Trustpilot to Google Sheets, ad angles ready to use

Lisa Granqvist Partner Workflow Automation Expert

Reading competitor reviews is useful. Copying them into a spreadsheet, sorting by rating, and trying to “find patterns” while your campaign clock is ticking is the part that breaks you.

This Trustpilot ad angles workflow hits performance marketers first, but small business owners and agency leads feel it too. You get a clean Google Sheet of reviews plus three ready-to-test ad copy variations built from real 1–2 star pain points.

Below, you’ll see exactly what this automation does, what it replaces, and how to adapt it to your niche without turning it into a science project.

n8n Workflow Template: Trustpilot to Google Sheets, ad angles ready to use

The Problem: Review Research Is Slow, Messy, and Easy to Get Wrong

If you’ve ever built ad angles from competitor reviews, you know the routine. You open Trustpilot, scroll forever, copy a few lines, paste them into a doc, then try to remember which review came from which month. Next comes the “analysis,” which usually means reading 50 complaints and guessing what the real pattern is. Then you write ads from memory. It’s not just time-consuming. It’s inconsistent, and the worst part is you can’t prove why an angle should work because your source material is scattered.

The friction compounds. And once you need to do this weekly (or across multiple competitors), it turns into a recurring tax on your marketing team.

  • Copy-pasting reviews into a spreadsheet takes about 1–2 hours per competitor if you want enough data to trust it.
  • You end up mixing timeframes, so the “trend” you spotted is really just last week’s noise.
  • Manual filtering for 1–2 star reviews is tedious, which means it often gets skipped.
  • Ad copy drafts get watered down because the research isn’t organized and nobody wants to reread 100 reviews.

The Solution: Trustpilot → Sheets → OpenAI Drafts You Can Test

This workflow turns competitor review scraping into a repeatable system. You start by submitting a simple form with a competitor’s Trustpilot URL and a timeframe (like 30 days or 12 months). n8n sends that request to Bright Data’s dataset API, then automatically waits and polls until the snapshot is ready. Once the data is available, the workflow retrieves all reviews and appends them into a structured Google Sheet so you can sort, filter, and share it like any other research doc. Then it narrows the focus to 1–2 star reviews, compiles the complaint text, and asks OpenAI (GPT-4o-mini) to summarize the real pain points and draft three ad copy variations based on what people actually hate.

The workflow starts with a form submission in n8n. From there, Bright Data handles the Trustpilot scraping while n8n waits and checks status in the background. Finally, Google Sheets stores the raw material and OpenAI turns it into a summary plus ad angles, which are emailed to your team.

What You Get: Automation vs. Results

Example: What This Looks Like

Say you want to research 3 competitors before writing a new Facebook campaign. Manually, you might spend about 2 hours per competitor: 1 hour collecting reviews, 30 minutes sorting and tagging, and another 30 minutes pulling themes into a brief (so roughly 6 hours total). With this workflow, you submit three form runs that take about 5 minutes each, then wait for Bright Data to return the snapshot in the background. In under an hour of hands-off time, you have the Sheet filled, a summary of recurring complaints, and three ad copy variations emailed to your team.

What You’ll Need

  • n8n instance (try n8n Cloud free)
  • Self-hosting option if you prefer (Hostinger works well)
  • Google Sheets to store reviews and keep a swipe file.
  • Bright Data to scrape Trustpilot reviews reliably.
  • OpenAI API key (get it from your OpenAI dashboard).

Skill level: Intermediate. You’ll connect credentials, paste a Sheet ID, and tweak a prompt, but you won’t be writing code.

How It Works

A form submission kicks it off. You enter the competitor’s Trustpilot URL and pick a timeframe (30 days through 12 months). That input becomes the “job request” used for scraping.

Bright Data scrapes, while n8n waits and checks status. The workflow triggers a dataset snapshot via HTTP request, pauses using a Wait node, then polls Bright Data until the snapshot is ready. No tab-switching. No manual refresh.

Reviews are stored and cleaned up in Google Sheets. Once results come back, n8n appends them to your template sheet, then filters down to 1–2 star reviews and compiles the text into something an LLM can actually work with.

OpenAI generates the useful part. GPT-4o-mini summarizes common negative feedback and drafts three ad copy variations. n8n then emails the summary and drafts via Gmail so the team can move straight into testing.

You can easily modify the timeframe options or the prompt tone based on your needs. See the full implementation guide below for customization options.

Step-by-Step Implementation Guide

Step 1: Configure the Form Trigger

This workflow starts when a user submits a form with a Trustpilot URL and time frame.

  1. Add and open Form Intake Trigger.
  2. Set Form Title to Please Paste The URL of Your Trustpilot competitor.
  3. In Form Fields, confirm the URL field label is Competitor TRUSTPILOT URL (include https://www.trsutpilot.com/review/ and the dropdown options include Last 30 days, Last 3 months, Last 6 months, Last 12 months.

Keep the field labels exactly as shown because downstream expressions reference them.

Step 2: Connect Bright Data API Requests

These nodes trigger the Bright Data scrape and poll for completion before downloading results.

  1. Open Trigger Bright Data Job and set URL to https://api.brightdata.com/datasets/v3/trigger with Method POST.
  2. Set JSON Body to =[ { "url": "{{ $json['Competitor TRUSTPILOT URL (include https://www.trsutpilot.com/review/'] }}", "date_posted": "{{ $json['Please select the time frame of reviews you\'d like. If it\'s a big brand go with 30 days'] }}" } ].
  3. In Query Parameters, set dataset_id to [YOUR_ID] and include_errors to true.
  4. In Header Parameters, set Authorization to Bearer [CONFIGURE_YOUR_API_KEY].
  5. Open Delay for Data Poll and set Unit to minutes and Amount to 2.
  6. Open Fetch Snapshot Status and set URL to =https://api.brightdata.com/datasets/v3/progress/{{ $('Trigger Bright Data Job').item.json.snapshot_id }}, and keep the Authorization header as Bearer [CONFIGURE_YOUR_API_KEY].
  7. In Snapshot Status Check, confirm the condition uses ={{ $json.status }} equals running.
  8. Open Retrieve Bright Data Results and set URL to =https://api.brightdata.com/datasets/v3/snapshot/{{ $('Trigger Bright Data Job').item.json.snapshot_id }} with query format set to json and the same Authorization header.

⚠️ Common Pitfall: Bright Data requests will fail if [YOUR_ID] and [CONFIGURE_YOUR_API_KEY] are not replaced with valid values.

Step 3: Connect Google Sheets

Store retrieved reviews in Google Sheets for recordkeeping and downstream filtering.

  1. Open Append Reviews to Sheet and confirm Operation is set to append.
  2. Set Document to [YOUR_ID] and Sheet to gid=0.
  3. Credential Required: Connect your googleSheetsOAuth2Api credentials.

Step 4: Filter and Aggregate Low Ratings

This stage keeps only 1–2 star reviews and compiles review text for summarization.

  1. Open Filter Low Ratings and ensure conditions use ={{ $json.review_rating }} equals 1 OR 2.
  2. Open Compile Review Text and set Fields To Aggregate to aggregate review_content into Aggregated_reviews.

Step 5: Set Up the AI Summary

Use an LLM to generate insights and ad copy from the aggregated complaints.

  1. Open LLM Summary Builder and set Prompt Type to define.
  2. Set Text to =Read the following bad reviews, these are reviews of our competitors: {{ $json.Aggregated_reviews }} --- After reading them, summarize their weakest points. Don't mention the competitor name. Write 3 different ads copy for our Facebook ads campaign, addressing these concerns.
  3. Open OpenAI Chat Engine and select the model gpt-4o-mini.
  4. Credential Required: Connect your openAiApi credentials in OpenAI Chat Engine, which powers LLM Summary Builder.

If the summaries look too short, increase the context by aggregating more reviews in Compile Review Text.

Step 6: Configure the Email Output

Send the summary and full complaint breakdown to your inbox.

