Audit the titles, descriptions, images, and URLs shown when web pages are shared on social networks or messaging apps. Check Open Graph metadata, the tags that define link previews, for missing values and incorrect settings.
Audit paginated archives, product lists, and search results. Check canonical tags, which identify each page’s preferred URL, and verify consistent pagination links so search crawlers can reach later pages, including content behind infinite scroll.
Measure page loading speed and identify what prevents a page from loading in under three seconds. Use performance measurements to guide improvements such as lazy loading, caching, CDN delivery, and reducing resource costs.
Review pagination markup so people using screen readers or keyboards can understand their current page and move between pages. Check navigation labels, current-page attributes, focusable controls, and announcements when the page changes.
Set and review limits for bundled file size and page performance so CI, automated checks on code changes, can catch regressions. Check enforcement on pull requests and review production monitoring for slowdowns after release.
Review messages that display counts and check whether each target language gets the correct plural form. Replace simple number-and-text joins or singular/plural branches with Intl.PluralRules or ICU MessageFormat, which select wording according to language-specific rules.
Review HTML object elements and add meaningful fallback content for people who cannot load or view embedded material. Identify missing alternatives, suggest text or appropriate HTML elements, and explain how to verify accessibility.
Audit website redirects after URL migrations, domain changes, or CMS upgrades. Record each redirect path and HTTP status code, identify unnecessary steps or loops, and update redirects to point directly to the final destination.
Review stylesheets for a CSS reset or normalization layer that reduces differences in browser defaults. Check import order, framework provisions, and rendered layouts across screen sizes and interaction states, then suggest changes for a consistent styling foundation.
Audit page loading and choose resource hints, browser instructions for fetching files or preparing connections early. Use measurements to identify delays, then suggest preload, preconnect, prefetch, or dns-prefetch for critical assets, external services, and likely next-page resources.
Create a custom offline page and configure a service worker, a browser background script, to cache it in advance. Show it when page navigation fails, and review resource dependencies and fallback conditions.
Audit and add structured organization data on a business or brand homepage. Check machine-readable details such as the official name, logo, contact information, and social profiles to help Google understand the organization and its search information panel.
Check images used in social link previews through Open Graph metadata. Verify dimensions, aspect ratio, file size, and HTTPS URLs, then resize assets and update tags to reduce missing images and unwanted cropping.
Audit a page’s social sharing URL against its canonical URL, the preferred page address. Identify differences in domains, paths, or tracking parameters, and align the tags to address split share counts.
Measure the total size of a web page and its resources, identify what slows loading, and reduce unnecessary weight. Use a 1500KB limit to guide image optimization, code compression, and removal of unused resources.
Review slow page loads and choose resource hints, browser instructions that start loading or connecting earlier. Use measurements to identify bottlenecks, then recommend preload, preconnect, prefetch, or dns-prefetch for important assets and likely next-page resources.
Review URL parameters used for filters, sorting, pagination, and tracking. Check canonical tags, which identify a preferred page URL, and recommend consistent handling of URL variants to address duplicate content and unnecessary search engine crawling.
Review form fields for code that blocks pasting, then remove those restrictions. The skill helps check password manager use, keyboard interactions, and accessibility so people can paste passwords and other long values into inputs.
Review HTTP response headers and restrict browser features an application does not need, such as camera, microphone, and location access. Guide Permissions-Policy settings that limit what attackers could use if the site is compromised.
Review whether every page provides an accessible privacy policy link, especially in the footer. Check that the policy explains data collection, use, sharing, retention periods, contact details, and user rights, and identify missing information.
Review early connections to third-party services such as fonts and APIs. Use loading measurements to identify essential domains, recommend preconnect hints that prepare connections in advance, and remove unnecessary hints that add overhead.
Review website text and interface instructions for jargon, complex sentences, and unclear actions. Simplify wording, explain technical terms, and adjust reading difficulty so the intended audience can understand content and follow instructions.
Find important pages that receive no links from elsewhere on the site. Compare crawl results with sitemaps and indexed pages, then suggest relevant existing pages where descriptive internal links could help connect the content.
Review images displayed at different screen sizes and help browsers select appropriately sized files. Check srcset image options, sizes display-width hints, and CSS layout together to identify oversized mobile downloads or mismatched image variants.
