For those new to SEO, a technical audit might sound like a task requiring specialized tools and in-depth knowledge. However, many significant technical issues on websites can actually be discovered with a simple Google search.
I've conducted basic audits for two websites: one was an educational site offering tutoring services with around 500 organic search visits per month, and the other was an e-commerce platform selling discounted goods with approximately 11,000 monthly visits. Surprisingly, both sites had prominent technical problems, and one had even been hacked.
These issues are not isolated incidents. Even well-known websites in the marketing space often suffer from various technical vulnerabilities. The key is that you don't need expensive SEO tools to find them.
Many people are eager to create content and build backlinks, overlooking a crucial fact: if a website's technical foundation is flawed, even the best content won't perform optimally.
Imagine you've crafted a high-quality blog post, but due to an incorrect HTTPS configuration, Google crawls the HTTP version. This HTTP version might then be compromised by a hacker who injects spam links. Or, perhaps your product pages are indexed hundreds of times due to URL parameter issues, diluting their authority.
These problems won't cause a website to collapse immediately, but they act like a chronic illness, continuously harming your SEO performance. What's worse is that many people are completely unaware these issues even exist.
For users building websites with WordPress, technical problems are particularly common. Examples include not deleting default pages after installation, excessive indexing of tag pages, and author pages inadvertently revealing internal information.
The first step is to verify that your website has only one canonical version. Enter the following four addresses into your browser one by one:
• http://yourdomain.com • http://www.yourdomain.com • https://yourdomain.com • https://www.yourdomain.com
Ideally, all versions except your chosen canonical one (recommendation: https://yourdomain.com) should automatically redirect to the canonical version.
The first website I audited had a problem at this stage. Its HTTP version did not redirect, and more seriously, 164 of these HTTP pages were indexed by Google. Clicking on them revealed pages filled with random links pointing to Swiss financial websites and Canadian driving schools, clearly indicating a hack.
Enter the following into the Google search bar:
site:yourdomain.com -inurl:https
This operator will display all pages indexed without using HTTPS. If you have enabled an SSL certificate, there should be no results here. If numerous results appear, it signifies that old HTTP pages are still in Google's index, and 301 redirects need to be set up.
Enter the following search operator:
site:yourdomain.co.uk intitle:yourdomain.com
The e-commerce website I audited had this issue. The site actually used a .co.uk domain, but hundreds of pages had .com in their title tags. This inconsistency not only affects brand image but can also reduce click-through rates, as users become confused when the domain in the search results doesn't match the title.
For WordPress sites, you can use these operators:
site:yourdomain.com inurl:tag
site:yourdomain.com inurl:author
site:yourdomain.com inurl:page
site:yourdomain.com inurl:welcome-to-wordpress OR inurl:hello-world
These operators check if tag pages, author pages, pagination pages, and default WordPress installation pages are being indexed, respectively.
E-commerce websites also need to pay special attention to URL parameter issues. For example:
site:yourdomain.com inurl:page
site:yourdomain.com inurl:sort
The e-commerce site I audited had hundreds of duplicate pages indexed due to pagination and sorting parameters, seriously diluting page authority.
Enter the following operators to check for sensitive files being publicly indexed:
site:yourdomain.com filetype:pdf
site:yourdomain.com "lorem ipsum"
The first operator finds all indexed PDF files. In my research, I've encountered instances where companies unintentionally exposed sensitive information like employee payrolls and customer addresses. The second operator checks for pages still using placeholder text, indicating content was published before it was finalized.
Google search operators can uncover many obvious problems, but they have three limitations:
First, Google doesn't frequently re-crawl "unimportant" pages, so search results can be outdated. You might have fixed an issue, but Google's index might still show the old version.
Second, Google cannot directly tell you the number of 301 redirects or 404 errors; you need to click on each page individually to verify.
Third, Google doesn't proactively monitor your website. You have to manually perform these searches regularly, making it easy to miss problems.
This is why professional SEO teams use tools like Ahrefs for systematic audits. These tools can automatically detect over 100 common technical issues, generate detailed reports, and continuously monitor website health.
However, if you're a solo website owner or a small team just starting, using Google for a basic audit is sufficient to identify most critical issues. The key is to develop a habit of regular checks.
Discovering problems is just the first step; establishing a long-term content and SEO operation system is more important.
Many people, after fixing technical issues, face the next challenge: how to continuously produce high-quality SEO content? The traditional approach involves hiring writers, creating content calendars, and publishing piece by piece – a process that is both time-consuming and difficult to scale.
If you aim to quickly build a content advantage after securing your technical foundation, SEOInfra offers a different approach. It doesn't just help you write blog posts; it empowers you to efficiently transform your existing high-quality content sources (like YouTube videos, podcasts, or industry discussions) into original blog posts that search engines can index, automating SEO structuring and publishing.
For cross-border e-commerce or SaaS websites, this means you can expand content coverage continuously while maintaining technical health, without significantly increasing your team size.
In addition to the main issues mentioned above, some finer details are worth noting.
Blank or Duplicate Meta Descriptions. In Google search results, if you see many pages with descriptions like "..." or identical template text, it indicates that meta descriptions haven't been set up correctly. While meta descriptions don't directly affect rankings, they do impact click-through rates.
Truncated Title Tags. If a title is cut off by an ellipsis in the search results, it means the title is too long. Google typically displays 50-60 characters, and anything beyond that is hidden.
Facetted Navigation Indexing Issues. The filtering functions commonly used by e-commerce websites (sorting by color, size, price, etc.) generate numerous URL variations. If these pages are all indexed, they can severely dilute the authority of the main product pages. You should use noindex tags or robots.txt to prevent these pages from being crawled.
If your website's content is updated frequently, it's recommended to perform a basic audit monthly. If your website is relatively stable, once per quarter is sufficient. The key is to conduct an audit both before and after any major redesign or migration.
Immediately remove malicious code, change all administrator passwords, update all plugins and themes to their latest versions, and then submit a re-crawl request in Google Search Console. Simultaneously, check server logs to identify the entry point of the hack and patch the vulnerability.
If these tag pages have thin content, simply listing a few articles, it's advisable to add a noindex tag. However, if your tag pages have rich descriptions, unique content, and are optimized for specific keywords, keeping them indexed can be valuable.
A small number of 404 pages are normal; Google understands that some content may be removed. However, if a large number of important pages return 404 errors, or if these 404 pages have many internal links pointing to them, you need to set up 301 redirects or fix those links.
Google search operators are free and fast, suitable for discovering obvious issues. Professional tools offer more comprehensive data, automated monitoring, and detailed reports, making them ideal for teams that need to manage SEO systematically. They can be used in conjunction: start with Google for preliminary diagnosis, then use tools for in-depth analysis.
