Evidence trail: SEO Audit API on RapidAPI · Web Content & URL Tools MCP Server on Apify

Missing titles, duplicate headings and images without alt text are easy to miss by eye. One GET request scores a page out of 100 and lists the issues by priority, each with a fix.

Subscribe to the free plan on RapidAPI, then call the endpoint with your RapidAPI key:

curl -G 'https://seo-audit12.p.rapidapi.com/v1/seo-audit' \
  --data-urlencode 'url=https://avaloncompany.ai/' \
  -H 'x-rapidapi-host: seo-audit12.p.rapidapi.com' \
  -H 'x-rapidapi-key: YOUR_RAPIDAPI_KEY'

We ran the same check against our own site while writing this post. The key fields of the real response:

{
  "score": 86,
  "grade": "A",
  "issues_by_severity": {
    "medium": 2
  }
}

import requests

resp = requests.get(
    'https://seo-audit12.p.rapidapi.com/v1/seo-audit',
    params={'url': 'https://avaloncompany.ai/'},
    headers={'x-rapidapi-host': 'seo-audit12.p.rapidapi.com', 'x-rapidapi-key': 'YOUR_RAPIDAPI_KEY'},
    timeout=30,
)
resp.raise_for_status()
print(resp.json())

• Check a new page before you publish it.
• Run it on every page in a sitemap to find the worst ones first.
• Add it to CI so a template change that drops the meta description is caught.

• It audits one page's HTML; it does not crawl the site or check rankings and backlinks.
• It does not run JavaScript, so content injected in the browser is not seen.

The same endpoint is one of the tools in the Web Content & URL Tools MCP Server on Apify. Point any client that supports remote MCP servers at `https://avalonai–web-content-url-tools-mcp.apify.actor/mcp` with your Apify token (`YOUR_APIFY_TOKEN`) and the agent can call it directly: https://apify.com/avalonai/web-content-url-tools-mcp
