Just as weeding a garden eliminates factors that hinder a plant\u2019s growth, technical SEO helps your site get it&#8217;s full potential by creating an environment where your SEO efforts can thrive.

Improving<\/b> <b>linking structure<\/b><\/p>\n<p>A well-structured site is essential for both users and web crawlers. For users, an intuitive <a href=\"https:\/\/www.similarweb.com\/blog\/marketing\/seo\/site-architecture-for-seo\/\">site structure<\/a> makes it easy to find information. It also facilitates efficient indexing for web crawlers. Pages that crawlers can&#8217;t find won&#8217;t be included in search indexes, rendering them invisible in the search results.<\/p>\n<p><b>2. Increasing user experience<\/b><\/p>\n<p>User experience is critical from both user and search engine perspectives. According to <a href=\"https:\/\/www.webfx.com\/blog\/seo\/site-speed-statistics\/\">webfx.com<\/a>:<\/p>\n<ul>\n<li aria-level=\"1\"><b>83% of users <\/b>expect websites to load in three seconds or less<\/li>\n<li aria-level=\"1\"><b>40% will abandon a site<\/b> if it takes longer than three seconds to load<\/li>\n<li aria-level=\"1\">Pages loading in <b>1-2 seconds have an extremely low average bounce rate of 9%<\/b>, while those taking 5 seconds have a 38% bounce rate<\/li>\n<\/ul>\n<p>From a search engine perspective, in 2021, <a href=\"https:\/\/www.similarweb.com\/blog\/marketing\/seo\/core-web-vitals\/\">Google\u2019s Core Web Vitals<\/a> became a part of its ranking algorithm, measuring:<\/p>\n<ul>\n<li aria-level=\"1\">Page load speed<\/li>\n<li aria-level=\"1\">Responsiveness<\/li>\n<li aria-level=\"1\">Stability<\/li>\n<\/ul>\n<p><b>3.

In our current digital landscape, with competitors lurking around every corner, having a bad user experience is likely to result in diminishing users and lost revenue.<\/p>\n<p>Furthermore, since Google is always looking for ways to improve its user experience, reducing errors makes simple sense from a business perspective. By reducing errors, you are aligning your content with Google\u2019s business goals, and the more you do that, the more likely your content will rank in search results. User experience is evident in many of its <a href=\"https:\/\/www.similarweb.com\/blog\/marketing\/seo\/google-algorithm-updates\/\">updates<\/a>, including:<\/p>\n<ul>\n<li aria-level=\"1\">The helpful content update<\/li>\n<li aria-level=\"1\">Numerous spam updates<\/li>\n<li aria-level=\"1\">Core Web Vitals<\/li>\n<\/ul>\n<h2>Technical SEO best practices<\/h2>\n<p>As technical SEO strategy is a broad topic, let\u2019s break it down into small steps. Here are eight technical optimization best practices:<\/p>\n<h3>1. Make sure your site is crawlable<\/h3>\n<p>In order for your content to appear in search results, you must ensure that search engines can find it. Search engines do this by systematically crawling the web by following hyperlinks in order to discover new or updated content. If your site is not crawlable, it is not accessible, and an inaccessible site will not be indexed.<\/p>\n<p>The next step after crawling is for the search engine to render your content. This means it takes the page built on HTML, CSS, and JavaScript and turns it into a visual representation of that page. The search engine looks at things like JavaScript to see what the final version of the page looks like. This rendering process allows the search engine to evaluate the content and structure of the page accurately.<\/p>\n<p>The best way to improve your site\u2019s crawlability is to ensure you have completed these 8 steps:<\/p>\n<ul>\n<li aria-level=\"1\"><b>Optimize robots.txt files: <\/b>Ensure that your website&#8217;s <a href=\"https:\/\/www.similarweb.com\/blog\/marketing\/seo\/robots-txt\/\">robots.txt file<\/a> is properly configured to allow search engine bots to crawl the necessary pages while blocking access to sensitive or unnecessary content.<\/li>\n<li aria-level=\"1\"><b>Implement an XML sitemap: <\/b>Create and submit an <a href=\"https:\/\/www.similarweb.com\/blog\/marketing\/seo\/sitemaps\/\">XML sitemap<\/a> to search engines, and ensure that your CMS updates it automatically.<\/li>\n<li aria-level=\"1\"><b>Minimize redirects:<\/b> Reduce the number of redirects on your website, as excessive redirects can slow down the crawling process.<\/li>\n<li aria-level=\"1\"><b>Improve page speed: <\/b>Ensure that your website&#8217;s pages load quickly, as slow-loading pages may be deprioritized or even excluded from the crawling process.<\/li>\n<li aria-level=\"1\"><b>Eliminate broken links: <\/b>Regularly <a href=\"https:\/\/www.similarweb.com\/blog\/marketing\/seo\/site-audit-guide\/\">audit your website<\/a> for broken internal and external links, and fix any issues.<\/li>\n<li aria-level=\"1\"><b>Leverage internal linking: <\/b><a href=\"https:\/\/www.similarweb.com\/blog\/marketing\/seo\/internal-links\/\">Well-structured internal links<\/a> help search engine bots discover and navigate your website&#8217;s content more efficiently.<\/li>\n<li aria-level=\"1\"><b>Monitor crawl errors: <\/b>Regularly review your website&#8217;s crawl error reports and address any issues that could be preventing search engine bots from effectively crawling your site.<\/li>\n<\/ul>\n<p>By following these best practices, you can help ensure that search engines are able to easily crawl and index your site, making your content more visible in search results.<\/p>\n<h4>Auditing your site\u2019s crawlability with Similarweb<\/h4>\n<p>The easiest way to audit your site\u2019s crawlability is to use the <b>Similarweb Discoverability report<\/b> in the <a href=\"https:\/\/www.similarweb.com\/corp\/search\/site-audit\/\">Site Audit tool<\/a>.

