Generate Google Ads Sitelink Extensions Using AI

Tested prompts for ai sitelink extension generator google ads compared across 5 leading AI models.

BEST BY JUDGE SCORE Claude Opus 4.7 8/10

Sitelink extensions are one of the highest-leverage elements in a Google Ads campaign. They expand your ad's footprint on the search results page, drive clicks to specific landing pages, and improve Quality Score by showing Google your site has depth. But writing them is tedious: each sitelink needs a short headline (25 characters max), two optional description lines (35 characters each), and a destination URL, and you typically need 4 to 8 of them per campaign. Most advertisers either rush them or skip the descriptions entirely, leaving performance on the table.

If you searched for an AI sitelink extension generator, you are probably staring at a new campaign setup or an audit that flagged missing or weak sitelinks. You need multiple distinct, character-compliant sitelinks fast, without writing each one from scratch. That is exactly what a prompted AI model can do: take your campaign context and return ready-to-use sitelink copy in the right format.

This page shows you a tested prompt you can run in any capable AI model, compares outputs across four models, and gives you the context to evaluate and apply the results correctly. You will leave with sitelinks you can paste directly into Google Ads Editor or the campaign builder.

When to use this

Use an AI sitelink generator when you are building or refreshing Google Ads campaigns and need multiple sitelinks quickly without sacrificing copy quality. It works especially well when you have a clear product or service offering and can describe your key landing pages, because the AI needs that context to produce relevant, non-generic output.

Launching a new campaign and need 6-8 sitelinks with descriptions before going live
Auditing an existing account where sitelinks are missing description lines or repeat the same messaging
Running campaigns across multiple product lines and need distinct sitelink sets for each ad group
A/B testing sitelink copy and need variant versions quickly without briefing a copywriter
Scaling Google Ads management across multiple clients and need to produce campaign assets faster

When this format breaks down

Your campaign targets a highly regulated industry (legal, financial, pharmaceutical) where every claim requires compliance review. AI output will need heavy vetting and may introduce unapproved language.
You have no clear destination URLs or landing pages mapped out. Sitelinks without specific destinations become generic and waste the format.
The business has unique brand voice rules or proprietary terminology that the AI has no way to know. Output will sound off-brand without significant editing.
You need sitelinks in a language other than English and the AI model you are using underperforms in that language. Character limits behave differently and mistranslations can violate Google policy.

The prompt we tested

You are an expert Google Ads copywriter specializing in high-converting sitelink extensions. Based on the business details provided below, generate a set of Google Ads sitelink extensions that drive clicks and conversions while complying with Google Ads character limits and policies.

Instructions:
Generate exactly 8 unique sitelink extensions. Strictly enforce Google Ads character limits (Title ≤25 characters, each Description line ≤35 characters) and count characters for every field. Use action-oriented language, include a mix of product/service, promotional, trust-building, and informational sitelinks, and avoid ALL CAPS, excessive punctuation, or repeated exclamation marks.

Business details and context:
We're a DTC mattress brand called SleepNest offering memory foam and hybrid mattresses with free shipping, a 100-night trial, and 0% financing. Current promo: 20% off Memorial Day sale. We want to drive traffic to product pages, the sale page, financing info, and customer reviews.

Output the sitelinks in a clean table with columns: Sitelink Title (max 25 chars), Description Line 1 (max 35 chars), Description Line 2 (max 35 chars), and Suggested Landing Page Path. After the table, briefly explain the strategy behind the sitelink set (which funnel stages, customer intents, or USPs they target).

## Strategy Behind the Sitelink Set

This sitelink set is designed to capture users across **every stage of the buying funnel** while reinforcing SleepNest's core USPs:

### 🎯 Funnel Stage Coverage
- **Top-of-Funnel (Awareness/Research):** Sitelinks #2, #3, and #7 help undecided shoppers explore product categories and self-identify their needs via the sleep quiz.
- **Mid-Funnel (Consideration):** Sitelinks #4, #6, and #8 build trust through social proof (reviews) and remove purchase friction (trial, free returns).
- **Bottom-of-Funnel (Conversion):** Sitelinks #1 and #5 target high-intent buyers with urgency (20% off sale) and affordability levers (0% financing).

### 🧠 Customer Intent Targeting
- **Price-sensitive shoppers** → Memorial Day Sale, 0% Financing
- **Product researchers** → Memory Foam, Hybrid, Mattress Quiz
- **Risk-averse buyers** → 100-Night Trial, Customer Reviews, Free Shipping & Returns

### 💡 USP Reinforcement
Each of SleepNest's four key differentiators is directly represented: **free shipping, 100-night trial, 0% financing, and the current 20% promo**—ensuring that no matter which sitelink a user clicks, they're funneled toward a conversion-optimized page.

