A note on how to read this
This report is ProdPoke's take on your site — think of it as a first impression from a very opinionated robot. We check real things (load times, broken links, accessibility patterns), but we also try to understand what your site is trying to do and whether the technical details support that goal. Some of our observations might not apply to your specific situation, and that's okay. We're getting sharper with every scan. If something feels off, tell us — it makes us better.
Key Insights for Presentation Analyzer
CORS mismatch between Vercel and Clerk is blocking 100% of sign-in attempts.
Your frontend on presentation-analyzer-frontend.vercel.app cannot communicate with your Clerk auth service at exciting-bullfrog-35.accounts.dev due to missing CORS headers. Every user trying to access your presentation analyzer is stuck at the sign-in page.
A 2.6MB asset is adding 475ms to sign-in load time, killing first impressions.
Users waiting nearly half a second for your sign-in page to load—before they can even attempt authentication—will abandon the app. For a tool designed to save time analyzing presentations, slow auth is a credibility killer.
A mystery button on your sign-in page is invisible to screen readers.
One interactive element lacks an accessible name, preventing assistive technology users from understanding what action it triggers. This locks out users with disabilities from accessing your presentation analysis features entirely.
The 'Analyze' link on sign-in returns 404, so users can't reach the actual product.
This broken link suggests either a routing misconfiguration or missing fallback for unauthenticated users. If a visitor lands on the sign-in page and clicks to explore the analyzer, they hit a dead end instead of motivation to log in.
Three H1 tags on your auth page confuse search engines about what Presentation Analyzer does.
Search engines see conflicting signals about your page's primary topic, weakening SEO for branded searches. Users finding you via search won't get a clear preview of your presentation analysis capabilities.
What ProdPoke understands about Presentation Analyzer
Presentation Analyzer is an application that requires user authentication to access its core features. The sign-in page displays the heading 'Sign in to My Application' with a welcoming message 'Welcome back! Please sign in to continue,' indicating this is a returning user authentication interface. Users can sign in either through Google OAuth integration or by entering an email address and continuing with a password. The application is built on Vercel and uses Clerk for authentication security. Based on the URL path '/analyze' and the product name, it appears to be designed to help users analyze presentations, though the actual analysis features are protected behind authentication.

Overall Score
Strong foundation.
Performance
92/100Large asset: 2637KB — https://presentation-analyzer-frontend.vercel.app/_next/stat
A 2637KB asset (likely a logo or hero image) on your sign-in page is taking 475ms to load, slowing down authentication UX. Compress the image or lazy-load it to improve sign-in performance.
Found: 2637KB
SEO
72/100Missing Open Graph tags: og:title, og:description, og:image
Missing Open Graph tags mean when users share or log in through social platforms, no rich preview of your Presentation Analyzer application will appear. Add og:title, og:description, and og:image to improve how the app appears on social media.
Found: Missing: og:title, og:description, og:image
Multiple H1 tags (3)
Your sign-in page has 3 H1 tags instead of one. Multiple H1s confuse search engines about the primary purpose of your authentication page and weaken SEO signals for your Presentation Analyzer service.
Found: 3 H1 tags
Meta description too long (168 chars)
Your sign-in page's meta description (168 characters) will be truncated in search results and social shares. Trim it to under 160 characters to show the complete message welcoming returning users.
Found: 168 characters
No canonical URL specified
No canonical URL is specified for your sign-in page. If the sign-in page is accessible through multiple URLs (e.g., with different parameters), this could create duplicate content issues for search engines.
No robots.txt found
Missing robots.txt means search engines have no explicit guidelines for crawling your Presentation Analyzer site. Create one to manage how search engines access your public pages and authentication flows.
No sitemap.xml found
No sitemap.xml found. A sitemap would help search engines discover the sign-in page and any other publicly indexable pages of your Presentation Analyzer application.
