SEO Audit Tools Comparison showing Screaming Frog, Semrush, Ahrefs, and LLMFriendly features side by side
Back to Blog

Choosing the right SEO audit tool has never been more important—or more complex. With search evolving beyond traditional Google rankings to include AI platforms like ChatGPT and Gemini, today's brands need tools that can keep pace.

The market offers excellent options: Screaming Frog for deep technical analysis, Semrush for comprehensive SEO suites, Ahrefs for backlink-focused audits, and emerging solutions that integrate AI visibility tracking.

Each tool excels at different use cases. The question isn't "which tool is best?" but rather "which tool is best for your specific needs?"

In this guide, we'll compare the leading SEO audit tools on the market—including Screaming Frog, Semrush, Ahrefs, SE Ranking, and LLMFriendly—highlighting what each does well and who each solution best serves.

Whether you're a technical SEO professional, an agency managing multiple clients, or a brand focused on emerging AI platforms, this guide will help you find your ideal match.

How SEO Audit Needs Have Evolved in 2025

The SEO landscape continues to evolve rapidly. According to recent studies, over 60% of searches now involve AI-generated answers, and platforms like ChatGPT, Claude, and Gemini are becoming significant discovery channels for products and services.

This evolution means brands need to consider new factors when choosing an SEO audit tool:

1. Integration vs. Specialization

Different brands have different needs. Some benefit from specialized tools that excel at one thing (like Screaming Frog's deep technical crawling), while others prefer integrated platforms that combine auditing with rank tracking, competitor analysis, and AI visibility monitoring in one place.

2. Automation Capabilities

While manual audit tools offer granular control, many brands now need automated weekly scans to catch issues before they impact rankings. The right choice depends on whether you prioritize control or convenience.

3. AI Platform Visibility

Traditional SEO audit tools focus on Google optimization, which remains critical. However, brands appearing in ChatGPT, Claude, and Gemini results are gaining a competitive edge. Some brands need tools that track both traditional and AI visibility; others can succeed with separate solutions.

4. Deployment Model

Desktop tools like Screaming Frog offer power and affordability for technical professionals. Cloud-based solutions provide easier team collaboration and scheduled audits. The best choice depends on your team structure and workflows.

The key insight: There's no single "best" SEO audit tool—only the best tool for your specific situation. Let's explore what each leading solution offers.

Other Notable SEO Audit Tools

SE Ranking

Often cited as the best SEO audit tool for most users due to its balance of features and affordability. Starts at $65/month with comprehensive website audit capabilities. Still lacks AI visibility tracking.

Sitebulb

A powerful Screaming Frog alternative with beautiful visual reports and a "Hints" system that explains issues in plain English. Desktop and cloud versions available. Pricing starts at $35/month. No AI platform monitoring.

Lumar (formerly DeepCrawl)

Enterprise-grade cloud crawler designed for large websites. Excellent for technical SEO at scale but comes with enterprise pricing. No AI visibility features.

SEOptimer

Free website SEO checker that's great for quick audits. Limited depth compared to paid tools. No automation or AI tracking.

The pattern? Every traditional SEO audit tool operates in isolation from AI visibility. They all leave a critical gap in your monitoring stack.

Introducing LLMFriendly's Automated SEO Audit Dashboard

We built LLMFriendly.ai to solve a problem: brands were tracking AI visibility in one platform, traditional SEO in another, and competitor intelligence in a third. They couldn't see the connections between technical health and AI performance.

Today, we're introducing the Automated SEO Audit Dashboard—the first SEO audit tool that integrates directly with AI visibility tracking and competitive intelligence.

How It Works: 3-Step Automated Process

Step 1: Automated Page Discovery

Our crawler automatically discovers every page on your website. No manual URL entry. No sitemaps required. Just enter your domain and we'll find everything.

Step 2: Deep SEO Analysis (6 Categories)

Every week, we scan all your pages across 6 critical SEO categories:

  • Meta Tags & Descriptions - Missing titles, duplicate descriptions, header issues
  • Links & Structure - Broken links, redirect chains, site architecture problems
  • Performance & Speed - Page load times, image optimization, Core Web Vitals
  • Mobile Optimization - Responsiveness, mobile-specific SEO issues
  • Content Quality - Thin content, keyword optimization, readability scores
  • Technical SEO - Schema markup, canonical tags, sitemaps, robots.txt

Step 3: Actionable Recommendations

Get prioritized, step-by-step fixes for every issue. No raw data exports. No guesswork. Just clear instructions on what to fix and why it matters.

What Makes Our Audit Different

🤖 Integrated with AI Visibility Tracking

See how your technical SEO health correlates with your AI platform performance. When your ChatGPT ranking drops, check if a broken link or slow page is the culprit.

⚡ Weekly Automated Audits

No manual crawls. Every week, we automatically scan your site and alert you to new issues before they impact rankings.

🎯 Competitor Intelligence Integration

Your SEO audit lives alongside competitor tracking and citations monitoring. See the complete picture of your brand health in one dashboard.

📈 Unlimited Pages (Dominate Plan)

Scale from 500 pages (Optimize Plan) to unlimited pages (Dominate Plan) as your site grows. No per-page fees or crawl credit limits.

💰 Better Pricing Than Enterprise Tools

  • Optimize Plan: $89.99/month - 500 pages + AI visibility + competitor tracking
  • Dominate Plan: $129.99/month - Unlimited pages + AI visibility + competitor tracking

Compare that to Semrush's $499/month for 5,000 pages (without AI tracking) or Ahrefs' $499/month agency plan.

