SEOPeek vs Sitechecker Pro — SEO Audit API Compared

Sitechecker Pro is a popular website monitoring and SEO audit platform—it crawls your entire site, tracks changes over time, and surfaces issues through a visual dashboard. Plans run from $29 to $249 per month. But if what you actually need is a fast, programmable SEO audit API you can call from code, Sitechecker does not offer one. SEOPeek is a developer-first alternative: one GET request returns a JSON audit with 20 on-page checks and a numeric score in under 2 seconds, starting at $0/month. This guide compares the two tools across pricing, features, speed, and workflow fit so you can pick the right one.

1. What Sitechecker Pro Does

Sitechecker Pro is a website monitoring and SEO audit platform built around full-site crawls and a visual dashboard. You add your website, Sitechecker crawls every page it can find, and it produces a comprehensive report organized by issue severity. The platform then monitors your site on an ongoing basis, alerting you when new issues appear or existing ones change.

The core features include:

• Site crawler: follows internal links, checks HTTP status codes, discovers orphan pages, and maps your site structure
• On-page SEO audit: checks title tags, meta descriptions, headings, image alt text, canonical tags, and Open Graph metadata
• Technical SEO: identifies broken links, redirect chains, duplicate content, slow pages, and mixed content issues
• Rank tracking: monitors keyword positions across search engines and tracks changes over time
• Backlink monitoring: tracks new and lost backlinks, monitors referring domains
• Change detection: alerts you when key on-page elements (titles, descriptions, robots directives) change unexpectedly
• Chrome extension and web interface: designed for non-technical users who prefer visual reports over raw data

Sitechecker is designed for marketing teams, SEO managers, and small agencies who need a visual dashboard to monitor website health over time. It is a solid tool for its intended audience. The key limitation for developers is that there is no public API for single-page audits. You cannot programmatically send a URL and get a JSON response. Everything runs through the web dashboard or scheduled crawls.

2. What SEOPeek Does

SEOPeek is a single-purpose SEO audit API. You send it a URL via HTTP GET, it fetches the page, runs 20 on-page SEO checks, and returns a JSON response with a numeric score, a letter grade, and pass/fail details for each check—all in under 2 seconds.

The 20 checks cover the on-page factors with the most direct impact on search rankings:

• Title tag: existence, length, keyword placement
• Meta description: existence, length, uniqueness
• Heading structure: H1 presence, hierarchy, count
• Open Graph tags: og:title, og:description, og:image
• Canonical URL: presence and correctness
• Structured data: JSON-LD schema detection
• Image optimization: alt text coverage, image count
• Robots directives: meta robots, X-Robots-Tag
• Content quality: word count, internal/external link ratio
• Mobile readiness: viewport tag, font sizes

There is no dashboard, no crawl scheduler, no rank tracker. SEOPeek is infrastructure—a building block that developers wire into their own systems. You call it from CI/CD pipelines, cron-based monitoring scripts, client reporting tools, or custom dashboards. The API is the product.

The free tier gives you 50 audits per day with no API key required. Paid plans start at $9/month for 1,000 audits (Starter) and $29/month for 10,000 audits (Pro). There are no feature gates between tiers—every plan gets the same 20 checks, the same JSON response, the same sub-2-second speed.

3. Feature Comparison Table

Here is a side-by-side breakdown of the two tools across the dimensions that matter most for developers and SEO teams:

4. Pricing Comparison

Both tools target small-to-mid-market buyers, but they price for very different use cases. Sitechecker charges for site monitoring capacity (number of URLs in your projects). SEOPeek charges for API call volume.

The pricing reveals different product philosophies. Sitechecker charges based on how many websites and URLs you monitor through their dashboard. SEOPeek charges based on how many API calls you make. For a developer who needs to audit 1,000 arbitrary URLs per month via code, SEOPeek Starter at $9/month is the only option—Sitechecker does not expose this capability at any price point.

For a marketing manager who wants to monitor 5 client websites through a dashboard with email alerts, Sitechecker Standard at $59/month is purpose-built for that workflow. SEOPeek would require you to build the dashboard, alerting, and scheduling yourself.

