Technical SEO covers the updates you make directly to your website. These updates impact how well your pages are crawled and indexed. They also influence where your pages ultimately rank in search. Technical SEO audit ensures your content is discoverable by Google and other AI systems. Even as search evolves, AI still depends on fast, structured sites. It covers page titles, title tags, sitemaps, redirects, and metadata. It does not include analytics, keyword research, or social media strategies.
In the Search Experience Optimization framework, technical SEO always comes first. Every other SEO project should follow once your site is solid. For enterprise sites, keeping on top of issues can feel overwhelming. The good news is that most common problems are straightforward to fix. Here are the most overlooked technical SEO issues you may find in your audit.
1. No HTTPS Security
An unsecured site is an instant red flag for visitors. Google Chrome will flag your domain with a “not secure” warning. In the worst cases, users see a red background and leave immediately. That kind of first impression can seriously damage your traffic and trust.
How to Fix It:
- Purchase a certified SSL certificate from a Certificate Authority.
- Install the certificate, and your site becomes instantly secure.
2. Multiple Homepage Versions
Google may be indexing multiple URL versions of your site simultaneously. This dilutes your search visibility and confuses Google’s indexing algorithm. Multiple live versions of the same page can seriously hurt rankings.
How to Fix It:
- Check that all URL variations lead to the same standard URL. To be thorough, test every variation.
- Use “site:yoursitename.com” to spot pages indexed from multiple URL versions.
- Set up 301 redirects as soon as possible, or contact your developer
- You can also set your canonical domain in Google Search Console.
3. Duplicate Content
Duplicate content is a widespread problem for brands using dynamic websites, content management systems, or running global SEO campaigns. It can confuse search engine crawlers and prevent the right content from reaching your target audience. Unlike thin content issues, duplicate content can creep in from several different directions.
How to Fix It:
- Resolve ecommerce URL duplication with proper rel=canonical tags.
- Fix printer page issues by configuring as outlined above.
- Address multilingual duplication by correctly implementing hreflang tags.
Google’s support page also offers additional guidance on limiting duplicate content, including using 301 redirects, top-level domains, and reducing repetitive boilerplate content across your site.
4. Missing Alt Tags
Missing alt tags and broken images are missed SEO opportunities. Image alt tags help search engines index pages by telling bots what an image is about.
Therefore, image content can enhance your website’s experience and boost its SEO value.
How to Fix It:
The majority of SEO site audits identify broken images or missing alt tags. The best way to ensure your alt text and image content are up to date is to conduct regular site audits.
5. Broken links
Strong internal and external links signal quality to both users and search crawlers. But over time, content changes and once-reliable links break. Broken links disrupt the user’s journey and reflect poorly on your content quality, which can directly affect your page rankings.
How to Fix It:
- Confirm internal links whenever a page is removed, changed, or redirected.
- Monitor external links regularly as their value can shift over time without warning.
- Run regular site audits, it is the most scalable and efficient way to catch broken links before they cause damage.
- Use an internal link analysis to identify exactly where broken links live so they can be replaced with the correct or updated page.
- Use the backlinks feature to track all broken external links. From there, reach out to the linking sites and provide them with the correct updated link or page.
6. Poor Meta Description Optimization
Meta descriptions are 160-character snippets that describe a website’s content. A well-written meta description can also pique users’ interest and encourage that crucial click. This is a very simple SEO feature that countless sites still ignore. Meta descriptions, like your page content, should contain relevant keywords that accurately represent what users will find on your page.
How to Fix It:
- Determine the value of each page and prioritize fixes accordingly.
- For existing meta descriptions, evaluate pages based on performance and organizational value.
- Regularly update the meta descriptions of any edited page.
- Always ensure every meta description is unique to its page because duplicate meta descriptions are just as problematic as missing ones.
7. Mobile-First Indexing
Google has confirmed that mobile-first indexing now represents more than half of all websites appearing in search results. This means your mobile site is no longer secondary, it is the version Google primarily uses to crawl, index, and rank your content. If you use responsive web design, you are likely already in good shape. However, if you run a separate “.m” mobile site, getting the implementation right is critical to protecting your search visibility.
How to Fix It:
- Update all metadata on your mobile site, ensuring meta descriptions are identical across both mobile and desktop versions.