Make sure your site is indexable<\/h3>\n<p>In the previous step, you ensured that search engines can find your content. But finding the content isn\u2019t enough. For your content to show up and rank in search results, it needs to be indexed. If your pages are not indexed properly, they will not appear in Google\u2019s search results. When you type a query into your favorite search engine, you are not searching the web, you are actually looking through the search engine\u2019s index of the web.<\/p>\n<p>To index content, the search engine needs to process and analyze the content.

Make sure your site has SSL<\/h3>\n<p>SSL (Secure Sockets Layer) creates an encrypted connection between a web server and a browser when visiting a website. This encryption:<\/p>\n<ul>\n<li aria-level=\"1\">Ensures your site is secure<\/li>\n<li aria-level=\"1\">Protects personal user data from potential hackers<\/li>\n<\/ul>\n<p>Having SSL is crucial if your site collects any data, including email addresses. This is something easy to do. You can purchase an SSL certificate from your domain provider. In fact, most web hosting services now offer free SSL certificates through services like Let&#8217;s Encrypt.<\/p>\n<p><span style=\"font-weight: 400;\">To check if your site has an SSL certificate, look at its address.

Optimize site speed<\/h3>\n<p>During 2021, <a href=\"https:\/\/www.similarweb.com\/blog\/marketing\/seo\/core-web-vitals\/\">Core Web Vitals<\/a> became a ranking factor. These metrics are part of a group of user experience metrics that Google measures.<\/p>\n<p>The Core Web Vitals consist of three key measurements:<\/p>\n<ul>\n<li aria-level=\"1\"><b>Largest Contentful Paint (LCP)<\/b>: Measures loading performance by timing how long it takes for the largest content element on the page to become visible within the viewport.<\/li>\n<li aria-level=\"1\"><b>First Input Delay (FID)<\/b>: Quantifies interactivity by measuring the time from when a user first interacts with your site to when the browser is able to respond to that interaction.<\/li>\n<li aria-level=\"1\"><b>Cumulative Layout Shift (CLS)<\/b>: Evaluates visual stability by measuring the sum total of all unexpected layout shifts that occur during the entire lifespan of the page.<\/li>\n<\/ul>\n<p>Given that Core Web Vitals are now incorporated into Google&#8217;s ranking systems, optimizing your website based on these metrics has become important for improving your SEO performance.<\/p>\n<h4>Auditing your site speed with Similarweb<\/h4>\n<p>You can quickly identify your site&#8217;s speed issues using <b>Similarweb&#8217;s Page Speed report<\/b>.

Ensure your site has one version<\/h3>\n<p>Having multiple versions of your site is a form of duplicate content that you must avoid, as it can negatively impact your site.<\/p>\n<p>This includes:<\/p>\n<ul>\n<li aria-level=\"1\">Diluting link equity<\/li>\n<li aria-level=\"1\">Confusing search engines about which version to index<\/li>\n<li aria-level=\"1\">Wasting crawl budget<\/li>\n<\/ul>\n<p>Multiple site versions happen more often than you would imagine.

You can establish pages as primary by adding the <i>rel=canonical <\/i>tag to the HTML head section of your page. Your canonical tag should look like this:<\/p>\n<p><b>&lt;link rel=\u201dcanonical\u201d href=\u201dhttps:\/\/www.example.com\/preferred-page\/\u201d \/&gt;<\/b><\/p>\n<p><b>Pro tip: <\/b>While canonicalization and redirects are essential for managing existing duplicate content, it&#8217;s even better to prevent multiple versions from occurring in the first place. You can achieve this by setting up proper rules in your server configuration to redirect users:<\/p>\n<ul>\n<li aria-level=\"1\">From HTTP to HTTPS<\/li>\n<li aria-level=\"1\">From non-www to www<\/li>\n<li aria-level=\"1\">To add (or remove) a trailing \/.<\/li>\n<\/ul>\n<p>This will resolve most of your technical duplication issues and prevent them in the future.<\/p>\n<h4>Auditing your site\u2019s canonical tags with Similarweb<\/h4>\n<p>You can audit your canonical tags with the<b> Similarweb Canonicalization report<\/b>.

