Search Engine Optimisation audits are like a health check-up for your website. They identify technical issues, improve search rankings, enhance user experience, and ensure your site meets Google’s standards. Here’s why they matter:

Fix Website Problems: Spot and resolve issues like slow page speeds, duplicate content, and broken links.

Comprehensive SEO Audit Guide: Perfect for Beginners!

1. Find and Fix Website Problems

Technical issues can quietly undermine your website’s performance, affecting traffic and conversions without you even realising it. SEO audits work like a diagnostic tool, uncovering hidden problems that need attention.

One critical issue is website speed. Studies reveal that a 1-second delay in page load time can lead to 11% fewer page views, a 16% drop in customer satisfaction, and a 7% loss in conversions.

Even worse, 53% of mobile users will leave a site if it takes longer than three seconds to load. Daniel Cheung, SEO manager at Optus, puts it this way:

“As consumers are becoming more time‐poor and attention spans are decreasing, pages that don’t load immediately can mean that a customer will refuse to purchase from [that] site.”

A detailed technical SEO audit often highlights these common issues:

Duplicate Content: Up to 29% of web content is duplicated, which can confuse search engines and dilute your authority. Jenny Halasz, Head of SEO at LL Flooring, shares her experience:
“I have seen very successful websites stymied by duplicate content. In these cases, fixing the issues that lead to duplicate content alone can often result in a 20% or higher increase in organic traffic. When you have millions of visitors, that can be hundreds of thousands in additional revenue.”
Page Speed Issues: Audits identify what’s slowing your site down, like unoptimised images, unminified JavaScript and CSS, poor browser caching, or slow server responses.
Mobile Performance: With most users browsing on mobile devices, ensuring your site works seamlessly across all screen sizes is crucial. Audits help pinpoint mobile-specific problems that might hurt your rankings.
Technical SEO Errors: Issues like broken links, crawl errors, or missing meta tags can prevent search engines from properly indexing your site.

Diona Kidd, managing partner at Knowmad Digital Marketing, highlights the importance of speed:

“Users expect to see results quickly, and become disappointed when they don’t, but page speed also immediately affects their professional opinion of you.”

Addressing these problems not only boosts your search rankings but also creates a better experience for your visitors.

2. Improve Search Engine Rankings

Search engine rankings are key to your website’s visibility and growth. Over 90% of search traffic comes from the first page of results, with more than 50% focused on the top two organic positions. Clearly, ranking well in Perth is critical.

“Every search engine query displays a different set of signals that define which websites can rank on the search results pages and what their rank should be. The core of why SEO audit is important lies in their ability to ensure your website aligns with search engine algorithms and ranking factors.”

SEO audits play a crucial role in improving rankings by addressing technical issues and refining content strategies.

Technical Optimisation

SEO audits help identify and resolve problems like:

Slow page load times
Incorrect or missing meta tags
Broken links
Mobile compatibility issues (important since over 50% of global traffic is mobile)
Poor site structure

Content Quality Assessment

They also evaluate and enhance content by focusing on:

Proper keyword usage
Keeping content updated
Optimising header tags and meta descriptions
Strengthening internal linking

For local businesses, these improvements are especially impactful. With 46% of Google searches having local intent and 88% of smartphone users visiting a store within a week of a local search, optimising for local rankings can directly boost customer engagement.

“SEO audits are essential for any website to succeed in the long run. As search engine algorithms constantly evolve, what worked yesterday might not be as effective today.”

To keep rankings strong, experts suggest conducting audits regularly – either quarterly or monthly. This helps avoid sudden ranking drops and ensures your site stays aligned with the latest SEO standards.

It’s also worth noting that nearly 60% of sites in Google’s top ten have been around for three or more years, proving the value of consistent, long-term SEO efforts.

3. Make Websites Better for Users

User experience plays a key role in how visitors interact with and stay on a site. SEO audits help pinpoint and address issues that can frustrate users, leading to better site performance and engagement.

Speed and Performance

Did you know that websites taking more than three seconds to load lose 53% of mobile users? If load times stretch to five seconds, page views drop by 35%, conversions fall by 38%, and bounce rates double.

