. Terms that generate many form submissions but low qualification rates are analysed and added as negative keywords where appropriate. The AI continuously refines incoming traffic without requiring an account manager to manually sift through hundreds of search terms every day.

Lead form assets and conversion tracking

Correct conversion tracking is the backbone of every successful Google Ads campaign. With lead form assets, this works differently than with standard form conversions on a website. The conversion is registered at the moment the user submits the form within the Google interface. Google Ads recognises this automatically and registers the conversion as a "Lead form submission".

Still, there are additional steps that significantly improve the quality of your conversion data:

• Import offline conversions to track which leads actually become customers. This gives Smart Bidding the signals to optimise on real revenue, not just form submissions.
• Use Enhanced Conversions where possible to strengthen first-party signals in your conversion tracking setup.
• Segment your conversion data at campaign and ad level to understand which combinations of ad copy, audience and search term produce the most valuable leads.

The table below provides an overview of the key characteristics of lead form assets versus traditional landing page forms, across the dimensions most relevant to lead generation.

FAQ: lead form assets in Google Ads

What is the difference between a lead form asset and a regular call-to-action in an ad?

A standard call-to-action in an ad sends the user to an external landing page. A lead form asset opens an input form directly in the Google interface, without the user leaving the search environment. This significantly reduces friction and is particularly advantageous on mobile. The user does not need to load a page and Google automatically pre-fills known details via its pre-fill functionality.

Are lead form assets suitable for both e-commerce and lead generation?

Lead form assets are primarily designed for lead generation, but e-commerce businesses with a service dimension can also use them effectively. E-4motion.com, the webshop for new electric folding bikes, uses lead form assets for test ride requests: a contact moment that can later result in a purchase. For purely transactional e-commerce without a contact moment, lead form assets are less relevant.

How do I ensure leads are followed up quickly?

The fastest solution is a webhook connection to your CRM. Via a webhook, new leads are forwarded to your CRM system within seconds, so your sales team receives an immediate notification and can call right away. Alternatives include integrations via platforms like Zapier or Make.com. The CSV export is less suitable for fast follow-up: the export must be manually initiated and leads may be hours old by the time the sales team sees them.

How many fields should a lead form have for the best results?

Industry benchmarks in 2026 consistently show that forms with two to three fields achieve the highest conversion rates. Name, email address and phone number are sufficient in most B2C lead generation cases. If you want to improve lead quality, add at most one qualifying question. Every additional question raises the drop-off threshold. If lead quality is a bigger problem than volume, it is better to attract higher-quality traffic through your keyword and audience strategy rather than lengthening the form.

Can I combine lead form assets with Smart Bidding on Target CPA?

Yes, and this is actually the recommended approach. Smart Bidding on Target CPA works best when you have sufficient conversion data. Because lead form assets in many cases deliver higher volume throughput than landing page forms, you reach the minimum of thirty conversions per month that Google recommends for Smart Bidding more quickly. Combine this with offline conversion import to guide Smart Bidding on qualified leads rather than mere form submissions, and you extract maximum value from the combination.
