1. Website Crawlability and Indexing
Website crawlability and indexing ensure that search engines can access, discover, and store your website pages in their database. If your pages are not crawlable or indexed, they will not appear in search results.
Crawlability refers to a search engine’s ability to scan your website using bots, while indexing means storing those pages so they can rank for relevant keywords. Technical SEO optimization helps remove barriers that prevent proper crawling and indexing.
Technical SEO checklist for crawlability and indexing:
- Ensure important pages are not blocked in robots.txt
- Submit XML sitemap to Google Search Console
- Check indexed pages using the site: operator in Google
- Fix crawl errors and broken pages
- Avoid orphan pages without internal links
- Use proper internal linking to connect pages
Improving website crawlability and indexing helps search engines understand your website structure, improves visibility, and increases your chances of ranking higher in search results.
2. XML Sitemap Optimization
An XML sitemap is a file that lists all important pages on your website and helps search engines discover and index them faster. It acts as a roadmap that guides search engines to your content and improves website crawlability and indexing.
XML sitemap optimization is an essential part of technical SEO because it ensures search engines can find your most important pages. Without a properly configured sitemap, some pages may not be discovered or indexed.
Technical SEO checklist for XML sitemap optimization:
- Ensure XML sitemap exists on your website
- Submit sitemap in Google Search Console
- Include only important and indexable pages
- Remove broken, duplicate, or redirected URLs
- Update sitemap automatically when new pages are added
- Ensure sitemap uses correct canonical URLs
A properly optimized XML sitemap improves website SEO by helping search engines crawl your website more efficiently, index pages faster, and improve your overall search rankings.
3. Robots.txt Optimization
Robots.txt is a file that tells search engines which pages they can crawl and which pages they should avoid. It helps control search engine access and ensures important pages are properly crawled and indexed.
Robots.txt optimization is critical for technical SEO because incorrect settings can block search engines from accessing important pages. This can prevent your website from appearing in search results and reduce your website SEO performance.
Technical SEO checklist for robots.txt optimization:
- Ensure robots.txt file exists on your website
- Allow access to important pages and sections
- Do not block SEO critical pages
- Add XML sitemap link in robots.txt
- Block only unnecessary or private pages
- Test robots.txt in Google Search Console
A properly optimized robots.txt file improves website crawlability, protects sensitive pages, and ensures search engines can access and index your website efficiently.

4. Website Speed Optimization (Core Web Vitals)
Website speed optimization improves how fast your website loads and responds to users. It is a critical technical SEO factor because search engines prioritize fast loading websites that provide a better user experience.
Core Web Vitals are key performance metrics used by Google to measure website speed and usability. These include Largest Contentful Paint, Interaction to Next Paint, and Cumulative Layout Shift. Websites that perform well in these metrics have better chances of ranking higher in search results.
Technical SEO checklist for website speed optimization:
- Optimize and compress images
- Enable browser caching
- Minify CSS, JavaScript, and HTML
- Use fast and reliable hosting
- Use a Content Delivery Network
- Reduce unnecessary scripts and plugins
Improving website speed helps search engines crawl your website faster, improves user experience, reduces bounce rate, and improves website SEO and rankings.
5. Mobile Friendliness Optimization
Mobile friendliness optimization ensures your website works properly on smartphones and tablets. Google uses mobile first indexing, which means it primarily evaluates the mobile version of your website for ranking and indexing.
A mobile friendly website improves user experience, increases engagement, and helps search engines crawl and index your content efficiently. Websites that are not optimized for mobile devices may experience lower rankings and reduced visibility in search results.
Technical SEO checklist for mobile friendliness optimization:
- Use responsive website design
- Ensure content fits all screen sizes
- Use readable font sizes
- Make buttons easy to tap
- Optimize mobile loading speed
- Avoid elements that break on mobile devices
Improving mobile friendliness helps improve website SEO, enhances user experience, and increases your chances of ranking higher in mobile and desktop search results.
6. HTTPS and Website Security
HTTPS ensures your website is secure and protects data exchanged between users and your website. It is an important technical SEO factor and a confirmed Google ranking signal. Secure websites are trusted more by both search engines and users.
HTTPS uses an SSL certificate to encrypt information, which protects user data and prevents security warnings in browsers. Websites without HTTPS may be marked as not secure, which can reduce trust and negatively impact rankings.
Technical SEO checklist for HTTPS and website security:
- Install a valid SSL certificate
- Ensure all pages use HTTPS
- Redirect HTTP URLs to HTTPS
- Fix mixed content issues
- Ensure secure internal links
- Monitor SSL certificate validity
Improving website security helps search engines trust your website, improves user confidence, and strengthens your website SEO and search rankings.
