How to Automate SEO Workflows with Serpent API and Zapier

Why Automate SEO with Zapier?

The Manual SEO Reporting Problem

The typical SEO reporting workflow looks something like this: open a rank tracking tool, export data to CSV, copy it into a Google Sheet, create charts, write commentary, format everything, and email it to stakeholders. This process takes 2 to 4 hours per week for a modest keyword set. Multiply that across multiple clients or business units, and you are looking at a significant portion of your work week consumed by reporting rather than strategy.

Manual processes also introduce errors. Someone forgets to run the check on Tuesday. The spreadsheet formula breaks because a new row was inserted in the wrong place. The report goes out a day late because the person responsible was on vacation. Automation removes all of these failure points.

Why Zapier Specifically?

Zapier is not the only automation platform. Make (formerly Integromat), n8n, and Pipedream all offer similar capabilities. Zapier's advantages for this use case are its enormous app ecosystem (6,000+ integrations), reliable scheduling, built-in error handling, and a gentle learning curve for non-technical team members. If your marketing team needs to maintain these automations after you set them up, Zapier's visual interface is the easiest to hand off.

What You Can Automate

• Daily rank tracking — Check keyword positions every morning and log them to a spreadsheet
• Ranking change alerts — Get a Slack message or email when a keyword drops below a threshold
• Competitor monitoring — Track which competitors appear for your target keywords
• News monitoring — Get notified when your brand or industry keywords appear in news results
• Automated reports — Compile weekly ranking summaries and email them to stakeholders
• Content gap alerts — Discover new search features (PAA, featured snippets) for your keywords

Prerequisites and Setup

What You Need

1. Serpent API key — Sign up at apiserpent.com to get your API key. The free tier includes 100 searches to test your workflows.
2. Zapier account — A free account works for simple automations. Paid plans unlock multi-step Zaps and faster polling intervals.
3. Google Sheet — Create a spreadsheet with columns for Date, Keyword, Position, URL, and Title. This will serve as your ranking database.
4. Slack workspace (optional) — For sending ranking alerts to a channel.

Serpent API Quick Reference

The key endpoints you will use in Zapier automations:

Connecting Serpent API via Webhooks

Zapier does not have a native Serpent API integration (yet), but the Webhooks by Zapier app makes connecting any REST API straightforward. Here is how to set up the connection.

Step 1: Create a New Zap

In your Zapier dashboard, click "Create Zap." For the trigger, choose Schedule by Zapier and set it to run daily at your preferred time (e.g., 8:00 AM). This ensures your rank tracking runs consistently every morning before your team starts work.

Step 2: Add a Webhooks Action

Add an action step and search for Webhooks by Zapier. Choose the GET request type. Configure it as follows:

URL: https://apiserpent.com/api/search

Query String Params:
  q        = your target keyword
  engine   = google
  num      = 10
  apiKey   = YOUR_SERPENT_API_KEY

Set the Headers to include Accept: application/json. Click "Test action" to verify the connection. You should see a JSON response with search results.

Step 3: Parse the Response

The Serpent API returns structured JSON with an organic array inside results. Each organic result contains position, title, url, and snippet fields. Zapier automatically parses the JSON, so you can reference these fields in subsequent steps using dot notation like results__organic__1__position.

Finding Your Domain in Results

To check where your domain ranks, add a Code by Zapier step (JavaScript) after the webhook:

// Code by Zapier - JavaScript
const results = JSON.parse(inputData.body);
const organic = results.results?.organic || [];
const myDomain = "yourdomain.com";

const match = organic.find(r => r.url.includes(myDomain));

output = [{
  found: match ? "yes" : "no",
  position: match ? match.position : "not found",
  url: match ? match.url : "",
  title: match ? match.title : "",
  keyword: inputData.keyword,
  date: new Date().toISOString().split('T')[0]
}];

Workflow 1: Automated Rank Tracking to Google Sheets

This is the most common automation. Every day, Zapier queries Serpent API for each of your target keywords, finds your domain's position, and logs the data to a Google Sheet.

The Complete Zap

1. Trigger: Schedule by Zapier — Every day at 8:00 AM
2. Action 1: Looping by Zapier — Loop through a list of keywords (stored in a separate "Keywords" sheet)
3. Action 2: Webhooks by Zapier (GET) — Call Serpent API for each keyword
4. Action 3: Code by Zapier — Extract your domain's position from the results
5. Action 4: Google Sheets — Create a new row with Date, Keyword, Position, URL, Title

Handling Multiple Keywords

The Looping by Zapier step is the key to scaling this to dozens or hundreds of keywords. Store your keyword list in a Google Sheet tab called "Keywords" with one keyword per row. The loop iterates through each keyword and runs the API call and logging steps for each one.

For large keyword sets (100+ keywords), consider splitting across multiple Zaps that run at different times to stay within Zapier's task limits and Serpent API's rate limits. A daily check of 100 keywords at Scale pricing costs approximately $0.005 per day, or about $0.15 per month.

Building the Dashboard

Once data is flowing into your Google Sheet, you can build charts directly in Sheets or connect to Google Looker Studio (formerly Data Studio) for more sophisticated visualization. Create a line chart with Date on the X axis and Position on the Y axis (inverted, so position 1 is at the top) to see ranking trends over time.

