This AlekSystem workflow demonstrates how to monitor competitor websites for SEO changes by scraping content and updating a Google Sheet. It uses the Scraper node from customjs.space to extract HTML content and parse key SEO elements like title, `, `, and meta description. What this workflow does Reads a list of competitor websites from a Google Sheet. Uses the CustomJS Scraper node to fetch raw HTML for each website. Extracts important SEO data: Page title `` headings `` headings Meta description Updates the Google Sheet with the latest scraped values and a timestamp. Compares the new values with the previous ones: If changes are detected, a Slack notification is sent. Requirements CustomJS API key for the Scraper node. A Google Sheet containing competitor website URLs. Slack workspace (optional, for notifications). Workflow Steps Schedule Trigger Runs automatically (weekly by default, adjustable as needed). Google Sheets – Get Competitor URLs Reads competitor website URLs from the configured sheet. CustomJS Scrape – Website Inputs each website URL. Returns raw HTML text for analysis. Code – Extract SEO Elements Parses the HTML to extract: Title H1s H2s Meta description Google Sheets – Update SEO Data Updates the sheet with the new SEO data and a current date.

Track additional elements* by extending the regex in the *Code Node**. Send alerts to other platforms** (e.g., Email, Microsoft Teams, Discord) by swapping the Slack node. Store results in a database** instead of Google Sheets if long-term history is required.
