Technical SEO for your site to perform best results

Technical SEO is the foundation of a website’s optimization efforts that ensure its functionality, structure, and performance meet the requirements of search engine crawlers like Googlebot (Google's web crawler) and Bingbot (Microsoft Bing’s web crawler). The more optimized your website is technically, the easier it is for search engines to crawl, index, and rank your content. Technical SEO encompasses a wide range of factors, including the communication between your website and search engine bots, the site's structure, server configuration, and more. In this article, we’ll walk through the basics to advanced technical SEO strategies and techniques that will help your website rank well in Google and Microsoft Bing search engines.

You probably already know: If not indexed by Google, your Website will not appear for any queries. And you won't get any organic traffic at all.


That's why you're here, right? Then we get to work right away! In this article, I'll show you how to fix any of the following three:
  1. Your entire Web site has not been indexed by Google.
  2. Some pages have Google indexed, but others don't.
  3. Recently published web pages index is slow.

What is crawling and the Google Index?

Google discovered several new Web sites by crawling the Web. They then add those pages to their index. They do this using a "spider web" called Googlebot.

  1. Information gathering (also known as "scratching"): The process of monitoring hyperlinks on the Web to discover new content.
  2. Indexing: The process of storing every Web page in a large database.
  3. Spider web: A piece of software designed to perform large-scale information collection.
  4. Googlebot: Google's spider web.

When you Google something, you are asking Google to return all relevant pages from their index. Because there are often millions of pages that fit the bill. So Google's ranking algorithm will do its best to organize the pages so that you see the best and most relevant results first.

The important point that I want to say here is that the Google index and ranking are two different things.
Index is registering for a race, and ranking is a winner. You can't win without appearing in the race in the first place, right?
So now let's see how to "register in" this ranking race.

How to check if you got Google Index or not

  • First, go to Google, then search for your Web site using "site:" + "website you want to find".
  • For example my website is FAMEMEDIA.VN. You will type site:famemedia.vn on Google

Introduction to Technical SEO

Technical SEO refers to the processes and practices used to optimize a website’s infrastructure to make it more accessible, understandable, and user-friendly for search engines. While on-page SEO focuses on optimizing the content of a website, and off-page SEO focuses on improving external signals like backlinks, technical SEO deals with the backend, ensuring that the website performs well in terms of speed, crawlability, mobile compatibility, and security.

At its core, technical SEO helps search engines understand how to crawl, index, and rank your site effectively. It’s critical because if search engines cannot properly crawl and index your website, even the best content and backlinks won't help you rank.

Why Technical SEO Matters

Technical SEO is important because it enables search engines like Google and Bing to efficiently crawl and index your content, which directly impacts your rankings. Without technical SEO, even great content may be overlooked or improperly indexed, resulting in poor search engine rankings.

Here are a few key reasons why technical SEO matters:

  • Improved Crawlability and Indexing: Search engines like Google and Bing rely on bots to discover and index your web pages. If your website is not optimized for crawling, these bots may miss crucial pages, which negatively impacts your rankings.

  • Better User Experience (UX): Technical SEO focuses on improving the website's load speed, mobile-friendliness, and overall functionality, leading to a better user experience, which indirectly impacts SEO performance.

  • Increased Site Speed: A faster-loading website improves user experience and has been confirmed by Google as a ranking factor. Sites that load slowly often have higher bounce rates and lower rankings.

How Web Crawlers Work

Search engines rely on web crawlers (also known as bots or spiders) to explore and index websites. These crawlers act like virtual robots that browse the internet, discover new content, and send it back to the search engine's index

Key Crawling Concepts:

  • Crawl Budget: This refers to the number of pages a search engine will crawl on your website during a given time frame. Efficient technical SEO practices ensure that your crawl budget is spent wisely, with search engines prioritizing important pages.

  • Crawl Depth: The number of clicks or hops a crawler needs to make from the homepage to find a specific page. The shallower the crawl depth, the better the page’s chances of being crawled.

  • Crawl Frequency: The rate at which a search engine revisits your site to check for changes or new content.

Both Googlebot and Bingbot use a series of algorithms to determine which pages to crawl and how often. These bots interpret data from your site’s robots.txt file, meta tags, HTTP headers, and other technical aspects to decide which pages should be indexed and which should be excluded.

Key Technical SEO Factors

Site Architecture and Structure

The structure of your website is one of the first things search engine bots will analyze. A well-organized site structure helps search engines find and understand the content easily. Here are a few best practices for a clean website structure:


  • Hierarchy and Navigation: Your website should have a clear hierarchy. Ensure your primary navigation menu is simple and straightforward, with important content accessible in just a few clicks.

  • Internal Linking: Strategically link related pages within your site. This not only helps search engines discover new pages but also helps distribute link equity.

  • URL Structure: Ensure your URLs are clean, descriptive, and user-friendly. Short URLs that include relevant keywords tend to perform better in search rankings.

Website Speed Optimization

Page speed is a critical ranking factor for Google, and it is also important for Bing. Websites that load quickly provide a better user experience, which can lead to lower bounce rates and higher conversions.


