Before diving into deep SEO work, it’s important to understand the general state of your website. This initial overview helps you see where strengths, weaknesses, and opportunities are hiding.
- Take a broad look at how your website currently performs in search results.

On-Page Optimization Techniques in How to Do an SEO Audit
On-page optimization is one of the most important parts of understanding how to do an SEO audit, because it gives you control over everything users see and search engines read. Strengthening these on-page elements helps you improve visibility, engagement, and overall ranking stability.
1. Review Title Tags
Title tags signal the core idea of a page to both users and search engines. Making them clear and keyword-focused improves click-through rates.
- Check whether each page has a unique, descriptive title tag.

2. Improve Meta Descriptions
Meta descriptions help users decide whether to click your page in the search results. Compelling copy boosts engagement and organic traffic.
- Ensure descriptions summarize the content clearly and attractively.

3. Optimize Header Structure (H1, H2, H3)
Headers guide readers through your content and help search engines understand your page hierarchy.
- Confirm each page has only one H1 tag.
- Use H2s and H3s to break content into logical, readable sections.
4. Strengthen Content Quality
Good content keeps visitors engaged and encourages them to explore more pages. This increases session duration and improves ranking signals.
- Ensure content answers user intent in a clear, helpful way.

5. Incorporate Keyword Placement
Strategic keyword placement helps search engines understand relevance without sounding unnatural.
- Include keywords in the intro, headers, and conclusion where appropriate.

Internal links guide users and search engines to related content. This increases page authority and improves crawlability.

Images can enhance user experience but require proper optimization for SEO benefits.

CTAs help guide users toward conversions, whether it’s reading another page, signing up, or making a purchase.
- Place CTAs naturally within the content path.
- Ensure buttons or links are easy to see and clearly worded.
Technical Factors to Review When Learning How to Do an SEO Audit
Technical SEO provides the foundation of a website’s search efficacy. Even if your content is strong, technical issues can prevent search engines from crawling, indexing, and ranking your pages properly. Understanding these factors is essential when learning how to do an SEO audit effectively.
1. Inspect Website Speed & Performance
A slower website irritates users and sends negative signals to search engines. Improving load time boosts visibility and engagement.
- Test your website using tools like PageSpeed Insights or GTmetrix.
- Optimize large files, unnecessary scripts, and heavy plugins.
2. Check Mobile-Friendliness
Google prioritizes mobile-first indexing, so a website that doesn’t function well on mobile devices risks lower rankings.
- Verify mobile responsiveness using Google’s Mobile-Friendly Test.
- Fix layout issues, tap targets, and text sizing.
3. Examine Crawl Errors
Crawl errors prevent search engines from accessing your content. Fixing them improves crawlability and ensures your best pages get discovered.
- Review your crawl report in Google Search Console.
- Address server errors, DNS issues, and blocked resources.
4. Review XML Sitemap Health
Your sitemap helps search engines understand your site structure and find important pages quickly.
- Ensure your sitemap contains only live, index-worthy URLs.
- Submit the sitemap to Google and Bing for better crawling.
5. Analyze Robots.txt Configuration
A misconfigured robots.txt file can accidentally block important pages from search engines.
- Check for “disallow” rules that may block essential content.
- Ensure your sitemap is properly referenced within the file.
6. Inspect HTTPS & Security Settings
Search engines favor secure websites because they protect user data and provide safer browsing experiences.
- Make sure your site uses HTTPS across all pages.
- Fix mixed-content errors caused by insecure scripts or images.
7. Audit Core Web Vitals
Core Web Vitals measure loading speed, responsiveness, and visual stability — all key ranking factors.
- Review LCP, FID, and CLS metrics in Search Console.
- Optimize slow-loading elements, layout shifts, and interaction delays.
8. Check Canonicalization
Canonical tags prevent duplicate content issues and ensure search engines index the correct page version.
- Add canonical tags to similar or duplicate pages.
- Avoid multiple pages competing for the same keyword.
9. Evaluate Structured Data Markup
Structured data helps search engines understand your content more clearly, often resulting in rich results.
- Use schema markup for products, articles, FAQs, reviews, and more.
- Test your markup using Google’s Rich Results Test.
10. Identify Broken Links & Redirect Chains
Broken links disrupt the user journey, while redirect chains slow down loading and waste crawl budget.
- Locate and fix 404 errors and redirect loops.
- Replace or update outdated links across your website.
Backlink & Off-Page Evaluation in How to Do an SEO Audit
Off-page SEO is a powerful part of learning how to do an SEO audit, because it reflects how other websites view and trust your content. Strong backlinks, brand signals, and online authority help search engines understand your site’s credibility and relevance.
1. Analyze Backlink Quality
Not all backlinks are created equal. High-quality, relevant links strengthen your site’s authority, while spammy links can damage it.
- Review your backlink profile using tools like Ahrefs or SEMrush.
- Identify authoritative links from credible websites in your industry.
2. Check for Toxic or Spam Links
Toxic links come from suspicious, irrelevant, or automated sources. Leaving them unchecked can lead to ranking penalties.
- Detect links from low-quality domains, link farms, or shady directories.
- Use Google’s disavow tool if harmful links cannot be removed.
3. Evaluate Anchor Text Diversity
Anchor text communicates context to search engines. Over-optimized anchors can look manipulative, while natural anchors support credibility.
- Ensure your anchor text contains a healthy mix of branded, generic, and keyword variations.
- Avoid repeating a single keyword phrase excessively.
4. Study Competitor Backlinks
Understanding where your competitors earn links helps you discover new opportunities for your own site.
- Analyze backlinks pointing to your top-ranking competitors.

5. Review Brand Mentions
Brand mentions — even unlinked ones — contribute to your online authority and credibility.
- Track online mentions of your brand on blogs, forums, and social platforms.
- Request a link wherever an unlinked brand mention appears.
6. Inspect Social Media Signals
Social media doesn’t directly influence ranking, but strong engagement amplifies visibility and traffic.
- Verify the frequency of discussion or sharing of your content.
- Strengthen presence on platforms where your audience already interacts.
7. Evaluate Referral Traffic
Referral traffic shows how effectively external websites send visitors to your site.
- Review which backlinks bring the most valuable visits.
- Strengthen relationships with sites that drive consistent referral traffic.
8. Check for Link Velocity
Link velocity refers to how naturally and consistently your site gains backlinks. Sudden spikes can signal manipulation.
- Assess whether new links appear steadily over time.
- Avoid link-building methods that create unnatural growth.
9. Identify Missing Authority Sources
Industry-trusted platforms, directories, and publications boost authority when they link to your site.
- Look for niche-specific websites you haven’t targeted yet.
- Build relationships with credible industry communities.
10. Build a Future Off-Page Strategy
Based on your backlink audit, you can map out a stronger visibility plan. Prioritizing quality over quantity leads to long-term stability.
- Focus on creating link-worthy content like guides, research, or tools.
