By implementing these technical SEO [technical seo] best practices, you can enhance your website’s search engine visibility, drive more qualified traffic, and ultimately increase revenue potential [1].

Site Structure and Navigation

Optimizing your site’s structure and navigation is crucial for both users and search engines. Here are some key strategies to focus on:

  • XML Sitemaps: Submit an XML sitemap to help search engines discover and crawl all your important pages efficiently [4] [5]. Expand your crawl budget by removing unnecessary resources from the sitemap and using robots.txt to disallow low-priority content [5].
  • Logical Site Architecture: Create an SEO-friendly site architecture by organizing pages in a logical hierarchy, with the homepage linking to category pages, which then link to individual subpages [1]. Avoid orphan pages by adding internal links to them from other relevant pages.

  • Clean URL Structure: Use descriptive and keyword-rich URLs for your pages [6]. Properly handle faceted navigation and URL parameters to avoid creating duplicate content or wasting crawl budget [7].
  • Content Organization: Use a clean website structure with proper use of header tags (H1, H2, H3, etc.) to organize content [6] [9]. Improve content structure with elements like:
    • Table of contents
    • Bullet points
    • Headings/subheadings
    • Summary takeaways [10] [11]

By optimizing your site’s structure, navigation, and content organization, you’ll enhance the user experience while ensuring search engines can efficiently crawl, index, and understand your website’s content.

Crawling, Indexing, and Rendering

Search engines work through three primary functions: crawling, indexing, and ranking [4].


  • Search engines use crawlers (also called spiders or bots) to discover new content by following links [4].
  • Crawling is how search engines discover new pages on a website [1].
  • Key crawling optimization tactics include creating an SEO-friendly site architecture and submitting an XML sitemap to Google Search Console [1].
  • Robots.txt files can be used to control which pages search engines crawl [4].
  • Access restrictions like logins, authentication, or IP whitelisting can prevent search engines from crawling certain pages [2].


  • The search engine index is a massive database of all the content that has been discovered and deemed worthy to serve to searchers [4].
  • Indexing is the process of search engines analyzing and storing web content in their search index [1].
  • To ensure proper indexing, the “noindex” tag should be used carefully to avoid accidentally blocking pages from being indexed [1].
  • Meta tags and directives can be used to control how pages are indexed (e.g. noindex, nofollow) [4].


  • Just because a page is crawled doesn’t mean it will be indexed – the search engine analyzes the content and decides whether to include it in the index [4].
  • Rendering is the process where search engines run your website’s code to understand its layout, content, links, and other factors that determine its value [5].
  • Google Search processes JavaScript-powered web apps in 3 main phases: crawling, rendering, and indexing [12].
  • Googlebot queues all pages for rendering, unless a robots meta tag or header tells Google not to index the page. It then executes the JavaScript and parses the rendered HTML to index the page [12].

To ensure proper crawling, indexing, and rendering:

  • Submit an XML sitemap to Google Search Console to help search engines discover and index all the important pages on your site [1].
  • Ensure pages are indexed properly by using the ‘site:’ operator in Google to check how many pages from your site are indexed, and use the ‘noindex’ tag carefully to prevent unintended pages from being indexed [1].
  • Check that your pages are being indexed using Google Search Console. Focus on fixing any pages with errors or warnings [5].
  • Use the URL Inspection Tool in Google Search Console to request indexing for any unlisted pages [5].
  • Ensure proper rendering by checking the HTML that Google has crawled using the URL Inspection Tool [5].

Content Optimization

Content optimization is a crucial aspect of technical SEO that involves optimizing your website’s content to improve its visibility and ranking in search engine results pages (SERPs). Here are some key strategies to optimize your content:

  • Keyword Research and Integration: Conduct thorough keyword research to identify relevant keywords with high search volume and low competition. Strategically integrate these keywords into your content’s title tags, meta descriptions, headings, body text, and image alt text without over-optimization or keyword stuffing [10] [14].
  • Search Intent Alignment: Ensure your content aligns with the searcher’s intent by understanding the preferred content type, format, and angle for your target keywords. This could include informational, navigational, commercial, or transactional intent [14].
  • Comprehensive Coverage: Provide in-depth and comprehensive coverage of your topic by addressing all relevant subtopics and questions that searchers might have. This can help you win featured snippets and improve user engagement [14].
  • Readability and Engagement: Enhance the reader experience by using clear and concise language, varying sentence lengths, and formatting your content with headings, bullet points, and visuals like images and videos [9] [10] [14]. Break up text with short paragraphs and maintain a consistent tone of voice.
  • Unique Value and Shareability: Create content that offers unique insights, data-driven analysis, or a fresh perspective on the topic. This can make your content more shareable and help you build high-quality backlinks [9] [14].
  • Structured Data and Schema Markup: Implement structured data and schema markup to provide additional context about your content and make it eligible for rich snippets in SERPs [6] [7] [14].
  • Optimization for Conversions: For commercial content, incorporate persuasive elements like social proof, case studies, and clear calls-to-action (CTAs) to drive conversions and align with the user’s stage in the marketing funnel [9] [10] [14].
  • Continuous Improvement: Regularly update and improve your content by addressing any gaps, incorporating new information, and responding to user feedback. Avoid over-optimization pitfalls like keyword stuffing, artificially inflating content length, or using overly sensational headlines [10] [14].

By following these content optimization strategies, you can enhance your website’s relevance, authority, and user experience, ultimately improving its visibility and ranking in search engine results.

Page Speed Optimization

Page speed (also called ‘load speed’) measures how fast the content of a page loads, and it is an important SEO ranking factor on both desktop and mobile [15]. Common page speed metrics include Time to First Byte (TTFB), First Contentful Paint (FCP), and Onload time [15]. Google’s Core Web Vitals are a set of metrics that measure user experience, including Largest Contentful Paint (LCP), First Input Delay (FID), and Cumulative Layout Shift (CLS) [15].

Tools to check page speed include:

  • Google PageSpeed Insights
  • Google Lighthouse
  • WebPage Test
  • Pingdom Website Speed Test
  • GTmetrix
  • Semrush’s Website Speed Test [15]

Ways to improve page speed include:

  1. Compressing images: Reducing the file size of images can significantly improve page load times.
  2. Reducing HTTP requests: Minimizing the number of requests required to load a page can enhance performance.
  3. Minifying JavaScript, CSS, and HTML: Removing unnecessary characters and code from these files can reduce their size and improve load times.
  4. Enabling browser caching: Storing certain files on the user’s device can reduce the need to reload them on subsequent visits, improving page speed.
  5. Using a Content Delivery Network (CDN): Distributing content from geographically diverse servers can improve page load times for users in different locations.

Other techniques to optimize page speed include:

  • Enabling compression (using Gzip for CSS, HTML, JavaScript files over 150 bytes, but not for images) [16]
  • Reducing redirects, which add extra time for the HTTP request-response cycle [16]
  • Leveraging browser caching to reduce the need to reload certain files [16]
  • Optimizing images by ensuring they are the right size and format, and using CSS sprites [16]
  • Moz Pro’s Site Crawl can help identify slow-loading pages that need to be optimized [16]

Google uses page speed as a ranking signal in its algorithm, and slow page speed can negatively impact indexation, bounce rates, average time on page, and conversions [16]. Therefore, it is crucial to prioritize page speed optimization as part of your technical SEO strategy.
