How to Audit the SEO of Any Page in 10 Seconds

You just published a page. Or maybe you're looking at a competitor's site. Either way, you want to know: is the SEO actually set up right?

Most people would open a paid tool, paste in the URL, wait for it to crawl, sign up for an account, and eventually get a report they don't fully understand. That's a lot of friction for what should be a simple question.

What if you could just click a button and get the answer in 10 seconds — right from your browser?

That's exactly what our free Chrome SEO Audit Extension does. No account, no tracking, no data ever leaving your browser. Just instant answers.

Here's how to use it — and what to look for.

Step 1: Install the Extension

Head to the Chrome Web Store and click "Add to Chrome." It's under 100KB — smaller than most images on your page. It won't slow your browser down.

No sign-up. No email. No credit card. Just install and go.

Step 2: Navigate to Any Page

Go to any website — your own, a client's, a competitor's. The extension works on every page you can visit in Chrome.

Step 3: Click the Extension Icon

Click the extension icon in your toolbar and you'll instantly see a full breakdown of the page's SEO health. Everything runs client-side — nothing is sent to any server, ever.

Here's what it checks:

The 10 Things It Checks

1. Page Title

Does the page have a title tag? Is it too long and likely to get truncated in search results? Google typically displays the first 50–60 characters. If your title is 90 characters, searchers are seeing a cut-off mess. The extension flags this immediately.

2. Meta Description

Your meta description is your pitch in search results. Missing one? Google will auto-generate something — and it's usually terrible. The extension checks whether one exists and shows the character count so you can keep it in the 150–160 sweet spot.

3. Headings (H1–H4)

Every page should have exactly one H1. Multiple H1s confuse search engines about what the page is actually about. No H1 at all? Even worse. The extension counts all heading levels and flags issues.

4. Images

Images without alt text are invisible to search engines and inaccessible to screen readers. The extension checks every image for alt text, width/height attributes, lazy loading, and fetch priority. Missing alt text on your hero image? You'll know instantly.

5. Open Graph Tags

When someone shares your page on Facebook, LinkedIn, or Slack, Open Graph tags control what shows up — the title, description, and image. Missing og:image? Your shared links will look broken and unprofessional. The extension validates all five key OG tags.

6. Twitter Card Tags

Same idea as Open Graph, but for X (Twitter). The extension checks for twitter:card, twitter:title, twitter:description, and twitter:image.

7. Links

How many links are on the page? How many are internal vs. external? A page with 200 external links and 2 internal links is leaking authority. The extension gives you the breakdown at a glance.

8. Structured Data

JSON-LD structured data helps Google understand what your page is — a product, a service, a blog post, a local business. The extension detects JSON-LD blocks and reports which Schema.org types are present. No structured data? That's a missed opportunity for rich results.

9. Core Web Vitals Hints

The extension can't run a full Lighthouse audit (that requires a separate environment), but it can flag common issues that affect Core Web Vitals: potential CLS triggers, LCP candidates, missing lazy loading, and render-blocking resources. Think of it as a quick sniff test.

10. Technical SEO Foundations

The boring-but-critical stuff: canonical URL, viewport meta tag, HTML lang attribute, and robots directives. Missing a canonical? You might have duplicate content issues. No viewport tag? Your mobile experience is broken. The extension catches all of it.

Why This Matters

Most SEO problems aren't complicated — they're just invisible. A missing meta description, an image without alt text, a broken OG tag. These are 30-second fixes that silently cost you traffic and clicks every day.

The problem isn't fixing them. It's noticing them. That's what this tool is for.

Use it on every page you publish. Use it on your competitors. Use it on client sites during discovery calls. It takes 10 seconds and it's free.

How We Use It at Weddle Media

We built this tool because we needed it. Before every site launch, we run the extension on every page to catch anything we missed. It's become part of our pre-launch checklist:

• Does every page have a unique title and meta description?
• Are all images alt-tagged?
• Is Open Graph set up so shared links look good?
• Is structured data present on key pages?
• Are there any CLS triggers or missing lazy loading?
• Is the canonical URL correct?

If you're a web designer, developer, or SEO — this saves you from embarrassing oversights. If you're a business owner, it helps you verify that whoever built your site actually did the SEO work they promised.

A Note on Privacy

Everything runs inside your browser. We don't collect your browsing history, page content, or personal information. No cookies, no tracking pixels, no analytics. The audit results exist only in memory while the popup is open — close it, and the data is gone.

You can read the full privacy policy if you're curious, but the short version is: we don't want your data. We just want to help you fix your SEO.
