How to Do a Deep SEO Audit (Steal My SEO Audit Checklist)

Technical SEO: Core Website Setup

Having a well-structured technical setup helps search engines effectively find and trust your website. This directly impacts your site’s visibility and ability to convert visitors. Here’s what you need to focus on.

Search Engine Access

• Robots.txt Configuration: Check that your file doesn’t accidentally block important directories or resources. Misconfigured directives can limit access to your content.
• XML Sitemap: Make sure your sitemap is properly formatted, up to date, and submitted to search engines. Remove any broken or outdated URLs.
• Index Coverage: Use the Google Search Console Coverage report to identify pages that aren’t indexed or are orphaned, so you can address any issues.

Once this is in place, it’s time to evaluate your site’s mobile usability and speed.

Mobile and Speed Tests

• Responsive Design: Ensure your site’s layout adjusts seamlessly across all screen sizes.
• Touch Elements & Fonts: Confirm that buttons, links, and text are easy to interact with on mobile devices. Spacing and font sizes should support readability.
• Viewport Configuration: Double-check your meta viewport settings to ensure proper rendering on mobile devices.

Core Web Vitals are essential for measuring user experience. Focus on these metrics:

• Largest Contentful Paint (LCP): Aim for under 2.5 seconds (good). Between 2.5 and 4 seconds needs improvement, and anything over 4 seconds is poor.
• First Input Delay (FID): Keep it under 100 milliseconds. Between 100 and 300 milliseconds needs improvement, and over 300 milliseconds is poor.
• Cumulative Layout Shift (CLS): Target a score below 0.1. Scores between 0.1 and 0.25 need improvement, and anything above 0.25 is poor.

Finally, prioritize security to protect user data and maintain trust.

SSL and Security

• HTTPS: Ensure your SSL certificate is correctly installed. Fix any mixed-content warnings and enforce HTTPS redirects across your site.
• Security Headers: Add headers like Content-Security-Policy, X-Frame-Options, X-Content-Type-Options, and Strict-Transport-Security to enhance your site’s protection against potential threats.

On-Page SEO: Content and HTML Elements

Once your technical setup is solid, it’s time to refine on-page elements. This step ensures your content is relevant to search engines and clear for users.

Keywords and Meta Tags

Meta elements play a big role in signaling relevance to search engines:

• Title Tags: Keep titles between 50-60 characters and place the primary keyword at the beginning.
• Meta Descriptions: Aim for 140-160 characters. Include your target keyword and a clear call to action to encourage clicks.
• Header Tags: Use H1 for the main topic, and structure subheaders (H2-H6) with related terms and phrases.

Avoid keyword stuffing; instead, use related terms naturally. Google Search Console can help identify keywords that drive traffic to your site.

URLs and Site Links

A clean URL structure helps both users and search engines navigate your site efficiently:

• URL Format: Stick to short, descriptive URLs separated by hyphens. Avoid using unnecessary parameters.
• Breadcrumb Navigation: Add schema markup to breadcrumbs to clarify your site’s structure for both users and search engines.
• Internal Linking: Make sure all pages are accessible within 3-4 clicks. Don’t forget to link to pages that might otherwise be overlooked.

Image Setup

Optimizing images improves both performance and accessibility:

• Use file names that are descriptive and separated by hyphens.
• Write alt text that clearly describes the image and its purpose.
• Compress images to keep file sizes under 200 KB.
• Serve responsive images using srcset and next-gen formats like WebP. Use lazy-loading for off-screen images to improve page speed.

Off-Page SEO: Links and Online Presence

Once you’ve optimized your on-page elements, it’s time to focus on off-page factors that influence your site’s authority and visibility.

Off-page signals play a big role in determining how your site ranks and how authoritative it appears. Assess these factors to identify both opportunities and potential risks.

Backlink Quality Check

Take a close look at your backlink profile to identify useful links and weed out harmful ones:

• Link Profile Health: Look for unusual spikes or drops in links. Maintain a balanced mix of dofollow and nofollow links to keep things natural.
• Domain Authority Distribution: Check the authority of referring domains. It’s ideal to have a mix of high-, mid-, and low-authority links within your industry.
• Anchor Text Diversity: Avoid over-optimization by using a variety of anchor text types – brand names, generic terms, and partial-match keywords.

Be on the lookout for these warning signs:

• Multiple links coming from the same IP range
• Links from sites that are irrelevant to your niche or region, including sitewide links
• Pages overloaded with outbound links

Brand Mentions and Citations

Your brand’s presence online extends beyond just backlinks. Monitoring mentions and citations is key.

• Business Listings: Ensure your NAP (Name, Address, Phone) information is consistent across all directories. Keep your Google Business Profile and any industry-specific listings up-to-date.
• Review Management: Pay attention to reviews on major platforms. Respond thoughtfully and look for recurring themes in feedback.
• Social Signals: Track mentions of your brand, shares, and hashtags. Engage with influential users who are already talking about your business.

From here, you can move on to reviewing your content strategy to identify keyword gaps and better align with what your audience is searching for.

Content Strategy: Topics and Keywords

Once you’ve evaluated your site’s authority and backlinks, it’s time to focus on aligning your content with what users are searching for. A well-thought-out strategy ensures you’re targeting the right topics and filling any gaps in your coverage.

Keyword Analysis

• Pinpoint keywords with strong potential by looking at search volume, competition, and how they align with your business goals.
• Match your existing content to target keywords, identifying any overlaps or cases where your pages might compete with each other.
• Use tools like Google Search Console to track keyword performance trends and adjust your strategy as needed.

Reviewing Missing Content

• Study your competitors to uncover topics they’ve covered that you haven’t yet addressed.
• Identify pages on your site that are thin or outdated and could benefit from updates or additional details.
• Highlight any missing hub pages that could help establish your site as an authority on a specific topic.

Filling these gaps doesn’t just improve your relevance – it also increases the value of the backlinks you’ve worked hard to audit.

User Experience: Site Usability

Once your content strategy is in place, it’s time to assess your site’s navigation and user behavior. This ensures visitors can easily find what they need, leading to better engagement and improved search rankings.

Website Navigation

Your website’s navigation should make it simple for users to locate the content they’re looking for. Here’s how to make it happen:

• Organize menus in a clear, logical hierarchy that mirrors your content structure.
• Use consistent navigation patterns across all pages.
• Design clear and visually distinct calls-to-action (CTAs).
• Include a sitemap to provide a complete overview of your site’s structure.

Good navigation not only improves user experience but also helps search engines understand how your site is organized and how pages relate to each other.

User Behavior Data

Studying how visitors interact with your site can uncover areas for improvement and highlight what’s already working. Pay attention to these metrics:

• Bounce rate over 70%: Check if content matches user intent and ensure faster load times.
• Time on page under 30 seconds: Make content more engaging and detailed.
• High-exit pages: Add stronger CTAs or links to related content.
• Scroll depth below 50%: Reorganize content or include interactive elements to keep users engaged.

Key areas to track include:

• Differences in behavior between mobile and desktop users.
• Navigation paths that frequently result in conversions.
• Entry points beyond your homepage.
• Pages where users drop off during forms or cart processes.
• Content sections that consistently capture attention.

Heat mapping tools can be incredibly useful here. They show where users click and how far they scroll, helping you pinpoint distracting elements to remove or overlooked content to highlight. This data can guide adjustments that make your site more user-friendly and effective.
