Phase 1: Foundation — Choosing the Right Extensions

Not all extensions are created equal. Your choice depends on your campaign goals, industry, and target audience. We’ll cover the most impactful types for Bangladeshi businesses.

Tactic 1.1: Sitelink Extensions

Why this works: Sitelinks allow you to show multiple links under your ad, guiding users to specific pages. They increase CTR by 10-20% and improve user experience by reducing friction.

Exactly how to do it:

1. Log into Google Ads and navigate to Ads & Extensions > Extensions.
2. Click the plus button and select Sitelink extension.
3. Enter up to 6 sitelinks with descriptive text (25 chars max for each link text).
4. Link to high-value pages: product categories, special offers, contact page.
5. Set a start and end date if running a promotion.
6. Use different sitelinks for different ad groups to maintain relevance.
7. Review performance monthly and replace underperforming links.

Pro script / template: “Shop Men’s Collection” | “Women’s Sale 50% Off” | “Free Shipping On Orders Over ৳500”

📊 Expected results: 15-25% increase in CTR within 30 days, with conversion rates improving by 10-15%.

Tactic 1.2: Callout Extensions

Why this works: Callouts highlight key selling points like “Free Delivery” or “24/7 Support” without taking up extra space. They improve ad relevance and quality score.

Exactly how to do it:

1. In Extensions, select Callout extension.
2. Add up to 10 callouts (25 chars each).
3. Include unique benefits: “Free Returns”, “Price Match”, “Local Dhaka Store”.
4. Use numbers where possible: “Over 10,000 Happy Customers”.
5. Rotate callout sets every 2 weeks to test effectiveness.

Pro script / template: “Free Delivery Dhaka” | “Same-Day Shipping” | “Trusted Since 2010”

📊 Expected results: 5-10% improvement in CTR, and higher ad rank.

Tactic 1.3: Structured Snippet Extensions

Why this works: Structured snippets provide a list of products or services organized by category, helping users quickly understand your offerings.

Exactly how to do it:

1. Choose a header (e.g., “Types”, “Brands”, “Courses”) from the dropdown.
2. Add up to 10 values (25 chars each) separated by commas.
3. For a restaurant: “Header: Cuisines” Values: “Bengali, Indian, Chinese, Thai”.
4. Ensure values are specific and relevant to the ad group.

Pro script / template: Header: “Services” Values: “Web Design, SEO, Google Ads, Social Media”

📊 Expected results: 3-7% increase in CTR and improved quality score.

Tactic 1.4: Price Extensions

Why this works: Price extensions show specific products or services with prices, attracting users ready to compare.

Exactly how to do it:

1. Select Price extension from the Extensions menu.
2. Choose the currency: Bangladeshi Taka (৳) is not available, so use USD or BDT as placeholder? Actually Google Ads supports BDT since 2022. Select BDT.
3. Enter 3-8 items with titles, prices, and links.
4. Use for product-heavy campaigns (e.g., electronics, clothing).

Pro script / template: “Smartphone X” | ৳15,000 | “Smartphone Y” | ৳20,000

📊 Expected results: 10-15% increase in conversion rate for price-sensitive customers.

Phase 2: Setup & Implementation

Once you’ve chosen your extensions, proper setup ensures maximum performance. Follow these tactics to avoid common pitfalls.

Tactic 2.1: Linking to Relevant Pages

Why this works: Each sitelink must send users to the most specific landing page. Irrelevant links increase bounce rates and waste budget.

Exactly how to do it:

1. Map each sitelink to a specific page category: “Shop Men” → /men, “Sale” → /sale.
2. Use UTM parameters to track extension performance in Google Analytics.
3. Avoid linking to the same page twice.
4. Update links monthly to reflect current promotions.

Pro script / template: “Check out our latest collection” → /new-arrivals?utm_source=google&utm_medium=sitelink

📊 Expected results: 20% lower bounce rate and higher conversion rate.

Tactic 2.2: Writing Compelling Extension Text

Why this works: Short character limits (25-30 chars) force you to be concise and persuasive. Strong action verbs and urgency drive clicks.

Exactly how to do it:

1. Start with an action verb: “Shop”, “Get”, “Save”, “Book”.
2. Include a benefit: “Free Delivery”, “50% Off”, “24/7 Support”.
3. Use numbers: “Over 5,000 Reviews”.
4. Test different CTAs: “Buy Now” vs “Explore Now”.

Pro script / template: “Save 30% Today” | “Free Consultation” | “Limited Stock”

📊 Expected results: 10-15% increase in CTR for optimized text.

Tactic 2.3: Scheduling Extensions

Why this works: Showing extensions during peak hours reduces waste and improves relevance (e.g., restaurant sitelinks at lunchtime).

