Running a website audit is one of the most important steps in improving your search visibility. Many businesses assume their website is performing well—until traffic drops, rankings decline, or leads slow down. That’s when a proper SEO audit reveals hidden technical and on-page issues affecting performance.
If you’ve recently used a website audit tool and discovered errors, the next step is knowing how to fix them strategically. An audit report can look overwhelming, but most SEO issues fall into clear categories that can be resolved with a structured approach.
Let’s break down how to fix common SEO errors found in a website audit and restore your website’s ranking potential.
Step 1: Prioritise Critical Technical Errors First
Not all SEO errors carry the same weight. A good website audit tool will classify issues as critical, warnings, or notices. Start with critical technical problems because they directly affect your ability to rank.
Common Critical Issues:
- Pages not indexed by Google
- Broken internal links (404 errors)
- Missing or incorrect canonical tags
- HTTPS security issues
- Slow page speed
How to Fix Them:
- Submit updated XML sitemaps to Google Search Console.
- Redirect broken links using 301 redirects.
- Correct canonical tags to prevent duplicate content.
- Install an SSL certificate if missing.
- Optimise images, enable caching, and compress files to improve speed.
Without resolving technical foundations, your content may never reach its ranking potential.
Step 2: Fix On-Page SEO Errors
Once technical issues are handled, move to on-page improvements. These errors impact how well search engines understand your content.
Common On-Page Issues:
- Missing title tags or meta descriptions
- Duplicate title tags
- Keyword cannibalisation
- Missing H1 tags
- Thin or low-quality content
How to Fix Them:
- Write unique and keyword-optimised title tags for every page.
- Create compelling meta descriptions to improve click-through rates.
- Merge or restructure pages competing for the same keyword.
- Ensure every page has one clear H1 heading.
- Expand thin pages with informative, user-focused content.
A reliable website audit tool will flag these issues clearly, making it easier to prioritise updates.
Step 3: Improve Website Speed and Core Web Vitals
Page speed is a confirmed Google ranking factor. Many audit reports highlight slow-loading pages or poor Core Web Vitals scores.
Common Speed Problems:
- Large uncompressed images
- Excessive JavaScript
- Too many plugins
- Poor hosting environment
Fix Strategy:
- Compress images using modern formats (like WebP).
- Minify CSS and JavaScript files.
- Remove unnecessary plugins.
- Consider upgrading to faster hosting if needed.
Improving speed not only enhances rankings but also reduces bounce rates and improves conversions.
Step 4: Resolve Crawlability and Indexing Problems
If search engines cannot crawl your website properly, rankings will suffer regardless of content quality.
Audit Issues You May See:
- Blocked pages in robots.txt
- Noindex tags on important pages
- Orphan pages (not internally linked)
- Duplicate URLs
How to Fix:
- Review and update robots.txt carefully.
- Remove accidental noindex tags.
- Strengthen internal linking to ensure all pages are accessible.
- Consolidate duplicate URLs using canonical tags or redirects.
A good website audit tool highlights crawl errors clearly, allowing you to clean up your site structure efficiently.
Step 5: Strengthen Internal Linking Structure
Internal linking is often overlooked but plays a major role in SEO performance.
Common Internal Linking Errors:
- Too many broken links
- No links to high-value pages
- Over-optimised anchor text
- Pages with zero inbound links
How to Fix:
- Link strategically between related blog posts and service pages.
- Use descriptive, natural anchor text.
- Ensure priority pages receive more internal links.
- Update old content with new links.
This helps distribute authority across your website and improves keyword rankings.
Step 6: Address Duplicate and Thin Content
Duplicate content confuses search engines, while thin content reduces page authority.
Fix Strategy:
- Combine similar pages targeting the same keywords.
- Rewrite duplicate sections to make them unique.
- Expand short pages with valuable information.
- Add FAQs, examples, and supporting data to increase depth.
Your website audit tool may flag duplicate meta tags or content similarities—use this insight to clean up redundancy.
Step 7: Monitor Progress After Fixing Errors
Fixing SEO issues is not a one-time activity. After making improvements:
- Re-run your website audit tool to verify fixes.
- Monitor traffic trends.
- Track keyword performance.
- Review crawl reports in Google Search Console.
SEO improvements usually take a few weeks to reflect in rankings, so patience and consistent monitoring are key.
Final Thoughts
A website audit is only valuable if action follows insight. Identifying errors is the first step; systematically fixing them is what drives real ranking improvements.
By prioritising technical issues, strengthening on-page elements, improving speed, resolving crawl errors, and refining internal links, you create a solid SEO foundation.
Using a reliable website audit tool regularly ensures that your website remains technically healthy and search-engine friendly. Instead of reacting to ranking drops, proactive audits allow you to prevent issues before they impact visibility.
Ultimately, SEO success isn’t about avoiding errors entirely—it’s about identifying them early and fixing them strategically for long-term growth.
