What Is Technical SEO?
Technical SEO enhances a website’s backend elements and architecture for better search engine visibility. It involves optimizing code, improving crawlability, and resolving issues like broken links and metadata errors.
A technical SEO audit is typically the first and most extensive step in any SEO campaign. It lays the foundation for all optimization efforts by ensuring the website’s structure, navigation, and code are in optimal condition.
Without addressing technical issues first, other SEO activities, such as content optimization and link building, may not yield the desired results. Prioritizing technical SEO is essential to elevate the overall user experience, engagement, and website performance.
Understanding Crawling and Indexing
Two critical aspects of technical SEO are crawlability and indexability, which directly impact how search engines like Google discover, interpret, and rank your web pages.
Search engines use bots, also known as spiders or crawlers, to find and rank web pages. These automated programs discover websites on the internet, assess their content, follow any links on the site, and gather information about the page’s relevance and quality. This data is then processed and stored in a vast database known as the index.
The index serves as the foundation for search engine algorithms to determine the most relevant and authoritative pages for specific search queries. When users conduct searches, the search engine’s algorithm sifts through the index, evaluating numerous factors such as content quality, relevance, authority, and user experience to deliver the most useful results.
For your website to appear in search engine results pages (SERPs), it needs to be crawlable and indexable.
Crawlability
– Crawlability refers to how easily search engine crawlers can access and navigate your website’s content. An essential aspect of crawlability is having a well-structured website with clear navigation and URL hierarchy.
– Technical SEO strategies for improving crawlability include creating XML sitemaps, optimizing robots.txt files to guide crawler behavior, and using internal linking effectively to ensure all pages are accessible.
– Issues like broken links or overly complex website structures can hinder crawlability, leading to incomplete indexing and reduced visibility in search results.
Indexability
– Indexability ensures that search engines can accurately interpret your content, making them eligible to appear in relevant search results.
– Technical SEO practices that enhance indexability include optimizing meta tags (title tags and meta descriptions) with relevant keywords and information, using canonical tags to resolve duplicate content issues, and implementing structured data markup for enhanced search result features.
If your webpages aren’t readable and indexable by crawlers, you risk missing out on valuable traffic from Google’s search results. This missed opportunity translates into lost leads and revenue for your business.
Technical vs. On-Page vs. Off-Page SEO: What’s the Difference?
On-page, off-page, and technical SEO are all equally important in advancing your search rankings. Neglecting any of these pillars can lower your rankings, which is why understanding their differences is crucial.
– On-page SEO: Involves improving website content within your control. These include headers, product descriptions, and blog posts. It’s about formatting your website to match search queries, creating a positive experience for visitors and search engines alike.
– Off-page SEO: Refers to search engine marketing activities that occur outside your website. These tactics aim to enhance your website’s reputation, domain authority, and relevance across the web. They include activities like link building, content marketing, guest posting, brand building, and social media marketing. Neglecting off-page SEO can hinder your site’s ability to surpass higher-authority websites in search rankings, regardless of how well your on-page SEO efforts are.
– Technical SEO: Focuses on activities that aid Google bots in effectively crawling, reading, and indexing all your webpages.
By combining these strategies, you create a well-rounded approach that signals to search engines that your website is trustworthy, relevant, updated, and user-centric.
Your Complete Technical SEO Checklist
Now that we’ve answered, “What is technical SEO,” it’s time to put theory into action.
With Google considering over 200 ranking factors, SEO tasks can seem overwhelming. This technical SEO checklist ensures no vital step is overlooked.
Page Loading Time
Time is critical online. About 86% of marketers cite slow site speed as the top reason visitors leave a website (GoodFirms). Think with Google adds that when page load time hits 10 seconds, bounce rates can skyrocket by up to 123%.
“Fast-loading webpages are essential to your website. They affect user experience and conversion rates. You don’t want your audience to wait for more than three seconds to load your website,” said Ronnel Viloria, Breakloo Digitals’ Demand Generation Lead SEO Strategist.
Google’s Speed Test offers a swift analysis of your website’s loading speed. Over the years, the tool has evolved to reveal key metrics, including:
– First Contentful Paint (FCP): Measures how long it takes for the first content element to appear on the screen. A fast FCP indicates quick initial loading and a better user experience.
