#1. Crawlability

Crawlability is an important factor in technical SEO, as it determines how easily search engine bots can access and index a website. Crawlability refers to the ability of search engine bots (such as Googlebot) to access and navigate your website’s content efficiently. Good crawlability is essential for search engines to be able to discover your website’s content, thus increasing the chances of achieving higher rankings in search results. In other words, good crawlability ensures that your website’s content gets discovered by search engines.

How to Improve Crawlability?

To enhance your website’s crawlability, follow these best practices:

  • Create a clear site structure: Organize your content into categories with descriptive URLs that make sense both for users and search engines.
  • Implement internal linking: Use relevant anchor text when linking between pages within your site so that crawlers can understand their relationship.
  • Create an XML sitemap: An XML sitemap helps crawlers discover new or updated pages more quickly by providing a list of all URLs on your site and metadata, such as the last modification date or priority level. Learn how to create an XML sitemap here.
  • Avoid duplicate content: Duplicate content can confuse search engine bots and lead to indexing issues. Use canonical tags or 301 redirects to resolve duplicate content problems.
  • Optimize your robots.txt file: A well-configured robots.txt file allows you to control which pages crawlers should access and which ones they should ignore. Ensure not to block important resources needed for rendering your site.

Common Crawlability Issues and Solutions

Here are some common crawlability issues that may affect your website’s SEO performance, along with their solutions:

  • Bots blocked by the robots.txt file: Ensure you’re not accidentally blocking search engines from crawling essential parts of your site in the robots.txt file.
  • Broken links or orphaned pages: Regularly audit your website for broken links or unlinked pages using tools like Screaming Frog SEO Spider. Fix any discovered issues by updating URLs, implementing redirects, or adding relevant internal links.
  • Javascript-heavy websites: If your website relies heavily on Javascript for navigation or displaying content, make sure it is accessible without JS enabled. You can use Google’s Fetch & Render tool To test how a page appears without JavaScript enabled.

#2. Performance

Website performance is essential for providing a good user experience and improving SEO rankings. Performance refers to the speed at which a website loads and responds to user interactions. A speedy website enhances the user experience and boosts search engine rankings, as Google looks at page loading speed as one of its ranking criteria. Factors affecting website performance include server response time, image optimization, code minification, and caching strategies.

How to Improve Performance?

To enhance your website’s performance and ultimately boost your SEO efforts, consider implementing the following best practices:

  • Optimize Images: Compress images using tools like TinyPNG, or serve them in next-gen formats such as WebP for faster loading times.
  • Minify Code: Minify HTML, CSS & JavaScript files by removing unnecessary characters (like whitespace) without affecting functionality using tools like Google’s Minify Resources guide.
  • Caching Strategies: Implement browser caching techniques or use Content Delivery Networks (CDNs) like Cloudflare or Amazon CloudFront to store cached versions of your site across multiple servers worldwide for quicker access by users from different locations.
  • Leverage Lazy Loading: Load images or other media assets only when needed (i.e., when they come into the viewport) using JavaScript libraries like lazy sizes.
  • Enable Compression: Use Gzip or Brotli compression to reduce the size of your website’s files, thus speeding up their transfer time.

Common Performance Issues and Solutions

Beyond implementing best practices, it is crucial to identify and address common performance issues hindering your site’s load times. Some typical problems include:

  • Slow Server Response Time: Opt for a reliable hosting provider with fast server response times or upgrade your hosting plan if needed.
  • Inefficient Code Execution: Review and optimize any custom code on your site, ensuring efficient execution by removing unnecessary loops or function calls.
  • Lack of Browser Caching: Enable browser caching through proper HTTP headers configuration to store static assets locally on users’ devices for faster subsequent page loads.
  • Poorly Optimized Database Queries: Monitor database queries using tools like MySQL Slow Query Log or New Relic APM (Application Performance Monitoring), then optimize them accordingly by adding indexes where necessary or refactoring complex queries into simpler ones. 
  • Indexation : Indexation refers to indexing web pages by search engines so they can appear in search results. Ensuring your website is properly indexed is crucial for achieving high visibility and attracting organic traffic from search engine users. Indexation involves discovering, processing, and storing webpages by search engines like Google or Bing into their respective databases (also known as “index”). When a user performs a query on a search engine, the algorithm retrieves relevant pages from its index to display on the results page. Therefore, if your website isn’t indexed appropriately or not at all, it won’t be accessible to potential viewers searching for related material.

 How to Improve Indexation?

To ensure proper indexing of your website’s content by major search engines such as Google, follow these best practices:

  • Create an XML Sitemap: An XML sitemap provides a roadmap for crawlers with information about your site structure and important URLs you want them to discover quickly.
  • Submit Your Sitemap: Once created, submit your sitemap through Google Search Console (GSC) or Bing Webmaster Tools (BWT) so that they know its existence.
  • Maintain Clean URL Structures: Keep URLs short but descriptive while avoiding unnecessary parameters or special characters that may confuse crawlers.
  • Use Canonical Tags: Implement canonical tags to inform search engines about the preferred version of a webpage when there are multiple URLs with similar content, thus avoiding duplicate content issues.
  • Optimize Internal Linking: Ensure your website has a well-structured internal linking system, which helps search engine bots navigate and discover new pages more efficiently.

