SEO-site audit – how to do it yourself

You have invested in creating a website, filled it with content, but there is no traffic and no inquiries. Why? Perhaps your site is poorly indexed, loads too slowly, or contains low-quality content. Or maybe it has toxic backlinks that lower its search rankings.

But search engine algorithms change, and competitors don’t stand still. Even if your site brought in customers a year ago, today it may be losing traffic due to hidden issues.

Agencies charge thousands of dollars for it, but you can do the audit yourself. The key is knowing what and how to check.

In this article, I will provide you with a step-by-step SEO audit checklist that will help you:

• Identify errors that hinder promotion.
• Improve indexing and loading speed.
• Optimize content and technical parameters.
• Boost search rankings without unnecessary costs.

What is an SEO Audit?

Simply put, it is a diagnostic process that helps you understand why your site isn’t attracting traffic and what is obstructing its effective promotion.

However, in reality, search algorithms constantly change, competitors enhance their websites, and issues accumulate unnoticed. As a result, traffic declines, rankings drop, and potential customers go to competitors.

Who Needs an SEO Audit?

• Entrepreneurs who want to increase client flow through their website but don’t understand why it’s not delivering results.
• Marketers who need to assess the current SEO strategy and identify weak points.
• SEO specialists who refine optimization strategies to achieve better search results.
• E-commerce site owners who rely on organic traffic and want to boost sales.

What Issues Does an SEO Audit Reveal?

• Poor page indexing – search engines don’t see important site sections, so they don’t appear in search results.
• Technical errors – slow loading, broken links, incorrect redirects, and coding issues.
• Content problems – duplicate texts, weak headlines, and non-unique meta tags.
• Weak backlink profile – lack of quality external links or the presence of toxic domains.
• Usability (UX) issues – inconvenient navigation, complex forms, and high bounce rates.

Conducting an SEO audit helps eliminate critical errors and optimize your site for better indexing, faster loading, and higher search rankings.

Types of SEO Audits: What Should You Check?

An SEO audit is not just a routine site check; it’s an in-depth analysis that reveals why your website isn’t bringing in customers and what’s stopping it from reaching the top rankings. Based on BUSINESS SITE’s experience, most issues lie deeper than they initially seem.

An SEO audit consists of four key areas:

1. Technical audit – checks loading speed, indexing, and URL structure.
2. Content audit – analyzes text, headlines, and duplicate content.
3. Backlink profile analysis – evaluates the quality and quantity of internal and external links.
4. UX audit – assesses user behavior and site usability.

Let’s go through each of these steps using real-life case studies.

Technical Audit: If Your Site Is “Heavy,” Google Won’t See It

What Do We Check?

• Loading speed – the time it takes for a site to fully load for users. Affects UX and ranking. Can be checked with Google PageSpeed Insights and GTmetrix.
• Page indexing – the process by which search engines add pages to their database. Indexing errors can prevent pages from appearing in search results. Analyzed via Google Search Console.
• 404 errors and 301 redirects – broken links (404) disrupt user experience and SEO, while 301 redirects help maintain rankings when pages are moved.
• Robots.txt and sitemap.xml – robots.txt manages search engine access to pages, while sitemap.xml helps them find important site sections faster.
• Mobile-friendliness – ensures the site displays correctly on smartphones and tablets. Checked using Google Mobile-Friendly Test.
• Code cleanliness – avoids duplicate elements, unnecessary scripts, and excess HTML code, which can slow down the site and cause indexing errors.

Case Study:

Client: an online home appliance store.

Problem: slow site loading, declining traffic from Google.

Our audit revealed critical issues:

• Homepage size – 6 MB (due to uncompressed images).
• All pages were redirected using a 302 redirect (Google wasn’t indexing the new site).
• Gzip compression was disabled, causing pages to load in over 5 seconds.

Solution:

• Optimized images (converted to WebP, compressed files).
• Fixed redirects by switching to 301 (so Google would recognize them).
• Enabled caching and gzip compression.

Results:

• Loading speed decreased from 5.8 sec to 1.3 sec.
• Indexing errors disappeared from Google Search Console.
• Traffic increased by 35% in two months.

How to Perform a Technical Audit Yourself:

• Check indexing in Google Search Console.
• Ensure there are no 404 errors.
• Check robots.txt (to ensure it isn’t blocking important pages).
• Update sitemap.xml and submit it to Google.
• Analyze loading speed with Google PageSpeed Insights.
• Test mobile-friendliness with Google Mobile-Friendly Test.

Tools for Technical SEO Audits:

• Google Search Console – indexing and error tracking.
• Screaming Frog SEO Spider – site structure analysis.
• GTmetrix, PageSpeed Insights – loading speed analysis.
• Ahrefs, SEMrush – technical analysis.

