How to Audit Your Website SEO for Free

A No-BS Walkthrough Using Free Tools That Actually Find Problems

TL;DR: Running a basic SEO audit doesn't require expensive subscriptions. With free tools for broken link checking, schema markup, sitemap generation, keyword analysis, and meta tag previews, you can spot and fix the issues that tank your rankings.

Last year, a friend asked me to look at her small business website. She'd been blogging weekly for eight months and couldn't figure out why her traffic was flatlining. I pulled up her site, ran a few free checks, and found the problem in under ten minutes: 47 broken links, zero structured data, and meta descriptions that read like they were written by a robot having a bad day.

Why Free SEO Tools Are Enough for Most Sites

Premium SEO platforms like Ahrefs and SEMrush are incredible. They're also overkill for most small businesses, freelancers, and bloggers. If you're running a site with under 500 pages, free tools cover the essentials.

Step 1: Find and Fix Broken Links

Toolgami's Broken Link Checker crawls any webpage and lists every dead link it finds.

Quick fix workflow: Use the Redirect Checker to verify 301 redirects, then the HTACCESS Redirect Generator to create redirect rules.

Step 2: Check Your Website Status and Speed Signals

The Website Status Checker tells you if your site returns the right HTTP codes. Run a GZIP Compression Test to verify server compression.

The Image Compressor can cut image file sizes dramatically. I covered this in my post about compressing and converting images for faster websites.

Step 3: Analyze Your Keyword Strategy

The Keyword Density Analyzer breaks down which words and phrases dominate your page.

Step 4: Preview and Fix Your Meta Tags

The Meta Tag Preview tool shows how your page appears in Google results. Pair with the SEO Tags Generator, Twitter Card Generator, and Open Graph Preview tool.

Step 5: Add Structured Data (Schema Markup)

The Schema Markup Generator creates JSON-LD structured data for articles, FAQs, products, and more.

Step 6: Generate and Submit Your Sitemap

Toolgami's Sitemap Generator creates a valid XML sitemap. Don't forget the Robots.txt Generator.

Step 7: Check Your SSL and Security

The SSL Checker validates your certificate. My post on password security and online tools covers generating strong credentials.

Step 8: Verify Your DNS and Domain Health

The DNS Lookup tool shows your full DNS record set. The MX Lookup verifies email routing. The Domain WHOIS tool gives domain details. More in my post about troubleshooting network issues.

FAQ

How often should I run an SEO audit?
Monthly checks on broken links and meta tags. Full audit quarterly.

Can free tools replace Ahrefs or SEMrush?
For basic on-page SEO, yes. Paid tools excel at backlink analysis and rank tracking at scale.

What's the single most impactful free SEO fix?
Adding structured data markup. Most small sites don't have it.

Does Toolgami's Broken Link Checker work on large sites?
It checks individual pages. For large sites, run it on your most important pages first.

Is GZIP compression the same as image compression?
No. GZIP compresses server responses. Image compression reduces image file sizes. You want both.
