These tools classify the page speed into three categories: fast, moderate and slow.

Assessing website security and HTTPS implementation

It is necessary to have website security, to keep your webpage free from any malfunction, or virus, keep customers’ privacy, and free it from any errors.
  • HTTPS implementation must be implemented for the security of the site. It ensures an encrypted connection between the server and its clients. The hosting web may provide the implementation or ask for an SSL or TLS certificate.

http vs https

Analyzing XML sitemaps and robots.txt file

The XML sitemaps are a kind of route map for the search engines in the form of a file where they can crawl for different pages for indexing. It provides all the URLs for the pages for easy search. The robots.txt file helps in locating in the crawling process the URLs which can be accessed. It is essential to analyze this as it helps in increasing the rank.

Checking for duplicate content and canonicalization issues

Another technical issue that causes a reduction in ranking and indexing is duplicate content and canonicalization of the content and URL. It means that there are various variations of the same page.
  • For example, having both a WWW page and a non-WWW or having both HTTP and HTTPS links for the same page.
These issues should be checked and a single URL should be finalized.

Examining website URL structure and hierarchy

Every website URL must follow a certain structure in the hierarchy to be located easily. The hierarchy of the URL follows section, subsection, topic, and page which easily gives the location of the website and the page. The URL must be structured in a way that is complete and short. Make it relevant and have WWW and HTTPS implementation.

Evaluating the website's structured data and schema markup

The search engine that works on code understands the content of your pages on the website through structured data and schema markup. The schema is the language of search engines by which they understand the content of the page and index them. Having structured data via schema markup helps the engines to store the content and index them.
  • You can use a schema markup validator via Google to test whether the data is structured or not.

Identifying and fixing issues related to site architecture and navigation

The site architecture and navigation are usually the way by which users go through the website to a particular page. The architecture and navigation decide on the use of friendliness of the website. Moreover, the search engines also crawl through this navigation. Keeping it easy and short helps in locating the pages both for users and crawlers.

Analyzing internal and external linking strategies

Another aspect that must be focused on in a technical SEO audit is analyzing internal and external linking. Internal linking directs to a different target page on your website whereas external linking directs to a different website. It is necessary to have these links to have website authenticity, increase visibility, user engagement, etc.

Cannibalization: Identifying and Resolving

Cannibalization is the issue when different pages pop up for the same keyword. The issue reduces your traffic. You can resolve this issue by merging the content, deleting some posts or optimizing the content.
  • Cannibalization, where multiple pages compete for the same keyword, can hinder your SEO efforts by diluting the relevance and authority of each page. Tools like Google Search Console are invaluable for identifying this issue by highlighting instances where different URLs appear for the same keyword.

Analyzing a website's JavaScript and CSS usage

  • The CSS coding helps to make the webpage stylish, and impressive and the JavaScript makes it interactive and functional.
  • Analyzing both helps in making the webpage user-friendly, updated and attractive at the same time.

  • DOM manipulation is the process by which you modify, style and change the content of a webpage in Javascript, HTML and CSS by API.

Reviewing server and hosting configuration

It means that you code the webpage in a way that the host machine on your every network is configured to work as per the needs of the users on their end. Each host has their own name, network interface and internet address. 

Further, monitor the server’s security, performance operations and other aspects. It improves the user interface and increases the site reach.

Conducting a comprehensive backlink analysis

Backlink analysis is the analysis of the quality and the volume of links that are associated with your website from other websites. It helps understand how the links impact your ranking.

  • To conduct the analysis you must go to the Google search console, and select the website. Look for the links option and choose external links. There you will find top linking sites which show you the sites linking back to your webpage.


Assessing the website's international targeting and Hreflang implementation

The hreflang implementation means that you are adding an attribute to HTML linking to have specific geographical targeting and language of the webpage.
  • This tag helps the search engines to recognise the variation of the same page based on language. It helps to reach different target audiences and wide reach.
  • It also helps in having an international target audience and reaching them. You can add the tag by going to the HTML code and adding the hreflang attribute.

Each variation should point to its respective language and regional versions, ensuring search engines understand and display the appropriate content based on user location and language preferences.
