12 Common Technical SEO Issues (and How to Solve Them)

This is where technical SEO comes into the picture.

So, when did you last scrutinize your technical SEO status?

Here are the 12 most common and inevitably damaging technical SEO errors you must fix ASAP.

What is technical SEO?

Technical SEO refers to the practice of optimizing a site and server so the search engine can crawl and index the site seamlessly. It includes optimizing the site architecture and other technical factors for better online visibility.

Unlike page optimization, technical SEO generally refers to site-wide changes. Technical

SEO comprehensively covers JavaScript indexing, SEO tags implementation, Sitemaps, Meta tags, links, keywords, etc.

Here you need to fix several site-wide factors to meet the technical requirements of search engines, which will help the site to index and render appropriately and rank in search engine results pages (SERPs).

12 common technical SEO issues

1. An issue with site indexation

So, you switched to Google to check your site rankings but failed to find your site listing. You even tried to search with your brand name, but to no avail.

What’s causing this? There might be an issue with your site indexation.

So, unless your site is indexed appropriately, it’s not going to be recognized and picked up by search engines.

To check if your site has an indexation issue, you can Google “site:yoursitename.com”

The results will show you all the indexed pages of your site.

Now, you can analyze and fix some of the most common indexation issues:

  • If you see no listings from your domain, you need to manually initiate indexing. Here's what you need to check.
  • If you can’t find some site pages in the list of indexed pages, you need to check these pages. Ensure they abide by Google’s Webmaster Guidelines, or you can encounter optimization issues.
  • If some important site pages aren’t showing in listings, check the Robots.txt file. You might have blocked these pages in the Robots.txt file. In some cases, you might have forgotten to remove the NOINDEX tags from these pages.
  • If you see some more pages than you expected, these can be owing to two cases; either you have some old site pages still ranking, or your site has fallen victim to hacking spam. 
  • If some pages from the older site version are ranking, you need to redirect them to new pages. 
  • In hacking spam, create a list of spam pages and use Google’s Disavow Tool to remove them. 

2. Robots.txt file isn’t compiled appropriately

You probably know that you cannot miss out on adding the Robots.txt file to your site. But, something else that can impact your technical SEO is an incorrect Robots.txt file.

The mistakes in your Robots.txt file are generally made by a developer while rebuilding your site.

How can you check if your Robots.txt file isn’t configured correctly?

Type “yoursitename.com/robots.txt” in the Google search bar. If the result shows “User-agent:*Disallow:/,” you need to rectify the Robots.txt file.

This error prevents all search engine robots from crawling your site pages.

Here’s how the error looks: 

How can you fix the poorly configured Robots.txt file?

  • The “Disallow:/” error is something that your developer needs to fix as soon as possible. They might have an explanation for this configuration or might have carelessly missed it out.

If you have an ecommerce website, you’re likely to have a complex Robots.txt file. Here you would need to scrutinize the Robots.txt file line by line along with the developer.

3. The NOINDEX tag isn’t removed

The NOINDEX tag tells Google not to index your webpage. The tag will remove a page from Google’s index altogether.

A developer adds the NOINDEX tag while the site is in the production phase, and must remove the tag while making the site live.

You can do a manual check to see if this has been done by checking the page’s source code for “NOINDEX” tags. However, a better way is to use the Screaming Frog tool to scan all site pages at once. If you find these tags, you can change them to “INDEX” tags or remove the NOINDEX tag.

Things to implement:

  • If your site undergoes constant modification, developers need to be extra careful about removing NOINDEX tags. 
  • You must ensure you check your site every week during the constant upgrades. 

4. Your site doesn’t have an XML sitemap

Search engine crawlers can index your site if you have a well-defined internal link structure.

However, the XML sitemap guides the crawlers to comprehend your site structure, , helping them choose the most efficient way to index your site.

It also ensures that all your optimized site pages are indexed properly. This is especially important for complex sites with hundreds to thousands of pages.

