An SEO audit is a health check for your website that finds the issues dragging down your rankings, covering Technical, On-page, Off-page, and Content. This article explains what an SEO audit is, the types, the steps to do one yourself, the free tools, and how to prioritize fixes for results, whether you do it yourself or hire an expert.
Your rankings dropped, but you do not know where the problem is?
This is exactly where an SEO audit helps most, because it is a systematic health check of your site to find what is dragging down your rankings and what to fix first. Many businesses keep pouring budget into SEO while basic problems, like a slow site or pages Google cannot reach, remain unfixed.
At Yangdee Group, we start every client engagement with an SEO audit, because it tells us where to act for the best return. This article explains what an SEO audit is, the types, how to do one yourself, and when to bring in an expert.
What Is an SEO Audit?
An SEO audit is a systematic review of your website to find issues that affect your rankings and visibility in search engines. Think of it like an annual health check for your site, helping you see what is strong, what needs improvement, and what to fix first.
The heart of an SEO audit is not just finding problems, but prioritizing which problems matter most. Most sites have dozens of things that could be improved, but only a few that actually affect rankings.
Doing an audit is therefore the best starting point before planning SEO, because it turns guesswork into decisions based on real data.
What Are the Types of SEO Audit?
An SEO audit is divided into four main types based on what they check: Technical, On-page, Off-page, and Content. Each looks at a different angle of your site. Checking all four gives you a full picture of your site’s health, not just part of it.
Technical Audit
Checks the backend elements that let Google access and store your site, such as speed, crawling, indexing, mobile-friendliness, and schema. It is the first gate you must pass. Read more about this in our article on how On-page, Off-page, and Technical SEO differ.
On-page Audit
Checks the content and structure on each page, such as titles, meta descriptions, headings, keyword placement, and internal links. This connects directly to doing proper keyword research.
Off-page Audit
Checks external factors that determine your credibility, especially your backlink profile, whether you have quality links or risky links that need handling.
Content Audit
Checks the quality and relevance of your content, to find thin, duplicate, or outdated content that should be updated, and to reveal new keyword opportunities.
How to Do an SEO Audit Yourself
At Yangdee Group, we use this order as the foundation for auditing client sites. You can adapt it for yourself.
Crawl Your Website
Start by crawling your site with a tool like Screaming Frog to find technical issues you cannot see with the naked eye, such as broken pages, broken links, and structural problems.
Analyze With SEO Tools
Use a tool like Semrush or Ahrefs to scan your site for overall issues and get an SEO score with a list of things to fix.
Check Indexing and Speed
Check whether important pages are indexed, whether canonicals and robots.txt are set correctly, then use Google PageSpeed Insights to check Core Web Vitals like LCP and CLS.
Audit On-page Elements
Look for titles or meta descriptions that are missing, duplicated, too long, or too short, and whether keywords match the content.
Check Backlinks
Review your link profile for risky or toxic links, and whether your links come from trusted, relevant sites.
Compile and Prioritize Findings
Bring all the issues into one file, sort by type, then prioritize what affects rankings most to fix first. This is the step that turns data into a real action plan.
What Are the Free SEO Audit Tools?
There are several good free SEO audit tools, but the most important is Google Search Console. If you use only one free tool to audit your site, Google Search Console should be the one, because it is data straight from Google, covering crawl issues, indexing, and Core Web Vitals.
Here are a few more free tools worth knowing.
Google Search Console is used to spot technical issues, resubmit URLs for indexing, and see which keywords your site ranks for. Semrush SEO Checker scans your site and gives a score with a to-do list. And Ahrefs Webmaster Tools helps find broken links and slow-loading pages.
For businesses just starting out, we suggest using Google Search Console as your main tool first, because it is free, accurate, and covers most of the important issues.
How Often Should You Do an SEO Audit?
You should do a deep SEO audit at least quarterly, and check some key items more often. Most experts recommend running a technical SEO audit at least every three months, because your site, competitors, and Google’s algorithm change all the time.
What you should check more often than quarterly is Core Web Vitals, indexing issues, and broken links, which should be reviewed monthly, because these affect rankings quickly and can be fixed in time if caught early.
The simple rule we use is to treat an audit as an ongoing process, not a one-time project. Checking regularly keeps your site in good shape and prevents problems from piling up.
Doing It Yourself or Hiring an Expert
Doing an SEO audit yourself is possible if you have time and are willing to learn the tools. A basic check with Google Search Console and PageSpeed Insights helps you see the big problems at no cost.
But a deep audit usually requires experience to interpret the results and prioritize which problems are worth fixing first, because the raw data from tools is large, and not every problem affects rankings equally.
The point to consider hiring an expert is when your site is large, has complex technical issues, or when rankings drop and you cannot find the cause yourself. An experienced team saves time and makes every fix measurable, to help your business grow.
Conclusion
An SEO audit is a health check that finds and prioritizes the issues dragging down your rankings. Three things to remember: check all four areas of Technical, On-page, Off-page, and Content, fix what has the biggest impact first, and do it regularly at least quarterly, not just once.
If you want a deep SEO audit that clearly tells you what to fix first and is measurable, our team is ready to help you check and plan the data-driven way. Explore Yangdee’s full SEO services and start planning your business growth with us.
Frequently Asked Questions
How long does an SEO audit take?
It depends on the size of your site and the depth of the check. A small site may take a few hours to a day, while a large site with hundreds of pages may take several days to a week. A basic check with free tools spots big problems quickly, but deep analysis takes more time.
Can I do an SEO audit myself?
Yes, at a basic level, using Google Search Console and PageSpeed Insights to see indexing and speed issues. But deep interpretation and prioritizing which problems to fix first usually requires experience. Businesses that want fast, accurate results often choose to have an expert help.
How much does an SEO audit cost?
The cost depends on your site size and the scope of the check, from a basic check you can do for free with Google’s tools, to a deep audit by an expert team. For details and a scope that fits your business, we suggest contacting us for an assessment based on the actual work.
Is an SEO audit different from a general site audit?
An SEO audit focuses on the factors that affect rankings and visibility in search engines. A general site audit may be broader, covering things like security or overall user experience. In practice they often overlap, because many factors affect both users and rankings.
What do I do after the audit?
After the audit, sort the issues by impact, then fix what affects rankings most first, such as indexing and speed problems, then move on to on-page and off-page. Tracking results afterward with Google Search Console confirms that the changes actually worked.
