This post is part of the GenAI Series.
Back-to-back GenAI-related posts, but I could not resist writing this post instead of a trading-related one.
A few days ago, I built a small tool that lets you input an Amazon ASIN and instantly generate marketing copy, including Facebook ads, Amazon A+ content, and SEO product descriptions by using Gemini. The frontend is built with Bootstrap + jQuery, and the backend runs on Python Flask. While this was originally aimed at Amazon sellers, it turned out to be a fun exercise in prompt engineering, tool chaining, and turning structured product data into persuasive, persona-targeted content.
If you are in a hurry, then watch the video demo below; otherwise, read on.
The very first goal was to fetch real-time product information from the Amazon website. Scraping Amazon is not an easy task, so there must be an easier way to do it. Thankfully, ScraperAPI offers an easy-to-use API that makes life easier. ScraperAPI provides something they call Structured Data Endpoints or SDE, which actually takes all the burden of worrying about IP bans, network throttling, bot detection, and dynamic HTML. You access the relevant endpoint and fetch information either in JSON or Markdown format. They also provide SDE endpoints for Google products like Maps, Shopping, Walmart, and eBay.
Alright, so the goal is to use ScraperAPI’s SDE endpoint to fetch the product data like title and description, etc., and pass this on to Gemini to get different types of ad copy.
Development
Since this is a Flask app, you should have Flask installed. You will also need the Google GenAI library installed. You will also need an API key that you can create here. The ScraperAPI SDE endpoint for Amazon returns the following JSON payload against the product’s ASIN:

"review": "I go through outdoor speakers every few years. The last set (Monoprice) lasted 5-6 years(?), but I suspect the woofer surrounds rotted out a couple of years ago; they were 50% completely missing! They never sounded very good either. The all-good reviews on the Polk Atrium 5 looked like they could be worth the higher cost than I usually pay. So I snapped up a \"Used - Mint Condition\" pair that actually looked unopened.Bingo! The bass is very good for a 5\" woofer, with reasonably extended lows. Very clear sound overall. Time will tell if they can handle our hot dry So. California sun better than the rest. \n \nRead more",

"review": "I installed these on my pool lanai to replace some old speakers I had. I am blown away by them. From my pool I have perfect stereo imaging. What that means, is that not only does it sound great, but it does not have to be loud to hear all the details of the music. My neighbors definitely apricate that. I'm a HiFi geek and these absolutely satisfy my audiophile needs. I had thought about going with the larger version but these are perfect for my needs. These are powered by the Zone Two of my Onkyo RZ50 (I highly recommend as well) which is 120w per channel. That power definitely helps, but I'm sure these will sound great off of any decent amp. If you are looking for a good quality outdoor speaker I guarantee you will be more then happy with these.\n \nRead more",

Crisp highs and surprisingly low lows. They are a little larger but I mounted them on the ceiling and they just blend in well. Pointed down at 45° they fill the area and don't sound like they're above. Time will tell about durability, but sound quality is very good out of the box...and that's from a very picky audiophile. Pushing these with a nice Sony 600w receiver...which is overkill...but there's no substitute for power and they handle half volume with no distortion with a rich full sound.\n \nRead more",

For the sake of this demo, I am going to pass the entire JSON.
Alright, so there are two prompts involved in it: the first takes the product data and figures out the target audience, and the second one generates the actual ad copy.
Let’s do a bit of prompt engineering. We will be writing the first prompt that takes product JSON data and returns a list of the target audience. If you do not know about prompt engineering, then I would recommend reading my post here.
Target Audience Prompt
Below is the system prompt that suggests the target audience for the product:
You are a marketing strategist. Given the following product JSON data, analyze the product specifications, features, design elements, tone of customer reviews, and potential emotional or practical benefits. Based on that, return a JSON array of recommended target audiences who are most likely to resonate with this product. Focus on demographics, personas, or niche interests (e.g., "Christian moms", "teen girls", "skincare lovers", "makeup professionals", etc.). Only output the result as a clean JSON array like below: [ "Christian moms", "Teen girls interested in makeup", "Women who travel frequently", "Buyers looking for faith-inspired gifts", "People with vision impairments needing magnification" ] Do not include any explanation, notes, markdown, or text outside the JSON.
The relevant Flask endpoint is:
@app.route('/get_audiences', methods=['POST'])
def get_audiences():
asin = request.form.get('asin')
product_json = json.dumps(get_product(asin), separators=(',', ':'))
# print(product_json)
prompt_audience_file = "prompt_audience.txt"
prompt_audience = None
with open(prompt_audience_file, encoding="utf8") as f:
prompt_audience = f.read()
# Replace the placeholder with the actual product json
prompt_audience = prompt_audience.replace("{product_json}", product_json)
# print(prompt_audience)
response = client.models.generate_content(
model="gemini-2.5-flash",
config=types.GenerateContentConfig
(
system_instruction=prompt_audience,
response_mime_type="application/json",
),
contents=product_json
)
# Mock suggested audiences
audience_list = json.loads(response.text)
return jsonify({
"audiences": audience_list,
"product": product_json
})
When I execute this endpoint it returns:
{
"audiences": [
"Music lovers who enjoy listening to audio in the shower",
"Tech enthusiasts and early adopters interested in innovative gadgets",
"Environmentally conscious consumers seeking products made from recycled materials",
"Individuals looking for convenient, low-maintenance smart home or bathroom accessories",

When I heard about this I bought it right away. Easy installation, sounds very good, but when the speaker gets wet there is sometimes distortion. I think this is more of an early-adopter product. You should know that it is really big, make sure you take a look at the measurements. My wife was like what the hell is that thing on the showerhead?! But it works so well, it charges the battery seamlessly whenever the water is running, we have experienced no change in water pressure. The speaker comes off so you can place it wherever you want.

