Critical Minerals: Google Ads Extensions for 2026

In 2026, the competitive digital advertising space demands every possible advantage, and for campaigns centered on high-value products like critical minerals, effectively using ad extensions in platforms like Google Ads is not merely an option, it is a strategic imperative for performance. These small additions to your search ads expand their real estate on the search results page, offering more information and compelling users to click. How can advertisers maximize these often underutilized tools?

Setting Up Foundational Ad Extensions in Google Ads

The journey begins in the Google Ads interface, specifically within the “Ads & Extensions” section. I consistently advise clients to start with a strong set of foundational extensions before diving into more specialized options. These are the workhorses that provide immediate value and context to your primary ad copy.

Working through to the Extensions Interface

From your Google Ads dashboard, select Campaigns from the left-hand navigation menu. Then, click on Ads & Extensions. Within this section, you’ll see three tabs: “Ads,” “Extensions,” and “Automated extensions.” Select the Extensions tab. Here, you’ll find a blue plus icon (+) to add new extensions. Click this to reveal a dropdown menu of available extension types.

Implementing Sitelink Extensions

Sitelink extensions are perhaps the most straightforward yet powerful. They allow you to add additional links beneath your main ad, directing users to specific pages on your website. For a critical minerals supplier, these might be pages for “Lithium Deposits,” “Rare Earth Processing,” or “Investor Relations.”

1. Select Sitelink extension from the dropdown menu.
2. Choose whether to apply the sitelink at the account, campaign, or ad group level. For critical minerals, I generally recommend campaign-level application for broader reach, reserving ad group level for highly specific product lines.
3. Click New sitelink.
4. Enter the Sitelink text (e.g., “Cobalt Supply Chain”). This should be concise and compelling.
5. Provide the Final URL (e.g., https://yourcompany.com/cobalt-supply-chain). Ensure this URL is direct and relevant to the sitelink text.
6. Add two lines of Description text. This is your opportunity to elaborate. For example, “Explore our ethical sourcing and strong logistics for cobalt.”
7. Repeat for at least four sitelinks. Google can show up to six on desktop and eight on mobile, so providing more options increases your chances of displaying a wider array of information.

Pro Tip: Monitor the performance of individual sitelinks. If “Investor Relations” consistently shows a low click-through rate compared to “Product Specifications,” consider pausing or revising it. According to Statista data from 2024, advertisers who actively optimize their sitelinks can see up to a 10% improvement in overall ad performance.

Enhancing Ad Messaging with Callout and Structured Snippet Extensions

Beyond direct links, conveying key selling points and detailed information is important. Callout and structured snippet extensions excel at this, providing additional text that highlights specific features or aspects of your business.

Deploying Callout Extensions

Callout extensions are short, non-clickable phrases that appear below your ad copy. They are ideal for broadcasting unique selling propositions or benefits. For a critical minerals firm, these might include “Sustainable Sourcing,” “Global Logistics Network,” or “ISO Certified Quality.”

1. From the Extensions tab, click the blue plus icon and select Callout extension.
2. Choose the appropriate level (account, campaign, or ad group).
3. Click New callout.
4. Enter your Callout text (e.g., “Advanced Extraction Technologies”). Aim for 25 characters or less.
5. Add multiple callouts. Google will dynamically select which ones to show based on relevance and available space.

Common Mistake: Many advertisers simply repeat information already in their main ad copy. Callouts should add new, compelling reasons to click. Think of them as bullet points for your value proposition.

Configuring Structured Snippet Extensions

Structured snippets allow you to show specific aspects of your products or services using predefined headers. This is particularly useful for critical minerals, where specific types or applications are often searched for.

1. Click the blue plus icon and choose Structured snippet extension.
2. Select the header type that best fits your information. For critical minerals, “Types,” “Models,” “Services,” or “Amenities” (if referring to facilities) are often appropriate. For example, choose Types.
3. Enter your values. If you chose “Types,” your values might be “Lithium,” “Cobalt,” “Graphite,” “Nickel,” “Rare Earth Elements.” Each value should be distinct and relevant.
4. Add multiple structured snippets with different header types if applicable. For instance, another snippet could use the “Services” header with values like “Geological Survey,” “Refinement,” “Distribution.”

Expected Outcome: Structured snippets give searchers a quick overview of your offerings, potentially increasing clicks from highly qualified leads who know exactly what they are looking for. A recent IAB report from Q3 2025 indicated that ads using structured snippets saw a 7% higher conversion rate on average for B2B searches.

Using Location and Call Extensions for Direct Engagement

For businesses that operate with physical locations or rely heavily on direct communication, location and call extensions are indispensable. They bridge the gap between online search and offline interaction.

Implementing Location Extensions

If your critical minerals operation has physical offices, processing plants, or distribution centers, location extensions are vital. They display your address, a map link, and distance to the user, directly in your ad.

1. Before you start, ensure your business is verified in Google Business Profile. This is a prerequisite.
2. From the Extensions tab, click the blue plus icon and select Location extension.
3. Link your Google Business Profile account. If you manage multiple locations, you can select specific ones to display.
4. Google Ads will automatically pull location information. You can then review and select which locations should appear with your ads.

