Review blog posts, product descriptions, and landing pages for SEO content quality. Check whether they answer readers' search needs, support claims with evidence, show relevant authorship, and offer specific details, then identify areas to rewrite or expand.
Audit XML sitemaps for URLs marked noindex, an instruction to exclude pages from search results, and for unsuccessful responses. Identify conflicting entries and recommend removing either the sitemap entry or the noindex instruction according to the page’s intended visibility.
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 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 website animations against users’ reduced motion preferences, a setting that requests less movement. Check flashing content, scrolling effects, alternative transitions, pause controls, and advance warnings, and identify changes needed in rendered pages and interactive states.
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.
Review parallax effects, where backgrounds and foregrounds move at different speeds. Check reduced-motion support and access to essential content, then suggest static alternatives and an optional site-wide control for disabling motion.
Audit business addresses on contact pages and footers for completeness and clear HTML markup. Compare visible details with structured data, which describes the business to search engines, and Google Business Profile to identify inconsistencies.
Find CSS and JavaScript that delay a page’s first visible content. Confirm the bottleneck with browser tools or performance data, then adjust loading behavior and inline essential styles to help the page start rendering sooner.
Add or review Product structured data, machine-readable product details, on shop pages. Check names, images, prices, availability, and ratings against visible content, then validate the markup for eligibility to show enhanced Google search results.
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.
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.
Review Referrer-Policy settings to limit sensitive URL details shared when visitors follow external links. Check response headers and pages containing private parameters, suggest suitable policy values, and explain how to verify the resulting browser behavior.
Audit account settings, privacy pages, and API routes for a complete data deletion flow. Check browser storage cleanup, server deletion requests, and user confirmation, then identify missing pieces and guide implementation.
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.
Check and add structured data that describes user reviews and average ratings on product or service pages. Verify required fields against real reviews and validate the markup for star-rating search results.
Review fixed pixel values in fonts, widths, and spacing, then suggest relative units that adapt to available space and browser font preferences. Check rendered layouts at different screen widths and during interactions before proposing changes.
Audit internal links after URL migrations, domain changes, or site rebuilds. Trace redirects, record source pages and final destinations, and guide link updates so visitors and search crawlers reach the destination without extra redirect requests.
Review blog posts, landing pages, and guides for readability. Estimate reading difficulty, identify long sentences and jargon, and simplify wording and paragraph structure so broad audiences can follow the content more easily.
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 picture elements that select images by format or display conditions. Check fallback images, alternative text, dimensions, and source ordering, then provide corrected HTML with JPEG or PNG fallbacks for browsers that cannot use the selected formats.
Audit important pages for settings that hide descriptions in Google search results. Check robots meta tags and response headers, report affected URLs, and adjust snippet controls after confirming whether the restriction is intentional.
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.
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.
