How to Run a 15-Minute SEO Audit (Free Checklist)
Full SEO audits can take hours and produce 50-page reports filled with technical jargon. Most small business owners do not need that. They need to know: is anything obviously broken, and what should I fix first?
This 15-minute audit covers the checks that catch the majority of real-world problems on small business websites. You do not need any paid tools — just Google Search Console, a browser, and this checklist.

Minute 1-3: Title Tags
Open your site and view the page source of your 5 most important pages (homepage, main service pages, top blog posts). Check the <title> tag for each.
What you are looking for:
- Each page has a unique title (not all saying the same thing)
- Titles include relevant keywords (not just your company name)
- Titles are under 60 characters (to avoid truncation in search results)
- No page has a generic title like "Home," "Services," or "Page 1"
Common problems found: Duplicate titles across pages, missing keywords, titles that are just the business name. See our title tag guide for examples of good vs bad titles.
How to check quickly: Google site:yourdomain.com and look at the titles shown in search results. This shows exactly what Google displays for each page.
Minute 3-5: Indexing Status
In GSC, go to Indexing > Pages.
What you are looking for:
- Your most important pages show as "Indexed"
- No critical pages are in the "Not indexed" categories
- The total indexed page count roughly matches the number of pages you expect
Common problems found: New pages not yet indexed, thin pages crawled but not indexed, important pages accidentally blocked. If you are unsure about specific pages, use the indexing check feature.
Minute 5-7: Mobile Experience
Open your site on your phone (or use Chrome DevTools mobile simulation).
What you are looking for:
- Text is readable without zooming
- Buttons and links are easy to tap (not too small or close together)
- No horizontal scrolling required
- The menu works on mobile
- Forms are usable on mobile
Common problems found: Text too small, tap targets too close, images wider than the screen, forms that break on mobile. See our mobile-friendly guide for fixes.
Minute 7-9: Page Speed
Page speed is a confirmed Google ranking factor and directly affects whether visitors stay or leave.
Test your homepage with Google's free PageSpeed Insights tool at pagespeed.web.dev.
What you are looking for:
- Core Web Vitals show "Good" (green) in the field data section
- LCP (Largest Contentful Paint) is under 2.5 seconds
- INP (Interaction to Next Paint) is under 200 milliseconds
- CLS (Cumulative Layout Shift) is under 0.1
- No critical issues flagged in the Diagnostics section
Common problems found: Oversized images, too many third-party scripts, render-blocking resources. The performance section of PageSpeed Insights lists specific issues with fix recommendations. See our guide on checking website speed.
Minute 9-11: Internal Links
Pick your most important service or product page. Check whether other pages on your site link to it.
What you are looking for:
- At least 3-5 internal links point to your most important pages
- Blog posts link to relevant service pages
- No important pages are "orphans" (zero internal links)
- Link text is descriptive (not "click here")
Common problems found: Service pages with no links from blog content, blog posts that link to nothing, orphan pages that Google can barely find.
Quick method: Google site:yourdomain.com "your service name" to find pages that mention your service. Each mention is a potential internal link.
Minute 11-13: Content Check
Open your 3 most important pages and evaluate the content.
What you are looking for:
- Each page has at least 300+ words of unique content
- Content answers the question a searcher would have
- Headings (H1, H2) are used to structure the content
- The page has a clear H1 that includes the target keyword
Common problems found: Thin service pages with only 50-100 words, missing H1 tags, content that describes the business but does not address what the searcher needs.
Minute 13-15: Google Search Console Errors
In GSC, quickly check three sections:
1. Security & Manual Actions — Should say "No issues detected." If it shows problems, these are urgent.
2. Experience > Core Web Vitals — Note how many pages are Poor vs Good.
3. Performance > Search Results — Look at the overall trend. Is organic traffic growing, flat, or declining? This is the most important SEO metric.
Your Results: What to Fix First
After the 15-minute audit, prioritize fixes in this order:
| Priority | Issue | Time to Fix |
|---|---|---|
| 1 | Security issues or manual actions | Immediate |
| 2 | Important pages not indexed | 1-2 hours |
| 3 | Generic or missing title tags | 30 minutes |
| 4 | Thin content on key pages | 1-2 hours per page |
| 5 | Missing internal links | 30-60 minutes |
| 6 | Mobile usability issues | Varies |
| 7 | Page speed problems | Varies |
The 80/20 rule applies: Title tags, indexing, and content quality account for the vast majority of SEO impact on small business sites. Fix those first and the technical details become marginal improvements.
For a more detailed analysis that cross-references your search data with page performance, connect your GSC and GA4 through Brass-SEO and ask "What should I work on first?" It prioritizes based on your actual data, not generic checklists. If you prefer using ChatGPT or Claude, the AI prompts guide for SEO includes a DIY audit checklist prompt you can run against any page.

Frequently Asked Questions
Is this audit as good as a professional SEO audit?
No, and it does not claim to be. A professional audit covers hundreds of technical factors, competitive analysis, backlink profiles, and content strategy. This 15-minute version catches the problems that affect most small business sites. Think of it as a health screening, not a full physical. If the screening finds something concerning, you can investigate deeper.
How often should I run this audit?
Run the full checklist quarterly. Between audits, do a monthly data check-in focused on traffic trends and keyword performance. The quarterly audit catches new problems that develop over time — new pages with thin content, changed title tags, or emerging speed issues.
What if everything passes?
Great — your site's fundamentals are solid. Next steps would be: look for striking-distance keywords to push to page 1, create new content targeting keyword gaps, and optimize existing top-performing content to maintain and grow traffic.
Can Brass-SEO automate this audit?
Brass-SEO automates several of these checks. It can tell you which pages get traffic, which have indexing issues, what keywords you rank for, and what opportunities you are missing. The manual checks (mobile experience, content quality review) still benefit from human judgment, but the data-driven portions are faster with AI assistance.
What if I find problems I cannot fix myself?
Title tag changes, content improvements, and internal linking are all doable without technical skills. Mobile issues, speed problems, and structural changes may need a developer. Start with what you can do — the biggest wins (titles, content, links) are non-technical.
