Tips for best results

• Start with a single URL to understand the output format before running bulk audits
• Schedule weekly runs to monitor SEO health over time and catch regressions
• Focus on critical issues first — they have the most impact on search rankings
• Use the issues list to create actionable tasks for your development team
• Compare competitors — audit your site and competitor sites to benchmark performance
• Check different page types — homepage, product pages, blog posts may have different SEO profiles
• Export to CSV/Excel for reporting — Apify supports JSON, CSV, and Excel exports

Integrations

SEO Audit Tool to Google Sheets — export audit results to a spreadsheet for team reviews and historical tracking. Schedule weekly runs to build an SEO health dashboard.

SEO Audit Tool to Slack/Discord — set up webhook notifications when critical issues are detected. Get alerts when your SEO score drops below a threshold.

SEO Audit Tool to Make/Zapier — trigger audits when new pages are published. Connect with your CMS to automatically audit every new blog post.

Scheduled monitoring — run daily or weekly audits on your key pages. Compare scores over time to track improvement.

CI/CD integration — use the Apify API to run an audit before deploying to production. Fail the build if critical SEO issues are found.

Using the Apify API

Node.js:

import { ApifyClient } from 'apify-client';

const client = new ApifyClient({ token: 'YOUR_API_TOKEN' });
const run = await client.actor('automation-lab/seo-audit-tool').call({
    urls: ['https://example.com'],
});
const { items } = await client.dataset(run.defaultDatasetId).listItems();
console.log(items[0].overallScore, items[0].overallGrade);

Python:

from apify_client import ApifyClient

client = ApifyClient("YOUR_API_TOKEN")
run = client.actor("automation-lab/seo-audit-tool").call(
    run_input={"urls": ["https://example.com"]}
)
items = client.dataset(run["defaultDatasetId"]).list_items().items
print(items[0]["overallScore"], items[0]["overallGrade"])

cURL:

curl -X POST "https://api.apify.com/v2/acts/automation-lab~seo-audit-tool/runs?token=YOUR_API_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"urls": ["https://example.com"]}'

Use with AI agents via MCP

SEO Audit Tool is available as a tool for AI assistants that support the Model Context Protocol (MCP).

Add the Apify MCP server to your AI client — this gives you access to all Apify actors, including this one:

Setup for Claude Code

$claude mcp add --transport http apify "https://mcp.apify.com"

Setup for Claude Desktop, Cursor, or VS Code

Add this to your MCP config file:

{
    "mcpServers": {
        "apify": {
            "url": "https://mcp.apify.com"
        }
    }
}

Your AI assistant will use OAuth to authenticate with your Apify account on first use.

Example prompts

Once connected, try asking your AI assistant:

• "Run an SEO audit on https://mywebsite.com and summarize the critical issues (use automation-lab/seo-audit-tool)"
• "Compare the SEO scores of these 5 competitor websites and rank them"
• "Audit all pages in my sitemap and create a spreadsheet of issues sorted by severity"

Learn more in the Apify MCP documentation.

Is it legal to run SEO audits?

Yes. SEO Audit Tool only accesses publicly available information — the same data that search engine crawlers see. It sends standard HTTP requests and reads public HTML, robots.txt, and sitemap.xml files. The tool does not bypass any authentication, CAPTCHAs, or access restrictions.

All data collection complies with GDPR and other data protection regulations. The tool only extracts technical metadata about page structure, not personal data.

FAQ

How fast is the SEO audit? Each URL takes 2-5 seconds to audit. The tool runs checks in parallel where possible (HTTP request, SSL check, robots.txt, sitemap.xml all fetched simultaneously). A 100-URL audit completes in approximately 5 minutes.

What does the overall score mean? The 0-100 score is a weighted average of 10 category scores. Each category tests specific SEO best practices. An A grade (90+) means excellent SEO health. A C grade (55-74) means significant issues need attention. An F grade (below 35) indicates critical problems.

How does this compare to tools like Screaming Frog or Ahrefs? SEO Audit Tool focuses on per-page on-page SEO analysis. It covers meta tags, headings, images, structured data, and technical signals. It does not crawl entire websites for broken links or analyze backlink profiles — for that, use dedicated crawling tools. The advantage is speed, simplicity, and API-first design for automation.

Why are some fields null in the output? Fields like title, metaDescription, or h1 return null when the corresponding HTML element is not found on the page. This is intentional — a null value indicates a missing SEO element that should be added.

Why is my score lower than expected? The audit checks 10 categories with strict best-practice thresholds. Common score reductions: missing Open Graph tags (-15), no structured data (-30), missing canonical URL (-15), no sitemap.xml (-10). Review the issues array to see exactly what reduced your score.
