# Vet Guest Post and Link Building Sites

**Use case:** 

Sort candidate sites for guest posts or link building by referring subnets and authority score, and drop the ones with no real link profile before you pay for a placement. Replace the example blogs with your own list.

## Input

```json
{
  "domains": [
    "smashingmagazine.com",
    "css-tricks.com",
    "dev.to",
    "hashnode.com",
    "sitepoint.com",
    "freecodecamp.org"
  ],
  "maxDomains": 100,
  "includeNotRanked": true
}
```

## Output

```json
{
  "domain": {
    "label": "Domain",
    "format": "text"
  },
  "openAuthorityScore": {
    "label": "Open authority score (0-100)",
    "format": "number"
  },
  "majesticGlobalRank": {
    "label": "Majestic rank",
    "format": "number"
  },
  "refSubnets": {
    "label": "Referring subnets",
    "format": "number"
  },
  "refIPs": {
    "label": "Referring IPs",
    "format": "number"
  },
  "rankChange": {
    "label": "Rank change",
    "format": "number"
  },
  "openPageRank": {
    "label": "Open PageRank (0-10)",
    "format": "number"
  },
  "inMajesticTop1M": {
    "label": "In top 1M",
    "format": "boolean"
  },
  "error": {
    "label": "Error",
    "format": "text"

## About this Actor

This example demonstrates how to use [Domain Authority Checker: Backlink Rank from Open Data](https://apify.com/jtpalms/domain-authority-checker.md) with a specific input configuration.

## 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/jtpalms/domain-authority-checker.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`).
