ePageUSA vs SEOptimer vs Sitechecker: Which SEO Audit Tool Is Best?

SEO audit tools all promise the same thing: scan your site, find problems, tell you how to fix them. But the experience — and the price — varies wildly. Some give you everything for free. Others show you a preview and lock the rest behind a $20-50/month paywall.

We put three popular SEO audit tools through the same test to see which one delivers the most actionable insights without draining your wallet.

The Contenders

ePageUSA Site Analyzer — An all-in-one website intelligence tool that combines SEO auditing with tech stack detection, visual design inspection, security analysis, and more. Completely free.

SEOptimer — A dedicated SEO audit tool that grades websites on SEO, usability, performance, social presence, and security. Free report available.

Sitechecker — An SEO platform that crawls your site for technical SEO issues, tracks rankings, and monitors backlinks. Free tier available.

SEO Auditing

All three tools check the fundamentals: title tags, meta descriptions, headings, image alt text, mobile optimization, and page speed.

ePageUSA runs 12 specific checks and gives you an A-F letter grade. Each check shows pass/warning/fail with the actual value found and a recommendation. It's designed to be understandable by non-technical business owners.

SEOptimer provides a more traditional SEO report with a 0-100 score across multiple categories. The report is detailed and well-designed. However, the free version gives you one report — after that, you need a plan starting at $19/month.

Sitechecker goes deeper with full-site crawling (not just single-page analysis). It finds issues like broken links, duplicate content, and crawl errors across your entire site. But the free tier is extremely limited — a few pages only.

What Sets Them Apart

ePageUSA goes way beyond SEO

The biggest differentiator is scope. ePageUSA isn't just an SEO tool — it's a complete website intelligence platform. One scan gives you:

• SEO audit with grade
• Tech stack identification (what frameworks, CMS, analytics the site uses)
• Font detection with live previews
• Color palette extraction with hex codes
• Image gallery with alt text audit
• Social media preview cards
• Security header analysis
• Accessibility checks
• Performance metrics
• Link analysis

Neither SEOptimer nor Sitechecker offers visual design inspection, font detection, or tech stack analysis.

SEOptimer excels at readability

SEOptimer's reports are clean, well-organized, and easy to understand. They're designed to be shared with clients — which is why they're popular with agencies. The white-label report feature (paid) is a genuine differentiator for agencies.

Sitechecker wins on crawling

If you need to audit an entire site with hundreds of pages, Sitechecker's crawler is the right tool. It finds issues that single-page tools miss: orphan pages, redirect chains, duplicate content across pages.

Pricing Reality Check

ePageUSA: Free. No limits. No signup. No catch.

SEOptimer: First report is free. After that:

• DIY SEO: $19/month
• White Label: $29/month
• White Label & Embedding: $59/month

Sitechecker: Limited free tier, then:

• Basic: $29/month
• Standard: $69/month
• Premium: $139/month

When to Use Each

Use ePageUSA if: You want a complete picture of any website in one scan — SEO, design, tech, security, everything. Best for business owners, designers, and marketers who need actionable insights without paying for multiple tools.

Use SEOptimer if: You're an agency that needs white-label SEO reports for clients. The branded report feature is worth the price for that specific use case.

Use Sitechecker if: You're an SEO professional who needs full-site crawling, rank tracking, and backlink monitoring across client sites. The platform is built for ongoing SEO management, not one-time audits.

The Bottom Line

For quick, comprehensive website analysis, the ePageUSA Site Analyzer gives you the most value for free — not just SEO, but everything you'd want to know about a website. SEOptimer and Sitechecker are solid tools, but their free tiers are essentially demos for paid products.