Exactly how to do it:

1. Create separate extension sets for different time periods.
2. Use ad schedule to show specific extensions: e.g., “Lunch Menu” from 11 AM to 2 PM.
3. Set end dates for seasonal promotions.
4. Monitor hourly performance and adjust.

Pro script / template: Schedule “Free Delivery” extensions only during business hours.

📊 Expected results: 5-10% improvement in conversion rate during targeted hours.

Tactic 2.4: Using Mobile Preferences

Why this works: Over 60% of searches in Dhaka come from mobile. Mobile-optimized extensions ensure a seamless experience.

Exactly how to do it:

1. In extension settings, check “Mobile” to prioritize mobile users.
2. Use shorter text for mobile sitelinks (20 chars max).
3. Add click-to-call extensions for phone inquiries.
4. Test mobile preview before launching.

Pro script / template: For mobile: “Call Now” sitelink linking to tel: number.

📊 Expected results: 15-20% higher CTR on mobile.

Phase 3: Testing & Optimization

Extensions are not set-and-forget. Continuous testing is key to maintaining high performance.

Tactic 3.1: A/B Testing Extensions

Why this works: Testing different sitelink sets or callout texts reveals what resonates with your audience.

Exactly how to do it:

1. Create two extension sets (A and B) with one variable changed (e.g., callout text).
2. Run them simultaneously for at least 2 weeks to gather statistically significant data.
3. Compare CTR and conversion rate.
4. Pause the lower-performing set and create a new test.

Pro script / template: Test “Free Shipping” vs “Express Delivery” as callouts.

📊 Expected results: 5-10% improvement in overall campaign performance after 2-3 rounds of testing.

Tactic 3.2: Analyzing Performance Reports

Why this works: Google Ads provides detailed reports on each extension’s clicks, impressions, and conversions. Use them to identify winners.

Exactly how to do it:

1. Navigate to Extensions > View details to see performance data.
2. Sort by clicks or conversions to find top-performing extensions.
3. Check impression share to see if extensions are showing enough.
4. Export data to Google Sheets for deeper analysis.

Pro script / template: Use the “Extension Performance” report under Reports > Pre-defined reports > Basic.

📊 Expected results: Identify underperforming extensions and reallocate budget to high-impact ones.

Tactic 3.3: Pausing Low Performers

Why this works: Extensions that don’t drive clicks or conversions waste ad spend and may dilute your message.

Exactly how to do it:

1. Set a threshold: pause any extension with CTR below 1% after 1,000 impressions.
2. Replace with new variants.
3. Monitor the effect on overall campaign performance.
4. Repeat monthly.

Pro script / template: If a sitelink has 0 conversions after 30 days, replace it with a new offer.

📊 Expected results: 3-5% improvement in overall campaign ROI by cutting waste.

Phase 4: Advanced Strategies

Once you master the basics, these advanced tactics will give you an edge over competitors.

Tactic 4.1: Automated Extensions

Why this works: Google automatically generates extensions (like seller ratings, dynamic sitelinks) based on your account data, saving time and improving relevance.

Exactly how to do it:

1. Ensure your Google Merchant Center and Google Ads are linked for seller ratings.
2. Enable automated extensions in your campaign settings under “Extensions > Automated extensions”.
3. Monitor which automated extensions appear and override if needed.

Pro script / template: Enable “Dynamic Sitelinks” to let Google choose relevant pages from your site.

📊 Expected results: Up to 5% additional CTR without manual work.

Tactic 4.2: Dynamic Extensions for Shopping Campaigns

Why this works: For ecommerce, dynamic remarketing extensions show products users recently viewed, increasing conversion likelihood.

Exactly how to do it:

1. Set up a Google Ads remarketing tag with dynamic attributes.
2. Create a Shopping campaign with a product feed.
3. Enable dynamic remarketing in the audience manager.
4. Extensions will automatically pull products from the feed.

Pro script / template: Ensure your product feed includes all required attributes for dynamic ads.

📊 Expected results: 20-30% higher conversion rate for retargeted users.

Tactic 4.3: Combining Extensions for Maximum Impact

Why this works: Using multiple extension types together creates a larger, more informative ad that dominates the search results.

Exactly how to do it:

1. Use at least 4 extension types per ad group (sitelink, callout, structured snippet, and price).
2. Ensure consistent messaging across all extensions.
3. Prioritize mobile-friendly extensions for smartphone users.
4. Test different combinations to find the best mix.

Pro script / template: Combine sitelinks (“Shop Now”), callouts (“Free Delivery”), and price extensions to create a full-funnel ad.

📊 Expected results: 25-35% higher CTR and 15-20% better quality score.
