What is technical SEO audit

Technical SEO refers to any work that you do to improve the performance of your website. It includes crawling and indexing your website, content strategy, link-building strategies, etc., that work in tandem to help your pages rank high in the SERPs. The different aspects of technical SEO include on-page SEO and off-page SEO.
On-Page SEO: - On-page SEO refers to the content that tells search engines and users what the page is about, including image alt text, keyword usage, meta descriptions, H1 tags, URL naming and internal linking. You have the most control over on-page SEO because, well, everything is on your site.
Off-Page SEO: - Off-page SEO tells the search engine how popular and valuable your page is, from backlinks or links from other sites to your own. Backlink quantity and quality boost page rank. To get more backlinks from relevant websites, you can focus on social media marketing, influencer marketing, affiliate marketing, etc.
Technical SEO plays an essential part in organic traffic. You may have written great content, but very few people will see it unless a search engine can crawl it. With technical SEO best practices, you can not only crawl your website but also work on other factors like indexability, using an SSL certificate, enabling accelerated mobile pages, adding structured data to your website, etc. Some of the common points to focus on, whether it is for on-page SEO audit or off-page SEO audit, are mentioned below as follows:

1. Crawling and indexing – One of the first things to work on when performing a technical SEO audit is to run a crawl report for your website. Crawling your website on an SEO tool provides insights into the various KPIs that need to be worked on to improve the website's performance. Crawling your website, you will see a clear report of duplicate content, low page speed, missing H1/H2 tags, etc. Once you have the information on various metrics, you can work on optimizing them.
You can start by checking the robots.txt file. It would help you know which parts of your website should be crawled and what are to be left out. The robots.txt file is publically available and can be found by adding ‘/robots.txt’ to the end of any root domain. You just have to enter the URL on the site to check if it is crawlable or if there are any errors or warnings in the robots.txt file. You can even consider crawling your webpage on the screaming frog tool.
Once the crawling process is done, you need to understand whether pages on the site are being indexed or not. Indexing allows search engines to see all of your pages and redirect users to the relevant page. It helps to increase traffic on the webpage. Indexing allows the search engine to identify new content quickly. You can use the Google URL inspection tool and see whether the pages are indexed or not. Performing SEO site audit, you get to know the various pages that are indexed and the reasons why others are not. Using the Google Analytics API is a good way of identifying essential pages and check for their indexing. Some points to focus on when working on indexing are:
• Check whether the HTTP or HTTPS version is being used
• Check whether duplicate pages are indexed or they should be canonicalized
Once content on the webpage has been indexed, it can be served up on search engine results pages (SERPs) for relevant search queries. Website audits are an essential to evaluate how easily a search engine can discover, crawl, and index everything from individual elements of a webpage to an entire domain.

2. Duplicate content - Search engines see each URL variation as a separate page. They’ll count duplicate content as any instance where two URLs point to the same piece of content. So, to improve the ranking on the SERPs, you should consider writing unique content. It would help you increase traffic to your website, improve user experience, have a lasting impression, increase sales, build customer loyalty, etc.
With a technical SEO audit, you get to know the critical aspects to focus on and update the content. With a proper website audit, you get to know what sections on the webpage, subsections, etc. are to be focused on. The most important aspect of why duplicate content is most important for a technical SEO agency is that even Google penalizes websites that have the same content. For instance, frequent duplicate title tags will result in the devaluation of all your title tags. You can consider using tools such as Siteliner, Copyscape, Screaming frog, etc., to search for duplicate content, check H1s, check for the same meta description, etc., when performing a technical SEO audit.

