# Shipcheck > Check any page for SEO, WCAG 2.2 accessibility, AI search visibility, Core Web Vitals, and broken links. Free Chrome extension; Pro is $20 lifetime. Shipcheck is a Chrome extension for freelancers, indie hackers, and agencies. It checks the page in the active tab (including localhost, staging, and logged-in pages) and turns each issue into a plain-English fix and a copyable prompt for Cursor, Claude Code, or ChatGPT. The website also offers free browser-based tools that check any public URL. Key facts: - Price: core checks are free; Pro is a one-time $20 for lifetime access (no subscription). - Checks are rule-based. Page content is not sent to any large language model. - Accessibility audits use the open-source axe-core engine (WCAG 2.2 A/AA). Automated checks are an audit aid, not a legal certification. - Install: https://chromewebstore.google.com/detail/gigppmkcdifogcoeabmccdjmnhchcjmp - Built by Sumit Jha (https://peerlist.io/sumitjha).

In practice, websites and apps should meet WCAG 2.2 level AA (via EN 301 549). Micro-enterprises providing services (fewer than 10 employees and €2 million or less turnover) are exempt from the service requirements. - [Robots.txt for AI crawlers: get cited by ChatGPT, Perplexity, and Claude](https://shipcheck.site/guides/robots-txt-for-ai-crawlers): To appear in AI answers, allow the AI search crawlers (OAI-SearchBot for ChatGPT search, PerplexityBot, Claude-SearchBot) in robots.txt, even if you block training crawlers such as GPTBot and ClaudeBot. Make sure your content is in the server HTML, because most AI crawlers do not run JavaScript, and check that your CDN or firewall is not blocking them. - [Core Web Vitals fixes: LCP, CLS, and INP in plain English](https://shipcheck.site/guides/core-web-vitals-fixes): Google rates a page as good when Largest Contentful Paint is 2.5 seconds or less, Interaction to Next Paint is 200 milliseconds or less, and Cumulative Layout Shift is 0.1 or less, measured at the 75th percentile of real visits. Most fixes are simple: load the hero image early, reserve space for images and embeds, and break up long JavaScript tasks. - [Open Graph images and meta tags: sizes and tags for every platform](https://shipcheck.site/guides/open-graph-image-guide): Use a 1200×630 pixel PNG or JPG (1.91:1) with an absolute https URL in og:image, plus og:title, og:description, and twitter:card set to summary_large_image.

A short written report of what was checked and fixed sets expectations and makes the next project easier to win. - [How to get your website cited by ChatGPT, Perplexity, and Google AI Overviews](https://shipcheck.site/guides/how-to-get-cited-by-ai-search): AI search engines can only cite pages they can crawl, read, and trust. Allow the AI search crawlers in robots.txt, make sure your content is in the server-rendered HTML, get indexed by Google and Bing, put a direct answer near the top of each page, add structured data, and earn mentions on sites AI engines already cite, such as reviews, directories, Reddit, and roundups. - [What is llms.txt? Format, example, and whether you need one](https://shipcheck.site/guides/what-is-llms-txt): llms.txt is a Markdown file at the root of a website (/llms.txt) that gives AI assistants a short summary of the site and a curated list of links to its most useful pages. It was proposed by Jeremy Howard in September 2024. It is not an official standard and major AI search engines have not said they use it for ranking, but it is cheap to add and helps agents and developer tools that do read it. - [WCAG 2.2 checklist: every AA requirement in plain English](https://shipcheck.site/guides/wcag-2-2-checklist): WCAG 2.2 became a W3C Recommendation in October 2023. It has 55 success criteria at levels A and AA, including 6 new ones at those levels: Focus Not Obscured, Dragging Movements, Target Size (24×24 CSS pixels), Consistent Help, Redundant Entry, and Accessible Authentication. It removed 4.1.1 Parsing. Level AA is the usual target for the ADA, the European Accessibility Act, and most contracts. - [Launch checklist for AI-built sites (Lovable, Bolt, v0, Cursor, Replit)](https://shipcheck.site/guides/launch-checklist-for-ai-built-sites): AI app builders get a site working fast but often skip launch basics. Before you share the link, give every page its own title, description, and share image, make sure the content is in the server HTML (not only rendered by JavaScript), remove placeholder text and dead links, fix icon buttons without labels and low-contrast text, return a real 404, add security headers, and keep secret keys out of the browser. - [ADA website accessibility for small businesses: a practical guide](https://shipcheck.site/guides/ada-website-accessibility-small-business): The US Department of Justice has long said the ADA applies to the websites of businesses open to the public, and thousands of web accessibility lawsuits are filed each year. There is no ADA technical standard for private business websites, but WCAG 2.1 or 2.2 level AA is the benchmark used in settlements and in the 2024 DOJ rule for state and local governments. Fix issues in your code, test with a keyboard, and publish an accessibility statement. - [Best Chrome extensions for website QA in 2026: SEO, accessibility, and speed](https://shipcheck.site/guides/best-website-qa-chrome-extensions): For accessibility, WAVE and axe DevTools are the standard free checkers.