What Makes LLMFriendly Different: The Complete Brand Visibility Stack

Here's the fundamental difference: LLMFriendly isn't just an SEO audit tool. It's a complete brand visibility platform that shows you:

🔍 AI Rankings

Track your brand's visibility in ChatGPT, Claude, Gemini, and Perplexity. See exactly where you rank for buyer-intent queries across AI platforms.

🏆 Competitor Intelligence

Monitor competitor mentions alongside your own. See who's winning in AI platforms and traditional search—then learn from their strategy.

📰 Citations Monitoring

Discover which blogs, articles, and websites mention your brand vs. competitors. Find content gaps and build social proof.

🔧 Technical SEO Audits

Weekly automated scans across 6 categories. Fix broken links, optimize meta tags, improve page speed—all the foundational work that makes AI platforms trust your site.

The insight you can't get anywhere else:

When your ChatGPT ranking drops, you can check if a recent technical SEO issue is the cause. When a competitor suddenly appears in AI recommendations, you can see what citations they earned and what technical optimizations they made.

It's the only platform where SEO health + AI visibility + competitive intelligence live in one dashboard.

Frequently Asked Questions: SEO Audit Tools

What is the best free SEO audit tool?

Screaming Frog SEO Spider offers a free version for crawling up to 500 URLs, making it the most popular free SEO audit tool among professionals. For quick one-page audits, SEOptimer and Seobility offer free website SEO checkers. However, these free tools lack automation and AI visibility tracking—features you'll need for comprehensive brand monitoring.

Is Screaming Frog better than Semrush for SEO audits?

It depends on your needs. Screaming Frog excels at deep technical crawling and is more affordable for basic audits (£149/year vs. Semrush's $1,679/year minimum). However, Semrush offers automation, scheduled audits, and better reporting. For brands focused on AI visibility, neither tool provides ChatGPT or Gemini tracking—making LLMFriendly.ai a better choice for integrated monitoring.

How often should I run an SEO audit on my website?

Best practice is to run automated SEO audits weekly. Technical issues like broken links, slow pages, and missing meta tags can appear overnight and hurt your rankings immediately. Modern tools like LLMFriendly.ai, Semrush, and Ahrefs automate this process, scanning your site every week and alerting you to new problems before they impact visibility.

What should a good SEO audit tool check for?

A comprehensive SEO audit tool should check 6 core areas:

  1. Meta tags and descriptions (missing, duplicate, or incorrect)
  2. Links and site structure (broken links, redirect chains, architecture issues)
  3. Page speed and performance (load times, image optimization, Core Web Vitals)
  4. Mobile optimization (responsiveness, mobile-specific SEO)
  5. Content quality (thin content, keyword optimization, readability)
  6. Technical SEO (schema markup, canonical tags, sitemaps, robots.txt)

Why do I need both SEO audits and AI visibility tracking?

Technical SEO issues hurt your visibility everywhere—both in Google and AI platforms like ChatGPT. When you have broken links, slow pages, or missing structured data, AI systems struggle to understand and recommend your content. By tracking both in one platform, you can:

  • See correlations between technical issues and AI ranking drops
  • Fix problems that impact both traditional search and AI visibility
  • Save time by eliminating tool fragmentation
  • Get a complete picture of your brand health

What's the best Screaming Frog alternative for automated audits?

If you need automated weekly audits, consider Sitebulb (great UI, $35/mo), SE Ranking (best value, $65/mo), or LLMFriendly.ai ($89.99/mo with AI visibility tracking). For enterprise needs, Lumar (DeepCrawl) and Semrush offer powerful automation but at higher price points.

Can I use LLMFriendly for just SEO audits without AI tracking?

Yes! While LLMFriendly's strength is integrated AI visibility + SEO monitoring, you can absolutely use the SEO Audit Dashboard independently. That said, seeing both datasets together often reveals insights you'd miss with fragmented tools—like discovering that a technical SEO issue is preventing AI platforms from understanding your content.

Conclusion: Which SEO Audit Tool is Right for You in 2025?

Let's break it down:

Choose Screaming Frog if:

  • You're a technical SEO professional who needs deep crawl control
  • You're comfortable with desktop software and manual operation
  • You want the most affordable option for basic technical audits
  • You don't need automation or AI visibility tracking

Choose Semrush or Ahrefs if:

  • You have an enterprise budget ($140-500/month)
  • You need all-in-one SEO capabilities (rank tracking, backlinks, content, etc.)
  • You value automated audits and beautiful reporting
  • AI visibility isn't a priority (yet)

Choose SE Ranking if:

  • You want a balance of features and affordability
  • You need automated audits but have a limited budget
  • You're okay with separate tools for AI tracking

Choose LLMFriendly.ai if:

  • You're serious about AI visibility and need to track ChatGPT, Claude, and Gemini rankings
  • You want integrated monitoring that shows the connection between SEO health and AI performance
  • You need competitor intelligence alongside your technical audits
  • You want better value than enterprise tools—$89.99/mo for 500 pages or $129.99/mo for unlimited
  • You believe the future of search is AI-first, but technical SEO still matters

The Future is Integrated

The days of fragmented SEO tools are ending. Modern brands need platforms that show the complete picture: traditional search rankings + AI visibility + technical health + competitive intelligence.

You can keep using separate tools for each function—Screaming Frog for audits, Semrush for rankings, custom scripts for AI tracking. Or you can use one platform that brings it all together.

The choice is yours. But the brands that win in 2025 will be the ones that see the connections others miss.
