# Compare Sitemap Snapshots for Added and Removed URLs

**Use case:** 

Compare a sitemap with a previous SNAPSHOT to identify added, removed, changed and unchanged URLs. This preset uses a real sitemaps.org snapshot from September 19, 2026; replace both inputs with your own matching scope. Returns one row per URL. Price: $0.001 per run + $0.0005 per returned URL (about $0.043 for this 84-URL example).

## How it works

### 1. Sign up on Apify or log in

The Sitemap Diff — Added, Removed & Changed URLs Actor is ready to run with the inputs already set for "Compare Sitemap Snapshots for Added and Removed URLs". [Sign up or log in](https://console.apify.com/create-task-from-example/z6TlhnjAwV3f1db12) and you'll land in Apify Console with a copy of this exact task.

### 2. Start the "Compare Sitemap Snapshots for Added and Removed URLs" task

The Sitemap Diff — Added, Removed & Changed URLs Actor will start running based on the input automatically. You can also change all the input fields, like sitemap urls, maximum urls, and more, to match your specific use case.

### 3. Receive the "Compare Sitemap Snapshots for Added and Removed URLs" output

Monitor the progress in real time. You will be notified as soon as your dataset is complete and ready for review. Each result includes data such as URL, change, last modified, and more.

### 4. Integrate into your workflow

The final output is delivered in JSON, CSV, or Excel format, ready to be plugged into your workflow. You can also [run the "Compare Sitemap Snapshots for Added and Removed URLs" task via API](https://apify.com/gertner-data/sitemap-delta.md).

## About this Actor

This example demonstrates how to use [Sitemap Diff — Added, Removed & Changed URLs](https://apify.com/gertner-data/sitemap-delta.md) with a specific input configuration. Visit the [Actor detail page](https://apify.com/gertner-data/sitemap-delta.md) to learn more, explore other use cases, and run it yourself.


## How to integrate an Actor?

This Task's input is already configured above. Use it as-is rather than inventing a new one.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For full API examples (JavaScript, Python, CLI, MCP, OpenAPI), see this Task's Actor page: https://apify.com/gertner-data/sitemap-delta.md

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).