You may find one of these XML sitemap issues:

  • The site lacks a sitemap
  • The location of the sitemap isn’t mentioned in Robots.txt
  • You have not updated the sitemap after upgrading the site architecture
  • You have multiple sitemap copies on your site
  • You have most likely forgotten to remove the old sitemap copy while adding the new one

How can you resolve XML sitemap issues?

Check for all the above issues and resolve them with assistance from a developer.

If your site lacks an XML sitemap, prepare one with the help of a developer. You can also use Yoast Plugin or AIO SEO plugin for WordPress sites to generate sitemaps.

Also, examine the indexation of the pages you add to your XML sitemap. You can use Google Search Console for the same.

5. Missing canonical tag

The rel=canonical tag is crucial when you have similar content sections on more than one page.

This is more common for ecommerce sites. When a product falls under multiple categories, Google considers these category pages as duplicates.

The same issue strikes when a blog page falls under multiple categories.

Therefore, the use of the rel=canonical tag helps you point at the original page. Now Google crawlers can prioritize the original page and index it.

How can you check and fix the rel=canonical tag?

  • You must spot-check the important pages of your site for the rel=canonical tag. 
  • A site audit tool will also help you scan and reveal duplicate page errors. You can ask the developer to add the canonical tag on these pages. 

6. Improper 301 and 302 redirection

Redirection is a crucial way to manage the dead pages and pass the link equity to important pages.

Redirects facilitate a hassle-free site migration and site upgrade process, and if you fail to use these redirects appropriately, you lose your traffic, rankings and site authority.

That said, one must know how to employ 301 and 302 redirects.

  • 301 is a permanent redirect and passes the highest link equity
  • 302 is a temporary redirect that passes a comparatively lower share of link equity

Here are some common misconceptions that you must be wary of:

  • You can easily redirect all the 404 errors on your site: No, you cannot go overboard with redirects.
  • You must redirect all URLs to the homepage to increase its authorityNo, this can do more harm than good.
  • Create more redirects to gain more link equity: No, this will ruin your site authority; you must keep your redirect list to a minimum. 
  • The rel=canonical tag will waste the link equity instead of redirecting to the original page: No, one can only do it in some cases. 

How can redirection errors be fixed?

  • Check all your site URLs and the 404errors. Redirect pages that either gain traffic or receives a link. 
  • Ask your SEO partner to check the 301 and 302 redirects. If there’s a 302 redirect used for permanent redirection, change it to 301 redirects.
  • Check the redirects that you implemented in the previous migration or re-launching process. 
  • Monitor the redirection report monthly or whenever you update your site. 

7. Broken links affecting site ranking

When you migrate a site or re-launch it with some new pages and URL, many links break. Old pages may cease to exist, and the backlinks to these pages now read 404 errors. This causes you to lose your link equity.

Moreover, many internal links still point to old pages, affecting the user experience significantly. It may also lead to the formation of some orphan pages.

How can you identify this issue?

Use tools like Google Search Console and SEMRush to find your broken backlinks report. 

Google Search Console enables you to check the list of 404 errors. Here the broken backlink errors top the list.

How can you resolve broken links errors?

Once you have a list of these 404 pages, 301 redirect them to the relevant new pages.

You can also contact some site owners to change the backlinks to your new page URL.

Use Google Alert and Mention tools to check which sites have mentioned your brand. Here you can ask them to give you backlinks to your new relevant pages.

Also, monitor your internal links each time there are significant content changes in the site. 

8. HTTP or “Not Secure” site

HTTPS site security is no longer an option as it significantly affects your SEO and conversion rate optimization (CRO).

What’s worse is that when you enter an HTTP URL in Chrome:

  • It shows the site URL in a grey background if it isn’t transactional. 
  • Alternatively, it shows a red highlighted “Not Secure” warning if the site has a transactional nature.

The “Not Secure” warning is most likely to off-put visitors, and they will bounce back.

On the other hand, the sites with HTTPS security are highlighted as “Secure” in Chrome.

You must consider buying the SSL security certificate for your site to make it HTTPS. You would then have to upload the certificate and migrate the site from HTTP to HTTPS.

