# Compare every sitemap URL: old site vs new site

**Use case:** 

No path list needed: every URL in the old site's sitemap.xml is fetched on both sites and diffed (status, redirects, title, meta, canonical, robots, headings, word count, structured data). The sample compares 25 apify.com URLs with themselves; set targetBaseUrl to your new site.

## Input

```json
{
  "sourceBaseUrl": "https://apify.com",
  "targetBaseUrl": "https://apify.com",
  "paths": [
    "/",
    "/pricing",
    "/about",
    "/contact"
  ],
  "discoverPathsFromSitemap": true,
  "maxPaths": 25,
  "checkBrokenLinks": false,
  "wordCountTolerancePercent": 10,
  "responseTimeTolerancePercent": 50,
  "ignoreFields": [],
  "onlyReportPathsWithDifferences": false,
  "maxConcurrency": 5,
  "requestTimeoutSecs": 30,
  "respectRobotsTxt": true,
  "outputDetail": "detailed",
  "debug": false
}
```

## Output

```json
{
  "path": {
    "label": "Path",
    "format": "string"
  },
  "score": {
    "label": "Score",
    "format": "integer"
  },
  "worstSeverity": {
    "label": "Worst",
    "format": "string"
  },
  "differenceCount": {
    "label": "# diffs",
    "format": "integer"
  }
}
```

## 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/moonweil/website-migration-qa.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`).
