Website Audit for a Site Built with Cursor: What to Check Before You Launch
Cursor AI builds websites fast, but speed creates SEO blind spots. A practical audit checklist for Cursor-built sites covering performance and rankings.
# Website Audit for a Site Built with Cursor: What to Check Before You Launch
Cursor has changed how people build websites. You describe what you want, the AI writes the code, and within hours you have a functional site. For small business owners who never planned to learn React or Next.js, that's genuinely powerful.
But there's a catch. Cursor is excellent at generating code that works. It's less reliable at generating code that ranks, loads fast on mobile, or converts visitors into customers. The gap between "my site is live" and "my site is actually performing" is where most Cursor-built websites stall.
This guide walks through the specific issues that show up in Cursor-built sites and how to find and fix them before they cost you traffic and revenue.

Why Cursor-Built Sites Need a Different Kind of Audit
Traditional website builders like Squarespace or Wix handle SEO basics automatically. They generate sitemaps, add meta tags through form fields, and compress images on upload. You don't think about these things because the platform handles them.
Cursor doesn't work that way. It generates raw code — usually React or Next.js — and that code does exactly what you asked for, nothing more. If you didn't mention meta descriptions in your prompt, you won't have meta descriptions. If you didn't ask for image optimization, your 4MB hero image ships as-is.
This isn't a flaw in Cursor. It's the nature of code generation versus managed platforms. But it means the audit checklist for a Cursor-built site looks different from what you'd run on a Squarespace or Wix site.
The Seven Most Common Issues in Cursor-Built Sites
1. Missing or Duplicate Meta Tags
This is the single most common problem. Cursor generates attractive page layouts but frequently skips the invisible SEO layer — title tags, meta descriptions, Open Graph tags, and canonical URLs.
What to check:
- Does every page have a unique
tag under 60 characters? - Does every page have a unique meta description between 120–160 characters?
- Are Open Graph tags present for social sharing?
- Is there a canonical URL on each page?
When Cursor generates a multi-page site, it often reuses the same generic title across pages or leaves the default "Create Next App" title in place. Google treats duplicate titles as a signal that pages aren't distinct, which hurts rankings across the board.
Quick test: Right-click any page, select "View Page Source," and search for . If you see the same text on multiple pages — or something generic like "Vite App" — that needs fixing immediately.
2. Client-Side Rendering Without Server-Side Fallbacks
Cursor defaults to React components that render in the browser. This creates a real problem for SEO: Google's crawler may see an empty page until JavaScript executes.
Google has improved at rendering JavaScript, but it's not instant or guaranteed. Google's documentation on creating helpful content emphasizes that pages need to deliver core content reliably. A page that depends entirely on client-side JavaScript is inherently less reliable than one that sends complete HTML from the server.
What to check:
- View your page source (not the browser inspector — the actual source). Do you see your text content in the HTML, or just a
with script tags? - If you're using Next.js, are your pages using Server Components or static generation, or are they purely client-rendered with
"use client"on every file? - Does your content appear when JavaScript is disabled?
If your page source is mostly empty, search engines may not index your content properly.
3. Unoptimized Images
Cursor will add images to your site using whatever format and size you provide. It rarely converts images to WebP, adds width/height attributes, implements lazy loading, or generates responsive srcset attributes.
For a small business site, images are often the biggest performance bottleneck. A single unoptimized hero image can add 3–5 seconds to your load time on mobile.
What to check:
- Are images in WebP or AVIF format (not PNG or full-size JPEG)?
- Do
tags includewidthandheightattributes? - Are below-the-fold images lazy-loaded?
- Is there a responsive image strategy using
srcset?
Real example: A landscaping company had Cursor build their portfolio page. Each project photo was a 3000×2000 pixel JPEG averaging 2.5MB. The page had 12 photos — over 30MB total. On a mobile connection, the page took 18 seconds to load. After converting to WebP with proper sizing, page weight dropped to 1.8MB and load time fell under 3 seconds.