“Regular SEO audits improve your site’s visibility, usability, and performance. Fixing slow-loading pages or broken links can prevent users from bouncing, or leaving your website, directly impacting SEO rankings.”

Mobile Experience

A strong mobile experience ensures your site works smoothly on any device. This includes responsive design, touch-friendly navigation, and fast-loading images. Key elements include:

Responsive layouts that adjust to different screen sizes
Navigation designed for touch interaction
Text that’s easy to read without the need for side-to-side scrolling

A well-organised site makes it easy for users to find what they need. SEO audits focus on improving navigation elements like these:

Navigation Element	Purpose	Impact on User Experience
Clear Hierarchy	Logical organisation of content	Helps users locate information easily
Internal Links	Connecting related content	Simplifies navigation between pages
Breadcrumbs	Showing the current location	Enhances site orientation
Search Function	Quick access to specific content	Speeds up finding information

Good structure not only helps users but also supports engaging content that keeps them on your site longer. Strong internal linking strategy also helps guide users and distributes link equity across your site.

Content Readability

Readable content is just as important as smooth navigation. SEO audits check for text formatting, effective use of headers, clear paragraph structure, and content relevance.

“They also heavily factor in your website’s user experience. By providing both new and recurring visitors with a seamless and pleasurable website experience, you can naturally improve your SEO.”

Accessibility

Accessibility ensures that everyone can use your website effectively. SEO audits now review elements like:

Adequate color contrast
Descriptive alt text for images
Properly structured headings
Support for keyboard navigation

Keeping accessibility features updated is crucial as user needs evolve. With 82% of B2B pages loading in five seconds or less, staying competitive means maintaining strong performance. Improved accessibility not only benefits all users but also boosts your overall SEO efforts.

4. Meet Google’s Website Standards

After addressing technical issues and improving user experience, the next step is aligning with Google’s website standards. Regular SEO audits play a key role in ensuring your site meets these criteria and avoids penalties.

Technical Requirements

Here are some key technical elements to focus on:

Requirement	Purpose	Impact on Rankings
200 HTTP Status	Confirms pages are live and accessible	Crucial for indexing
Crawlability	Ensures Google can find your content	Necessary for visibility
Mobile-first Design	Optimises site display across devices	Direct ranking factor
HTTPS Security	Protects user information	Builds trust with users

Quality Guidelines

SEO audits are also essential for identifying practices that might violate Google’s quality standards. With over 8.5 billion searches happening on Google every day, staying compliant is key to staying visible in search results.

To understand exactly what Google expects and how to stay compliant, check our in-depth Google compliance audit guide.

Common Violations to Check

When conducting an SEO audit, watch out for these problematic practices:

Cloaking: Showing different content to users than to search engines.
Keyword Stuffing: Overloading pages with keywords, making content awkward or unnatural.
Link Schemes: Using artificial link-building methods to manipulate rankings— especially if you’re using risky providers. Here’s why cheap link building services can backfire.
Auto-Generated Content: Publishing low-quality, automated content.

Fixing these issues not only helps avoid penalties but also opens the door to better performance.

Proven Results

Take Verint‘s platform as an example. After an SEO audit, the company saw a 210% increase in non-branded organic search clicks and a 33% growth in top-10 keyword rankings.

Algorithm Updates

Google updates its algorithm hundreds of times a year and factors in over 200 ranking signals. SEO audits help you stay aligned with these changes, ensuring your site remains competitive and takes advantage of opportunities to improve visibility with high-quality content.

5. Find Missing Content Topics

SEO audits can uncover gaps in your content that, when addressed, can improve your site’s visibility. For local searches, having content tailored to your area is especially important.

This analysis complements technical fixes and user experience updates, helping round out your SEO strategy.

Common Types of Content Gaps

Gap Type	Description	Impact on SEO
Content Freshness	Content that is outdated or stale	Hurts relevance and authority
Topic Coverage	Missing important subject areas	Limits keyword reach
Content Depth	Information that’s too shallow	Reduces user engagement
Local Context	Lack of local relevance	Weakens local search results

Filling these gaps is just as important as fixing technical SEO issues, making it a key part of improving your site’s overall performance.

