SerpAPI to Google Chat, catch PR risks early
Your brand gets mentioned online every day. The problem is you usually find out late, after a Reddit thread has 200 comments or a review post is already ranking on Google.
This is where SerpAPI PR alerts help most. PR managers feel the heat first, but marketing leads and agency teams managing client reputation deal with the same “where do I even look?” chaos. This workflow spots risky mentions early, then pings the right place with a clear next step.
You’ll see how it scans public platforms hourly, uses AI to score risk, and only alerts you when it actually matters (with an Asana task created automatically).

The Problem: Brand mentions spread faster than your monitoring
Manual reputation monitoring sounds simple until you actually do it. You check Reddit, then Glassdoor, then review sites, then Google results, then you repeat tomorrow because the “one bad post” you ignored now has screenshots on X. The real cost isn’t just time. It’s context switching, missed signals, and that uneasy feeling that you’re always reacting instead of staying ahead. And frankly, most teams don’t have a clean way to decide what’s urgent versus what’s just noise.
It adds up fast. Here’s where it breaks down in real life.
- Someone has to remember to look, which means the worst days are the days you miss it.
- Even when you catch a mention, it’s hard to judge urgency without reading a whole thread.
- Alerts from basic tools get ignored because they flag everything, including harmless chatter.
- No owner gets assigned, so “we should respond” turns into “did anyone respond?”
The Solution: Hourly AI triage that alerts and assigns owners
This n8n workflow runs on an hourly schedule and searches for your brand (or keywords you define) across public sources using SerpAPI. Instead of dumping raw search results on you, it processes the findings into a cleaner set of “mentions” that an AI agent can evaluate. The AI then classifies sentiment and crisis risk, so you get a practical answer like “low risk complaint” or “high risk escalation,” not a wall of links. If the risk crosses your threshold, the workflow posts an alert directly into Google Chat and creates an urgent Asana task so someone is clearly accountable. There’s also normalization and fail-safe handling so messy AI outputs don’t silently break the automation.
The workflow starts with Cron, which means it’s always-on without someone remembering. SerpAPI pulls the latest mentions, the AI risk evaluator scores them, and an If filter keeps only high-risk results. From there, Google Chat gets the heads-up and Asana gets the follow-up.

Example: What This Looks Like
Say you check three places manually each day (Reddit, reviews, and “brand name + complaint” on Google). Even at 10 minutes per check, that’s about 30 minutes a day, or roughly 3 hours a week, and it still depends on you remembering. With this workflow, the “work” is basically setting it once and reviewing only the high-risk alerts that land in Google Chat. Most weeks, that’s a handful of messages plus a few Asana tasks, not hours of browsing and second-guessing.
What You’ll Need
- n8n instance (try n8n Cloud free)
- Self-hosting option if you prefer (Hostinger works well)
- SerpAPI for public search results and mentions.
- Google Chat to deliver urgent alerts to your team.
- Asana to create priority tasks for follow-up.
- Azure OpenAI credentials (get them from the Azure Portal in your OpenAI resource).
Skill level: Intermediate. You’ll connect a few accounts, add credentials, and tweak risk thresholds or keywords.