Common Indexation Issues and Solutions

Beyond implementing best practices for indexation, it’s essential to be aware of common issues that can negatively impact this process. Here are some typical problems you might encounter, along with their solutions:

  • Noindex Meta Tag or Robots.txt Disallow Directive: If you unintentionally block crawlers from accessing specific web pages using these methods, they won’t be indexed. Double-check your meta tags and robots.txt file to ensure proper configuration.
  • Duplicate Content: Having identical or similar content across multiple URLs can confuse search engines regarding which page should be indexed. Use canonical tags or consolidate the information into one URL.
  • Poorly Optimized Site Structure & Navigation: A confusing site structure makes it difficult for users and search engine bots to find relevant pages on your website. Optimize your navigation menu, use descriptive anchor text in links, and create an XML sitemap, as mentioned earlier in this section.

#3. Structured Data & Schema Markup

  • Structured data refers to a standardized format that helps search engines understand the content on your website better by providing explicit clues about its meaning. Schema markup is a form of microdata created by Schema.org. It can be embedded in HTML code to make it easier for search engine crawlers to detect essential information such as contact info, product costs, reviews, etc.
  • Schema markup, on the other hand, is a specific vocabulary of tags (or microdata) developed by Schema.org, which can be added to your HTML code to improve the way search engines read and represent your web pages in SERPs (Search Engine Results Pages). By implementing schema markup correctly on your site’s pages, you increase their chances of being featured in rich snippets or other enhanced results like knowledge panels or carousels.
Structured Data & Schema Markup

How to Implement Structured Data & Schema Markup?

  • Determine which structured data types apply: Visit Schema.org’s full hierarchy page and decide which schemas best fit your website’s content.
  • Add appropriate schema tags: Once you’ve identified relevant schemas for each webpage element that needs marking up with structured data (e.g., address details), add corresponding JSON-LD or Microdata code snippets within the HTML source code.
  • Analyze implementation: Use tools like Google’s Structured Data Testing Tool or the Schema Markup Validator to check if your structured data is implemented correctly and without errors.
  • Monitor search engine results: Keep an eye on how your webpages are displayed in SERPs, looking for improvements such as rich snippets or other enhanced features. This will help you gauge the effectiveness of your schema markup implementation.

Benefits of Structured Data & Schema Markup for SEO

The use of structured data and schema markup can significantly impact a website’s SEO performance by providing several benefits:

  • Better understanding by search engines: By providing explicit information about your content, you make it easier for crawlers to index and understand its context, which may improve rankings.
  • Richer search results: Implementing schema markup increases the likelihood that Google will display rich snippets (e.g., star ratings, event details) or other enhanced result features (e.g., knowledge panels), making your site stand out in SERPs and potentially increasing click-through rates (CTR).
  • Voice search optimization: As voice assistants rely heavily on structured data when answering user queries, implementing appropriate schemas can improve the chances of being featured in voice search results.
  • Faster indexing process: Providing clear information about webpage elements through structured data helps speed up crawling and indexing processes, ensuring that search engines discover new content faster.

#4. Mobile Optimization & Responsive Design

Mobile optimization refers to adjusting your website’s content, layout, and functionality to perform optimally on various screen sizes and devices, such as smartphones or tablets. This includes ensuring that text is readable without zooming in or out, images load quickly, and buttons are easy to tap with fingers instead of a mouse cursor.

On the other hand, responsive design is an approach where a website’s layout adapts dynamically based on the device’s screen size being used by visitors. This ensures that users have an optimal viewing experience regardless of whether they’re browsing from a desktop computer or smartphone.

How to Implement Mobile Optimization & Responsive Design?

  • Create fluid layouts: Use relative units like percentages instead of fixed-width dimensions (pixels) when designing your site’s layout so it can easily adapt across different screen sizes.
  • Select appropriate breakpoints: Breakpoints determine when your site’s layout changes depending on specific screen widths (media queries). Choose these wisely based on common device resolutions rather than random values.
  • Avoid large media files: Optimize images by compressing them and using the right file format (e.g., JPEG, PNG, or WebP) to reduce load times on mobile devices. You can also use Google Lighthouse to identify areas for improvement.
  • Implement mobile-friendly navigation: Make sure your site’s menu is easily accessible and usable on smaller screens by implementing a hamburger menu or other touch-friendly options.
  • Test across multiple devices: Use tools like BrowserStack, Google’s Mobile-Friendly Test, or Chrome DevTools Device Mode to test how your website performs across various screen sizes and browsers.

Benefits of Mobile Optimization & Responsive Design for SEO

The following are some benefits of incorporating mobile optimization and responsive design into your SEO strategy:

  • Better user experience: A well-optimized site ensures that users have an enjoyable browsing experience regardless of their device type, which leads to higher engagement rates, lower bounce rates, and increased conversions.
  • Faster loading times: Optimizing media files reduces load time, improving user satisfaction and positively contributing to search engine rankings, as page speed is a known ranking factor in Google’s algorithm (source). 
  • Higher search visibility: Since April 2015, Google has preferred mobile – friendly websites in its search results. This means that having a responsive design increases the chances of ranking higher on SERPs ( Search Engine Results Pages ) for mobile searches. 
  • Easier website maintenance: By implementing a responsive design, you only need to maintain one version of your site instead of separate versions for desktop and mobile devices. This simplifies updating content and fixing technical issues, saving time and resources in the long run.
