SEO Audit Tool: letter grade for every URL

🩺 What is SEO Audit?

Paste a list of addresses and SEO Audit reads each one like a consultant would. Every website gets a report that puts the most damaging fixes on top, covering titles, headings, images, canonicals and load times. Schedule it weekly and watch what changes.

• Agencies and freelancers: audit a client's key pages in one run and send the ranked fix list as a report
• Site owners and marketers: check every landing page before a launch and after each release
• SEO monitoring: schedule weekly audits and get alerted when a score drops or links break
• Lead generation for SEO services: score prospects' homepages and open the conversation with their top three issues
• AI agents: let Claude or ChatGPT audit a page through MCP and explain the fixes

✨ Why use this Actor?

• ✅ One number, clear priorities: score, grade and four group scores, with issues sorted errors first, then by weight
• ✅ On-page, links and speed in one run: 19 checks from title length to unreachable targets and Core Web Vitals
• ✅ Real-user Core Web Vitals: Chrome user data first, lab values where it is missing, judged by Google's thresholds
• ✅ Fair scores: checks that did not run (links off, no PageSpeed key) are left out of the score instead of counting as failed
• ✅ Polite crawling: robots.txt respected for the page and every link, retries with backoff on 429 and 5xx
• ✅ Pay only for audited pages: unreadable ones get an error row and cost nothing

🚀 How to use SEO Audit

SEO Audit works in a few clicks, no coding needed:

1. Create a free Apify account (the free plan includes 5 USD of monthly credit).
2. Open SEO Audit and click Try for free.
3. Paste the pages you want audited, up to 200. Leave link checks and Core Web Vitals on for the full report.
4. Click Start and wait for the run to finish (most runs take seconds).
5. Download your data as JSON, CSV, Excel, XML or HTML, or send it straight to Google Sheets, Make, Zapier or your AI agent.

⬇️ Input

Add the pages to audit; everything else is optional and has sensible defaults.

Link checks

On by default, checkLinks tests up to maxLinksPerPage links and images of each page (100 unless changed, up to 500) for 4xx, 5xx, unreachable and redirected targets. Turn it off to skip this step; the group is then left out of the score.

Core Web Vitals

On by default, coreWebVitals measures each page with Google PageSpeed Insights on the strategy device (mobile or desktop) and adds 10 to 30 seconds to its audit. Your own free API key for it goes in apiKey.

How the score works

Every check is a pass (full points), a warning (half) or an error (none), weighted by importance. Grades: A from 90, B from 80, C from 65, D from 50, F below.

Field	Type	What it does	Default
Pages (urls)	array	Pages to audit, one report each.	["https://apify.com/"]
Check links (checkLinks)	boolean	Check every link and image on the page for broken (4xx, 5xx, unreachable) and redirected targets.	true
Links checked per page (maxLinksPerPage)	integer	At most this many links per page are checked (first on the page first).	100
Core Web Vitals (coreWebVitals)	boolean	Measure Lighthouse performance, LCP, CLS and INP with Google PageSpeed Insights (adds 10 to 30 seconds per page).	true
Device (strategy)	string	Device profile for Core Web Vitals.	"mobile"
PageSpeed Insights API key (apiKey)	string	Your own free Google API key with the PageSpeed Insights API enabled.
Maximum retries (maxRetries)	integer	Retries per request with exponential backoff on network errors, 429 and 5xx.	2

Input example

{
    "urls": [
        "https://example.com/"
    ]
}

⬆️ Output

Every page becomes one row with its score, grade, group scores, ranked issues, on-page facts, link statuses, Core Web Vitals and every check with its result. A run summary in the key-value store (OUTPUT) counts the pages audited and lists any that failed.

Broken links in the report

When a link is broken, links.broken names each one with its status (iana.org/help/example-domains in our test run, 3 of 26 checked):

{
    "checked": 26,
    "broken": [
        {
            "url": "https://www.icann.org/",
            "status": 403,
            "result": "broken"
        },
        {
            "url": "https://www.icann.org/privacy/policy",
            "status": null,
            "result": "broken: Timed out after 30 s without an answer (gave up after 3 attempts)"
        }
    ],
    "redirected": 2,
    "skipped": 0
}

View the results as a table or JSON in the Output tab and download them as JSON, CSV, Excel, XML, HTML or RSS, all fields or only those you pick.

