1.1 Workflow description

Title: Beginner lead finder using SerpAPI search
Workflow name: Beginner lead finder using SerpAPI search

This n8n workflow finds experts on any topic, scrapes their websites, and pulls out contact emails automatically.
Core services used: SerpAPI (google search) · Apify (website crawler) · OpenAI (GPT-4o email extraction).

🛠️ Step-by-Step Setup & Execution

1️⃣ Run Workflow (Manual Trigger)

Node	Type	Purpose
`Run Workflow`	Manual Trigger	Start the workflow on demand while you test.

2️⃣ Set Your Topic

Node	Type	How to configure
`Set Topic`	Set	Add a string field Topic – e.g. `"n8n"`. This keyword drives every subsequent step.

3️⃣ Search Google (Results 1-10)

Node	Type	API Credential
`Search Google (top 10)`	SerpAPI	Create SerpAPI credential 1. Sign up → copy API key → n8n → Credentials → New → SerpAPI → paste. 2. Select the credential in this node.
Key Params
`q`		`={{ $json.Topic }} Expert`
`location`		Region code (ex `585069efee19ad271e9c9b36`)
`additionalFields.start`		`"10"` (Google position 1-10)

4️⃣ Search Google (Results 11-20)

Node	Type	Notes
`Search Google (11-20)`	SerpAPI (same credential)	Remove `start` or set to 20+ to fetch next page.

5️⃣ Extract URL Lists

Node	Type	Script Purpose
`Extract Url` & `Extract Url 2`	Code	Loop `data.organic_results` → output `{ title, link, displayed_link }` for each result.

6️⃣ Combine Both Result Sets

Node	Type	Details
`Append Results`	Merge (combineAll)	Merges arrays from steps 3 & 4 into a single list for processing.

7️⃣ Loop Over Every URL

Node	Type	Configuration
`Loop Over Items1`	Split In Batches	Default batch = 1 (process one page at a time). `onError = continueRegularOutput` keeps loop alive on failures.

8️⃣ Scrape Webpage Content (Apify)

Node	Type	API Credential
`Scrape URL with apify`	HTTP Request	Create Apify credential 1. Sign up at https://console.apify.com 2. Account → API tokens → copy. 3. n8n → Credentials → New → HTTP Query Auth → set query param `token=YOUR_TOKEN`.
Request Details
Method	POST
URL	`https://api.apify.com/v2/acts/6sigmag~fast-website-content-crawler/run-sync-get-dataset-items`
JSON Body	`json { "startUrls": ["{{ $json.link }}"] }`

9️⃣ Extract Email with OpenAI

Node	Type	API Credential
`Extract Email from webpage`	LangChain Agent	Create OpenAI credential 1. Generate key at https://platform.openai.com/account/api-keys 2. n8n → Credentials → New → OpenAI API → paste key.
Prompt (system)	`extract the email address from the text. if there is no email address, output null.`
Output Parser	`Structured Output Parser2` expects → `{ "email": "address OR null" }`

🔟 Loop Continues & Final Data

The extracted result returns to Loop Over Items1 until every URL is processed.

Typical final item JSON:

{
  "title": "How to Build n8n Workflows",
  "link": "https://example.com",
  "email": "[email protected]"
}

💡 Optional Enhancements Idea How Save Leads Add a Google Sheets or Airtable node after the loop. Validate Emails Chain a ZeroBounce / Hunter.io verification API before saving. Parallel Crawling Increase SplitInBatches size (watch Apify rate limits).

Find LinkedIn engagement opportunities with Apify, Gemini, Google Sheets and Slack