7. Fix Broken Links and Errors
Broken links and website errors prevent search engines from crawling your pages and reduce your website SEO performance. These errors create a poor user experience and can stop important pages from being indexed and ranked.
Broken links usually result in 404 errors, which occur when a page no longer exists or the URL is incorrect. Search engines may reduce crawl efficiency if your website contains too many errors or broken internal links.
Technical SEO checklist for fixing broken links and errors:
- Identify and fix 404 error pages
- Fix broken internal links
- Update or remove broken external links
- Fix incorrect URLs
- Use proper redirects for moved pages
- Monitor errors in Google Search Console
Fixing broken links improves website crawlability, ensures proper indexing, and helps search engines access your pages efficiently, which improves website SEO and rankings.
8. URL Structure Optimization
URL structure optimization ensures your website URLs are clean, readable, and easy for search engines to understand. SEO friendly URLs help search engines identify page content and improve crawlability, indexing, and rankings.
Well optimized URLs include relevant keywords and avoid unnecessary parameters, numbers, or symbols. Clean URL structure also improves user experience and increases click through rates in search results.
Technical SEO checklist for URL structure optimization:
- Use short and descriptive URLs
- Include primary keyword in the URL
- Avoid unnecessary parameters and numbers
- Use hyphens to separate words
- Keep URL structure consistent
- Avoid duplicate URL versions
Optimized URL structure helps search engines understand your pages better, improves website SEO, and increases your chances of ranking higher in search results.
9. Internal Linking Optimization
Internal linking optimization helps search engines discover, crawl, and understand the relationship between your website pages. It connects your content and ensures important pages receive more visibility and authority in search results.
Internal links help search engines prioritize key pages and improve indexing efficiency. They also guide users to related content, which improves user experience and increases time spent on your website.
Technical SEO checklist for internal linking optimization:
- Link important pages from relevant content
- Use descriptive and keyword relevant anchor text
- Avoid orphan pages without internal links
- Link from high authority pages to important pages
- Maintain logical website structure
- Regularly audit and update internal links
Strong internal linking improves website crawlability, strengthens page authority, and helps improve website SEO and search engine rankings.
10. Fix Duplicate Content Issues
Duplicate content occurs when the same or similar content appears on multiple URLs. This confuses search engines and makes it difficult to determine which version should be indexed and ranked. Duplicate content can reduce rankings and weaken website SEO performance.
Technical SEO optimization helps prevent duplicate content by ensuring search engines index the correct version of each page. This improves crawl efficiency and protects your website authority.
Technical SEO checklist for fixing duplicate content issues:
- Use canonical tags to define the preferred page version
- Avoid multiple URLs for the same content
- Redirect duplicate pages to the original page
- Maintain consistent URL structure
- Avoid duplicate title tags and meta descriptions
- Check duplicate pages using SEO audit tools
Fixing duplicate content helps search engines index the correct pages, improves website crawlability, and strengthens your website SEO and rankings.
11. Structured Data and Schema Markup Optimization
Structured data is code added to your website that helps search engines understand your content more clearly. It improves how your pages appear in search results and increases your chances of getting rich results such as FAQs, reviews, and featured snippets.
Schema markup is an important part of technical SEO optimization because it provides additional information about your pages. This helps search engines categorize your content correctly and improves visibility in search results and AI powered search engines.
Technical SEO checklist for structured data optimization:
- Add schema markup to important pages
- Use Article schema for blog content
- Use Organization schema for business information
- Use FAQ schema for question based content
- Use Breadcrumb schema for website structure
- Test schema using structured data testing tools
Structured data improves website SEO, enhances search visibility, and helps search engines and AI systems understand and rank your content more effectively.
12. Website Architecture Optimization
Website architecture refers to how your website pages are organized and connected. A clear and logical website structure helps search engines crawl your website efficiently and understand the importance of each page.
Good website architecture ensures important pages are easy to find and accessible within a few clicks from the homepage. This improves crawlability, indexing, and overall website SEO performance.
Technical SEO checklist for website architecture optimization:
- Organize pages in a clear and logical structure
- Keep important pages close to the homepage
- Use proper internal linking between related pages
- Avoid deep page hierarchy
- Ensure all pages are accessible to search engines
- Maintain consistent navigation across the website
Optimizing website architecture improves crawl efficiency, strengthens page authority, and helps improve website SEO and search engine rankings.