Accessibility
92/1001 interactive element(s) without accessible names
An interactive element on your sign-in page lacks an accessible name (aria-label, title, or text content). Screen reader users cannot understand what this button or control does, creating a barrier to accessing your Presentation Analyzer.
Found: 1 missing: <button[type=submit].md:hidden>
Functional
92/100Dead link: HTTP 404 — Analyze
The 'Analyze' link on your sign-in page returns HTTP 404, meaning it points to a broken route. Users clicking this link cannot access the presentation analysis features they're trying to reach.
Found: HTTP 404
Technical Health
Access to fetch at 'https://exciting-bullfrog-35.accounts.dev/sign-in?redirec...
Your Clerk authentication service at exciting-bullfrog-35.accounts.dev is returning requests without proper CORS headers, blocking the sign-in redirect from your Vercel frontend. This prevents users from completing authentication to access the presentation analysis features.
Failed to load resource: net::ERR_FAILED
A network resource failed to load during the authentication handoff. This may prevent users from reaching the sign-in page or completing the login process needed to access your presentation analyzer.
Failed to fetch RSC payload for https://presentation-analyzer-frontend.vercel...
The Next.js React Server Component payload failed to fetch for the /analyze route. Users attempting to sign in and access your presentation analysis features will experience fallback behavior and potential navigation issues.
Network request failed: https://exciting-bullfrog-35.accounts.dev/sign-in?redirect_url=https%3A%2F%2Fpre
The authentication request to Clerk's sign-in endpoint is failing with a network error, preventing users from authenticating and accessing your presentation analyzer application.
CORS error detected
CORS policy is blocking requests between your Vercel frontend and Clerk's authentication service. Users cannot complete sign-in to access the protected presentation analysis features.
Compliance
99/1001 check passed
No privacy policy link found
No privacy policy link is visible on your sign-in page. Since you collect user data through Clerk authentication for your Presentation Analyzer, you should provide a privacy policy link to build user trust and meet legal compliance.

Improvement Plan
Your Presentation Analyzer has a critical infrastructure problem masking deeper UX issues. The CORS error between your Vercel frontend and Clerk authentication service is your immediate blocker—no user can sign in right now. Before investing time in SEO or accessibility fixes, work with your backend team to verify that the Clerk account configuration includes your Vercel domain in its allowed origins. This is a 15-minute fix that unblocks everything else.
Once authentication works, address the 2.6MB asset dragging down your sign-in performance. Compress that image aggressively (target under 400KB) or move it to lazy-load after the auth form renders. Users judge your app's polish in the first second—a slow sign-in page before they've even entered credentials signals poor engineering.
Next, fix the accessibility issue with the unnamed interactive element and the broken 'Analyze' link (404 error). The missing accessible name is a compliance risk if you process user data through Clerk. The dead 'Analyze' link may be intentional (protecting unauthenticated access), but if it's meant to educate visitors, route it to a feature overview or pricing page instead of a 404.
Finally, tackle the structural SEO problems: consolidate your three H1 tags into one, add a canonical URL to prevent duplicate content issues if the sign-in page is accessible via multiple redirect parameters, and add Open Graph tags so when users share the app link (or log in via Google), it shows a rich preview instead of a generic card. These fixes take 1-2 hours but significantly improve social credibility and search visibility.
Suggested priority order:
- CORS error detected: CORS policy is blocking requests between your Vercel frontend and Clerk's authentication service
- Network request failed: https://exciting-bullfrog-35.accounts.dev/sign-in?redirect_url authentication request to Clerk
- Large asset: 2637KB — https://presentation-analyzer-frontend.vercel.app/_next/stat image compression needed
- 1 interactive element(s) without accessible names: Screen reader accessibility barrier
- Dead link: HTTP 404 — Analyze link broken on sign-in page
- Multiple H1 tags (3): Consolidate to one primary heading
- Missing Open Graph tags: og:title, og:description, og:image
- Meta description too long (168 chars): Trim to under 160 characters
- No canonical URL specified: Add to sign-in page
- No privacy policy link found: Add link for legal compliance