5. When to Use Sitechecker Pro

Sitechecker Pro is the right choice when you need a visual monitoring dashboard for ongoing site health. Specifically, it makes sense when:

• Your team is non-technical. Marketing managers, content strategists, and SEO consultants who prefer visual reports and email alerts over JSON responses and terminal commands will find Sitechecker’s interface intuitive and actionable.
• You need full-site crawling. If your workflow involves crawling an entire site to find broken links, redirect chains, orphan pages, and internal linking issues, Sitechecker’s crawler handles this natively. SEOPeek audits one page at a time.
• You want rank tracking included. Sitechecker bundles keyword position monitoring, so you can see SEO health and ranking trends in one place. SEOPeek does not track rankings.
• You need change detection. Sitechecker alerts you when titles, descriptions, or robots tags change on your pages. This is valuable for catching unexpected CMS changes or third-party script interference.
• You manage a small number of client sites. For agencies monitoring 5–25 client websites through dashboards and PDF reports, Sitechecker’s project-based structure and white-label options are well-suited.
• You prefer scheduled monitoring over on-demand audits. Sitechecker runs on a schedule you configure. It does the work in the background and surfaces issues. You do not need to write code to trigger audits.

6. When to Use SEOPeek

SEOPeek is the right choice when you need programmatic, on-demand SEO audits via API. It was built for developers and DevOps teams, not marketing departments. SEOPeek makes sense when:

• You want SEO checks in CI/CD. Add a single curl command to your GitHub Actions, GitLab CI, or Jenkins pipeline. If the SEO score drops below your threshold, the build fails. No dashboard login required—just an HTTP request that returns JSON.
• You are building your own tools. Agencies and SaaS companies that build custom SEO dashboards, client reporting systems, or monitoring platforms need raw audit data via API. SEOPeek is the data layer; you build the interface.
• You need speed. Sitechecker crawls take minutes to hours. SEOPeek returns results in under 2 seconds. For pre-deploy checks, pull request previews, or real-time monitoring, sub-2-second latency is non-negotiable.
• You audit URLs programmatically. If you have a list of 500 URLs from a sitemap, a CMS export, or a database query and you want to audit all of them via script, SEOPeek’s API handles this cleanly. Sitechecker requires you to add sites manually through the dashboard.
• Your budget is under $30/month. SEOPeek’s free tier (50 audits/day) and $9/month Starter plan give you professional-grade SEO auditing without enterprise pricing. Solo developers, small startups, and side projects get real value at these price points.
• You do not need a dashboard. If you already have monitoring infrastructure (Grafana, Datadog, custom dashboards), you want data, not another platform to log into. SEOPeek gives you JSON you can pipe anywhere.

7. SEOPeek API: Real Code Example

Here is what it looks like to call the SEOPeek API, parse the response, and act on the results. No SDK, no account, no API key for the free tier—just a standard HTTP GET request.

Basic audit call (curl)

curl "https://us-central1-todd-agent-prod.cloudfunctions.net/seopeekApi/api/v1/audit?url=https://example.com"

Python: audit and alert on failures

import requests

SEOPEEK_API = "https://us-central1-todd-agent-prod.cloudfunctions.net/seopeekApi/api/v1/audit"

def audit_url(url: str) -> dict:
    """Audit a single URL and return the JSON result."""
    resp = requests.get(SEOPEEK_API, params={"url": url}, timeout=30)
    resp.raise_for_status()
    return resp.json()

result = audit_url("https://example.com")
print(f"Score: {result['score']}/100 ({result['grade']})")

# Find failing checks
failing = [
    (name, data["message"])
    for name, data in result.get("checks", {}).items()
    if not data["pass"]
]

if failing:
    print(f"\n{len(failing)} checks failed:")
    for name, message in failing:
        print(f"  - {name}: {message}")
else:
    print("All checks passed.")