⚠️ Error items

An input that cannot be read does not stop the run and is never charged: it gets a row with an error field so you can see exactly what failed.

Error	Meaning
HTTP 404	The page answered with an error status (any 4xx or 5xx)
Not an HTML page	The URL is a PDF, image or other file, not a web page
blocked by robots.txt	The site's robots.txt does not allow the page to be read

💰 How much does SEO Audit cost?

SEO Audit is priced per event: 32 USD per 1,000 audits (0.032 USD per audit), with no monthly rental. Each audited page is charged once; unreadable ones get an error row and cost nothing. Link checks and Core Web Vitals are included in the price.

You get	You pay
100 audits	3.2 USD
1,000 audits	32 USD
10,000 audits	320 USD
100,000 audits	3,200 USD

💡 Apify's free plan gives you 5 USD of credit every month, enough for about 156 audits at no cost. Set a spending limit per run and the Actor stops there.

🔌 Integrations, API and MCP

Connect SEO Audit to your AI agent (MCP)

Give Claude, ChatGPT, Cursor or any MCP client direct access to SEO Audit through the Apify MCP server. Add this URL to its settings:

https://mcp.apify.com/?actors=bepolabs/seo-audit

For Claude Desktop, add it under mcpServers in claude_desktop_config.json:

{
    "mcpServers": {
        "seo-audit": {
            "command": "npx",
            "args": [
                "-y",
                "@apify/actors-mcp-server",
                "--actors",
                "bepolabs/seo-audit"
            ],
            "env": {
                "APIFY_TOKEN": "<your Apify API token>"
            }
        }
    }
}

Then ask: "Run an SEO audit of https://www.python.org/ and tell me the three fixes that would raise its score the most."

Run it from your code

Python (pip install apify-client):

from apify_client import ApifyClient

client = ApifyClient("<YOUR_APIFY_TOKEN>")
run = client.actor("bepolabs/seo-audit").call(run_input={"urls":["https://example.com/"]})
for item in client.dataset(run["defaultDatasetId"]).iterate_items():
    print(item)

JavaScript (npm install apify-client):

import { ApifyClient } from 'apify-client';

const client = new ApifyClient({ token: '<YOUR_APIFY_TOKEN>' });
const run = await client.actor('bepolabs/seo-audit').call({"urls":["https://example.com/"]});
const { items } = await client.dataset(run.defaultDatasetId).listItems();
console.log(items);

No-code integrations

Send results to Google Sheets, Slack, Airtable, HubSpot, Make, Zapier, n8n and more from the Integrations tab, start runs on a schedule, or trigger your own endpoint with a webhook when a run finishes. The Apify API gives you full control over runs and datasets.

❓ FAQ

What does the score mean?

It is the weighted share of checks the page passes: a pass counts fully, a warning half, an error not at all. 90 or more is an A, 80 a B, 65 a C, 50 a D, anything lower an F.

Why is the performance score empty?

Core Web Vitals need a Google PageSpeed Insights key (the Actor's own or yours in apiKey). Without one, or if the measurement fails, the other three groups are scored and coreWebVitalsNote says why.

Can it audit a whole website?

It audits the pages you list, up to 200 per run. To audit a whole site, get its URLs first, for example from its sitemap, and pass them in.

Mobile or desktop?

Core Web Vitals are measured for the device in strategy (mobile by default, as Google indexes mobile-first). Run twice to compare both.

How long does a run take?

Usually a few seconds per page for on-page and link checks, plus 10 to 30 more with Core Web Vitals. A target that never answers adds up to half a minute. Three pages are audited at a time.

Can I monitor my pages every week?

Yes: add a schedule in Apify and connect Slack, e-mail, Google Sheets or a webhook to get each new report.

Is it legal to use SEO Audit?

Yes, for your own sites and those of your clients. The Actor reads public pages the way a browser does, with its own user agent, one request per page and link, and obeys each site's robots.txt. Core Web Vitals come from the official PageSpeed Insights API under the Google APIs Terms of Service. No personal data is collected.