My Opinion: For global critical minerals companies, this might seem less relevant than for a local retail store. However, for specific regional sales offices or critical processing facilities, it provides a tangible presence, building trust and facilitating direct visits for high-value inquiries. Imagine a buyer in Atlanta searching for “Georgia lithium suppliers”. A well-placed location extension could direct them to your local sales office in the Perimeter Center area.

Adding Call Extensions

Sometimes, a direct phone call is the most efficient way to convert a lead, especially for complex B2B transactions involving critical minerals. Call extensions add a clickable phone number to your ad.

1. From the Extensions tab, click the blue plus icon and select Call extension.
2. Choose the level for your extension.
3. Enter your Phone number.
4. Select your Country.
5. Decide whether to use Call reporting. This is highly recommended as it allows you to track calls as conversions.
6. Set Device preference. While desktop users can click to call, this extension is most impactful on mobile devices.
7. Specify Advanced options like call scheduling. For a B2B audience, only displaying the number during business hours (e.g., 9:00 AM to 5:00 PM EST) prevents missed calls and negative user experiences.

Expected Outcome: Call extensions can significantly boost conversion rates for industries where immediate contact is valued. According to Google Ads documentation, call extensions can increase click-through rates by several percentage points, particularly on mobile.

Exploring Advanced and Automated Extensions

As the digital advertising field evolves, so do the capabilities of ad extensions. Google Ads now offers more dynamic and automated options that can further enhance performance with minimal manual effort.

Using Price Extensions

While often associated with retail, price extensions can be surprisingly effective for critical minerals, especially when offering standard grades or bulk pricing for specific materials. They allow you to display specific product or service prices directly in your ad.

1. From the Extensions tab, click the blue plus icon and select Price extension.
2. Choose your Type (e.g., Brands, Services, Products, Product tiers). For critical minerals, “Product tiers” or “Products” are often suitable.
3. Set your Currency and Price qualifier (e.g., “From,” “Up to,” “Average”).
4. Add Header, Description, and Final URL for each item. For example, “Lithium Carbonate,” “High purity, industrial grade,” and a direct link to the product page.
5. Repeat for up to eight items.

My Advice: Use price extensions judiciously. If your pricing is highly variable or requires a custom quote, this extension might not be appropriate. However, for transparent pricing of specific grades or minimum order quantities, it pre-qualifies clicks and improves the user experience.

Using Dynamic Structured Snippets and Callouts

Google Ads can automatically generate structured snippets and callouts based on your website content. These “automated extensions” save time and can capture information you might overlook.

1. Navigate to the Automated extensions tab within the “Ads & Extensions” section.
2. Review the automatically generated extensions. You can choose to pause or remove any that are irrelevant or inaccurate.

Critical Warning: While automated extensions are convenient, they are not a replacement for carefully crafted manual extensions. Always review them to ensure they align with your brand messaging and accurately represent your offerings. I have seen instances where automated snippets pulled outdated or irrelevant information, which can damage credibility. Manual oversight remains paramount.

Monitoring and Optimizing Ad Extension Performance

Setting up extensions is only half the battle. Continuous monitoring and optimization are essential to ensure they are driving results and contributing positively to your campaign goals.

Accessing Extension Performance Data

Within the Extensions tab, you’ll see performance metrics for each extension type. This data includes impressions, clicks, click-through rate (CTR), and cost. You can also view granular data for individual sitelinks, callouts, and structured snippet values.

1. Select the specific extension type you want to analyze (e.g., “Sitelinks”).
2. Adjust the date range to observe trends over time.
3. Segment your data by device, network, or time to identify performance variations.

Actionable Takeaway: Pay close attention to the Click Type report. This shows you whether users clicked on your main ad headline or on a specific extension. A high percentage of clicks on extensions indicates they are effectively capturing user interest and providing relevant information.

Iterative Optimization Strategies

Optimization is an ongoing process. Based on your performance data, make informed decisions:

• Pause Underperforming Extensions: If a specific sitelink or callout consistently has a low CTR or is not leading to conversions, pause it.
• Test New Copy: Experiment with different sitelink texts, callout phrases, or structured snippet values. A/B testing can reveal which messages resonate most with your target audience.
• Refine Scheduling: Adjust call extension schedules based on when your target audience is most likely to call.
• Improve Relevance: Ensure your extensions are highly relevant to the keywords in their respective ad groups. For example, if you have an ad group for “lithium ion battery components,” ensure you have structured snippets listing those specific components.

By treating ad extensions as dynamic components of your advertising strategy, rather than static additions, you can continuously refine your approach and ensure your critical minerals campaigns achieve maximum visibility and engagement.

Mastering ad extensions in Google Ads provides a tangible competitive edge, particularly for niche markets like critical minerals where precise information and direct engagement are paramount. By systematically implementing, monitoring, and optimizing a diverse range of extensions, advertisers can significantly enhance ad visibility, improve click-through rates, and in the end drive more qualified leads to their businesses.
