Common problems with v0 sites — and how to fix them

AI-built sites can look ready before Google, buyers and assistive technology see enough evidence to trust them. Use this page as a practical launch-pass for v0 sites.

Common issue

Google sees weak or repeated titles and meta descriptions

Read the metadata and title-tag deep dive

What it looks like

The homepage looks fine in the browser, but search results show a vague title, a missing description, repeated page names, or social previews that do not match the page.

Why it happens on v0

v0 is strong at generating React and Next-style UI, but page metadata, crawlable content and production deployment settings still need deliberate review. On v0, visible copy and SEO metadata are not the same job: each public route still needs its own title, description, canonical URL and Open Graph fields.

Copy-paste fix prompt

Audit my v0 site for search metadata problems. Work in the generated app routes, metadata exports, components and deployment configuration. Keep the current design and URLs. For every public page, add a unique title tag, H1, meta description, canonical URL, og:title, og:description and og:url. Make sure crawlers can see the final metadata in the served page. Return the exact files or settings changed and list the final metadata for each page.

Common issue

Duplicate host, protocol or slash versions split the same page

Read the duplicate-URL deep dive

What it looks like

The same page loads at more than one URL, such as www and non-www, http and https, or both trailing-slash and non-trailing-slash versions.

Why it happens on v0

v0 is strong at generating React and Next-style UI, but page metadata, crawlable content and production deployment settings still need deliberate review. v0 can publish quickly, but canonical host and redirect decisions usually happen outside the page design itself.

Copy-paste fix prompt

Fix URL canonicalisation for my v0 site. Work in the generated app routes, metadata exports, components and deployment configuration. Pick one canonical host and HTTPS format. Add single-hop 301 redirects from every non-canonical host, protocol and trailing-slash variant to the canonical URL. Update internal links, sitemap URLs, canonical tags and og:url values so they all match. Do not change page slugs or visible content.

Common issue

Large images and bundles make the site feel slower than it looks

Read the AI-built speed deep dive

What it looks like

The hero looks sharp on desktop, but mobile visitors wait on oversized images, heavy scripts, animations or layout shifts before the page becomes usable.

Why it happens on v0

v0 is strong at generating React and Next-style UI, but page metadata, crawlable content and production deployment settings still need deliberate review. v0 can make visual iteration feel cheap, so generated images, uploaded assets and extra components can accumulate without a performance pass.

Copy-paste fix prompt

Speed-audit my v0 site without redesigning it. Work in the generated app routes, metadata exports, components and deployment configuration. Find oversized images, uncompressed media, render-blocking scripts, unused heavy components and layout shifts. Resize and compress images, set explicit width and height, lazy-load below-the-fold media, and remove or defer anything not needed for the first screen. Keep the visual intent intact and list every asset changed.

Common issue

The copy sounds polished but could describe almost any business

Read the generic-copy deep dive

What it looks like

The page uses smooth phrases like seamless, innovative, transform, unlock or elevate, but gives few concrete details about the customer, problem, method or proof.

Why it happens on v0

v0 is strong at generating React and Next-style UI, but page metadata, crawlable content and production deployment settings still need deliberate review. v0 can generate fluent placeholder copy faster than a founder can supply real positioning, proof and constraints.

Copy-paste fix prompt

Rewrite the generic copy on my v0 site. Work in the generated app routes, metadata exports, components and deployment configuration. Keep the offer and layout, but replace vague AI-sounding claims with specific details: who this is for, the painful problem, what we actually do, what makes the method credible, what happens next, and what proof we genuinely have. Do not invent numbers, testimonials, client names, awards or case-study results.

Common issue

Trust pages and business details are missing or buried

Read the trust-signals deep dive

What it looks like

The site asks visitors to book, buy or submit a form before it has made the business easy to verify with contact details, policies, ownership cues or clear footer links.

Why it happens on v0

v0 is strong at generating React and Next-style UI, but page metadata, crawlable content and production deployment settings still need deliberate review. v0 focuses on generating the page experience; trust details usually come from the real business owner after the first draft.

Copy-paste fix prompt

Add trust basics to my v0 site. Work in the generated app routes, metadata exports, components and deployment configuration. Add or improve visible contact details, privacy policy, terms, cookie information where needed, footer links, organization schema and a short about/editorial note that matches the real business. Do not invent offices, certifications, awards, press, customers or results. Keep the additions concise and easy to find.

Common issue

Generated UI components fail accessibility basics

Read the accessibility deep dive

What it looks like

Buttons have unclear names, form fields lack labels, headings skip levels, text contrast is low, images miss useful alt text, or keyboard focus gets lost.

Why it happens on v0

v0 is strong at generating React and Next-style UI, but page metadata, crawlable content and production deployment settings still need deliberate review. v0 can generate attractive components, but accessibility depends on semantic labels, keyboard states and content-specific alt text that need a review pass.

Copy-paste fix prompt

Run an accessibility cleanup on my v0 site. Work in the generated app routes, metadata exports, components and deployment configuration. Fix missing form labels, ambiguous button names, heading order, image alt text, low contrast, keyboard focus states and interactive elements that cannot be reached or understood without a mouse. Keep the visual style close to the current design and list each issue fixed.

FAQ

Questions people ask about v0 sites

What are the most common problems with v0 sites?

v0 sites most often need a post-launch pass for search metadata, canonical URLs, image weight, specific copy, trust details and accessibility basics. The visible page can look finished while those launch checks are still incomplete.

Can v0 sites rank on Google?

Yes. A site built with v0 can be indexed and ranked if Google can crawl useful content, each page has clear metadata, duplicate URL versions are controlled, and the site earns trust with specific copy and real business details.

Should I rebuild my v0 site to fix these issues?

Usually no. Start with the practical fixes: metadata, canonical redirects, image optimisation, trust pages, copy specificity and accessibility. Rebuild only if the current site cannot expose crawlable content or support the required settings.

How do I know which v0 fixes matter first?

Run a scan, check the weakest categories, and fix the problems that block discovery, trust or action before polishing lower-impact details.
