N8N SEO Automation: Scan and Optimize Metatags

How can n8n help with SEO?

n8n (short for "nodemation") is an open-source workflow automation tool that lets you connect apps, APIs, and services using a visual editor — no (or low) code required. Think of it as a self-hostable alternative to Zapier or Make, but with much more flexibility.

While n8n isn’t an SEO tool out of the box, it can automate SEO-related tasks and connect to your favorite SEO tools or APIs. Here’s how it can help:

• Scan Websites for Meta Tags
• Automate Bulk URL Audits
• Generate SEO Report
• Connect to SEO APIs
• Schedule SEO Tasks

What are we going to build?

A simple SEO scanner tool, where you provide the sitemap URL to loop through each URL and check if they have a meta title and description, and check if they have a valid length (not too short to too long). When the analysis is done, it provides a report in Google Sheets and can send you an email.

Step 1: Trigger Nodes

Let's add 2 Nodes for triggering the workflow

1. Manual Click Trigger
2. On Form Submission Trigger

For the form submission, add email and sitemap as required fields

Step 2: Fetching the Sitemap

Before getting started, create a new Google Sheet with the following header:

And link your Google Account and add your Google OAuth ID and Secret to the Google Sheet settings.

In this section, we are cleaning the sheet to have fresh data, making an HTTP request to the Sitemap URL, and pulling the URLs and adding them to the Sheet URLs (We will use this column as a unique identifier of each row for updating rows next step)

Clear Sheet

HTTP Request

XML to JSON

Sanitize and Cleanup code

Create a code node to run once for all, and add return $input.first().json.urlset.url to it to return all URL objects in an array

Step 3: Update Sheet with URLs and Metatags

Our next step is to add all of the URLs and their meta tags, titles, and descriptions to the Google Sheet so we can use it to analyze if they pass our checks or not. The following workflow shows how we can extract meta tags (title, description) in n8n.

Let's create 2 branches from the last node from the previous step One node will be to add all of the sitemap URLs to the sheet, and nodes in the other branch will take care of fetching each URL's meta title and description and adding them to the Google Sheet using the URL as unique identifier.

GET Page Data

Parse Meta Tags

Add a code node with the following code to run once for each item

Update Sheet with Metatags

Step 4: Process Tags and Generate the Report

After the previous node, add a new code node to run once for each item to check the title and description length

Next, split into 2 branches, one for updating the sheet with the checks

Now let's convert the checks to an HTML table and send the report via email to the address entered in the initial form