GitHub Actions: SEO gate on every push

# .github/workflows/seo-check.yml
name: SEO Audit
on: [push]
jobs:
  seo:
    runs-on: ubuntu-latest
    steps:
      - name: Audit production URL
        run: |
          RESULT=$(curl -s "https://us-central1-todd-agent-prod.cloudfunctions.net/seopeekApi/api/v1/audit?url=https://yoursite.com")
          SCORE=$(echo "$RESULT" | jq '.score')
          echo "SEO Score: $SCORE"
          if [ "$SCORE" -lt 75 ]; then
            echo "FAIL: SEO score $SCORE is below threshold 75"
            echo "$RESULT" | jq '.checks | to_entries[] | select(.value.pass == false)'
            exit 1
          fi

The JSON response is designed for machine consumption:

{
  "url": "https://example.com",
  "score": 82,
  "grade": "B",
  "checks": {
    "title": {"pass": true, "message": "Title tag exists and is 52 characters"},
    "meta_description": {"pass": true, "message": "Meta description is 148 characters"},
    "h1": {"pass": true, "message": "Single H1 tag found"},
    "og_tags": {"pass": false, "message": "Missing og:image tag"},
    "canonical": {"pass": true, "message": "Canonical URL is set"},
    "structured_data": {"pass": false, "message": "No JSON-LD schema detected"},
    ...
  }
}

8. Using Both Together

Sitechecker Pro and SEOPeek solve different problems, which makes them natural complements:

• Sitechecker for the marketing team. Schedule weekly crawls, generate PDF reports for clients, track keyword rankings, and monitor backlinks. This is your visual, strategic SEO layer that non-technical stakeholders can access and understand.
• SEOPeek for the engineering team. Run on every deploy to catch on-page regressions before they hit production. Audit new content programmatically. Feed audit data into your internal Grafana dashboard. Gate pull requests on SEO score. This is your automated quality assurance layer.

The practical workflow: your SEO manager uses Sitechecker to identify that product pages need better structured data. Your engineering team fixes it. SEOPeek runs in CI/CD to make sure that structured data stays intact after every code change. Sitechecker tells you what to fix. SEOPeek makes sure it stays fixed.

Frequently Asked Questions

Does Sitechecker Pro have a public API for single-page audits?

No. Sitechecker Pro is a dashboard-first platform. It crawls entire websites on a schedule and presents results through its web interface. There is no public REST API for sending a single URL and getting a JSON audit response. If you need programmatic, on-demand audits, that is what SEOPeek was built for.

How much cheaper is SEOPeek compared to Sitechecker Pro?

SEOPeek Starter costs $9/month for 1,000 API audits. Sitechecker’s cheapest plan is $29/month for dashboard-based monitoring of one website. For developers who need an audit API, SEOPeek is roughly 3x cheaper at the entry level. And SEOPeek includes a free tier (50 audits/day) that has no equivalent in Sitechecker’s pricing.

Can I use SEOPeek in CI/CD pipelines as a Sitechecker alternative?

Yes, and this is one of the primary use cases SEOPeek was designed for. Add a curl command to your GitHub Actions workflow, GitLab CI pipeline, or Jenkins build step. If the SEO score drops below your threshold, fail the build. Sitechecker is not designed for CI/CD workflows—it is built around scheduled crawls and a web dashboard.

Is Sitechecker Pro better for ongoing site monitoring?

It depends on your team and workflow. Sitechecker excels at visual, dashboard-based monitoring for marketing teams. It crawls on a schedule, tracks changes, and sends email alerts. SEOPeek is better for programmatic monitoring: you write a script, call the API on a cron schedule, store results in your own database, and trigger alerts through your existing systems (Slack, PagerDuty, custom webhooks).

Can I use SEOPeek and Sitechecker Pro together?

Absolutely. Use Sitechecker for weekly full-site crawls visible to your marketing team and SEOPeek for real-time, per-page audits in your CI/CD pipeline and developer workflows. Sitechecker provides the big-picture dashboard. SEOPeek provides the automated API layer. They solve different problems for different teams.
