# SEO Chrome Extension with Instant Grades A free SEO Chrome extension that grades any page A–F: a full on-page SEO analysis in one click. Title length, meta tags, heading structure, alt text, schema markup and Core Web Vitals, right in your browser. Free forever, no account required. Install it from the Chrome Web Store: https://chromewebstore.google.com/detail/seo-bandwagon/dphmaddiedhkejfhabkfdenfphjljioj ## What it checks 8 data categories, one click: - **Title & meta**: title tag character count, meta description length, robots and canonical tags, missing tags flagged. - **Heading structure**: H1–H6 outline view, multiple H1 warnings, skipped heading levels, keywords in headings. - **Images & media**: missing alt text, image count and audit, lazy loading check, alt text coverage. - **Performance**: Core Web Vitals measured live (LCP, CLS, INP), page load time, tech stack. - **Links**: internal and external link counts, nofollow detection, anchor text analysis. - **Structured data**: JSON-LD detection, schema type identification, parse error flags, per-type breakdown. - **Social & OG**: Open Graph tags, Twitter Card tags, social preview check, missing OG images. - **Content & readability**: word count, Flesch-Kincaid readability, keyword density, top words and phrases. ## Under the hood - **Title & meta checker**: character counts for titles (50–60 recommended) and meta descriptions (150–160), color-coded, with a live preview of the Google result. - **Heading structure analyzer**: every heading as an indented outline, with multiple H1s, skipped levels and empty headings flagged. - **Structured data viewer**: every JSON-LD block on the page, the schema types present, and anything that fails to parse. - **Core Web Vitals in your browser**: LCP, CLS, INP, FCP and TTFB measured live as the page loads, with no separate speed test to run. - **A grade, and the fix list**: every check feeds a 0–100 score with a letter grade and four sub-scores (Meta, Content, Links, Tech), and each point deducted comes with the change that earns it back. ## How it compares Inspection extensions show a page's raw SEO data fast. SEO Bandwagon also evaluates what it finds, so you leave with a grade and a fix list. Each comparison is dated and checked against the other extension's own Chrome Web Store listing: - SEO Bandwagon vs Detailed SEO Extension: https://seobandwagon.com/seo-chrome-extension/vs/detailed-seo-extension - SEO Bandwagon vs Ahrefs SEO Toolbar: https://seobandwagon.com/seo-chrome-extension/vs/ahrefs-seo-toolbar - SEO Bandwagon vs Keyword Surfer: https://seobandwagon.com/seo-chrome-extension/vs/keyword-surfer - SEO Bandwagon vs SEO Minion: https://seobandwagon.com/seo-chrome-extension/vs/seo-minion ## Which SEO analyzer is best for beginners? One that explains what it finds. A beginner needs to know what to fix first, not a list of tags to decode. That is what this extension is built for: it grades a page from A to F and ties every point it takes off to the change that earns it back, next to the same raw data the inspection extensions show. It is free and needs no account. ## Does Google have a free SEO tool? Yes. Search Console is Google's free tool for seeing how your site performs in Google Search, and PageSpeed Insights measures how fast a page loads. Neither grades the on-page SEO of the page in front of you, which is what the extension does. They work well together: Search Console for how Google sees the whole site, the extension for what to fix on each page. ## What is the difference between the extension and the free SEO audit? The extension checks the page you are looking at, in your browser, with no account. The audit scans your site from our servers and needs a free sign-in. The audit runs 10 automated checks, among them backlinks and page speed measured from outside your browser, and the free plan allows 10 scans a day. Use the extension on each page as you edit it, and the audit to see where the site stands. ## More questions ### Is the extension really free? Yes: free forever, with no trial period, no feature gates, and no upsell required to see your results. If you want more than single-page checks, the site audit is free too, with a free account. ### Do I need an account? No. Every analysis runs without signing in, and your capture history is stored locally in your browser. Connecting a SEO Bandwagon dashboard account is optional: it syncs captures for reporting. ### How do I check a page's SEO in Chrome? Install the extension, open any web page, and click the extension icon (or press Cmd+Shift+S on Mac, Ctrl+Shift+S on Windows). You get an overall grade plus sections for meta tags, headings, images, links, structured data, content and performance. ### Does it work on any website? It analyzes any page you can open in Chrome, including JavaScript-rendered content, because it reads the rendered page in your browser. Like all extensions, it cannot run on Chrome's internal pages or the Chrome Web Store. ### How is the SEO score calculated? On-page checks (title and meta description length, heading hierarchy, image alt text, link attributes, structured data, content depth and readability) are weighted by impact into a 0–100 score, mapped to a letter grade from A to F.