This will help you find all kinds of duplicate content on your site, including:<\/p>\n<ul>\n<li aria-level=\"1\">Duplicate titles<\/li>\n<li aria-level=\"1\">Duplicate body<\/li>\n<li aria-level=\"1\">Duplicate descriptions<\/li>\n<li aria-level=\"1\">Duplicate pages<\/li>\n<\/ul>\n<h3>7. Oversee response codes<\/h3>\n<p>Looking at response codes will help you identify error pages that need to be corrected. Although there are many response codes, you don\u2019t need to know what all of them mean. The main ones to focus on are response codes that represent errors, including <b>4xx<\/b> and <a href=\"https:\/\/www.similarweb.com\/blog\/marketing\/seo\/5xx-server-error\/\"><b>5xx<\/b> response codes<\/a>.<\/p>\n<p>The most popular response codes are:<\/p>\n<ul>\n<li><b>301 Moved Permanently<\/b><span style=\"font-weight: 400;\">: The requested URL has moved to another address.<\/span><\/li>\n<li><b>302 found: <\/b><span style=\"font-weight: 400;\">\u00a0The requested URL has been moved temporarily to a new location.<\/span><\/li>\n<li><b>400 Bad Request: <\/b>The server could not find the requested page.<\/li>\n<li><b>400 Bad Request<\/b>: The server could not understand the request due to invalid syntax.<\/li>\n<li><b>401 Unauthorized<\/b>: The client must authenticate itself to get the requested response.<\/li>\n<li><b>402 Payment Required<\/b>: Reserved for future use. It is intended for use as a means of digital payment systems.<\/li>\n<li><b>500 Internal Server Error<\/b>: The server has encountered a situation it does not know how to handle.<\/li>\n<li><b>501 Not Implemented<\/b>: The request method is not supported by the server and cannot be handled.<\/li>\n<li><b>502 Bad Gateway<\/b>: The server, while acting as a gateway or proxy, received an invalid response from the upstream server.<\/li>\n<\/ul>\n<h4>Auditing your response codes with Similarweb<\/h4>\n<p>The <b>Similarweb Availability report<\/b> will give you a list of availability issues. This includes two reports that analyze response codes, including:<\/p>\n<ul>\n<li aria-level=\"1\">Broken pages (4xx pages)<\/li>\n<li aria-level=\"1\">5xx errors<\/li>\n<\/ul>\n<p>By uncovering the pages with these response codes, you can quickly fix any issues to ensure everyone can navigate your website properly. This is a report you will want to use frequently to keep your site error-free.<\/p>\n<h3>8. Pro tip: Add schema markup and structured data<\/h3>\n<p>Search engines have sophisticated systems designed to understand content created by people. These systems interpret:<\/p>\n<ul>\n<li aria-level=\"1\">The content on a page<\/li>\n<li aria-level=\"1\">What a page is about<\/li>\n<\/ul>\n<p>This is a heavy lift for search engines as they have to convert non-structured human language and convert it into machine-readable structured data.<\/p>\n<p><a href=\"https:\/\/www.similarweb.com\/blog\/marketing\/seo\/schema-markup\/\">Adding schema markup<\/a> is a way to add a machine-readable, structured data layer to your web content. Implementing this will help search engines understand your page and content and will often lead to rich snippets in the search results.<\/p>\n<h2>Tools to detect technical SEO issues<\/h2>\n<h3>Similarweb<\/h3>\n<p><img decoding=\"async\" class=\"alignnone size-large wp-image-194343\" src=\"https:\/\/www.similarweb.com\/blog\/wp-content\/uploads\/2024\/09\/Similarweb-1024x531.png\" alt=\"Similarweb\" width=\"1024\" height=\"531\" srcset=\"https:\/\/www.similarweb.com\/blog\/wp-content\/uploads\/2024\/09\/Similarweb-1024x531.png 1024w, https:\/\/www.similarweb.com\/blog\/wp-content\/uploads\/2024\/09\/Similarweb-300x156.png 300w, https:\/\/www.similarweb.com\/blog\/wp-content\/uploads\/2024\/09\/Similarweb-768x398.png 768w, https:\/\/www.similarweb.com\/blog\/wp-content\/uploads\/2024\/09\/Similarweb-512x265.png 512w, https:\/\/www.similarweb.com\/blog\/wp-content\/uploads\/2024\/09\/Similarweb.png 1379w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/p>\n<p>With <b>Similarweb&#8217;s Site Audit tool, you are able to <\/b>comprehensively analyze all the key technical SEO aspects of your website \u2013 as well as any competitor website.
