Catchy, compelling ad copy is crucial for running successful online advertising campaigns. However, coming up with creative headlines and descriptions that capture attention and drive clicks can be challenging and time-consuming. This is where ad copy generators come in handy.
Powered by artificial intelligence (AI) and natural language processing, these tools can automatically generate optimized ad copy for platforms like Google Ads, Facebook Ads, and more in just minutes.
In this comprehensive 4100+ word guide, we’ll compare the top 10 ad copy generators on the market and provide tips for using them effectively to boost your PPC and social campaigns.
What is Ad Copy and Why Does it Matter?
Ad copy refers to the textual content in a paid ad, consisting primarily of the headline and description. This copy plays a pivotal role in determining the ad‘s clickthrough and conversion rates.
The headline hooks readers, while the description convinces them to click by highlighting the offer‘s key benefits and value proposition. Compelling ad copy essentially “sells” to the target audience why they should care.
With platforms like Google Ads and Facebook limiting texts to just 25-30 words on average per ad, every single word counts in making an impact.
Well-optimized ad copy results in more qualified traffic, lower cost-per-click, and higher ROI from advertising spend.
Ad Copy Performance Benchmarks
According to Wordstream research, top-performing Google Ads across industries tend to achieve:
- Headline CTR of 5-15% (Advertising industry is highest at 11-15%)
- Description CTR of 2-4% (B2C services industry is highest at 3-5%)
- Landing page conversion rates of 2-12%, depending greatly on offer, niche etc.
Meanwhile, top-performing Facebook ad CTR averages 0.9-2%, significantly lower than search ads due to the more interruptive nature.
Benefits of Using Ad Copy Generators
While human copywriters create high-performing ads, ad copy generators offer the following advantages:
1. Faster ideation – Most tools can churn out tons of catchy headlines and description options in just seconds. This allows testing dozens of different copy variations.
2. Leverages AI writing – The algorithms study millions of high-performing ads to identify patterns in effective copy. Some also utilize natural language processing to generate new text matching your inputs and tone parameters.
3. Saves time – You skip the effort of drafting new copy ideas from scratch every time. Relying fully on tools, advertisers have been able to scale running 1000s of ad variations.
4. Provides templates – Many tools feature preset templates for different campaign goals, products, and industries to accelerate copy fitting the scenario. Pre-defined frames make it easy for anyone to produce decent titles and descriptions.
5. Easy split testing – Testing different auto-generated copies is simpler than continually asking a copywriter for new options. The top tools integrate directly with platforms like Google Ads and Meta Ads Manager to quickly run A/B experiments.
6. Scalable – You aren‘t limited by the bandwidth of an in-house copywriter, especially for large accounts with hundreds of ads. High performing brands have leveraged copy generators to run upwards of 20,000+ active ad variations.
Next, let‘s compare the top ad copy generators…
Evaluating Ad Copy Generators
Not All Tools Are Created Equal
When it comes to automatically generating advertising copy, companies utilize very different underlying technologies ranging from basic templating all the way to advanced generative AI.
Before diving into the top tools, it helps to level-set on a few key machine learning concepts powering modern solutions:
Templates
The most basic copy generators rely on pre-defined Mad Libs-style templates and formulas with blanks to fill in. For example:
"{Your product} eliminates {customer problem} unlike any other solution. Learn how it drives {main benefit}."
While fast, this approach lacks originality.
Pre-Trained Models
More advanced tools rely on machine learning models trained on hundreds of existing high-performing ad copies. These models identify patterns in effective copy and attempt to recreate new samples following proven templates and wording formulas.
Generative AI
The cutting-edge relies on large language models like GPT-3 which can generate completely new long form content as if written by a human, while aligning to parameters like your product specs, tone guidelines etc. This delivers great flexibility and variability.

Key Tips for Using Ad Copy Generators
Follow these tips and best practices to maximize the performance of auto-generated ad copies:
Provide Very Detailed Prompts
The quality of output depends heavily on providing clear instructions to the AI assistant on critical elements like:
- Key customer problem/pain points
- Product name and key unique benefits
- Target audience specs like age, gender, location etc
- Ideal tone parameters like friendly, urgent, casual
- Must-have power words or phrases
Generate At Least 7-10 Variations
Don‘t just take the very first headline and description output. Ask for a handful of options upfront to compare.
Programmatically it‘s cheap to spin out additional variations, allowing you to only pick the very best performer instead of getting stuck having to make mediocre copy work.
Specify Different Tones
Most tools allow tailoring output tone on parameters like:
- Urgent
- Friendly
- Formal
- Witty
- Direct
- Question-Based
For example, running the same offer specs through the generator but toggling between an urgent tone vs. friendly tone can yield very different prescribing results.
Examine all the options to identify what best resonates with your audience.
Review Platform Guidelines
Double check any auto-generated copy against the latest platform guidelines before publishing ads. Especially take note of character limits which tools can sometimes exceed unless size parameters are set properly.
Additionally, occasionally tools can recommend headings or words no longer allowed by platforms. Verify policy compliance before hitting publish.
Set Up A/B Testing
Rather than guess which option might perform best, set up live ad experiments across at least a few of the high-potential variants.
Monitor their performance for 2-3 weeks minimum before declaring winners that will move into active rotation. The small upfront time investment pays back exponentially.
Perfect Lines With Human Polishing
Even AI-generated copy isn‘t perfect. While tools handle the heavy lifting around ideation and initial drafting, still expect to spend a few minutes reviewing computer outputs.
Look for minor rough patches that need polish to have the finals ads shine. Whether slightly awkward phrases, redundant words, or boring superlatives, clean up the machine‘s rougher edges.
Then you capitalize on technology scale meets the subjective human touch required for the highest conversions.
Limitations to Understand
While ad copy generators showcase impressive AI advancements, some key creative limitations still separate the very best human copywriting vs. solely relying on tools:
Lacks Complex Emotional Appeal
today‘s algorithms struggle infusing deeper emotions like nostalgia, humor, FOMO etc. that connect on a more intrinsic human level. The technology predominantly takes a logical features/benefits-focused approach.
Thus human-written copies better tap into psychological drivers behind decision making. But this gap is actively being worked on through emotional intelligence research.
Sometimes Makes Logical Leaps or Unclear Transitions
Without full contextual understanding of products, tool outputs can have disjointed flow. For example transitions between sentences may lack bridges tying points together.
Humans maintain full conceptual understanding to smoothly guide readers from start to finish.
Misses Bigger Picture Optimization
Tools focus on executional copy quality. But higher level strategy like identifying the right target segment, offer crafting, campaign objectives etc. still necessitate human oversight.
Algorithms can‘t holistically recommend optimizations for the full business or campaign results. Human intuition picks up on key trends and insights to evolve entire strategies.
Platform Guidelines Rapidly Change
New policies might imposed by channels like Google that require ads to adapt accordingly. Continual monitoring and evolution is needed.
Thus savvy marketers will use ad generators as AI assistants rather than complete replacements for thoughtful human copy oversight and strategy.
The future blend likely involves marketers providing the high-level creative direction and optimization while tools generate the raw drafts fitting those ever-evolving strategies.
Level Up Your Advertising Today
Cutting-edge ad copy generators leverage the exponential power of artificial intelligence to deliver strong performing headlines and descriptions with minimal effort.
Yet human creativity, emotions, strategy and oversight still play a pivotal role in excelling across channels like Google Ads, Facebook and more.

Put these expert tips into practice and build a framework to efficiently scale results-driving ad copy powered by the move advanced AI available today.
