The Google Ads Lead Form Extension offers an effective way to capture leads directly within search, video, or Discovery ads. How does lead capture work without a landing page? This extension has enormous potential to increase lead generation in the areas of search engine advertising (SEA) and online marketing.

Especially in Google Ads campaigns, the Lead Form Asset plays a central role in boosting efficiency. Despite its potential, many advertisers are still unfamiliar with this feature. When combined with a CRM system like HubSpot, Lead Forms reach their full potential: they enable seamless automation and lead qualification.

What is the Google Ads Lead Form?

What exactly is the Lead Form Extension? The Google Ads Lead Form (also known as the Lead Form Extension or Lead Form Asset) is a feature that allows you to integrate forms directly into a Google ad as an ad extension.

The Lead Form Extensions appear directly on the search results page. Users can immediately provide information such as their email address without having to visit a separate website. What are the benefits of integrating with a CRM? The integration with a CRM system enables real-time data transfer and greatly simplifies lead management.

When creating a lead form, companies can select assets such as a title, description, and an appropriate call to action (CTA). An engaging call to action is crucial for increasing the conversion rate.

Benefits of Lead Forms

Why is lead capture directly within search so efficient? Lead forms offer companies numerous advantages:

  • Low barriers to entry: Contact information is collected directly in Google Search without redirecting to the website. This significantly lowers the barrier for potential customers (low friction).
  • Better user experience: The process is specifically designed for quick data collection, which reduces abandonment rates.
  • Mobile optimization: This increases the conversion rate, especially on mobile devices, since the entire process takes place directly within the ad.
  • Targeted Approach: The information requested can be customized to the company’s specific needs.

The result: Fewer bounce rates, more qualified leads and an optimized marketing strategy.

Applications and Formats

In which ad formats can Lead Forms be used? Lead Forms can be combined with various ad types:

  • Search ads: Particularly effective for search terms that indicate a clear intent to buy or contact.
  • Video ads (YouTube): Enable lead generation directly during the video (currently still in beta).
  • Discovery ads: Utilize visual placements on Gmail, YouTube, and in the Discover feed.

When creating forms, assets such as the title and description can be customized. A compelling call to action is crucial here to give users a clear prompt to take action and encourage interaction.

When is it appropriate to use it?

When is the lead form extension particularly useful? It’s especially suitable when the focus is on short-term lead generation, there’s no mobile-optimized landing page, or a particularly low-barrier conversion is desired.

Various configuration options are available to help you use lead forms flexibly in your online marketing efforts. For complex B2B processes, however, the Ads Lead Form should be well integrated into a more comprehensive lead nurturing system to ensure the quality of the inquiries.

Integration with HubSpot via middleware solutions

A key argument for using the Google Ads Lead Form is its ability to integrate directly with CRM systems such as HubSpot.

Middleware solutions ensure that leads from Google Ads are automatically fed into HubSpot and can be further processed there—including lead scoring, workflows, and follow-ups. This creates a seamless process from the first click to a qualified marketing lead (MQL).

Best Practices for Implementation

How do you optimize a Google Ads lead form for the best results?

  1. Keep the form design simple: The fewer fields (e.g., just name/email), the higher the conversion rate.
  2. Communicate your offer clearly: Spark interest by clearly demonstrating added value (e.g., a white paper or a free consultation).
  3. Choose the right lead form type: Choose between “Higher Volume” or “Higher Quality.”
  4. Customize the CTA & assets: Use the option to select a specific Call to Action.
  5. Note the aspect ratio: When adding images, make sure to use the correct aspect ratio (e.g., 1.91:1).
  6. Automate follow-ups: Integration with HubSpot ensures a quick response (“Speed to Lead”).

Conclusion: More leads through targeted use of the Google Ads Lead Form

The Google Ads Lead Form is a powerful tool for digitizing sales processes. When combined with HubSpot, you can set up automated lead processing workflows that are not only efficient but also scalable. The Lead Form extension is a highly efficient addition, especially for companies looking to modernize their marketing and sales processes.
