THE SEO CHROME EXTENSION THAT GRADES EVERY PAGE

SEE YOUR SEO SCORE IN ONE CLICK

Most SEO checker extensions stop at showing you the data. This one reads it for you. Here's how to check any page's SEO in Chrome:

  1. 1

    Install the extension

    One click from the Chrome Web Store. No sign-up, no configuration.

  2. 2

    Open any page and click the icon

    Or press Cmd+Shift+S (Mac) / Ctrl+Shift+S (Windows). The analysis runs instantly on the page you're viewing.

  3. 3

    Read the grade — and the fix list

    A 0–100 score with a letter grade, and a prioritized list of recommendations. Every deduction shows the change that earns the points back.

A page that grades a B− isn't a mystery anymore — it's a short list: a title tag 12 characters too long, one missing H2, four images without alt text. Fix them, re-run, watch the grade move.

EVERYTHING THE EXTENSION CHECKS

Every check feeds the score. One click runs them all.

TITLE TAG & META DESCRIPTION CHECKER

Title tags should be 50–60 characters. Meta descriptions 150–160 characters. Too short and you're wasting valuable real estate. Too long and Google truncates them in the SERP — sometimes replacing them entirely.

The extension shows character counts with clear warnings, and a live SERP preview of how your title and description will actually look in Google search results — before you publish, not after.

Word count and character count are built in — useful for editors checking content length, writers hitting target word counts, and developers validating dynamic title tag templates.

HEADING STRUCTURE ANALYZER

Proper heading hierarchy (H1 → H2 → H3) helps Google understand your content structure and helps users navigate your page. A broken heading structure is one of the most common and easiest-to-fix SEO issues.

The extension extracts every heading tag on the page, shows it as an indented outline, and flags problems: multiple H1s, skipped heading levels (H1 → H3 with no H2), and headings with no text.

It also surfaces the keywords your headings actually use — a fast check on whether your target term appears in the H1 and supporting H2s.

STRUCTURED DATA VIEWER

The extension parses every JSON-LD block on the page and shows you the schema types present — Article, Product, LocalBusiness, FAQPage — plus anything that fails to parse.

No more copy-pasting into a separate testing tool just to see what markup a page carries. See schema in context, on your pages and your competitors', while you're reviewing or editing content.

CORE WEB VITALS IN YOUR BROWSER

LCP, CLS, and INP are measured live in your browser as the page loads — real numbers from the page you're actually on, with no separate PageSpeed test to run and no DevTools to open.

Check your pages AND your competitors' pages. Core Web Vitals is a ranking signal — if your competitor is passing and you're not, that's a gap you can close.

HOW IT COMPARES TO OTHER SEO CHROME EXTENSIONS

Detailed SEO Extension, SEO META in 1 CLICK, and SEOquake are excellent inspection tools with huge install bases — they show you the 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.

BUILT FOR REAL WORKFLOWS

Agencies & Freelancers

Pre-audit a prospect during the sales call. Open their homepage, hit the shortcut, and you're quoting from their actual grade — 'you're at a C+, here are the three things costing you' — before the competition has finished their pitch deck.

Content Teams

Check every draft before it ships. Title length, heading structure, readability, and the SERP preview in one pass — so the page publishes at an A instead of getting patched after it's already indexed.

Developers

Verify a deploy didn't break SEO. Canonical tags, robots directives, structured data, and live Core Web Vitals on staging or production, plus a JSON export of the full analysis for your records.

PRIVATE BY DESIGN

Analysis runs locally in your browser and your capture history is stored on your machine — the extension works fully offline, with no account and no sign-in. Syncing captures to a SEO Bandwagon dashboard is optional and off by default.

FREQUENTLY ASKED QUESTIONS

What is the best SEO extension for Chrome?

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.

How do I check a page's SEO in Chrome?

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.

Is the extension really free?

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.

Do I need an account?

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.

Does it work on any website?

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.)

How is the SEO score calculated?

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.

GRADE YOUR FIRST PAGE IN 30 SECONDS

Install the extension, open any page, and see what's helping — and hurting — its rankings. And when one page isn't enough, run a free site-wide audit on the SEO Bandwagon platform.