How It Works
Hourly monitoring kicks things off. The workflow runs on a Cron schedule, so it checks for new mentions without relying on anyone’s calendar reminders.
Search results get pulled and cleaned up. SerpAPI retrieves fresh results from sources like Reddit and review sites, then a processing step extracts the pieces you actually need for evaluation and alerting.
AI evaluates risk and urgency. An AI agent paired with an Azure OpenAI chat model scores sentiment and crisis potential, then normalizes the output into a predictable format so downstream steps don’t break.
Only high-risk items get escalated. An If filter keeps the noise down, then Google Chat receives the alert and Asana gets an urgent task to make ownership explicit.
You can easily modify the keywords being monitored to focus on product names, executive names, or competitor comparisons based on your needs. See the full implementation guide below for customization options.
Step-by-Step Implementation Guide
Step 1: Configure the Cron Trigger
Set the workflow to run on an hourly schedule using the built-in trigger node.
- Add the Hourly Schedule Trigger node to your canvas.
- In Trigger Times, set Mode to
everyHour. - Connect Hourly Schedule Trigger to Retrieve Brand Mentions.
Step 2: Connect SerpAPI Search for Brand Mentions
Pull AI-mode search results for brand mentions from SerpAPI.
- Add Retrieve Brand Mentions and set Operation to
google_ai_mode. - Set Query to
site:reddit.com "[Your Brand Name]" reviews. - Credential Required: Connect your serpApi credentials.
- Connect Retrieve Brand Mentions to Process Search Insights.
[Your Brand Name] will produce irrelevant results.Step 3: Process Results and Configure the AI Risk Analyzer
Normalize the search output and evaluate each insight using an AI agent.
- Add Process Search Insights and keep the provided JavaScript Code to split insights into individual items.
- Add Reputation Risk Evaluator and set Text to the prompt using the expression
{{ JSON.stringify($json, null, 2) }}within the provided template. - Connect Process Search Insights to Reputation Risk Evaluator.
- Add Azure AI Chat Model and set Model to
gpt-4o-mini. - Credential Required: Connect your azureOpenAiApi credentials in Azure AI Chat Model.
Note: Azure AI Chat Model is connected as the language model for Reputation Risk Evaluator—ensure credentials are added to Azure AI Chat Model, not the agent node.
Step 4: Clean AI Output and Filter High-Risk Findings
Parse the AI JSON output and only pass through high-risk items.
- Add Normalize AI Results and keep the provided JavaScript Code to parse
item.json.outputinto clean fields. - Connect Reputation Risk Evaluator to Normalize AI Results.
- Add Filter High Risk Findings and set the condition to Value 1
={{$json["risk_level"]}}and Value 2High. - Connect Normalize AI Results to Filter High Risk Findings.
Step 5: Configure Alerts and Task Creation
Send urgent notifications and create tasks when a high-risk finding is detected.
- Add Post Google Chat Alert and set Space ID to
={{ $json.space }}. - Credential Required: Connect your googleChatOAuth2Api credentials.
- Add Generate Asana Urgent Task and set Name to
🚨 Social Crisis Detected — Immediate Action Required. - Set Workspace to
[YOUR_ID]and keep Authentication asoAuth2. - Credential Required: Connect your asanaOAuth2Api credentials.
- Filter High Risk Findings outputs to both Post Google Chat Alert and Generate Asana Urgent Task in parallel.
$json.space is not provided by upstream data, Google Chat messages will fail—set a fixed space ID or ensure upstream data includes it.Step 6: Test and Activate Your Workflow
Verify the full execution path before turning the workflow on.
- Click Execute Workflow to run the Hourly Schedule Trigger manually.
- Confirm that Retrieve Brand Mentions returns data and Process Search Insights outputs individual items.
- Check that Reputation Risk Evaluator produces JSON and Normalize AI Results returns clean fields like
risk_level. - For a high-risk test, temporarily set Filter High Risk Findings to match
Lowand confirm both Post Google Chat Alert and Generate Asana Urgent Task run. - When satisfied, switch the workflow Active toggle on to enable hourly monitoring.
Common Gotchas
- Google Chat credentials can expire or need specific permissions. If things break, check the Google Chat connection in n8n’s Credentials section 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
About 30 minutes if you already have SerpAPI, Google Chat, and Asana credentials ready.
No. You’ll mainly connect accounts and edit a few fields like keywords and risk threshold.
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 SerpAPI usage and Azure OpenAI token costs, which vary based on how many mentions you process.
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.
Yes, but plan it. Most teams duplicate the SerpAPI search input and add a brand field, then adjust the AI agent prompt to score risk per brand and include the brand name in the Google Chat message. You can also route different brands to different Chat spaces and Asana projects, so the right people see the right issues. If you manage clients, this is the difference between “cool demo” and a real service.
Usually it’s an invalid or rotated SerpAPI key. Update the credential in n8n, then confirm your SerpAPI plan supports the search mode you’re calling. If the workflow suddenly returns empty results, it can also be your query getting too narrow (or too broad), so check the exact keyword string being sent in the “Retrieve Brand Mentions” step.
It depends on your SerpAPI limits and your n8n execution capacity, but handling dozens of mentions per hour is realistic for most small teams.
Often, yes, because the “hard part” here is the decision-making in the middle. n8n is comfortable with branching logic (filtering high-risk items), normalization steps, and AI agent flows without turning into an expensive pile of premium tasks. You also get the option to self-host, which matters when you’re running something hourly, all month. Zapier or Make can still work if you only want a simple “search → send message” chain and you’re fine with more noise. If you’re unsure, Talk to an automation expert and we’ll point you to the simplest setup that still catches real risk.
This is what “always-on” reputation monitoring should feel like: quiet most of the time, loud only when it needs to be. Set it up once, and keep your team focused on responses that actually protect the brand.
