Add a canonical link No <link rel="canonical"> was detected on your page.

1 more score-affecting fix below, plus advisory items.

Fixes that improve your score

Discoverability

MEDIUMAdd a robots.txt file
WhyTells search engines and bots which pages to crawl and which to skip. Without one, crawlers default to indexing everything they can reach, including admin paths and staging URLs.
WhereCreate /robots.txt at the site root. Most frameworks have a built-in path (Next.js app/robots.ts, Astro public/robots.txt).
Learn more
MEDIUMAdd a sitemap.xml
WhyHelps search engines discover all your pages, including deep-linked ones not in the navigation. Without one, only pages reachable via crawl-from-homepage get found.
WhereGenerate /sitemap.xml and reference it from robots.txt with a Sitemap: line. Frameworks usually generate it (Next.js app/sitemap.ts, Astro @astrojs/sitemap).

Page basics & SEO

MEDIUMAdd a canonical link
No <link rel="canonical"> was detected on your page.
WhyTells search engines which URL is the canonical version when the same content is reachable via multiple paths (with/without trailing slash, query strings, www vs apex).
WhereAdd <link rel="canonical" href="https://your-domain.com/this-page"> to each page's <head>.
Learn more
MEDIUMAdd Twitter card meta tags
No Twitter card tags were detected on your page.
WhyWithout them, links shared on X render as bare text instead of a rich preview card with image, title, and description. Rich cards have meaningfully higher CTR.
WhereAdd <meta name="twitter:card" content="summary_large_image">, plus twitter:title, twitter:description, and twitter:image to your <head>.
Learn more

Optional improvements

These don't change your StackScope score but cover SEO, agent-readiness, security-researcher discoverability, and compliance items worth addressing.

Security

LOWAdd /.well-known/security.txt
WhyLets security researchers report vulnerabilities responsibly through a published contact channel.
WhereCreate /.well-known/security.txt with a Contact: email and Expires: date.
Learn more

Legal & compliance

HIGHAdd a cookie-consent banner
Analytics detected on this site without a consent manager.
WhyUK/EU GDPR requires opt-in before analytics scripts fire; about half of US state privacy laws now require honouring the Global Privacy Control browser signal as a universal opt-out.
WhereDrop in Cookiebot, Usercentrics, Osano, or Iubenda Consent, or hand-roll a banner plus Google's Consent Mode v2.
Learn more
Why this matters & sources
The legal landscape: UK/EU GDPR treats analytics as personal-data processing that requires opt-in consent before scripts fire. About half the US state privacy laws now in force (California, Colorado, Texas, Connecticut, Oregon, Montana, Delaware, New Hampshire, New Jersey, Nebraska) require honouring the Global Privacy Control (GPC) browser signal as a universal opt-out, and California's January 2026 regulations require visibly indicating when a GPC signal has been honoured.
Sources: IAPP US state privacy tracker (iapp.org/resources/article/us-state-privacy-legislation-tracker), California AG on GPC (oag.ca.gov/privacy/ccpa/gpc), EDPB consent guidelines (edpb.europa.eu).

Email security

MEDIUMMove DMARC from p=none to quarantine or reject
DMARC policy is p=none (monitoring only).
Whyp=none lets receivers log failures but still deliver spoofed mail. Real protection only kicks in at quarantine or reject.
WhereAfter reviewing a few weeks of rua= reports and confirming your real senders pass, change to p=quarantine (sends spoofs to spam) and then p=reject (blocks them outright).
Learn more
MEDIUMConfigure DKIM with your email provider
No DKIM record found at the common selectors we check.
WhyDKIM signs your outbound mail with a cryptographic key receivers can verify. Without it, receivers can't tell your real mail from a spoof.
WhereAsk your email provider for their DKIM setup. It's usually one TXT record at {selector}._domainkey.{your-domain}.
Learn more
Why this matters & sources
Selectors we probe: Resend, SendGrid, Postmark, Mailchimp, Brevo, Mailgun, HubSpot, Customer.io, ConvertKit, Cloudflare Email. If you use Google Workspace, Microsoft 365, or self-hosted email with a custom selector, you may already have DKIM published and we just don't see it.
LOWAdd MTA-STS
No MTA-STS DNS record published.
WhyPrevents mail to your domain being downgraded to plaintext mid-flight by a network attacker. Most launches don't have this, so deploying it puts you a tier above generic email-security checks.
WherePublish a TXT record at _mta-sts.{your-domain} plus a policy file at https://mta-sts.{your-domain}/.well-known/mta-sts.txt.
Learn more
LOWAdd a TLS-RPT record
No TLS-RPT record at _smtp._tls.{domain}.
WhyReceivers can tell you when STARTTLS handshakes to your mail server fail. Without it, silent TLS failures are invisible.
WherePublish one TXT record at _smtp._tls.{your-domain} like v=TLSRPTv1; rua=mailto:[email protected].
Learn more

Page basics & SEO

LOWTrim your <title> tag to under 60 characters
Currently 64 characters: "Upgrade: Stop Juggling 5 Apps. Run Your Business From One Place."
WhyGoogle truncates titles around 60 characters in search results, so anything past that gets cut off mid-sentence and costs click-through rate.
WhereAim for 50-60 characters that include your main keyword and brand.
Learn more
LOWTrim your meta description to under 160 characters
Currently 207 characters: "12 modules. Track income, clients, habits, tasks, pipeline, retainers. Sign in once with your purchase email, then works without internet. Your data never leaves your browser. No subscription. $199 one-time."
WhyGoogle truncates around 155-160 characters on desktop SERPs (less on mobile), so anything past that won't appear in the snippet.
WhereEdit your <meta name="description"> tag. Put the most click-worthy phrase first.
Learn more

Performance

MEDIUMSet width and height on your images
1 image render without explicit width/height.
WhyWithout intrinsic dimensions the browser can't reserve space before the image loads, so content jumps as it arrives (cumulative layout shift).
WhereAdd width and height attributes (or an aspect-ratio CSS rule). Framework image components set these for you.
Learn more

Agent / AI

LOWAdd an llms.txt file
WhyHelps AI models understand your site's content and how to use it. Not yet a standard but gaining adoption.
WhereCreate /llms.txt at the site root with a brief overview and key URLs.
Learn more
LOWDeclare a Content-Signal in robots.txt
WhyStates how you'd like AI systems to use your content (training, search, agent input). Without it, AI crawlers fall back to whatever default policy each vendor applies.
WhereAdd a Content-Signal: line to your robots.txt.
Learn more
LOWAdd Link response headers
WhyLets agents discover your sitemap, privacy policy, and docs without parsing HTML, which most lightweight agents skip.
WhereSet Link: response headers in your server config or framework middleware.

If a tip looks wrong (for example it says "add a consent banner" and you already have one) the detection's the bug, not you. StackScope sees what's public from the outside: HTTP response, rendered HTML, cookies, and DNS. We can miss vendors that load behind consent, are self-hosted, or use an install shape we haven't fingerprinted yet. Email [email protected] and we'll look into it.

Copy into Cursor, Claude, or ChatGPT

This prompt includes the detected stack and only the fixes StackScope found. It asks the AI to make concrete file-level changes, not a vague website review.

Score-affecting basics only. Ask your AI to handle these first; come back for the optional hardening once they're done.

Everything: score-affecting fixes plus optional email security, agent metadata, and best-practice items. Longer prompt, more for an "all in one" agent run.

I own https://upgrade.mockupshelf.com. StackScope (https://stackscope.dev) analysed it on 4 June 2026 and scored it 6.4/10 against their production-readiness checklist. Please help me apply the fixes below. These are the score-affecting basics. We'll circle back to the optional hardening (email security, advanced agent metadata) later.

Tech stack StackScope detected on the site (use this when suggesting where each fix lives in the codebase):
facebook, facebook-pixel, google-analytics, google-fonts, google-tag-manager, hostinger, hsts, http3, razorpay

Score-affecting fixes (these improve the StackScope score; [HIGH] = most impact):
- [MEDIUM] Add a robots.txt file. Why: Tells search engines and bots which pages to crawl and which to skip. Without one, crawlers default to indexing everything they can reach, including admin paths and staging URLs. Where: Create `/robots.txt` at the site root. Most frameworks have a built-in path (Next.js `app/robots.ts`, Astro `public/robots.txt`). (https://developers.google.com/search/docs/crawling-indexing/robots/intro)
- [MEDIUM] Add a sitemap.xml. Why: Helps search engines discover all your pages, including deep-linked ones not in the navigation. Without one, only pages reachable via crawl-from-homepage get found. Where: Generate `/sitemap.xml` and reference it from `robots.txt` with a `Sitemap:` line. Frameworks usually generate it (Next.js `app/sitemap.ts`, Astro `@astrojs/sitemap`). (https://developers.google.com/search/docs/crawling-indexing/sitemaps/overview)
- [MEDIUM] Add a canonical link. No `<link rel="canonical">` was detected on your page. Why: Tells search engines which URL is the canonical version when the same content is reachable via multiple paths (with/without trailing slash, query strings, www vs apex). Where: Add `<link rel="canonical" href="https://your-domain.com/this-page">` to each page's `<head>`. (https://developers.google.com/search/docs/crawling-indexing/consolidate-duplicate-urls)
- [MEDIUM] Add Twitter card meta tags. No Twitter card tags were detected on your page. Why: Without them, links shared on X render as bare text instead of a rich preview card with image, title, and description. Rich cards have meaningfully higher CTR. Where: Add `<meta name="twitter:card" content="summary_large_image">`, plus `twitter:title`, `twitter:description`, and `twitter:image` to your `<head>`. (https://developer.mozilla.org/en-US/docs/Web/HTML/Element/meta/name)

For each item, tell me exactly which file to create or which code to change, and where it lives in a project using the stack above. If my framework has a native API for the task (e.g. Next.js metadata exports, `app/sitemap.ts`, Astro layouts, Nuxt `useHead`), prefer that over raw HTML or server config.

Using an autonomous agent?

Point the agent at this SKILL.md URL and ask it to follow the skill. The framing stops agents defaulting to an open-ended page review.

Using a Content-Security-Policy? Both badges are <img> tags from our domain, so your CSP needs to allow them. Add stackscope.dev to your img-src directive (example: img-src 'self' stackscope.dev;). Without it, browsers silently block the badge and visitors see a broken image.
