For SEO Specialists
SEO Audit Workflow Without External Tools
onHover gives SEO specialists and content teams four tools that cover on-page signals, Core Web Vitals, competitor tech analysis, and page data export — all from one Chrome extension popup, on any page, including authenticated and staging URLs that external tools cannot reach.
4 tools for SEO audit work
SEO Analyzer
Complete on-page audit without opening a new tab
onHover's SEO Analyzer surfaces every SEO signal on the current page in one panel: title tag and its length, meta description, canonical URL, robots directives (index/follow/noindex), Open Graph tags, Twitter Card tags, heading hierarchy (H1 through H6), internal and external links, and structured data (JSON-LD and microdata). Click once and everything is there — no page source, no third-party crawl, no waiting.
Signals covered
Page Insights
Core Web Vitals directly relevant to rankings
Google uses LCP, CLS, and INP as ranking signals via the Page Experience update. onHover's Page Insights captures all five Core Web Vitals — LCP (Largest Contentful Paint), FCP (First Contentful Paint), CLS (Cumulative Layout Shift), INP (Interaction to Next Paint), and TTFB (Time to First Byte) — as a live snapshot from the browser's Performance API. No tab submission, no 30-second wait, no authentication walls. Works on localhost, staging, and any URL behind a login.
Signals covered
Tech Stack Detector
Understand competitors' CMS, analytics, and CDN setup
Knowing a competitor's tech stack informs SEO strategy: their CMS affects crawlability and rendering mode (server-side vs. client-side), their CDN affects TTFB globally, and their analytics tools reveal how they measure performance. onHover's Tech Stack Detector identifies CMS (WordPress, Shopify, Webflow, etc.), frontend framework (React, Next.js, Nuxt, etc.), analytics tools (Google Analytics, Hotjar, Segment, etc.), CDN provider, hosting environment, SSL certificate details, and DNS records — all from the current browser tab.
Signals covered
Extract & Export
Pull page data for analysis or LLM context
onHover's Extract & Export tool converts the current page into structured data you can work with. Export the full page as Markdown (clean text, no HTML tags) for analysis in a spreadsheet or as context for an LLM prompt. Extract all email addresses grouped by domain, export tables as CSV, or save the full HTML, PDF, or Word document. Useful for content audits, competitive analysis, or feeding page content into AI-assisted SEO workflows.
Signals covered
The SEO audit workflow
A repeatable process for a complete on-page audit on any URL — including pages behind authentication, staging environments, and localhost.
Open the target page
Navigate to the page you're auditing in Chrome.
SEO Analyzer
Check title, description, canonical, robots, OG tags, headings, and structured data in one panel.
Page Insights
Capture Core Web Vitals — LCP, CLS, INP, FCP, TTFB — and note which signals are outside the "Good" threshold.
Tech Stack Detector
Identify the CMS, rendering mode, analytics setup, and CDN — relevant context for diagnosing crawl or performance issues.
Extract & Export
Export the page as Markdown for content analysis or as input to an LLM-assisted audit prompt.
Repeat on competitor pages
Run the same workflow on competitor URLs for a side-by-side comparison without additional tooling.
Works where external tools cannot
Tools like PageSpeed Insights and SEOquake send your URL to an external server for analysis. That means they cannot audit pages that require authentication (dashboards, gated content, preview links), pages on localhost or staging servers, or pages behind a VPN.
Because onHover runs directly in your browser tab, it audits any page you can open — including authenticated pages, staging environments, and localhost — with the same full access as the browser itself.
Common questions
Can onHover audit pages behind authentication, staging URLs, or localhost?
Yes — this is one of onHover's main advantages over external SEO tools. Since it runs directly inside your browser tab, it has the same page access you do. Any URL you can open in Chrome can be audited: authenticated dashboards, preview links, staging environments, and localhost.
How is onHover's Page Insights different from Google's PageSpeed Insights?
PageSpeed Insights sends your URL to Google's servers for a simulated, throttled crawl — it cannot test pages behind logins, staging URLs, or localhost. onHover's Page Insights reads live data from the browser's Performance API during the actual page load, measuring real user experience under current conditions. Results appear instantly instead of waiting 20–30 seconds for a remote report.
Does the SEO Analyzer check structured data?
Yes. The SEO Analyzer parses all JSON-LD blocks and microdata on the current page and displays them in a readable format. You can see the schema types present, their properties, and verify that the structured data matches what you intended to mark up.
Which meta tags does the SEO Analyzer surface?
The SEO Analyzer shows: title tag and character length, meta description and character length, canonical URL, robots directives (index/noindex, follow/nofollow), Open Graph tags (og:title, og:description, og:image, og:type, og:url), Twitter Card tags, all heading levels H1–H6, internal and external link counts, and all JSON-LD and microdata blocks on the page.
Can I export audit data for reports or client deliverables?
Use the Extract & Export tool to export the current page as Markdown — clean text with structure preserved, ready for pasting into a report or feeding into an LLM prompt. You can also export tables as CSV and save the full page as HTML or PDF.
