Here at KISS my SEO we are all about helping people demystify SEO. It doesn’t need to be a big scary term that just seems too hard. Just knowing a little can go a long way. We are always on the lookout for easy work arounds that people can implement – quickly. So we decided to go into the top three LLM’s and see what their response would be to do an SEO audit on your website and here are the answers.
Perplexity:
I can guide you through the process of performing an SEO audit and provide actionable steps, but I do not have the capability to directly crawl or analyse a website in real time. However, I can show you how to check which keywords are showing up for a site and offer practical suggestions to improve SEO using widely available tools and best practices.
How to See What Keywords a Site Ranks For
You can discover the keywords your website is ranking for using several free and paid SEO tools:
Google Search Console: Shows you which queries bring users to your site, along with impressions, clicks, and average position.
SEMrush, Ahrefs, Ubersuggest, or SE Ranking: Enter your domain to see a list of keywords your site ranks for, their positions, search volume, and estimated traffic.
Manual Check: View your website’s page source for meta keywords (if used), but note this is outdated and not recommended for modern SEO.
SEO Audit: What to Check
- Technical SEO
Check for broken links, slow page speeds, and mobile usability issues.
Use tools like Ahrefs, SEMrush, or SEOptimer to crawl your site and flag technical problems.
- On-Page SEO
Ensure each page has a unique, descriptive title and meta description.
Use relevant keywords naturally in headings, subheadings, and throughout the content.
Optimize images with descriptive file names and alt text.
- Content Quality
Publish relevant, authoritative, and up-to-date content.
Fill content gaps and update outdated articles.
Use a mix of head terms and long-tail keywords to reach a broader audience.
- Backlinks
Build links from reputable sites in your niche.
Remove or disavow toxic backlinks.
- User Experience
Ensure your website is easy to navigate.
Improve mobile responsiveness and page load times.

Response: I can help you with an SEO audit by analyzing a website’s content and structure, though I should clarify what I can and cannot do:
✅ What I can analyze:
- Page content, titles, headings, and meta descriptions
- Internal linking structure
- Basic technical SEO elements (HTML structure, alt text, etc.)
- Content quality and keyword usage
- Site organization and navigation
❌ What I cannot directly access:
- Current search rankings or what keywords the site actually ranks for
- Backlink profiles
- Search traffic data
- Server response times or Core Web Vitals
- Search Console or Analytics data
For keyword ranking data, you’d need to use tools like:
Google Search Console (free, shows actual search performance)
SEMrush, Ahrefs, or Moz (paid tools for comprehensive keyword tracking)
Google Keyword Planner for search volume data
How I can help:
If you provide me with a website URL, I can:
Analyze the visible content and structure
Identify potential SEO issues
Suggest improvements for titles, headings, and content
Recommend keyword optimization strategies
Check for basic technical SEO elements
Would you like me to audit a specific website for you? Just share the URL and I’ll provide a detailed analysis with actionable recommendations.
And finally the one that everyone seems to use
ChatGPT:
Response: Yes — I can absolutely help you perform an SEO audit, including:
✅ What I can do (with access or input):
Manual SEO Audit using public tools and website analysis:
On-page elements (title tags, meta descriptions, headers, image alt text)
Keyword density and relevance
Content structure, internal linking, and hierarchy
Site speed, mobile-friendliness, and accessibility
Indexability (robots.txt, sitemaps)
Basic backlink analysis (via tools or pasted data)
Semantic SEO and topical authority suggestions
Keyword Extraction + Ranking Suggestions:
I can extract visible keywords from any public page (home page, service pages, blog posts)
I’ll assess whether those keywords are actually strategic or just accidental.
I’ll suggest better-performing, relevant, or longer-tail keywords (based on user intent)
Suggestions to Improve SEO:
Content and copy suggestions to better target searcher intent
Meta title/description rewrites
Headline and structure improvements for readability + SEO
Image alt text improvements
Internal linking suggestions
Blog topic or content calendar ideas
❌ What I can’t do:
I can’t access private analytics (Google Search Console, Ahrefs, SEMrush, GA4) unless you paste exports or summaries here.
I can’t scrape keywords from competitors in real-time, but I can guide you to do it with free tools and interpret the results.
I can’t verify traffic or ranking positions directly — but I can show you how to track them using free tools like Google Search Console, Ubersuggest, or SERPRobot.
To Start Your Audit:
Please send me:
Your website URL
Any particular pages or services you want to rank higher
Your main target audience (industry, region, problem you’re solving)
Any specific competitors you want to outperform (URLs or names)
If you’re targeting local SEO or national/global reach
Once I have that, I’ll break it down:
🔍 What’s currently showing up (actual page analysis)
📉 What’s weak or missing
📈 Specific keyword and content strategy to improve it
🔍 Final Takeaway
We put three of the top AI tools to the test — Claude, ChatGPT, and Perplexity — to see how they stack up for a DIY SEO audit. The verdict? Claude stood out for clarity and actionability, ChatGPT brought solid suggestions and flexibility, and Perplexity offered a solid roadmap but lacked real-time analysis.
No AI tool replaces expert insight, but if you know what you’re looking for, these can seriously fast-track your SEO wins. Whether you’re just starting out or tightening things up, don’t overthink it — pick a tool, follow the steps, and make steady improvements.
