SEO Audit: How to Fix Your Website’s Technical SEO Issues

First-Time Setup Guide

Getting started with a proper setup is key to running accurate audits. Here’s how to set everything up step by step.

Starting a Project

You can create a project by importing data directly from Google Search Console (GSC) for faster setup, or you can opt for manual configuration.

For manual setup, here’s what you need to do:

Click the "+ New Project" button on your Ahrefs dashboard.
Define the scope of your project: a domain, subdomain, or specific path.
Verify ownership of the website.
Set up the initial audit parameters.

Once the project is created, make sure to adjust the crawl settings to suit your site.

Crawl Settings

Crawl settings play a big role in the accuracy of your audits. While the default settings work for most websites, you can tweak them for specific needs.

Setting Type	Recommended Configuration	Best For
JavaScript Rendering	Enabled	Single-page apps, dynamic content
Crawl Speed	Slow to Medium	Shared hosting or budget servers
URL Parameters	Custom regex filters	Large sites with specific sections
Authentication	Login details	Password-protected areas

"A project is any domain, subfolder, or URL that you want to track automatically over time." – Ahrefs

After configuring crawl settings, set up automated scans to ensure consistent monitoring.

Setting Up Regular Scans

To enable recurring crawls, navigate to the Schedule section in the Site Audit settings.

Here’s what to keep in mind:

Scan Frequency: For websites with frequent updates, schedule weekly scans. For static sites, monthly scans should suffice.
Time Selection: Choose off-peak hours to reduce server strain during scans.
Monitoring Setup: Enable the "Run scheduled Crawls" option to keep track of changes over time.

Keep in mind that any changes to these settings will only apply to future crawls, so take your long-term monitoring needs into account during the initial setup.

Reading Audit Results

To improve your site’s technical health, focus on three main areas: Health Score, Issue Types, and Crawl Data.

Health Score Explained

The Health Score measures your website’s technical SEO performance. It shows the percentage of internal URLs without errors.

Health Score Range	Rating	What It Means
91–100	Excellent	Your site has very few technical issues.
71–90	Good	Some fixes are needed, but overall it’s solid.
31–70	Fair	Major technical problems need addressing.
0–30	Weak	Critical issues require immediate action.

"Health Score reflects the proportion of internal URLs on your site that don’t have errors." – Ahrefs

Strive for a Health Score above 90 to keep your site running smoothly. Once you’ve checked this, move on to evaluating issue types.

Issue Types and Priority

Ahrefs organises technical SEO issues into three priority levels:

Errors (Red): These are critical and directly affect your Health Score. Examples include broken links, missing title tags, or duplicate content. Fix these first.
Warnings (Yellow): These don’t impact your Health Score but can still hurt SEO performance. Address these after resolving errors.
Notices (Blue): These are informational and may not require immediate action but are worth reviewing.

"The Technical SEO Audit is like an assessment of the foundation of a house. You can still live in a house without a great foundation, but eventually cracks will appear. If you don’t take care of your Technical SEO issues early, you might end up reducing the impact of other SEO efforts and limiting your potential growth." – Rodrigo Lasanta, Lead SEO Specialist

With your priorities clear, dive into your crawl data for deeper insights.

Crawl Data Overview

Crawl data reveals how search engines interact with your site. Focus on these key metrics:

Metric	Target/Goal	Why It Matters
Page Response Status	>80% OK	Ensures most pages are accessible.
Discovery Rate	>5%	Shows search engines are finding new pages.
Server Response Time	Fast	Faster responses improve crawl efficiency.

To make the most of this data:

Look for patterns in total crawl requests to spot issues.
Analyse server performance to ensure smooth operations.
Fix 404 errors and server issues promptly.
Confirm that your robots.txt file is accessible.

For detailed fixes, use the "Why and how to fix" feature in Ahrefs.

Fixing SEO Problems

Use the insights from your audit to address issues with indexing, linking, and performance. Here’s how to tackle these challenges step by step.

Page Indexing Fixes

Check the indexability report in Ahrefs Webmaster Tools (AWT) and focus on these key areas:

Canonical Tags: Replace incorrect canonical tags to prevent duplicate content issues.
Noindex Tags: Remove ‘noindex’ tags from pages you want search engines to index. Double-check your robots.txt file for accidental blocking.
Orphan Pages: Link pages that are isolated from the rest of your site. Strategic internal linking can help – see the next section for tips.

Once you’ve addressed these indexing issues, it’s time to refine your internal linking structure to strengthen your site’s authority.

Internal Link Structure

"Internal linking is super critical for SEO. It’s one of the biggest things you can do on a website to guide Google and visitors to the pages that you think are important." – Dorian, Perth SEO Expert.

