FREE SEO CHROME EXTENSION · 8 DATA CATEGORIES · ONE CLICK
A full on-page SEO analysis in one click. Title length, meta tags, heading structure, alt text, schema markup, Core Web Vitals — everything, right in your browser.
8 data categories, one click. Everything you'd open five tabs and DevTools to find — on the page, in context.
Titles should be 50–60 characters, meta descriptions 150–160. The extension shows the counts with color-coded warnings — green optimal, yellow borderline, red too short or too long — plus a live preview of how your title and description look in a Google result.2
Extracts every heading on the page, shows it as an indented outline, and flags the problems: multiple H1s, skipped levels (H1 → H3 with no H2), empty headings. It also surfaces the keywords your headings actually use, so you can check that your target term appears in the H1 and supporting H2s.
Parses every JSON-LD block on the page and shows the schema types present — Article, Product, LocalBusiness, FAQPage — plus anything that fails to parse. See schema in context, on your pages and your competitors’, while you are reviewing or editing content.
LCP, CLS, INP, FCP and TTFB are measured live in your browser as the page loads — real numbers from the page you are actually on, with no separate speed test to run and no DevTools to open. If a competitor passes and you don’t, that is a gap you can close.
Every check feeds a 0–100 score with a letter grade and four sub-scores — Meta, Content, Links, Tech. Each point deducted comes with the change that earns it back, so a B− stops being a mystery and becomes a short list: a title 12 characters too long, one missing H2, four images without alt text.
Detailed SEO Extension, SEO META in 1 CLICK, and SEOquake are excellent inspection tools with huge install bases — they show you a page's raw SEO data fast. The difference is what happens next: SEO Bandwagon also evaluates what it finds, so you leave with a grade and a fix list instead of a wall of data.

Rows describe each extension as published on August 26, 2026, each checked against its own Chrome Web Store listing345. “Not stated” means exactly that: the capability is absent from that publisher’s own listing and documentation, and we will not turn silence into a claim that their product lacks it. Detailed SEO Extension is published by Ahrefs and reports 600,000 users at 4.9★; we are new and have neither. What we are comparing is what each tool does, not how many people use it.
It depends on what you want from it. Inspection tools like Detailed SEO Extension and SEO META in 1 CLICK show you raw page data — titles, headings, meta tags — and assume you know what to do with them. SEO Bandwagon is built for people who want a verdict: it scores the page 0–100, assigns a letter grade, and lists the specific fixes that would raise it, alongside the same raw data the inspection tools show.
Install the SEO Bandwagon extension from the Chrome Web Store, open any web page, and click the extension icon (or press Cmd+Shift+S on Mac, Ctrl+Shift+S on Windows). You'll see an overall grade plus collapsible sections for meta tags, headings, images, links, structured data, content, and performance.
Yes — free forever, with no trial period, no feature gates, and no upsell required to see your results. It's built by SEO Bandwagon, and if you want more than single-page checks, our full site audit is where the paid platform starts.
No. Every analysis runs without signing in, and your capture history is stored locally in your browser. Connecting to a SEO Bandwagon dashboard account is optional — it lets you sync captures for reporting, but the extension is fully functional offline without it.
It analyzes any page you can open in Chrome — your site, a competitor's site, a staging environment, a client prospect. Analysis runs against the rendered page in your browser, so it sees what you see, including JavaScript-rendered content. (Like all extensions, it can't run on Chrome's internal pages or the Chrome Web Store itself.)
The extension runs a battery of on-page checks — title and meta description length, heading hierarchy, image alt text, link attributes, structured data, content depth and readability — and weights each issue by impact to produce a 0–100 score, mapped to a letter grade from A to F. Every point deducted comes with the recommendation that would earn it back.
Free forever. No account required. Check your pages — and your competitors'.
Best-practice length ranges are widely cited industry guidelines, not fixed rules — Google renders titles and descriptions by pixel width, so treat them as targets. Product facts describe the extension as shipped. Competitor rows describe each extension as published on the date above; they change their products, so we re-check before every publish rather than leaving a stale claim standing.