Workflow 2: Ranking Drop Alerts

Knowing that a keyword dropped from position 3 to position 15 the same day it happens is far more valuable than discovering it in next week's report. This workflow sends an immediate alert when a significant ranking change occurs.

The Alert Zap

1. Trigger: Schedule by Zapier — Every day at 8:00 AM
2. Action 1: Google Sheets — Look up the previous day's position for each keyword
3. Action 2: Webhooks by Zapier — Fetch current ranking from Serpent API
4. Action 3: Code by Zapier — Compare current vs previous position
5. Action 4: Filter by Zapier — Only continue if position dropped by 5 or more
6. Action 5: Slack — Send alert to your SEO channel

The Comparison Logic

// Code by Zapier - Compare positions
const previousPos = parseInt(inputData.previousPosition) || 0;
const currentPos = parseInt(inputData.currentPosition) || 0;
const keyword = inputData.keyword;

let change = previousPos - currentPos; // positive = improvement
let status = "stable";
let emoji = "";

if (change >= 5) {
  status = "improved";
  emoji = "up";
} else if (change <= -5) {
  status = "dropped";
  emoji = "down";
}

output = [{
  keyword,
  previousPosition: previousPos,
  currentPosition: currentPos,
  change: Math.abs(change),
  direction: change > 0 ? "up" : "down",
  status,
  alert: Math.abs(change) >= 5 ? "yes" : "no"
}];

Slack Alert Format

In the Slack step, format your message to be scannable:

Ranking Alert: "{{keyword}}"
Position: {{previousPosition}} -> {{currentPosition}} ({{direction}} {{change}})
Action needed: Review SERP for changes in competition or algorithm updates.

You can customize the threshold (the filter step) based on the keyword's value. For high-priority money keywords, you might alert on any change of 3+ positions. For long-tail terms, a threshold of 10+ keeps the noise down.

Workflow 3: Competitor Monitoring

This workflow tracks not just your own rankings, but who else appears in the top results for your keywords. It is invaluable for spotting new competitors entering your space or existing competitors gaining ground.

How It Works

1. Trigger: Schedule by Zapier — Weekly on Monday
2. Action 1: Webhooks by Zapier — Fetch top 20 results for each target keyword
3. Action 2: Code by Zapier — Extract all unique domains from results
4. Action 3: Google Sheets — Log domains, positions, and date
5. Action 4: Code by Zapier — Compare against known competitor list
6. Action 5: Filter — Continue only if a new domain appeared in top 10
7. Action 6: Email — Send weekly competitor digest

// Extract domains from SERP results
const results = JSON.parse(inputData.body);
const organic = results.results?.organic || [];
const knownCompetitors = ["competitor1.com", "competitor2.com", "competitor3.com"];

const domains = organic.map(r => {
  try {
    return new URL(r.url).hostname.replace('www.', '');
  } catch { return ''; }
}).filter(Boolean);

const newEntrants = domains.filter(d =>
  !knownCompetitors.includes(d) &&
  d !== "yourdomain.com"
);

output = [{
  topDomains: domains.slice(0, 10).join(", "),
  newEntrants: newEntrants.length > 0 ? newEntrants.join(", ") : "none",
  hasNewCompetitors: newEntrants.length > 0 ? "yes" : "no"
}];

Advanced: Multi-Step Zaps and Filters

News Monitoring Automation

Use the /api/news endpoint to monitor brand mentions in news articles. This is especially useful for PR teams and brand managers who need real-time visibility into media coverage.

URL: https://apiserpent.com/api/news

Query String Params:
  q        = "your brand name"
  engine   = google
  num      = 20
  apiKey   = YOUR_SERPENT_API_KEY

Add a Filter by Zapier step to only continue when new articles are found (check that the results count is greater than zero). Then send the article titles and URLs to Slack, email, or a tracking spreadsheet.

Using Paths for Conditional Logic

Zapier's Paths feature lets you branch your workflow based on conditions. For rank tracking, you could create three paths:

• Path A: Position improved by 5+ → Send congratulatory Slack message
• Path B: Position dropped by 5+ → Send urgent alert and create a task in Asana/Trello
• Path C: Position stable → Just log to spreadsheet, no notification

Storing API Keys Securely

Never hardcode your Serpent API key directly in Zap configurations where team members can see it. Use Zapier's Secret Manager (available on Team plans) or store the key in a Google Sheet cell and reference it dynamically. This also makes key rotation easier: update one cell instead of editing every Zap.

Cost Analysis and Optimization

One of the main advantages of building on Serpent API rather than premium rank tracking tools is cost. Here is what typical automation workflows cost:

Compare this with dedicated rank tracking tools that charge $50 to $500 per month for similar keyword volumes. The combination of Serpent API and Zapier gives you comparable functionality at a fraction of the cost, with the flexibility to customize every aspect of the workflow.

Optimizing API Usage

• Use quick search for top-10 checks — The /api/search/quick endpoint is faster and cheaper when you only need to know if you are in the top 10
• Batch by engine — DuckDuckGo searches are cheaper than Google. Use DDG for frequent checks and Google for weekly deep dives
• Cache with Zapier Storage — Store recent results in Zapier Storage to avoid re-fetching the same data in multi-step Zaps
• Skip weekends — Rankings rarely change significantly on weekends. Save 28% of your API costs by running only on business days