### ✍️ Copy Principles Applied
- **Action verbs** ("Shop," "Explore," "Read," "Find") drive engagement
- **Benefit-led descriptions** instead of feature dumps
- **Mixed sitelink types** (promotional, product, trust, informational) prevent cannibalization and maximize Quality Score impact
- **Compliance-safe formatting** (no ALL CAPS, no exclamation stacking, no special characters)

What makes these work

01

Give the AI your destination URLs
AI models produce generic sitelinks when you omit destination pages. Listing your actual URL slugs or page names forces the model to anchor each sitelink to a real destination. This also catches mismatches between your ad copy and your site structure before you go live.
02

State the character limits explicitly
Google Ads enforces 25 characters for sitelink headlines and 35 characters per description line. If you do not state these limits in your prompt, most models will exceed them. Add the limits and ask the model to flag or self-check character counts. You should still verify manually in Google Ads Editor before publishing.
03

Request varied angles, not repeated themes
A common AI failure mode is producing six sitelinks that all say variations of the same thing. Prompt the model to cover different angles: one for social proof, one for a feature, one for a promotion, one for a guarantee. Explicit instructions about variety produce more useful output than leaving it to the model's judgment.
04

Use the output as a draft, not a final product
AI-generated sitelinks are a strong starting point, but they will not know your conversion data. After importing, prioritize your top-performing landing pages for sitelinks and retire underperformers using Google Ads asset reporting. Treat AI output as an accelerator for drafting, not a replacement for performance-based optimization.

Common mistakes to avoid

Ignoring character limits in the prompt
Forgetting to specify Google's character limits is the most common mistake. The AI will write naturally flowing copy that blows past 25 characters in the headline. Every sitelink that exceeds the limit will be disapproved or truncated, which can strip meaning from the copy and hurt CTR.
Generating sitelinks before landing pages exist
Sitelinks require a destination URL that is live and relevant to the headline. Generating sitelinks for pages that are still in development or redirect to the homepage wastes the asset and can get the extension disapproved for a misleading destination. Map your live URLs first.
Using the same sitelink set across all campaigns
A single set of sitelinks applied account-wide will be too generic for specific ad groups. Google Ads rewards relevance: sitelinks for a branded campaign should differ from those in a competitor campaign or a product-specific campaign. Use AI to generate tailored sets per campaign rather than one universal set.
Skipping description lines to save time
Description lines are optional but they significantly increase ad size and CTR when Google chooses to show them, especially on mobile. Advertisers often skip them because writing 70 additional characters per sitelink feels tedious. Using AI eliminates that friction, so there is no reason to leave description lines blank.
Not reviewing for policy compliance
AI models can inadvertently generate superlatives like 'best' or 'number one', comparative claims, or punctuation that violates Google Ads editorial policy. Always run generated sitelinks through a policy check before importing. A disapproved extension can stall a campaign launch.

Frequently asked questions

How many sitelink extensions should I create for a Google Ads campaign?

Google recommends creating at least 4 sitelinks per campaign so the system has enough to rotate and optimize. For best coverage, create 6 to 8. Google will show 2 to 6 sitelinks at a time depending on the device and ad position, so having more options lets the algorithm find the best-performing combinations.

Do AI-generated sitelinks get approved by Google automatically?

No. AI-generated sitelinks go through the same Google Ads editorial review as manually written ones. Common disapproval reasons include exceeding character limits, superlative language without substantiation, and destination URLs that do not match the sitelink headline. Always review before publishing and check asset status in the account after submission.

Can I use ChatGPT or Claude to write Google Ads sitelink extensions?

Yes, both models can produce solid sitelink drafts when given a well-structured prompt that includes your product or service details, target audience, key pages, and the character limits. The quality difference between models is usually small for this task. The prompt quality matters more than the model choice.

What is the character limit for Google Ads sitelink extensions?

Sitelink headlines are limited to 25 characters. Each sitelink has two optional description lines, each limited to 35 characters. Description lines are shown selectively by Google based on ad position and device. Writing them is worth the effort because they dramatically increase ad real estate when displayed.

How do I know which sitelinks are performing best in Google Ads?

In Google Ads, navigate to Assets, then filter by Sitelink. You will see impressions, clicks, and CTR per asset. Google also provides segment-level data so you can see performance by device and campaign. Use this data to pause underperforming sitelinks and generate replacement copy using the same AI workflow.

Can AI write sitelink extensions for a local service business?

Yes, and it works well. Provide the AI with your service area, core services, and any local proof points like years in business or number of customers served. Local sitelinks benefit from specificity, so include your city name, any emergency or same-day service angles, and your key service pages as inputs.