## Quick overview Youtube Video: https://youtu.be/ehsagyRmri4 This workflow runs on a schedule to scrape recent LinkedIn posts with Apify, stores and evaluates them in Google Sheets using Google Gemini, then enriches shortlisted authors with Apify profile data, saves profile results to a second Sheet, and sends Slack alerts for comment and connection opportunities. ## How it works 1. Runs on a schedule and sets the Ideal Customer Profile (ICP) text used for evaluation. 2. Scrapes LinkedIn posts from Apify using the configured search query and merges the results with existing rows from a Google Sheets “Linkedin_Outreach_oppurtunities” sheet. 3. Limits processing to two posts, upserts the post details into Google Sheets, and sends each post’s content to Google Gemini to score whether it is a comment opportunity. 4. If the post is marked as an opportunity with a confidence score above 80, the workflow updates the corresponding Google Sheets row with the AI reasoning and suggested comment angle. 5. Aggregates the qualified opportunities, compares their author profile URLs against an existing “Profile_scraper” Google Sheet, and keeps only authors that are not already present. 6. Scrapes each new author profile with an Apify profile scraper, uses Google Gemini to score ICP match, saves the profile details and qualification summary to the “Profile_scraper” Google Sheet, and posts a Slack message with the shortlisted profile link. 7. Separately, a Google Sheets trigger watches the opportunities sheet for row updates and sends a Slack alert containing the post link, reasoning, and comment angle. ## Setup 1. Add Apify credentials and verify the actor IDs and input parameters for the LinkedIn post scraper and the profile scraper. 2. Configure Google Sheets access (service account for read/write nodes and a Google Sheets Trigger OAuth connection) and update the document IDs/sheet tabs for both the opportunities sheet and the profile sheet. 3. Add Google Gemini (Google PaLM) credentials and confirm the selected Gemini model names in both AI evaluation steps. 4. Add Slack credentials, choose the target channel, and adjust the Slack message text if needed. 5. Customize the ICP text and the LinkedIn search query/posted time window to match the audience and volume you want to monitor.

Enrich existing HubSpot company records with Veridion

## Quick Overview This workflow manually enriches existing HubSpot companies using Veridion, skipping records already marked as enriched and updating HubSpot with matched company details like industry, location, and key firmographics. ## How it works 1. Runs when you manually execute the workflow. 2. Fetches up to 100 companies from HubSpot and includes key properties such as name, domain, phone, and the custom veridion_enriched flag. 3. Stops with a clear error if the veridion_enriched property is missing, otherwise filters to only companies not yet marked as enriched. 4. Retrieves full details for each selected HubSpot company and sends its name, domain/website, and phone to Veridion for enrichment. 5. Checks whether Veridion returns a match and skips companies without a match. 6. Maps key Veridion fields and updates the HubSpot company record with enriched details and sets veridion_enriched to true. ## Setup 1. Create the HubSpot company custom properties veridion_enriched (boolean/checkbox) and veridion_industry (single-line text). 2. Add HubSpot App Token credentials and ensure the HubSpot company list request includes veridion_enriched, veridion_industry, name, domain/website, phone, and hs_object_id. 3. Add Veridion API credentials and confirm your HubSpot companies have at least a name plus a domain/website or phone for best matching.

Identify company decision makers with Coresignal and Google Sheets

## Quick Overview This workflow manually pulls company website data from Google Sheets, finds matching companies in Coresignal, and searches for decision-maker employees. It then writes the resulting contact and company details back to a dedicated “Decision makers” sheet in Google Sheets. ## How it works 1. Manually starts the workflow and reads company rows from a Google Sheets spreadsheet. 2. Normalizes each company website URL into a clean domain and searches Coresignal for the matching company by website domain. 3. Processes companies in batches and writes placeholder “no employee found” company details to the “Decision makers” sheet in Google Sheets. 4. For each matched company, searches Coresignal for current employees whose titles match common executive and leadership roles. 5. If the title-based search does not return a single employee ID, runs a broader Coresignal decision-maker search that excludes HR-related roles and departments. 6. Retrieves detailed employee (and, when needed, company) fields from Coresignal and appends or updates the “Decision makers” sheet with names, titles, emails, LinkedIn URLs, and company information. ## Setup 1. Create a Google Sheets OAuth2 connection and set the source sheet (companies with a Website field) and the target “Decision makers” sheet in the Google Sheets nodes. 2. Create a Coresignal API credential in n8n and ensure your plan supports company and employee Elasticsearch DSL search and profile retrieval. 3. Confirm your input sheet includes a website column named either Website or website, and adjust the Coresignal title/department filters to match the decision-maker roles you want to capture.