Ways to improve website speed:

  • Image Optimization: Compress images without losing quality to reduce load times.
  • Minimize HTTP Requests: Reduce the number of elements on a page to limit the number of HTTP requests.
  • Enable Browser Caching: Store resources locally in the user's browser to speed up future page visits.
  • Use a Content Delivery Network (CDN): Distribute your website’s static files across multiple servers to ensure faster load times for users from different regions.

Mobile Optimization

Mobile optimization is no longer optional. Google and Bing both use mobile-first indexing, which means they primarily use the mobile version of your website for ranking and indexing. If your website isn’t optimized for mobile devices, your rankings will suffer.


Mobile Optimization Tips:

  • Use responsive design to ensure your site looks good on all devices.
  • Test your website using tools like Google’s Mobile-Friendly Test to ensure a smooth mobile experience.
  • Optimize content for smaller screens by keeping text legible and buttons easily clickable.

SSL/HTTPS Security

Security is a critical ranking factor. Google prioritizes secure websites, and Bing also gives preference to HTTPS over HTTP sites. Having an SSL certificate on your website ensures that the data exchanged between the server and the user is encrypted.


Benefits of SSL/HTTPS:

  • User Trust: Users are more likely to trust a website with a secure connection.
  • Improved Rankings: Both Google and Bing give HTTPS sites an SEO boost.

Robots.txt File and Crawling

The robots.txt file is a simple text file placed on your website that gives instructions to search engine crawlers about which pages they should or shouldn’t crawl. It’s a powerful tool for controlling crawler behavior.


Best practices for robots.txt:

  • Block crawlers from accessing duplicate or irrelevant content, such as login pages or admin panels.
  • Don’t block important pages that you want to rank, such as product or blog pages.
  • Use the noindex directive in meta tags for specific pages you don’t want to be indexed but still need crawlers to access.

Sitemap.xml

A sitemap.xml file is a roadmap that helps search engines discover all of your website’s pages. It provides essential metadata about your pages, including how often they are updated and how important they are.


Best Practices for Sitemaps:

  • Ensure your sitemap is up to date with all your important pages listed.
  • Submit your sitemap to Google Search Console and Bing Webmaster Tools for faster crawling and indexing.
  • Make sure the sitemap is accessible and doesn’t contain broken links.

Structured Data and Schema Markup

Structured data (or schema markup) is code that you can add to your website to provide search engines with additional context about your content. This helps search engines understand the meaning of the content and can lead to rich snippets in search results (e.g., star ratings, product prices, etc.).


Benefits of Structured Data:

  • Enhanced Visibility: Rich snippets increase your visibility in SERPs and improve CTR.
  • Better Understanding: Schema helps Google and Bing interpret your content more accurately.

Canonical Tags

A canonical tag is used to prevent duplicate content issues by telling search engines which version of a page should be indexed. If you have multiple pages with similar content, canonical tags point to the “preferred” version.


When to Use Canonical Tags:

  • When you have duplicate pages with similar content.
  • For pages with URL parameters, like e-commerce filter pages.
  • On content syndication or repurposed content.

Advanced Technical SEO Strategies

Core Web Vitals

Core Web Vitals is a set of user-centered metrics introduced by Google to measure real-world user experience on websites. These include metrics like Largest Contentful Paint (LCP), First Input Delay (FID), and Cumulative Layout Shift (CLS). Optimizing these metrics can improve your website's user experience and rankings.


JavaScript SEO

JavaScript-heavy websites can be difficult for search engines to crawl and index. Use server-side rendering (SSR) or static site generation (SSG) to make sure search engine crawlers can access the content.


Crawl Budget Optimization

Crawl budget refers to how much time and resources search engines allocate to crawling your site. To make sure your important pages are crawled, you should:


  • Remove duplicate content.
  • Block crawlers from irrelevant pages.
  • Optimize your internal linking to help bots find important content faster.

Pagination and Infinite Scroll Optimization

If your site uses pagination (for multi-page content) or infinite scroll, you need to ensure that search engines can crawl and index all pages properly. Implement rel="next" and rel="prev" tags for paginated content and use the pushState API for infinite scroll.


International SEO Considerations

If your website targets multiple regions or languages, use hreflang tags to tell Google and Bing which version of a page should be shown to users based on their language and location.


Monitoring Technical SEO Performance

Monitor your technical SEO performance using tools like Google Search Console, Bing Webmaster Tools, Ahrefs, and SEMrush. These tools provide valuable insights into your website’s crawlability, indexing status, and overall performance.


Communication Between Website and Search Engine Bots

Effective communication between your website and crawlers is vital. Here’s how you can manage bot access:


  • Robots.txt: Use this file to instruct crawlers which pages to crawl or avoid.
  • Meta Tags: Use noindex, nofollow, noarchive to instruct search engines about indexing and following links.
  • HTTP Headers: Server-side directives like X-Robots-Tag can control crawling and indexing for non-HTML content, such as PDFs or images.

Conclusion

Technical SEO is the backbone of a website’s ability to rank in Google and Bing search engines. By ensuring that your site is optimized for crawling, fast loading, mobile-friendly, secure, and well-structured, you set the stage for search engines to effectively index and rank your content. From basic settings like robots.txt files and sitemaps to advanced strategies like Core Web Vitals and JavaScript SEO, technical SEO plays a vital role in achieving high search engine rankings and providing a seamless user experience.