4. No Structured Data
Structured data — the JSON-LD markup that tells Google what your business is, where it's located, and what services you offer — almost never appears in Cursor-generated sites unless you specifically request it.
This matters because structured data powers rich results in Google Search. A local business with proper LocalBusiness schema can show hours, ratings, and location directly in search results. Without it, you're just a plain blue link competing against rich listings.
Google's structured data documentation for articles notes that proper markup helps Google understand and display your content in enhanced search features. The same applies to business and product schemas.
What to check:
- Does your site include JSON-LD structured data on key pages?
- Is
LocalBusinessorOrganizationschema present on your homepage? - Do blog posts include
Articleschema? - Does your structured data pass Google's Rich Results Test?
5. Missing Accessibility Basics
Cursor generates code that looks right visually but often skips accessibility fundamentals: missing alt text on images, broken heading hierarchy (jumping from H1 to H4), missing form labels, and low color contrast.
Beyond being the right thing to do, accessibility issues directly impact SEO. Google uses heading structure to understand page hierarchy. Missing alt text means Google can't interpret your images. Poor contrast increases bounce rates.
Quick checklist:
- [ ] Every image has descriptive alt text
- [ ] Heading hierarchy is sequential (H1 → H2 → H3, no skipping)
- [ ] All form inputs have associated labels
- [ ] Color contrast ratios meet WCAG AA standards (4.5:1 for text)
- [ ] Interactive elements are keyboard-accessible
6. No Sitemap or Robots.txt
A sitemap tells search engines which pages to crawl. A robots.txt file gives crawling instructions. Most Cursor-built sites have neither.
Without a sitemap, Google still discovers pages through links, but it's slower and less reliable — especially for new sites with no backlinks. For a small business that needs to start ranking quickly, every delay matters.
What to check:
- Does
yoursite.com/sitemap.xmlreturn a valid XML sitemap? - Does
yoursite.com/robots.txtexist and reference your sitemap? - Are all important pages included in the sitemap?
- Are utility pages (login, admin, thank-you pages) excluded?
7. Core Web Vitals Failures
Google's Core Web Vitals — Largest Contentful Paint (LCP), Interaction to Next Paint (INP), and Cumulative Layout Shift (CLS) — are ranking factors. Cursor-built sites frequently struggle with all three.
Common causes in Cursor-generated code:
- LCP issues: Unoptimized hero images, render-blocking JavaScript, no font preloading
- INP issues: Heavy client-side processing, unoptimized event handlers, excessive re-renders
- CLS issues: Images without dimensions, dynamically injected content, late-loading fonts that shift text
According to web.dev's Core Web Vitals documentation, good thresholds are: LCP under 2.5 seconds, INP under 200 milliseconds, and CLS under 0.1.
How to Audit Your Cursor-Built Site Step by Step
Step 1: Run an Automated Audit
Start with a comprehensive scan. Run a free audit on FreeSiteAudit to get a baseline report covering SEO, performance, accessibility, and technical issues. This gives you a prioritized list instead of hunting for problems one by one.
The report flags the specific issues described above — missing meta tags, image problems, Core Web Vitals failures, missing structured data — ranked by impact on your search visibility.

Step 2: Fix High-Impact SEO Issues First
Based on your audit results, tackle issues in this order:
Priority 1 — Foundational (fix today):
- Add unique title tags and meta descriptions to every page
- Ensure content renders server-side, not just client-side
- Add a sitemap.xml and robots.txt
- Fix any broken links or 404 errors
Priority 2 — Performance (fix this week):
- Convert all images to WebP with proper dimensions
- Add width/height attributes to prevent layout shift
- Implement lazy loading for below-the-fold images
- Remove unused CSS and JavaScript
Priority 3 — Enhancement (fix this month):
- Add structured data (LocalBusiness, Article, FAQ schemas)
- Fix accessibility issues (alt text, heading hierarchy, contrast)
- Add Open Graph tags for social sharing
- Implement proper internal linking
Step 3: Use Cursor to Fix What Cursor Missed
Here's the good news: you can use Cursor itself to fix most of these issues. The key is writing specific prompts rather than vague requests.
Instead of: "Make my site SEO-friendly"
Try: "Add unique meta title and description tags to each page. The homepage title should be '[Your Business] — [Your Service] in [Your City]' and the description should summarize our main service in 150 characters. Add JSON-LD LocalBusiness structured data to the homepage with our business name, address, phone, and hours."
For image optimization: "Convert all images to use Next.js Image component with WebP format, add width and height props, implement lazy loading for images below the fold, and set priority loading on the hero image."
Treat each audit finding as a specific prompt. The more precise your instructions, the better Cursor performs.
Step 4: Re-Audit After Fixes
After making changes, run another audit to verify the fixes worked and didn't introduce new issues. It's common for one fix to create another problem — for example, adding lazy loading to your hero image can actually hurt LCP if that image is above the fold and should load eagerly.
Real-World Example: Local Bakery Site
Sarah owns a bakery in Portland. She used Cursor to build her website in an afternoon — beautiful photos, clear menu, online ordering form. After two months, she's getting almost no organic traffic from Google.
Initial audit findings:
- Title tag on every page: "My Bakery App" (the Cursor default)
- No meta descriptions on any page
- 24 product photos as full-resolution PNGs (average 3.1MB each)
- Entire site renders client-side only
- No sitemap.xml or robots.txt
- No structured data
- Lighthouse performance score: 23/100
- Three broken links to removed pages
After fixes (using Cursor with specific prompts):
- Unique titles: "Sarah's Bakery Portland — Fresh Sourdough & Pastries" (homepage), "Our Menu — Sarah's Bakery Portland" (menu page), etc.
- Meta descriptions written for each page
- All images converted to WebP, resized to max 1200px wide, lazy-loaded below the fold
- Pages converted to server-side rendering
- Sitemap and robots.txt generated
- LocalBusiness and Menu structured data added
- Lighthouse performance score: 91/100
- All broken links fixed or redirected
Result after 6 weeks: Sarah's site appeared in local search results for "bakery Portland," "sourdough bread Portland," and "pastries near me." The structured data enabled a rich result showing her hours and rating. Mobile visitors stopped bouncing because pages loaded in under 2 seconds instead of 12.
None of the fixes required learning to code. Each one was a specific prompt fed back into Cursor.
