How we helped Writesonic achieve a 350% revenue growth with paid media.
About Writesonic
Writesonic is an AI-powered writing tool that helps businesses generate high-quality content in a matter of seconds. Its advanced algorithms are capable of creating various types of content such as blogs, ads, emails, website copies, product descriptions, and more.
Writesonic and its other tools like ChatSonic (AI chatbot) are ideal for businesses of all sizes — ranging from startups to large enterprises.
The challenge
Writesonic raised a total of $2.6M in funding over 2 rounds and wanted to scale faster with paid acquisition.
Their primary goal was to acquire more paying customers through various channels while maintaining a controlled CPA for both — their primary AI writing tool and ChatSonic (the ChatGPT alternative).
As paid marketing experts, Hey Digital knew how to help Writesonic attract new users, increase brand awareness, and boost revenue.

Our approach
After thorough research, Hey Digital identified Facebook, TikTok, and Google Ads as the most promising platforms to reach their target audience.
The teams agreed to promote a free trial for Writesonic and ChatSonic with search ads and stunning ad creatives. To convert the ad clicks to signups, we launched conversion-focused landing pages.
Further, we used retargeting campaigns for converting people who had already shown interest in their tools.
All of this proved to be a game-changer and led to a 131% increase in signups — which is a big win! 🎉
Here’s a quick breakdown of everything else we did.
Channel Experiments
Apart from the marketing channels already mentioned, we conducted experiments with additional channels like YouTube and Performance Max.
The results were so impressive that we included Performance Max as one of their primary prospecting channels.

Ad Creative Testing
We came up with different ad angles to test what resonates the most with the audience. We also used the voice of customer data to guide the ad copies.
Additionally, we launched different types of creatives — statics, carousels, GIFs, and videos — to test their effectiveness and re-launch the most successful ones.

Custom Landing pages
At Hey Digital, we believe that ads sell the click, and landing pages sell the offer.
We created on-brand landing pages that combined the power of copywriting, UX, and psychology to drive more conversions.