Tools to Identify Gaps

Tools like Semrush‘s Keyword Gap and Google Search Console can help you find missing keywords and underperforming pages systematically.

A Real-Life Example

Backlinko tackled outdated content by creating Link Building: The Definitive Guide. This approach helped them rank in the top 3 for the term “link building”.

Opportunities in Local Content

For businesses focusing on specific geographic areas, content gaps often involve missing local details. Addressing these gaps can strengthen your local SEO efforts. Here are some ideas:

Add Local References: Mention landmarks, events, or community involvement.
Highlight Staff: Write detailed bios that connect your team to the local area.
Use Visuals: Include geo-tagged photos or videos that showcase your business.

Tips for Implementation

Analyse competitor keywords to find opportunities.
Keep your content updated with a regular publishing schedule.
Use examples and credible outbound links to make your content stronger.
Draft specific content briefs to directly address the gaps you identify.

6. Check Competitor Websites

Analysing competitor websites can reveal opportunities to boost your own site’s performance. While SEO audits focus on your internal site issues, competitor analysis helps you identify external growth areas. Here’s what to focus on.

Key Areas to Analyse

Analysis Area	What to Look For	Why It Matters
Google Business Profile	Reviews, photos, categories	Builds stronger local presence
Keywords	Rankings, content gaps	Highlights content opportunities
Backlinks	Quality sources, broken links	Opens link-building prospects
Local Citations	Directory listings, consistency	Boosts local search visibility
Technical SEO	Site speed, mobile optimisation	Benchmarks site performance
Ecommerce store SEO	Product schema, category page depth, product feed health	Improves product visibility in search and drives conversions

This includes ensuring NAP consistency when relocating — see our full guide to handling your Google Business Profile when relocating locally.

Google Business Profile Analysis

A well-optimised Google Business Profile is crucial for local SEO. Profiles with high-quality visuals see 42% more engagement and 35% more clicks. When analysing competitors, look at:

Business categories and attributes
Volume and quality of reviews
Photos, videos, and other visual content
Product and service descriptions
Customer engagement metrics

If your profile was suspended, a proper recovery plan matters just as much as competitor benchmarking. Learn more about Google Business Profile reinstatement.

Content and Keyword Strategy

Tools like Semrush can help you uncover what works for your competitors. Focus on:

Topics that rank well
Content length and structure
Local keyword integration
Seasonal content trends
User engagement with content

“Local competitor analysis is about learning from others’ successes and failures to improve your own strategy.”

Monitoring Tools and Metrics

Competitor monitoring tools simplify tracking their performance. As Connor Wilkins, CMO of Direction.com, puts it:

“Keep your friends close, and your competitors closer when it comes to local SEO – observing their strategies helps keep your tactics ahead of the curve.”

Implementation Tips

To gain an edge, focus on these strategies:

Track ranking shifts during seasonal events
Compare backlink acquisition rates
Examine local directory consistency
Assess how competitors respond to reviews
Evaluate their technical SEO practices

Competitor analysis isn’t about imitation – it’s about understanding industry benchmarks and finding ways to outshine them. Regular checks can help you stay ahead of trends and seize opportunities before your competitors do.

7. Get Better Results from Marketing

SEO audits play a key role in getting the most out of your marketing efforts. In fact, 91% of businesses report strong returns on investment after making audit-based updates to their digital strategies.

These results come from the detailed insights audits provide into your online presence.

How to Use Audit Insights Effectively

SEO audits provide actionable data for improving your marketing strategy. Here are two key areas to focus on:

Technical Optimisation

Tracking Your Results

After implementing changes, it’s crucial to measure their impact. Monitor key performance indicators (KPIs) like organic traffic, search rankings, conversion rates, revenue growth, and local search visibility. For e-commerce sites, aim to conduct audits every quarter. Smaller websites can benefit from audits twice a year.

Conclusion

Regular SEO audits are crucial for improving your website’s performance and increasing its visibility. With 93% of online experiences starting with a search engine, these audits not only help uncover issues but also provide actionable steps to enhance your site.

The Difference Professional SEO Audits Make

Professional audits go far beyond what DIY tools can achieve. While basic tools can spot surface-level problems, expert-led audits dive deeper and offer a more thorough evaluation:
