DIY Website Monitoring Options

If you‘re technically inclined, you can build your own custom website monitoring solution. Here are a few options:

Write a Script

For developers, writing a web scraping script in Python, Node, Go or another language is a DIY option. The script would scrape and compare site data on a schedule. When changes are detected, you can send programmatic notifications via email, Slack webhook, SMS, etc.

This gives you total control to tailor the monitoring to your specific needs. But it requires coding knowledge.

Automation Tools

Another coder-friendly option is using an automation tool like Zapier or Integromat. These tools let you quickly build workflows and bots using a visual interface to connect apps and services.

You could automate regularly scraping a site, comparing for changes, and sending notifications without writing raw code. Basic plans for these tools start around $20/month.

Website Change Detection Services

Some API-based website change detection services like DiffBot and OnWebChange provide an easy way to monitor pages without coding.

They allow submitting URLs via API calls to scan for changes and retrieve diff results. You would need to handle scheduling scans and sending notifications though. Plans start around $30/month for basic usage.

Cloud Platforms

Finally, leveraging serverless platforms like AWS, Azure, or Google Cloud Platform is an option. You could build scripts to run on cloud infrastructure in an automated way for website monitoring.

This gives you scale once configured but requires significant technical knowledge. Costs vary based on cloud usage.

Key Things to Monitor on Websites

When setting up website monitoring, consider which elements of a page you care about tracking for changes:

  • Text content: Monitor article text, product descriptions, code snippets, etc.

  • Visual media: Track changes to images, videos, and other visuals on a site.

  • Page layout: Keep an eye on design changes to page structure and styling.

  • Data/tables: Watch for changes made to any data sets, tables, or databases shown on pages.

  • Source code: Check for underlying code changes like HTML, CSS, JS, etc.

  • Prices: For ecommerce, confirm price changes for products.

  • Availability: See when inventory comes back in stock (or sells out).

  • Navigation/menus: Follow changes made to site navigation links and menus.

  • New content: Get alerts when new pages, blog posts, content, etc. gets published.

Think carefully about which page elements are most important to track for the websites you want to monitor. This ensures your monitoring tool or script is configured properly.

Tips for Effective Website Monitoring

Follow these tips to ensure your website monitoring is set up for success:

Pick the right sites – Select sites and pages that actually matter to track. Monitoring irrelevant websites is a waste.

Limit pages per site – Start by monitoring just 1-2 important pages per site. You can expand over time.

Use site maps – Leverage a site‘s XML site map to discover new pages to monitor as they get added.

Define an update schedule – Daily, weekly, or monthly checks are likely fine. Avoid over-monitoring.

Test accuracy – Spot check monitoring results periodically to confirm changes are caught.

Fine-tune selectors – If too many false positives, tweak your element selectors to hone in on the right data.

Consider uptime tracking – Combine uptime monitoring with content changes for a full website view.

Review notifications – When you receive alerts, review them in a timely manner.

Automate responses – Use Zapier, IFTTT, or APIs to trigger actions based on monitoring alerts.

By putting these tips into practice, you‘ll get the most out of whatever website monitoring solution you choose to use.