Something I didn't think of before until I got the warranty replacement in the mail yesterday, my original order was apparently tampered with or a reconditioned unit. It had another sticker over the original one sealing the box. Well, my warranty replacement did too. I paid for a new unit, and received a reconditioned one. I will say they stood by the warranty and replied to me via this review, not my email to them. Installed the unit today, no leaks.---------We love the idea of this speaker. This is our second one. We remodeled our bathroom and had to get a black one instead of the first silver one we bought. At 6 months, it developed a leak inside the unit. At first, I thought it was at one of the connections, so I took it down, reapplied Teflon tape, and reinstalled. Then the leak got worse. You can see how bad it is now on the video. This unit was installed 6 months ago.It wouldn't fully charge from the water flow either, so every month or so, if have to plug the speaker into the wall to fully charge. The turbine may have helped maintain the battery but it would slowly go down over the course of the month.If the manufacturer stands by their warranty, I'll update this review.

Shower has to be at full blast to charge. Bluetooth connection gets lost every once in a while (in the middle of the shower session) and the randomly reconnects. Good for a first try but not really ready for prime time. Also, it's HUUUGE so if you have a removable shower head then this has to connect to the wall pipe and you might not be able to hang your shower head anymore so get a separate shower head holder that you can stick beside it.\\n \\nRead more\",\"review_url\":\"https://www.amazon.com/gp/customer-reviews/R32R0C1ZODK8AM/ref=cm_cr_dp_d_rvw_ttl?ie=UTF8&ASIN=B09R93MDJX\",\"total_found_helpful\":2,\"images\":[],\"variation\":{}},{\"stars\":5,\"date\":\"Reviewed in the United States on January 28, 2023\",\"verified_purchase\":false,\"manufacturer_replied\":false,\"username\":\"GreenGreen\",\"user_url\":\"https://www.amazon.com/gp/profile/amzn1.account.AEJRQZDLGQRPACZSI43VC7NC76TA/ref=cm_cr_dp_d_gw_tr?ie=UTF8\",\"title\":\"5.0 out of 5 stars\\n\\n\\n\\n\\n\\n\\n\\n \\n \\n It\\u2019s expensive but just buy it\",\"review\":\"VERY easy to install (literally takes a few seconds).

Ad Copy Prompt
Below is the system prompt that generates the Ad copy for the product:
### PERSONA
The target audience for this marketing copy is: {persona}
### CORE LOGIC
You are a skilled AI marketing copywriter. Given a detailed JSON object describing a product (including specs, reviews, and attributes), analyze the product features, benefits, and sentiment.
Understand the product from a marketing perspective. Identify what would appeal most to the specified persona based on the available data. Focus on emotional benefits, practical utility, and standout features such as design, lighting, symbolism, or ease of use.
### OUTPUT FORMAT
Generate only the final ad copy in **Markdown format**, with no title, no labels, no preface, and no suffix. Do not include anything like "Here is the copy" or "Targeted at...".
The style should include:
- A bold, catchy hook
- A short intro paragraph
- 2–3 benefit-based bullet points
- A strong call to action at the end
All content must be tailored to the persona and grounded in the product details below.
And the relevant Flask endpoint:
@app.route('/generate_copy', methods=['POST'])
def generate_copy():
persona = request.form.get('persona')
output_type = request.form.get('output_type')
product_json = json.loads(request.form.get('product_json'))
prompt_ads_file = "prompt_ad_copy.txt"
prompt_ads = None
with open(prompt_ads_file, encoding="utf8") as f:
prompt_ads = f.read()
prompt_ads = prompt_ads.replace("{persona}", persona)
response = client.models.generate_content(
model="gemini-2.5-flash",
config=types.GenerateContentConfig
(
system_instruction=prompt_ads,
),
contents=product_json
)
copy = response.text.strip()
return jsonify({"copy": copy})
When you execute this endpoint, it returns:
{
"copy": "**Never Let the Music Stop: Your Shower's New Powerhouse Has Arrived!**\n\nTransform your daily routine into a concert with the Ampere Shower Power.

Conclusion
In the end, this project was a fun blend of practical AI application and lightweight backend development. It’s always exciting to see how a few smart prompts and simple tools like Flask and Gemini can come together to solve a real problem for sellers and marketers. A big part of what made this work smoothly was ScraperAPI, whose structured Amazon API made it easy to access real-time product data without worrying about IP bans or scraping hurdles. Whether you’re an Amazon seller looking to save time or a developer exploring GenAI workflows, this kind of tool shows just how accessible and powerful AI-driven automation has become.
Oh, and just so you know, I’ve been using their service whenever I need to build scalable scrapers or pull data from complex sites, especially those protected by captchas or things like Cloudflare. It’s been super reliable and saves a ton of time. If you’re interested, you can sign up using my referral link or use the promo code adnan10 to get 10% off. And if the discount doesn’t show up for some reason, just drop me an email through my site and I’ll help you out. Like always, the code is available on GitHub