– Time to Interactive (TTI): Quantifies the time it takes for a web page to become fully interactive, allowing users to engage with elements like buttons or forms. A shorter TTI improves user engagement and satisfaction.
– Cumulative Layout Shift (CLS): Measures the amount of unexpected layout shifts that occur during page load.
– Largest Contentful Paint (LCP): Refers to the loading time of the largest content element on the screen.
These metrics pinpoint specific areas for improvement, helping you prioritize your efforts and allocate resources effectively.
There are several things you can do to improve page loading speed:
- Reduce Server Response Time
Server response time, also known as Time to First Byte (TTFB), is the duration from when a client requests a page in a browser to when the server responds to that request. Essentially, the better the TTFB, the higher your search ranking.
Improve TTFB by investing in a reliable and fast web hosting service. Ensure that your hosting provider has the capacity to handle your website’s data needs. Scalability is crucial, especially for commercial sites like eCommerce stores that experience traffic spikes during peak times. Your web host should be capable of scaling server resources to ensure rapid and consistent performance 24/7.
- Optimize Image Size Without Compromising Quality
Unoptimized images are a major contributor to slow site speeds, accounting for up to 75% of a page’s weight. Images consume a significant amount of data on a webpage, causing the server to take longer to load. Minimizing the amount of downloaded data leads to faster content rendering on the screen.
– Opt for the Right Format: When aiming to reduce image size, consider using lossless formats such as PNG or TIFF. These formats preserve image quality better compared to lossy formats like JPEG.
– Maintain Aspect Ratio: Always ensure the aspect ratio (width-to-height ratio) remains intact when decreasing image size. This prevents distortion and maintains image integrity.
– Consider Cropping: Cropping a portion of an image is preferable to resizing since it does not compromise quality.
– Remove Unnecessary Metadata: Eliminate unnecessary image metadata, such as camera information and settings. This reduces image file size without affecting visual quality.
- Minimize Render-Blocking Javascript and CSS
Render-blocking resources are static files like fonts, HTML, CSS, and JavaScript. However, when the browser encounters these resources, it halts the download of other resources until these critical files are processed. This delay can lead to slower loading times, disrupting the user’s browsing experience.
By minimizing render-blocking resources, you can shorten the critical rendering path and decrease page load times. There are different ways to lower the number and impact of render-blocking resources:
– Utilize Deferred Loading: Employ techniques like async and defer attributes for scripts to allow them to load without obstructing page rendering.
– Minify and Combine Files: Reduce the number of CSS and JavaScript files by combining and minifying them. This reduces HTTP requests and file sizes, improving load times.
– Split Code Into Smaller Bundles: Divide your code into smaller bundles and load each bundle on demand or in parallel. This includes non-essential resources that can be lazy-loaded after the page has rendered or only loaded when specific features are needed.
– Remove Unused Code: Identify and eliminate unused JavaScript and CSS code to reduce bloat. WordPress offers cleanup plugins for automated removal of unused resources.
- Decrease the Number of Resources and HTTP Requests
When a user visits your website, the server receives a request to access the necessary files. These HTTP requests directly impact the web page’s load time. Larger files result in longer response times for the requested action. Likewise, rapid and multiple requests can significantly slow down a server.
Follow these steps to check your HTTP requests:
– Open an Incognito tab in Chrome.
– Right-click and select Inspect.
– Navigate to the network subtab.
– Press F5 to refresh the page.
– This
process allows you to assess the number of HTTP requests on the network.
If your site has over 50 HTTP requests, you should investigate which resources are making the most requests. It’s advisable to audit your website thoroughly and eliminate any superfluous elements that may negatively impact its performance.
- Decrease Time to First Byte (TTFB)
Improving TTFB is essential for optimizing server performance and enhancing user experience. This can be achieved through a multi-faceted approach, focusing on efficient server-side processing, robust content delivery networks (CDNs), and streamlined backend infrastructure.
– Efficient Server-Side Processing: Optimize server code and database queries to minimize processing time. Utilize caching mechanisms to store frequently requested data, reducing the need for repeated processing and enhancing response times.
– Content Delivery Networks (CDNs): Implement a CDN to distribute content across multiple servers strategically located around the globe. This reduces the distance between the user and the server, resulting in faster content delivery and reduced TTFB.
