Crawlsite by DidYouSEO

Comprehensive SEO and technical audit for any webpage

Crawlsite by DidYouSEO — Comprehensive SEO & Technical Audit for Any Webpage Crawlsite turns any browser tab into an instant, on-page SEO and technical audit. One click opens a side panel that analyzes the page you're viewing — titles, meta tags, heading structure, links, images, structured data, social tags, and core technical signals — and surfaces exactly what's helping or hurting that page in search. No account, no crawling delay, no copy-pasting URLs into a dashboard. Just open the panel and read the results. Built for SEO specialists, content writers, developers, agencies, and site owners who want to check a page the moment they're looking at it, Crawlsite does the tedious inspection work for you and organizes findings into clear, actionable categories. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ WHY CRAWLSITE ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Most SEO tools make you leave the page, enter a URL, wait for a crawler, and then dig through a report. Crawlsite runs where you already are. It reads the live, rendered DOM of the current tab — so you see what search engines and users actually get, including content injected by JavaScript. Results appear in seconds, right beside the page. • Instant — audits the page you're on, no URL entry, no waiting on a queue • Accurate — analyzes the fully rendered page, not just raw HTML • Organized — findings grouped into Overview, Headings, Links, Images, Schema, Social, and Advanced • Private — analysis happens locally in your browser • Exportable — download the full audit as a CSV for reporting or tracking • Customizable — set your own thresholds for titles, descriptions, and more • Lightweight — vanilla JavaScript, no bloat, no external dependencies ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ WHAT IT CHECKS ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ OVERVIEW — Your at-a-glance health dashboard Open the panel and immediately see a prioritized summary of what needs attention. Issues are sorted into Critical, Warning, and Info so you know what to fix first. Instead of reading every tab, start here to understand the overall SEO health of the page and jump straight to the problems that matter. HEADINGS — Structure and hierarchy analysis Headings tell search engines how your content is organized. Crawlsite maps the full H1–H6 hierarchy of the page and flags common structural problems: • Missing H1 tag • Multiple H1 tags competing for relevance • Skipped heading levels that break logical hierarchy • Empty headings See the complete outline of the page at a glance and confirm your content follows a clean, semantic structure that both users and crawlers can follow. LINKS — Internal and external link auditing Links drive crawlability, authority flow, and user navigation. Crawlsite inspects every anchor on the page and reports: • Total internal vs. external link counts • Empty anchors and links with no descriptive text • Link distribution across the page Quickly spot navigation gaps, thin anchor text, and linking patterns that could be strengthened for better internal linking and crawl efficiency. IMAGES — Accessibility and optimization checks Images affect accessibility, page performance, and image search visibility. Crawlsite reviews every image on the page for: • Missing alt text (an accessibility and SEO problem) • Image sizing and dimension issues Get an immediate list of images that need attention so you can improve accessibility, meet compliance expectations, and give search engines the context they need to index your visuals. SCHEMA — Structured data validation Structured data powers rich results, knowledge panels, and increasingly, AI-driven answers. Crawlsite detects schema.org structured data on the page and validates the markup so you can confirm your JSON-LD, microdata, or RDFa is present and correctly formed. Catch missing or malformed structured data before it costs you a rich result. SOCIAL — Open Graph and social meta tags When your page is shared, social platforms read Open Graph and Twitter Card tags to build the preview. Crawlsite verifies these social meta tags so your links look right everywhere they're shared: • Open Graph (og:title, og:description, og:image, and more) • Twitter Card tags Avoid broken or blank share previews that quietly reduce click-through on social and messaging platforms. ADVANCED — Core technical SEO signals The technical foundation that determines whether a page can rank at all. Crawlsite surfaces the essential signals in one place: • HTTPS / secure connection status • Canonical tag presence and value • Robots meta directives (index/noindex, follow/nofollow) • Viewport meta tag for mobile readiness • Additional technical metadata Confirm the page is indexable, canonicalized correctly, mobile-ready, and served securely — the checks that are easy to overlook and expensive to get wrong. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ TITLE & META DESCRIPTION VALIDATION ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Crawlsite checks the two elements that most directly shape your search snippet: • Page title — presence and length validation against best-practice limits • Meta description — presence and length validation Titles and descriptions that are too long get truncated in results; too short and you waste valuable snippet space. Crawlsite tells you exactly where each stands so you can write snippets that earn clicks. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ CUSTOMIZABLE THRESHOLDS ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Every site and team has its own standards. In Settings, you can tune the audit thresholds Crawlsite uses — such as title and description length limits — so the warnings match your guidelines instead of a one-size-fits-all rule. Your preferences are saved locally and applied to every page you audit. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ CSV EXPORT ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Turn any audit into a shareable deliverable. Export the complete results as a CSV with one click — ready to drop into a spreadsheet, attach to a client report, hand off to a developer, or track improvements over time. Perfect for agencies and consultants who need to document findings and demonstrate progress. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ HOW TO USE ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Visit any webpage you want to audit. Click the Crawlsite icon to open the side panel. Crawlsite automatically analyzes the current page. Start on the Overview tab for a prioritized health summary. Switch between Headings, Links, Images, Schema, Social, and Advanced for detailed findings. Adjust thresholds in Settings to match your standards. Export the results as CSV whenever you need to report or track. The side panel stays open as you browse, so you can move from page to page and re-audit instantly — ideal for reviewing a whole site section, QAing a new template, or spot-checking pages before and after a change. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ WHO IT'S FOR ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ • SEO specialists — audit any page in seconds without leaving the tab • Content writers & editors — check titles, descriptions, and heading structure before publishing • Web developers — verify canonical tags, robots directives, structured data, and technical hygiene during builds and QA • Agencies & consultants — produce quick, exportable audits and client-ready CSV reports • Site owners & marketers — understand what's helping or hurting a page without needing to be an SEO expert • Anyone auditing competitors — inspect any public page's on-page SEO the same way you'd inspect your own ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ BUILT FOR SPEED AND PRIVACY ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Crawlsite is built on Chrome's Manifest V3 with vanilla JavaScript and no third-party dependencies. The analysis runs locally in your browser against the page you're viewing — it reads the current tab to perform the audit and stores your settings locally. It's fast, focused, and stays out of your way until you need it. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ KEY FEATURES AT A GLANCE ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ✓ One-click, instant on-page SEO audit in a convenient side panel ✓ Overview dashboard with Critical / Warning / Info prioritization ✓ Full H1–H6 heading structure analysis ✓ Internal & external link audit with empty-anchor detection ✓ Image alt-text and sizing checks ✓ schema.org structured data detection and validation ✓ Open Graph & Twitter Card social tag verification ✓ Technical checks: HTTPS, canonical, robots, viewport, and more ✓ Title & meta description length validation ✓ Customizable audit thresholds ✓ One-click CSV export ✓ Analyzes the live, JavaScript-rendered page ✓ Manifest V3, lightweight, no external dependencies ✓ Local analysis — no account required ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Stop switching between the page and a separate dashboard.