Content Audit: If Your Texts Don’t Work

What Do We Check?

• Headings (Title, H1-H6) and meta descriptions – structure content and help search engines understand its essence. The Title tag affects click-through rates (CTR), while H1-H6 headings form content hierarchy.
• Duplicate content – repeated or similar texts across pages that can cause search engines to lower site rankings.
• Content uniqueness – percentage of original content. Non-unique texts reduce rankings as search engines prioritize the original source.
• Canonical URLs – a special tag that tells search engines which page version is primary, preventing duplicate content issues.
• Readability and keyword relevance – how easy content is to read and how well it matches user search queries.

Case Study:

Client: a legal services website.

Problem: low rankings, few inquiries, low CTR in search results.

Our audit revealed:

• Duplicate Title tags on 80% of pages.
• Texts were generic, lacking relevant keywords.
• Poor content structure – long blocks of text without subheadings or lists.
• CTR in search results was below 1% – users weren’t clicking.

Solution:

• Rewrote Title tags with relevant keywords and unique selling points.
• Rewrote texts following E-E-A-T principles (Expertise, Experience, Authority, Trustworthiness).
• Structured content using subheadings, bullet points, and images.
• Added FAQ schema markup to improve search snippets.

Results:

• Average CTR increased from 0.9% to 4.7%.
• Website inquiries tripled.
• Rankings improved by 12-18 positions in three months.

How to Conduct a Content SEO Audit Yourself (Checklist):

1. Check Title tags and H1-H6 headings (they should include keywords).
2. Identify duplicate content and Title tags (Screaming Frog, Copyscape).
3. Check content uniqueness.
4. Optimize internal linking between pages.

Tools:

• Screaming Frog – duplicate content analysis.
• Copyscape, Content Watch – plagiarism check.
• Google Search Console – click-through rate analysis.
• ChatGPT or DeepSeek

Backlink Profile Analysis: If Links Are Dragging Your Site Down

What Do We Check?

• Quality of external backlinks – the authority of sites linking to your resource. Links from trusted sources improve SEO, while spammy links can harm rankings. Analyzed via Ahrefs and Majestic.
• Number of “toxic” backlinks – links from low-quality or harmful websites that can trigger search engine penalties. Checked using Google Search Console, Ahrefs, and SEMrush.
• Internal linking structure – how well pages on the site are connected. Proper internal linking enhances navigation, distributes page authority, and aids indexing.
• Anchor text profile – the variety and naturalness of the text used in backlinks. Over-optimized anchor text can lead to search engine penalties.

Case Study:

Client: a construction company.

Problem: site rankings dropped, and pages disappeared from search results.

Our audit revealed:

• 200+ backlinks from spammy sites (forums, link directories).
• Excessive use of keyword-stuffed anchor text (which looked unnatural).
• Poor internal linking—important pages lacked internal links.

Solution:

• Disavowed toxic links via Google Disavow Tool.
• Diversified anchor text to make it more natural.
• Implemented a structured internal linking strategy.

Results:

• The site was re-indexed by Google within three weeks.
• Traffic increased by 50% in two months.
• Search rankings improved by 8-10 positions.

UX Audit: If Users Leave Without Engaging

What Do We Check?

• Behavioral factors (time on site, bounce rate) – metrics that show how users interact with the site. Time on site indicates engagement, while the bounce rate measures the percentage of visitors who leave without interacting.
• Navigation and usability – clear website design, menus, and logical page structures that help users find information quickly and easily.
• Page structure and readability – proper arrangement of headings, paragraphs, lists, images, and other elements for comfortable reading.
• Calls to Action (CTAs) – buttons and elements that encourage users to take action (leave an inquiry, subscribe, make a purchase). CTAs should be visible, clear, and persuasive.

Case Study:

Client: a corporate website for an online school.

Problem: high traffic but few inquiries.

Our UX audit revealed:

• The main CTA button was hard to notice (it blended into the background).
• Registration forms were too complex (too many required fields).
• The menu was overloaded (too many sections, hard to navigate).
• 65% of visitors left the site within the first 15 seconds.

Solution:

• Redesigned the CTA: made the button more visible and the text more compelling.
• Simplified registration forms (kept only name, phone, and email).
• Optimized the menu: made it shorter and more intuitive.

Results:

• Conversion rate increased by 78%.
• Bounce rate decreased from 65% to 42%.
• Course sales increased by 2.5 times.

SEO audits are not just about recommendations; they help identify and fix website weaknesses.

• Technical audits reveal critical issues in code, indexing, and speed.
• Content audits show why texts may not be effective.
• Backlink analysis helps prevent penalties and build authority.
• UX audits improve user experience and increase conversions.
