7 Free Chrome Extensions We Built for SEO, Site Health, and Conversion Audits

We do a lot of SEO and website audits. Over the past few months we kept hitting the same wall: the existing free tools either nag you to upgrade, harvest your data, or simply don’t show what we needed. So we built our own — and shipped them to the Chrome Web Store, free, with no signup wall.

Here are seven of them. All published, all free, all do one job well.

1. SEO Snapshot

A one-click on-page SEO audit. Run it on any page and you get title length, meta description length, H1/H2 hierarchy, image alt-text coverage, schema presence, internal/external link counts, and a quick checklist of the wins you can ship in the next ten minutes.

We built this because the tools that do this either pop a paywall after the second page or take 90 seconds to load. SEO Snapshot is instant.

2. Website Health Auditor

Goes deeper than SEO Snapshot — adds Core Web Vitals (LCP, INP, CLS), accessibility flags, broken-link sweep, and HTTPS/security header coverage. Run it on a client’s site at the start of an engagement and you have a one-page brief in 30 seconds.

3. Page Data Extractor

Pulls structured data off any page: schema.org JSON-LD blocks, Open Graph tags, Twitter cards, hreflang, canonical, robots directives. Useful when you’re auditing a competitor’s content strategy or troubleshooting why a page isn’t getting rich results.

4. Brand Analyzer for Canva

Specifically for designers and marketers working in Canva. Inspects the brand kit usage on the current design — flags colour drift, typography inconsistencies, and identifies which shared assets the team is and isn’t using. Built after watching too many clients ship Canva designs that ignored their own brand guidelines.

5. Tag & Cookie Sentinel

Inspects every analytics, advertising, and tracking pixel firing on a page. Shows what’s set with consent, what fires before consent, what’s misconfigured, and which scripts have privacy-impact issues under Australian Privacy Principles. Pair it with a real audit before launching Google Ads or Meta campaigns.

6. Site Layout Inspector

Visualises the layout grid, container widths, and CSS box model directly on the page without needing DevTools open. Useful for content writers and marketers who want to understand why a CTA isn’t sitting where it should — without learning Chrome DevTools.

7. AI Prompt Library — Prompt Manager for ChatGPT and Claude

Saves and organises your prompts across ChatGPT, Claude, Gemini, and other LLM chat surfaces. Tag-based folders, one-click insertion, optional sharing inside a team. We built it for our own content team and ended up using it across the agency.

Why we made these free

Every Sydney small business owner we work with has the same problem: too many SaaS subscriptions, none of which they fully use. We don’t want to be another one. The extensions above are tools we needed for our own client work; releasing them costs us nothing and makes the work better for everyone.

If you’re running a Hills District or Western Sydney business and aren’t sure which of these would help most, the simplest test is to run SEO Snapshot and Website Health Auditor on your homepage. The output usually surfaces three or four ten-minute fixes that move your Google rankings inside a fortnight.

If those audits surface bigger work — Core Web Vitals failures, missing schema, accessibility gaps that block conversions — that’s the kind of project we do daily. Book a free 30-minute consultation and we’ll walk through your audit results.

Your website’s performance depends on what’s behind it. Cloud Geeks provides the managed hosting, cloud, and IT support that keeps Australian SMBs online and secure.

Ash Ganda covers how Australian SMBs are using AI, automation, and digital strategy to grow without scaling costs proportionally.

If your business is also planning a customer-facing iOS or Android app — Awesome Apps builds cross-platform mobile apps for Australian SMBs.

Part of the Ganda Tech Services family, Cosmos Web Tech delivers specialist web design and digital marketing for Australian small and medium businesses.

Frequently Asked Questions

Are these extensions really free? Yes. No signup, no email gate, no upgrade prompts. Install from the Chrome Web Store, run them. We may add paid features later for agencies and power users, but the audit and inspection features will always be free.

Do these extensions track my browsing? No. The extensions only execute on the page when you click their icon (or, for SEO Snapshot, when you trigger an audit). No background telemetry, no analytics on the user side. Each extension’s privacy policy is published in the Chrome Web Store listing.

Will they work on Wix / Shopify / Squarespace sites? Yes — they inspect rendered HTML and runtime data, so the underlying CMS doesn’t matter. A few advanced features (e.g. live schema preview) work better on server-rendered sites than fully client-side React SPAs, but the core audits run anywhere.

Can I request features? Yes — each extension’s listing has a support email. We prioritise features that solve a problem for multiple Australian SMB users.

Do you build custom Chrome extensions for clients? Yes. The browser-extension stack we use for these tools is the same one we offer to clients who need internal-tools quickly built — typically agencies, SaaS teams, or operations departments needing data-pull or workflow-automation extensions.
