See the page search engines have to interpret.
Metadata, headings, copy, links, images, structured data, social tags, international signals, and accessibility are read from the live DOM.
Automatic reruns follow reloads and same-tab navigation.
SEO audit extension for Chromium and Firefox
The SEO audit stays local.
Inspect rendered pages, technical signals, internal links, accessibility, and Search Console data without handing your work to another platform.
No account needed for page audits. Search Console is optional.
Rendered page evidence
Checks the DOM people and search engines receive after scripts run.
Actionable findings
Every issue carries evidence, context, and a practical next step.
DevTools inspection
Open relevant code in Elements instead of hunting through the page.
Private by design
No Rank On Top backend, telemetry, ad profile, or click tracking.
One page, more context
Most audit tools start with a URL upload. This one starts with the page already open.
Rank On Top combines what is rendered, what the network says, and how the page fits into the site.
Check the response around the page.
Review redirects, headers, robots rules, sitemaps, link responses, charset, and indexability conflicts with explicit permission.
Trace how pages connect.
Crawl a site locally to expose depth, internal paths, redirects, noindex pages, duplicate titles, link graphs, and page trees.
A practical workflow
Scan quickly. Investigate deeply.
The side panel keeps the decision clear. DevTools keeps the evidence close.
-
Open the page you care about
Rank On Top audits the active tab, performs a bounded full-page scroll to load lazy content, and refreshes when the page changes.
-
Use the side panel for the decision
Read overall and category scores, lab signals, top blockers, and the next useful action without losing the page.
-
Open DevTools for the evidence
Work through grouped findings, previews, code evidence, mobile comparisons, image diagnostics, and site visualizations in a larger space.
-
Connect real search demand when useful
Optional read-only Search Console access adds queries, pages, clicks, impressions, sitemaps, and URL inspection to the audit context.
What it checks
Broad enough for an audit. Specific enough to fix.
Scores summarize the work. Evidence and suggestions explain what actually changes the result.
- Search appearance
- Titles, descriptions, canonicals, robots directives, Google previews, rich-result eligibility, Open Graph, and social previews for major platforms.
- Content structure
- Heading order, main-content signals, language, phrase discovery, user-supplied keyword coverage, descriptive density, and practical content gaps.
- Images and accessibility
- Alternative text, labels, ARIA references, landmarks, focus order, targets, frames, autoplay, rendered versus intrinsic image size, bytes, and local WebP export.
- Links and architecture
- Internal and external links, anchors, status checks, crawl depth, page trees, inbound and outbound counts, redirect chains, robots rules, and sitemaps.
- Modern discovery
- Structured data, international alternates, AI crawler rules, optional llms.txt analysis, citation readiness, and current Google Search Gallery support.
- Page experience
- Observed Web Vitals, local lab diagnostics, desktop and mobile render comparison, lazy content, response headers, compression signals, and network timing evidence.
Optional Google access
Search Console context, read only and direct.
Connect only when you want first-party search performance beside the page audit.

Privacy is product architecture
Your audit is not our dataset.
Rank On Top has no account system, analytics SDK, advertising profile, or vendor backend. Page analysis runs in the browser.
Read the privacy policyCommon questions
Before you install.
Does Rank On Top upload the page I audit?
No. Rendered DOM analysis and scoring happen inside the extension. Network tools contact only the origin you explicitly choose, and do so without account cookies. Nothing is uploaded to Rank On Top.
Does it replace Lighthouse or Search Console?
No. It brings page evidence, local lab signals, SEO checks, accessibility, site structure, and optional Search Console context into one browser workflow. Native Lighthouse and Search Console remain useful sources.
Why does the extension request page access?
It needs access to the active tab to inspect its rendered DOM. Broader site access is requested only when you start an origin-scoped network audit or crawl.
Which browsers are supported?
Rank On Top builds for Manifest V3 Chromium browsers and Firefox. Some browser UI, such as the side panel, follows the capabilities and conventions of each browser.