  1. Open Email Marketing Summary and set Send To to [YOUR_EMAIL].
  2. Set Subject to =Summary of Complaints of competitor: {{ $('Form Intake Trigger').item.json['Competitor TRUSTPILOT URL (include https://www.trsutpilot.com/review/'] }}.
  3. Set Message to =Based on the following Trustpilot page: {{ $('Form Intake Trigger').item.json['Competitor TRUSTPILOT URL (include https://www.trsutpilot.com/review/'] }} Here is a summary of recent complaints including ideas for ad copy: {{ $json.text }} ----------------------------- I'm also attaching a break down of all recent complaints {{ $('Compile Review Text').item.json.Aggregated_reviews }} .
  4. Credential Required: Connect your gmailOAuth2 credentials.

Step 7: Test & Activate

Validate the workflow end-to-end before turning it on.

  1. Click Execute Workflow, then submit the Form Intake Trigger form with a valid Trustpilot URL.
  2. Confirm Snapshot Status Check routes back to Delay for Data Poll when status is running, and to Retrieve Bright Data Results when it completes.
  3. Verify new rows appear in Google Sheets from Append Reviews to Sheet and only 1–2 star reviews continue through Filter Low Ratings.
  4. Check your inbox for the email from Email Marketing Summary containing a summary and the aggregated complaints.
  5. Once successful, toggle the workflow to Active for production use.

Common Gotchas

  • Bright Data credentials can expire or need specific permissions. If things break, check your Bright Data dataset token and allowed headers first.
  • If you’re using Wait nodes or external rendering, processing times vary. Bump up the wait duration if downstream nodes fail on empty responses.
  • Default prompts in AI nodes are generic. Add your brand voice early or you’ll be editing outputs forever.

Frequently Asked Questions

How long does it take to set up this Trustpilot ad angles automation?

About 30 minutes if your accounts are already set up.

Do I need coding skills to automate Trustpilot ad angles?

No. You’ll connect credentials and paste in your Google Sheet details. The rest is configuration and light prompt editing.

Is n8n free to use for this Trustpilot ad angles workflow?

Yes. n8n has a free self-hosted option and a free trial on n8n Cloud. Cloud plans start at $20/month for higher volume. You’ll also need to factor in Bright Data usage and OpenAI API costs (usually a few cents per run for GPT-4o-mini).

Where can I host n8n to run this automation?

Two options: n8n Cloud (managed, easiest setup) or self-hosting on a VPS. For self-hosting, Hostinger VPS is affordable and handles n8n well. Self-hosting gives you unlimited executions but requires basic server management.

Can I customize this Trustpilot ad angles workflow for my niche and brand voice?

Yes, and you should. Update the prompt inside the LLM Summary Builder so it uses your offer language, compliance rules, and tone (for example, “premium,” “direct-response,” or “clinical”). You can also change the filter logic to include 3-star reviews if your category has softer complaints, then adjust the OpenAI Chat Engine prompt to output different formats like hooks-only, headline packs, or UGC-style scripts.

Why is my Bright Data connection failing in this Trustpilot ad angles workflow?

Usually it’s an expired or incorrect authorization header. Regenerate your Bright Data token, update it in the HTTP Request nodes, and confirm the dataset API endpoint matches the dataset you’re calling. If it still fails, check snapshot status responses for errors, and make sure your Bright Data plan allows the dataset you’re trying to use.

How many reviews can this Trustpilot ad angles automation handle?

A lot, as long as your Bright Data plan and your n8n execution limits can handle it.

Is this Trustpilot ad angles automation better than using Zapier or Make?

For this workflow, n8n is a better fit because it can handle polling loops, branching logic, and data shaping without turning into a fragile chain of zaps. Self-hosting is also a big deal if you plan to run this often and don’t want every run counted as a premium task. Zapier or Make can still work if you simplify the job (for example, no polling, fewer transformation steps), but you’ll usually hit limits faster. Frankly, the “scrape + wait + recheck” pattern is where lighter tools get annoying. Talk to an automation expert if you’re not sure which fits.

Once this is running, competitor review research stops being a “someday” task and becomes a button you press. The workflow handles the repetitive stuff. You handle the testing.