To build an effective internal link structure, focus on these strategies:

Action Item	How to Do It	Why It Matters
Deep Linking	Link directly to specific content pages, not just the homepage	Boosts crawl depth and page authority
Anchor Text	Use clear, descriptive text for your links	Helps search engines understand context
Link Distribution	Ensure key pages are no more than 3–5 clicks from the homepage	Improves crawl efficiency

By improving your internal links, you make it easier for both users and search engines to navigate your site.

Speed and Web Vitals

Core Web Vitals are essential for both user experience and search rankings. Here’s a quick breakdown:

Metric	Target Score	Key Areas to Focus On
LCP (Largest Contentful Paint)	≤2.5 seconds	Prioritise loading critical resources, reduce file sizes
INP (Interaction to Next Paint)	≤200ms	Optimise JavaScript execution, split long tasks
CLS (Cumulative Layout Shift)	≤0.1	Reserve space for media, improve font loading

To improve these metrics:

Faster Loading (LCP): Host resources locally, enable caching, and compress files.
Better Interactivity (INP): Minimise JavaScript, use server-side rendering, and break up long-running tasks.
Visual Stability (CLS): Reserve space for dynamic elements, optimise fonts, and use layout-preserving animations.

Advanced Tools and Features

Beyond basic fixes, advanced tools and integrations allow for more precise optimisation and custom solutions. Here’s a closer look at how these features can improve your website’s performance.

Content Analysis

These tools help you dive deeper into your content strategy:

Analysis Feature	Purpose	Action Items
Duplicate Content Detection	Spot identical or overly similar content	Fix duplicate pages, titles, and meta descriptions
Content Gap Analysis	Identify missing subtopics	Research competitors and add relevant sections
Traffic Potential	Assess a page’s reach	Focus on optimising pages with the most growth potential

"Site Audit crawls all your website’s pages. It flags all possible technical and on-page SEO issues, provides recommendations on how to fix them, visualises key data in a chart, and delivers an overall SEO health score." – Ahrefs

Schema Markup Check

Structured data can improve how search engines interpret your site. Here’s how to ensure accuracy:

Validation Process: Use the "All issues" report to identify schema errors and prioritise fixes based on traffic impact.
Implementation Check: Validate schema using the Ahrefs SEO Toolbar and submit critical URLs through Google Search Console.

Tool Integration Tips

Integrating tools can simplify reporting and improve collaboration. Here are some useful pairings:

Integration Type	Recommended Tools	Key Benefits
Analytics	Google Analytics, Adobe Analytics	Link search traffic data with user behavior
Rank Tracking	SERPWatcher, Rank Tracker	Keep tabs on keyword ranking changes
Technical SEO	Screaming Frog, Sitechecker	Boost crawling and error detection capabilities
Data Visualisation	Google Data Studio, Tableau	Build custom SEO dashboards

For even greater efficiency, use the Ahrefs API to automate data workflows. Connect Ahrefs with tools like Asana or Trello to track SEO tasks and improve team coordination.

Website Maintenance Guide

After fixing technical errors, keeping your site healthy requires consistent effort and organisation.

Issue Management

Ahrefs helps you manage technical SEO issues using three priority levels:

Priority Level	Description
Errors (Red)	Critical problems that impact SEO
Warnings (Yellow)	Issues that need attention but aren’t urgent
Notices (Blue)	Minor updates or informational suggestions

Enable the Always-on audit to catch issues in real time and get instant alerts. With Data Explorer, you can:

Generate detailed issue reports
Create task lists for developers
Track the progress of fixes
Log the dates when issues are resolved

Progress Monitoring

Your website’s Health Score reflects the percentage of internal URLs without errors – think of it as your site’s overall "health check."

Automated Audits: Schedule weekly crawls to spot trends and prevent problems early.

Segment Analysis: Break your site into sections and monitor specific metrics:

Website Section	Focus Area	Key Metrics
Product Pages	Schema markup, pricing	HTTP status, load time
Blog Content	Internal links, metadata	Traffic potential, depth
Landing Pages	Core Web Vitals	Performance scores

Historical Tracking: Use crawl history to see how your website evolves over time. Track new pages, resolved issues, page updates, and shifts in your health score.

These steps help ensure your fixes stick and your site stays optimised.

Team Coordination

Ahrefs Site Audit makes teamwork easier with role-based access:

Role	Permissions	Responsibilities
Workspace Admin	Full access	Strategy and oversight
Members	Project-specific access	Implement fixes
Guests	View-only access	Reporting and monitoring

Assign roles, prioritise tasks, set deadlines, and hold weekly reviews. Export categorised issues to simplify handoffs. This structured approach keeps everyone aligned and on track.
