DIY SEO Audit Checklist Using Free Tools
Hiring an SEO agency costs thousands of dollars. But the foundational technical audit — the part that catches the most impactful issues — is something you can do yourself in under an hour. This guide walks you through a five-point SEO checklist using free browser-based tools. These are the same checks that agencies run first, and fixing the issues they reveal often produces the biggest ranking improvements.
Check 1: Meta Tags
Every page on your site needs a unique title tag (50–60 characters) and meta description (150–160 characters). These are what appear in Google search results, and they directly influence click-through rates. Use the Meta Tag Generator to create properly formatted tags for each page. The tool also generates Open Graph tags for social media sharing and Twitter Card markup. If your pages currently have missing or duplicate meta tags, this is one of the highest-impact fixes you can make.

Your robots.txt file tells search engines which pages to crawl and which to ignore. A misconfigured robots.txt can accidentally block your entire site from being indexed. Use the Robots.txt Generator to create a correct file or validate your existing one. Common mistakes include blocking CSS and JavaScript files (which prevents Google from rendering your pages properly) and forgetting to include your sitemap URL.
Check 3: Favicon
A favicon might seem cosmetic, but it affects SEO indirectly. Google displays favicons in mobile search results, and a missing favicon shows a generic globe icon that reduces trust and click-through rates. The Favicon Generator creates all required sizes from a single image: 16×16 for browser tabs, 32×32 for taskbars, 180×180 for Apple touch icons, and 192×192 for Android. Upload the files and add the meta tags to your site’s <head>.
Check 4: Site Speed
Page speed is a confirmed Google ranking factor. Slow pages also have higher bounce rates and lower conversion rates. Run your site through the Speed Test to measure load times and identify bottlenecks. Pay attention to the largest element on the page (Largest Contentful Paint) — if it takes more than 2.5 seconds to load, you need to optimize it. Often the biggest culprit is unoptimized images, which brings us to the final check.

Images typically account for 50–70% of a page’s total weight. If your speed test reveals slow loading, images are the first thing to fix. Use the Image Compressor to reduce every image on your site to its optimal size. Aim for under 100KB for inline blog images and under 200KB for hero banners. This single step can cut your page load time in half.

This checklist covers the technical SEO fundamentals. It will not write your content strategy or build backlinks, but it removes the barriers that prevent search engines from properly indexing and ranking the content you already have. Do it once, maintain it as you add new pages, and you will be ahead of most of your competitors.