– Backend Infrastructure Streamlining: Regularly audit and optimize backend infrastructure, ensuring that servers, databases, and applications are running at peak efficiency. Implement load balancing to evenly distribute traffic and prevent bottlenecks that can slow down response times.
– Protocol Optimization: Utilize modern protocols such as HTTP/2 or HTTP/3, which offer improved performance through features like multiplexing, header compression, and reduced latency. These protocols enhance TTFB by facilitating faster and more efficient data transfer between client and server.
By integrating these strategies, you can significantly enhance TTFB, leading to faster page loading times, improved user satisfaction, and better overall website performance.
- Implement Content Delivery Network (CDN)
A Content Delivery Network (CDN) is crucial for enhancing website speed and reliability. It achieves this by distributing web content across multiple servers located worldwide. These servers, strategically positioned in key geographic regions, enable faster content delivery by serving users from the closest server to their location.
CDNs improve website performance through several key mechanisms:
– Reduced Latency: CDNs minimize latency by reducing the distance between the user and the server. This results in faster loading times and an overall improved user experience.
– Load Balancing: CDNs distribute traffic across multiple servers, preventing any single server from becoming overwhelmed. This ensures consistent performance, even during peak traffic periods.
– Caching: CDNs cache frequently accessed content on their servers, reducing the need to fetch data from the origin server repeatedly. This decreases the load on the origin server and accelerates content delivery.
- Enable Browser Caching
Browser caching is a technique that allows web browsers to store copies of web pages, images, stylesheets, and other resources locally on a user’s device. This reduces the need to re-download these resources from the server on subsequent visits, significantly improving page load times.
Implementing browser caching involves specifying cache control headers that instruct browsers on how long to store specific resources. By setting appropriate cache expiration times, webmasters can ensure that static content, such as images and stylesheets, remains cached for an extended period, while dynamic content is updated more frequently.
To enable browser caching, webmasters can add cache control directives to their server configuration or utilize content management system (CMS) plugins designed for caching optimization.
Here are practical steps to enable browser caching:
– Configure Cache Headers: Set cache control headers for different types of resources, specifying the duration for which they should be stored in the browser cache. Use directives like “max-age” to define the expiration time.
– Leverage Expires Headers: Utilize Expires headers to set expiration dates for specific resources. This informs browsers to cache resources until the specified date, reducing the need for repeated requests.
– Implement Cache-Busting Techniques: When updating resources, use cache-busting techniques such as versioning or appending query strings to filenames. This ensures that browsers fetch the latest version of the resource, preventing stale content from being displayed.
– Utilize CMS Plugins: If using a content management system like WordPress, leverage caching plugins that simplify the process of enabling browser caching. These plugins often provide user-friendly interfaces to configure cache settings.
- Compress Your Files
Website compression enhances page speed by reducing the size of HTML, CSS, and JavaScript files, leading to faster loading times and improved user experiences.
Implementing GZIP compression, a popular and effective method, involves compressing files on the server before sending them to the user’s browser. This reduces file sizes, enabling quicker data transmission and more efficient use of server resources.
To enable GZIP compression, configure your web server settings. On Apache servers, this is done through the .htaccess file by adding directives to enable GZIP compression. On NGINX servers, modify the configuration file to activate GZIP compression.
Tools like Google PageSpeed Insights and GTmetrix can help monitor the effectiveness of your compression efforts, providing insights into file sizes and compression ratios. Regularly reviewing these metrics ensures that your website maintains optimal performance.
By implementing file compression techniques like GZIP, you can significantly enhance page speed, reduce bandwidth usage, and deliver a smoother, faster user experience.
Website Functionality & Usability
Implement an SSL Certificate
An SSL certificate secures user data, validates website ownership, and prevents cybercriminals from creating fake versions of your site.
When installed, SSL activates the HTTPS protocol, providing a secure connection between the server and the user’s browser. This encryption ensures that sensitive information, such as passwords and credit card details, remains private during transmission.
The benefits of SSL certificates extend beyond security:
– Improved Search Engine Rankings: Google considers SSL as a ranking factor, prioritizing secure websites in search results. Websites with SSL certificates may experience improved visibility and higher search engine rankings.
– Enhanced User Trust: SSL certificates instill confidence in users, assuring them that their data is safe. The presence of a padlock icon and “HTTPS” in the address bar signals a secure connection, fostering trust and credibility.