Ensure that you do the migration work under the supervision of an SEO Expert. They will ensure you don’t lose any current SEO value.

9. Slow page load speed

A slow-loading website isn’t likely to impress Google nor the visitors. In fact, it messes with your site’s SEO power and conversion rate optimization (CRO).

  • Dotcom-Monitor reports that the bounce rate increases by 75% if a site takes more than 3 seconds to load. 
  • Google recommends that the page load speed must not exceed 3 seconds for both desktop and mobile platforms. 
  • And it expects ecommerce sites to load even faster. As Maile Ohye says in the Google Webmaster video: “2 seconds is the threshold for ecommerce website acceptability. At Google, we aim for under a half-second.”

Moreover, Google recently introduced the Page Experience Update in 2021. The update made Core Web Vitals one of the important ranking factors.

This update has made page speed all the more crucial for better SEO performance.

You can assess your website loading speed using the Google PageSpeed Insight tool. Ensure that you check for both the desktop and mobile versions. 

The tool displays several errors and recommendations that you can follow for optimization.

How can you resolve page speed issues for a slow site?

Some of the effective ways to optimize a site’s loading speed include:

  • Employ content delivery network (CDN)
  • Minify HTML, CSS, and JavaScript files
  • Use asynchronous loading;
  • Gzip your WordPress files
  • Defer loading JavaScript files

You can employ these optimization factors with the help of a developer.

10. Unsynchronized internal linking structure

A majority of webmasters don’t prioritize internal linking, and an unsynchronized internal linking structure both impacts your site’s crawlability.

If you have a multiple-page, complex site, you must make sure you follow scalable internal linking. A complex site without a defined site structure is likely to face indexation errors. And it might also produce orphan pages.

Another common issue is over-optimized anchor texts. Over-optimization can impact the quality of your on-page content.

The right internal linking structure helps share the link equity among the important pages. And it pushes your position higher in the SERPs.

How can you check and fix the internal linking structure?

  • Conduct a technical audit of the site to check the internal link count. Check if the most crucial pages on your site are receiving adequate links. Also, check if there are any orphan pages. 
  • Take a manual look at all the in-content links across the site. See if there are any broken links, over-optimized anchor texts, or linking opportunities. Fix these errors. 
  • Ensure that your content creators follow a smart linking pattern whenever they post new content. 

11. Meta Tags aren’t optimized

Meta Tags have a considerable impact on your site’s SEO. They form your page’s preview snippet in the SERP listings, and your Meta Title or SEO Title is a valuable ranking factor.

But often businesses fail to optimize their Meta Tags and miss out on the meta description.

Your meta description has little to no impact on your SEO but is crucial for your page CTR.

As per best practices, you must add Meta Tags to all your site pages that are indexed.

The length of the Meta Title must not exceed 55 characters. And you must add the primary page keyword to the Meta Title.

The length of the meta description must not exceed 160 characters. Moreover, it must include the important page keywords to boost relevancy.

Check and resolve

You must check your Meta Tags status during the site’s SEO audit.

Look for the pages missing Meta Title or Meta Descriptions. Add the missing Meta Tags to all the important site pages.

Ensure that you don’t miss out on Meta Tags every time you add a new page on the site.

12. Site images aren’t optimized and lack alt tags

Images are essential to construct the right user experience for your site. But if you fail to optimize your images, they slow down your site.

Moreover, another common issue is the missing Alt tags. Alt tags are image description tags that define an image’s content for the crawlers.

The Alt tags must also include relevant page keywords to get some SEO advantage. This practice helps the images rank for image search in Google.

What’s the best way to fix these issues?

  • When you run a speed test on your site, you get a list of image size errors. If you haven’t compressed your site images, you can use several tools to do the same. WPSmushit is one such tool that helps you with image compression for WordPress sites. 
  • A site audit report can help you reveal the broken images and missing Alt tags. You can replace the broken images with optimized images. Also ensure, to add Alt tags to all the images on your site.