Content

3. Optimize 404 pages – A 404 page is shown to the users when the URL they visited does not exist on your website. In simple words, a 404 error is an HTTP status code which means that the server couldn’t load the page that the user was trying to land on. The reason for the page not being loaded could be the page was deleted, the URL was changed, or they mistyped the URL in their browsers. When performing a technical SEO audit, you can use a tool like Google Search Console to keep an eye on the number of ‘Not Found’ error codes and broken links your site generates. You can also use Google Analytics to see how many visitors are landing on 404 pages.
For a technical SEO agency, optimizing the 404 error is essential to increase users' trust, improve brand awareness, etc. An optimized 404 page should:
• Have the same structure and navigation menus as your website
• Tell the visitors in a friendly language that the webpage they are searching for is no longer available
• Give them alternative related pages
• Make it easy for them to return to the previous page, home page, etc.

4. Canonical URLs – These are a simple way to inform the search engine which version of a page is considered when indexing your website. It is similar to the preferred domain, where a single page is accessible through various URLs. These are also used to highlight the duplicate content on your website. A canonical tag tells the search engine that the content on the specific page is authentic, thus reducing the chance of plagiarism and being penalized by the search engine. Suppose you have identical pages for mobile and desktop versions and do not tell the search engine which URL is canonical. In that case, the search crawlers choose the canonical version themselves and then crawl the same to rank on the search result pages. Thus, in your SEO site audit process, you should consider specifying a canonical URL for all pages of your website.
The technical SEO best practices include using canonical tags in multiple URLs (accelerated mobile pages), location-specific URLs, etc. Some scenarios where webmasters can use canonicalization to guide search engines and improve the chances of being ranked higher in the SERPs are discussed below:
• Ecommerce sites using multiple variations - Ecommerce sites often set separate URLs for the different products and change them whenever there is a price change, discount offered, etc. Since search engines work on artificial intelligence, so there are chances that they may redirect users to irrelevant pages. So, in your SEO site audit process, you need to add separate canonical URLs to redirect the target audience to the page they are looking for and increase the e-commerce conversion rate.

• Blog content - Blog content helps digital marketers boost brand awareness and allows relevant users to know more about the marketing trends. It provides advertisers with the opportunity to write great content and increase traffic on the webpage. With the SEO audit tool, you need to figure out that the content is not duplicated and use canonical tags so that webmasters can easily share high-quality content without any worry about SEO performance.
• A/B testing webpages – Most digital marketing agencies use a/b testing in their marketing strategy to assess what works best to increase their business ROI. When performing a website audit, you need to add canonical tags to the version that yields better results. It would help to crawl the relevant pages and display the same.

5. Mobile – friendly website – As a technical SEO agency, you should ensure that your website is mobile-friendly to improve your SEO ranking, increase traffic on the webpage, increase sales, etc. Also, with the launch of mobile-first indexing by Google, you cannot miss the opportunity to make your website mobile-friendly as it provides a slight advantage to improve ranking on the search engine. As a technical SEO agency, you should consider optimizing images, adjusting font size, using accelerated mobile pages, embedding videos for mobile devices, etc. The target audience can take the intended action on the web page 24/7.
Having a mobile-friendly website helps to lower the bounce rate. 40% of people abandon a website that takes more than 3 seconds to load. When performing a technical SEO audit, you need to focus on the fact that the website takes less time to load so that users do not have to wait much to see what they are looking for. Having a better site speed improves the user experience. It increases the chances of the user becoming a customer as the users find website navigation easy. To check your website speed, you can use Google’s Page Speed Insights tool.

6. Optimize your XML sitemap – An XML sitemap is an XML file that lists all pages or posts available on your website. It includes their title, published date and last updated date. Search engines can use the XML sitemap as a guide when crawling the website. When performing a website audit, you need to focus on keeping your sitemap updated so that the target audience gets to have the most relevant content for the product or services they are looking for. When working on technical SEO, you need to ensure that the XML sitemap meets the below-mentioned points:
• Make sure your sitemap is appropriately formatted in an XML document
• Ensure that it follows XML sitemap protocol and avoid sitemap pages or other pages that have duplicate content.
• Make sure that your sitemap is automatically updated when a new page is published or updated.
• Use the Google search console or the Bing webmaster tools to submit your sitemap and check the status.
